Things done:
- stay closer to the original rendering in canvas
- get rid of the intermediary blur step
- use the new callbacks in the webgl points renderer
- premultiply alpha in the last postprocessing step
Now the shader and program caches are simply arrays of native WebGL created objects.
The WebGLHelper simply takes the sources of the frag and vert shader and produces a program.
This removes 2 classes & reduces the general verbosity of the API.
Also a `getShaderCompilationErrors` was added on `WebGLHelper` to help debug GLSL errors.
Executors are use to render instructions.
They do not contain cod for building instructions.

ol/renderer/vector was using the abstract ReplayGroup type while
referencing replayGroup.addDeclutter(), which was only defined
on the canvas and webgl implementations and was also defined
differently.
- Added JSDoc to getRenderer()
- Cast default options to types
- Cast event to MouseEvent to satisfy tsc. Non mouse/touch events
will simply produce [NaN, NaN]
- Cast to Layer before calling getSource(), as it does not exist
on Base
tsc considers everything in the else block to be of type 'never',
since it thinks that cosh is permanently defined for Math. Casting
back to Math in the else block fixes the error.
Remove 'extent' because the parent Source class does not contain
'extent' on its options or use options.extent in the constructor.
Also removed 'extent' from 'Options' for 'TileSource'.
Fixed constructor docs specifying optional options without a
default value. Fixed malformed @link tag in typedef description.
canvasFunction type was previously declared with the 'this' type
as ImageCanvas, but the 'this' ref was not passed on the scope when
calling the function.
The parent class does not accept an extent on its options. Also
check that the image is an img or video tag before setting the
source as Canvas does not have the src property.
If `VOID` is used, TypeScript is not able to figure out what the function parameters are.
Before:
```
$ npx tsc | wc -l
1188
```
After:
```
$ npx tsc | wc -l
1169
```
I'm not entirely sure that I like this pattern, but there does not
appear to be a better option since TypeScript would recommend:
function(this: SomeClass, ...)
tsdoc does not appear to support an associated annotation for the
function a la @this {SomeClass}.
Remove the following errors from the TypeScript checks:
```
src/ol/pointer/TouchSource.js(231,23): error TS2339: Property 'webkitRadiusX' does not exist on type 'Touch'.
src/ol/pointer/TouchSource.js(232,24): error TS2339: Property 'webkitRadiusY' does not exist on type 'Touch'.
src/ol/pointer/TouchSource.js(233,26): error TS2339: Property 'webkitForce' does not exist on type 'Touch'.
```
The only reference that I've found for these properties is a warning message from Google Chrome:
```
'Touch.webkitRadiusX' is deprecated and will be removed in M47, around November 2015. Please use 'Touch.radiusX' instead.
```
TypeScript doesn't like the current implementation:
```
src/ol/control/MousePosition.js(82,64): error TS2339: Property 'undefinedHTML' does not exist on type 'never'.
```
Some WMTS getCapabilities return <MatrixSet><TopLeftCorner> with more than one whitespace as delimiter between the coordinates. This leads to the layer not being displayed, because the origin_ property of ol.tilegrid.TileGrid is not set.
Error in ol.tilegrid.TileGrid.prototype.getTileCoordForXYAndZ_: JavaScript runtime error: Unable to get property '0' of undefined or null reference
It is often useful in application code to have a way to uniquely identify
and object.
Exposing the OpenLayers mechanism allows for best performance and avoid
unneccessary dirt.
TileWMS objects take a gutter option but do not have a public getter
for it. This makes it convoluted for user code to recreate the object
(ex: in the case of serialization/deserialization).
- the getGutterInternal() method is renamed to getGutter;
- the getGutter(projection) method is renamed to getGutterForProjection,
which is also more explicit.
The getGutter method was not API and is only used by the renderer.
Instead, only prevent default on handled pointerdown events. This makes
the `focus` condition work with interactions that involve dragging on
touch devices.
By overriding getTile() and creating replay and image there, we can do
all preparations earlier and stop creating new tiles when we have maxed
out the frame time budget. It also allows us to get rid of the
drawTileImage override.
In OpenLayers 5, the following features are not supported anymore:
- Google Closure Compiler builds;
- custom builds.
The Google Closure Compiler is only kept for internal type checking.
To remove the following closure compiler warning:
```
Function module$node_modules$rbush$index.default: called with 1 argument(s). Function requires at least 2 argument(s) and at most 2.
```
`ol.tilegrid.WMTS.createFromCapabilitiesMatrixSet` fails when tileMatrix identifiers
are not prefixed by their tileMatrixSet identifier.
Original code by @filipheymans
In order to allow a user to select content within an element with the `.ol-selectable` class the `user-select` CSS property should be `text`.
The current value of `auto` results in a computed value of `none` due to the rule `.ol-viewport, .ol-unselectable` specifying `user-select: none`. According to the [the specification](https://www.w3.org/TR/css-ui-4/#valdef-user-select-auto):
> if the computed value of `user-select` on the parent of this element is `none`, the computed value is `none`
Tested manually on Chromium, Firefox and IE11.
The PDF was only generated AFTER requesting new tiles. When no new tiles where needed,
the callback never completed. Also fixed fitting the correct extent.
Fixes#7830.
This brings canvas polygon hit detection in parity with WebGL, where an
unfilled polygon will not be hit detected hovering inside the polygon.
Fixes#4846
This uses Closure Compiler to create a full build and run type checks.
Currently type errors are reported as warnings and the build is created
with SIMPLE optimizations until we have transitioned all types to path
types.
In rare cases, the previous font check returned false negatives when
checking against monospace only. By checking against another font, this
can be avoided.

## Working with the build tool
As an OpenLayers developer you will use `make` to run build targets defined in the
`Makefile` located at the root of the repository. The `Makefile` includes
targets for running the linter, the compiler, the tests, etc.
The usage of `make` is as follows:
$ make <target>
where `<target>` is the name of the build target you want to execute. For
example:
$ make test
The main build targets are `serve`, `lint`, `build`, `test`, and `check`. The
latter is a meta-target that basically runs `lint`, `build`, and `test`.
The `serve` target starts a node-based web server, which we will refer to as the *dev server*. You'll need to start that server for running the examples and the tests in a browser. More information on that further down.
Other targets include `apidoc` and `ci`. The latter is the target used on Travis CI. See OpenLayers's [Travis configuration file](https://github.com/openlayers/openlayers/blob/master/.travis.yml).
## Running the `check` target
The `check` target is to be run before pushing code to GitHub and opening pull
requests. Branches that don't pass `check` won't pass the integration tests,
and have therefore no chance of being merged into `master`.
To run the `check` target:
$ make check
If you want to run the full suite of integration tests, see "Running the integration
tests" below.
## Running examples
To run the examples you first need to start the dev server:
$ make serve
$ npm run serve-examples
Then, just point your browser <http://localhost:3000/build/examples> in your browser. For example <http://localhost:3000/build/examples/side-by-side.html>.
Run examples against the `ol.js` standalone build:
The examples can also be run against the `ol.js` standalone build, just like
the examples [hosted](https://openlayers.org/en/master/examples/) on GitHub.
Start by executing the `host-examples` build target:
$ make host-examples
After running `host-examples` you can now open the examples index page in the browser: <http://localhost:3000/build/hosted/master/examples/>. (This assumes that you still have the dev server running.)
Append `?mode=raw` to make the example work in full debug mode. In raw mode the OpenLayers and Closure Library scripts are loaded individually by the Closure Library's `base.js` script (which the example page loads and executes before any other script).
Then, load <http://localhost:8080/> in your browser.
## Running tests
To run the tests in a browser start the dev server (`make serve`) and open <http://localhost:3000/test/index.html> in the browser.
To run the tests once:
To run the tests on the console (headless testing with PhantomJS) use the `test` target:
$ npm test
$ make test
To run the tests continuously during development:
See also the test-specific [README](../master/test/README.md).
## Running the integration tests
When you submit a pull request the [Travis continuous integration
server](https://travis-ci.org/) will run a full suite of tests, including
building all versions of the library and checking that all of the examples
work. You will receive an email with the results, and the status will be
displayed in the pull request.
To run the full suite of integration tests use the `ci` target:
$ make ci
Running the full suite of integration tests currently takes 5-10 minutes.

### Use of the `goog` namespace in examples
Short story: the OpenLayers examples should not use the `goog` namespace, except
for `goog.require`.
Longer story: we want that the OpenLayers examples work in multiple modes, with the
standalone lib (which has implications of the symbols and properties we
export), and compiled together with the OpenLayers library.
Compiling the examples together with the library makes it mandatory to declare dependencies with `goog.require` statements.
[OpenLayers](https://openlayers.org/) is a high-performance, feature-packed library for creating interactive maps on the web. It can display map tiles, vector data and markers loaded from any source on any web page. OpenLayers has been developed to further the use of geographic information of all kinds. It is completely free, Open Source JavaScript, released under the 2-clause BSD License (also known as the FreeBSD).
## Getting Started
Use one of the following methods to use OpenLayers in your project:
Install the [`ol` package](https://www.npmjs.com/package/ol):
* For use with webpack, Rollup, Browserify, or other module bundlers, install the [`ol` package](https://www.npmjs.com/package/ol):
```
npm install ol
```
```
npm install ol
```
* If you just want to add a `<script>` tag to test things out, you can link directly to one of the full builds from [cdnjs](https://cdnjs.com/libraries/openlayers) (not recommended for production)
Import just what you need for your application:
* For use with Closure Library (rare), install the [`openlayers` package](https://npmjs.com/package/openlayers) and read the [tutorial](http://openlayers.org/en/latest/doc/tutorials/closure.html).
See the following examples for more detail on bundling OpenLayers with your application:
* Using [Rollup](https://github.com/openlayers/ol-rollup)
* Using [Webpack](https://github.com/openlayers/ol-webpack)
* Using [Parcel](https://github.com/openlayers/ol-parcel)
* Using [Browserify](https://github.com/openlayers/ol-browserify)
## TypeScript and VS Code IntelliSense support
The `ol` package contains a `src/` folder with JSDoc annotated sources. TypeScript can get type definitions from these sources with a `tsconfig.json` like this:
```js
{
"compilerOptions":{
// Enable JavaScript support
"allowJs":true,
// Point to the JSDoc typed sources when using modules from the ol package
"baseUrl":"./",
"paths":{
"ol":["node_modules/ol/src"],
"ol/*":["node_modules/ol/src/*"]
}
},
"include":[
// Include JavaScript files from the ol package
"node_modules/ol/**/*.js"
]

##### Removal of the deprecated "inherits" function
The `inherits` function that was used to inherit the prototype methods from one constructor into another has been removed.
The standard ECMAScript classes should be used instead.
##### New internal tile coordinates
Previously, the internal tile coordinates used in the library had an unusual row order – the origin of the tile coordinate system was at the top left as expected, but the rows increased upwards. This meant that all tile coordinates within a tile grid's extent had negative `y` values.
Now, the internal tile coordinates used in the library have the same row order as standard (e.g. XYZ) tile coordinates. The origin is at the top left (as before), and rows or `y` values increase downward. So the top left tile of a tile grid is now `0, 0`, whereas it was `0, -1` before.
```
x, y values for tile coordinates
origin
*__________________________
| | | |
| 0, 0 | 1, 0 | 2, 0 |
|________|________|________|
| | | |
| 0, 1 | 1, 1 | 2, 1 |
|________|________|________|
| | | |
| 0, 2 | 1, 2 | 2, 2 |
|________|________|________|
```
This change should only affect you if you were using a custom `tileLoadFunction` or `tileUrlFunction`. For example, if you used to have a `tileUrlFunction` that looked like this:
```js
// before
functiontileUrlFunction(tileCoord){
constz=tileCoord[0];
constx=tileCoord[1];
consty=-tileCoord[2]-1;
// do something with z, x, y
}
```
You would now do something like this:
```js
// after
functiontileUrlFunction(tileCoord){
constz=tileCoord[0];
constx=tileCoord[1];
consty=tileCoord[2];
// do something with z, x, y
}
```
In addition (this should be exceedingly rare), if you previously created a `ol/tilegrid/WMTS` by hand and you were providing an array of `sizes`, you no longer have to provide a negative height if your tile origin is the top-left corner (the common case). On the other hand, if you are providing a custom array of `sizes` and your origin is the bottom of the grid (this is uncommon), your height values must now be negative.
##### Removal of the "vector" render mode for vector tile layers
If you were previously using `VectorTile` layers with `renderMode: 'vector'`, you have to remove this configuration option. That mode was removed. `'hybrid'` (default) and `'image'` are still available.
##### New `prerender` and `postrender` layer events replace old `precompose`, `render` and `postcompose` events
If you were previously registering for `precompose` and `postcompose` events, you should now register for `prerender` and `postrender` events on layers. Instead of the previous `render` event, you should now listen for `postrender`. Layers are no longer composed to a single Canvas element. Instead, they are added to the map viewport as individual elements.
##### New `getVectorContext` function provides access to the immediate vector rendering API
Previously, render events included a `vectorContext` property that allowed you to render features or geometries directly to the map. This is still possible, but you now have to explicitly create a vector context with the `getVectorContext` function. This change makes the immediate rendering API an explicit dependency if your application uses it. If you don't use this API, your application bundle will not include the vector rendering modules (as it did before).
Here is an abbreviated example of how to use the `getVectorContext` function:
```js
import{getVectorContext}from'ol/render';
// construct your map and layers as usual
layer.on('postrender',function(event){
constvectorContext=getVectorContext(event);
// use any of the drawing methods on the vector context
});
```
##### Layers can only be added to a single map
Previously, it was possible to render a single layer in two maps. Now, each layer can only belong to a single map (in the same way that a single DOM element can only have one parent).
##### The `OverviewMap` requires a list of layers.
Due to the constraint above (layers can only be added to a single map), the overview map needs to be constructed with a list of layers.
##### The `ol/Graticule` has been replaced by `ol/layer/Graticule`
Previously, a graticule was not a layer. Now it is. See the graticule example for details on how to add a graticule layer to your map.
##### Drop of support for the experimental WebGL renderer
The WebGL map and layers renderers are gone, replaced by a `WebGLHelper` function that provides a lightweight,
low-level access to the WebGL API. This is implemented in a new `WebGLPointsLayer` which does simple rendering of large number
of points with custom shaders.
This is now used in the `Heatmap` layer.
The removed classes and components are:
*`WebGLMap` and `WebGLMapRenderer`
*`WebGLLayerRenderer`
*`WebGLImageLayer` and `WebGLImageLayerRenderer`
*`WebGLTileLayer` and `WebGLTileLayerRenderer`
*`WebGLVectorLayer` and `WebGLVectorLayerRenderer`
*`WebGLReplay` and derived classes, along with associated shaders
*`WebGLReplayGroup`
*`WebGLImmediateRenderer`
*`WebGLMap`
* The shader build process using `mustache` and the `Makefile` at the root
##### Removal of the AtlasManager
Following the removal of the experimental WebGL renderer, the AtlasManager has been removed as well. The atlas was only used by this renderer.
The non API `getChecksum` functions of the style is also removed.
#### Other changes
##### Always load tiles while animating or interacting
`ol/PluggableMap` and subclasses no longer support the `loadTilesWhileAnimating` and `loadTilesWhileInteracting` options. These options were used to enable tile loading during animations and interactions. With the new DOM composition render strategy, it is no longer necessary to postpone tile loading until after animations or interactions.
### v5.3.0
#### The `getUid` function returns string
The `getUid` function from the `ol/util` module now returns a string instead of a number.
#### Attributions are not collapsible for `ol/source/OSM`
When a map contains a layer from a `ol/source/OSM` source, the `ol/control/Attribution` control will be shown with the `collapsible: false` behavior.
To get the previous behavior, configure the `ol/control/Attribution` control with `collapsible: true`.
### v5.2.0
#### Removal of the `snapToPixel` option for `ol/style/Image` subclasses
The `snapToPixel` option has been removed, and the `getSnapToPixel` and `setSnapToPixel` methods are deprecated.
The renderer now snaps to integer pixels when no interaction or animation is running to get crisp rendering. During interaction or animation, it does not snap to integer pixels to avoid jitter.
When rendering with the Immediate API, symbols will no longer be snapped to integer pixels. To get crisp images, set `context.imageSmoothingEnabled = false` before rendering with the Immediate API, and `context.imageSmoothingEnabled = true` afterwards.
### v5.1.0
#### Geometry constructor and `setCoordinates` no longer accept `null` coordinates
Geometries (`ol/geom/*`) now need to be constructed with valid coordinates (center for `ol/geom/Circle`) as first constructor argument. The same applies to the `setCoordinates()` (`setCenter()` for `ol/geom/Circle`) method.
### v5.0.0
#### Renamed `ol/source/TileUTFGrid` to `ol/source/UTFGrid`
The module name is now `ol/source/UTFGrid` (`ol.source.UTFGrid` in the full build).
#### Renaming of the `defaultDataProjection` in the options and property of the `ol/format/Feature` class and its subclasses
The `defaultDataProjection` option is now named `dataProjection`. The protected property available on the class is also renamed.
#### `transition` option of `ol/source/VectorTile` is ignored
The `transition` option to get an opacity transition to fade in tiles has been disabled for `ol/source/VectorTile`. Vector tiles are now always rendered without an opacity transition.
#### `ol/style/Fill` with `CanvasGradient` or `CanvasPattern`
The origin for gradients and patterns has changed from the top-left corner of the extent of the geometry being filled to 512 css pixel increments from map coordinate `[0, 0]`. This allows repeat patterns to be aligned properly with vector tiles. For seamless repeat patterns, width and height of the pattern image must be a factor of two (2, 4, 8, ..., 512).
#### Removal of the renderer option for maps
The `renderer` option has been removed from the `Map` constructor. The purpose of this change is to avoid bundling code in your application that you do not need. Previously, code for both the Canvas and WebGL renderers was included in all applications - even though most people only use one renderer. The `Map` constructor now gives you a Canvas (2D) based renderer. If you want to try the WebGL renderer, you can import the constructor from `ol/WebGLMap`.

```js
importMapfrom'ol/Map';
constcanvasMap=newMap({
renderer:['canvas']
// other options...

The main theme of the v5.0.0 release is an improved developer/user experience with OpenLayers. Toward this end, we have reworked the library as a set of ES Modules, completely removing any dependency on the Closure Compiler, and improving compatibility with mainstream module bundlers.
See the [hosted examples](https://openlayers.org/en/latest/examples/), [API docs](https://openlayers.org/en/latest/apidoc/), and [bundle tutorial](https://openlayers.org/en/latest/doc/tutorials/bundle.html) for the new syntax, but basic usage looks like this:

import{Map,View}from'ol';
importTileLayerfrom'ol/layer/Tile';
importOSMfrom'ol/source/OSM';
constmap=newMap({

newTileLayer({
source:newOSM()
})
],
view:newView({

renderer:['canvas']
// other options...
});
constwebglMap=newMap({
renderer:['webgl']
// other options...
});
```
New code:
```js
importMapfrom'ol/Map';
importWebGLMapfrom'ol/WebGLMap';
constcanvasMap=newMap({
// options...
});
constwebglMap=newWebGLMap({
// options...
});
```
#### Removal of ol.FeatureStyleFunction
The signature of the vector style function passed to the feature has changed. The function now always takes the `feature` and the `resolution` as arguments, the `feature` is no longer bound to `this`.
Old code:
```js
feature.setStyle(function(resolution){
vartext=this.get('name');
...
});
```
New code:
```js
feature.setStyle(function(feature,resolution){
vartext=feature.get('name');
...
});
```
#### Changed behavior of the `Draw` interaction
For better drawing experience, two changes were made to the behavior of the Draw interaction:
1. On long press, the current vertex can be dragged to its desired position.
2. On touch move (e.g. when panning the map on a mobile device), no draw cursor is shown, and the geometry being drawn is not updated. But because of 1., the draw cursor will appear on long press. Mouse moves are not affected by this change.
#### Changes in proj4 integration
Because relying on a globally available proj4 is not practical with ES modules, we have made a change to the way we integrate proj4:
* The `setProj4()` function from the `ol/proj` module was removed.
* A new `ol/proj/proj4` module with a `register()` function was added. Regardless of whether the application imports `proj4` or uses a global `proj4`, this function needs to be called with the proj4 instance as argument whenever projection definitions were added to proj4's registry with (`proj4.defs`).
It is also recommended to no longer use a global `proj4`. Instead,
npm install proj4
and import it:
```js
importproj4from'proj4';
```
Applications can be updated by importing the `register` function from the `ol/proj/proj4` module
```js
import{register}from'ol/proj/proj4'
```
and calling it before using projections, and any time the proj4 registry was changed by `proj4.defs()` calls:
```js
register(proj4);
```
#### Removal of logos
The map and sources no longer accept a `logo` option. Instead, if you wish to append a logo to your map, add the desired markup directly in your HTML. In addition, you can use the `attributions` property of a source to display arbitrary markup per-source with the attribution control.
#### Replacement of `ol/Sphere` constructor with `ol/sphere` functions
The `ol/Sphere` constructor has been removed. If you were using the `getGeodesicArea` method, use the `getArea` function instead. If you were using the `haversineDistance` method, use the `getDistance` function instead.
The optional this (i.e. opt_this) arguments were removed from the following methods. Please use closures, the es6 arrow function or the bind method to achieve this effect (Bind is explained here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind).
#### `Map#forEachLayerAtPixel` parameters have changed
If you are using the layer filter, please note that you now have to pass in the layer filter via an `AtPixelOptions` object. If you are not using the layer filter the usage has not changed.
To bind a function to a this, please use the bind method of the function (See: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/bind).
This change is due to the introduction of the `hitTolerance` parameter which can be passed in via this `AtPixelOptions` object, too.

The v5.0.1 release helps reduce bundle sizes for bundlers that support the `"sideEffects": "false"`option in `package.json`, and fixes website documentation regarding cdn locations and debug build which has been replaced by source maps.
## Fixes
* [#8341](https://github.com/openlayers/openlayers/pull/8341) - Set sideEffects: false flag ([@ahocevar](https://github.com/ahocevar))
* [#8342](https://github.com/openlayers/openlayers/pull/8342) - Fix links and description in quickstart tutorial ([@ahocevar](https://github.com/ahocevar))
* [#8371](https://github.com/openlayers/openlayers/pull/8371) - Skip rendering when there is no replay group ([@ahocevar](https://github.com/ahocevar))
The 5.1 release adds a few new features a handful of fixes. You should be able to upgrade without any additional work. See the one note below regarding `null` geometry coordinates.
We're working toward type checking with TypeScript. This will complete our move away from using the Closure Compiler for type checking and compilation. We're excited about the improved experience for application developers and will highlight some of the benefit in upcoming releases.
### Upgrade Notes
#### Geometry constructor and `setCoordinates` no longer accept `null` coordinates
Geometries (`ol/geom/*`) now need to be constructed with valid coordinates (center for `ol/geom/Circle`) as first constructor argument. The same applies to the `setCoordinates()` (`setCenter() for `ol/geom/Circle`) method.

The 5.2 release adds a few new features a handful of fixes, including regressions that were reported after the 5.1 release. You should be able to upgrade without any additional work. See the one note below regarding `snapToPixel` on `ol/style/Image` and subclasses.
We're still working toward type checking with TypeScript. Until that is complete, we apologize for some flwas in the online API documentation. We're excited about the improved experience for application developers when the effort is finished, and will highlight some of the benefit in upcoming releases.
### Upgrade Notes
#### Removal of the `snapToPixel` option for `ol/style/Image` subclasses
The `snapToPixel` option has been removed, and the `getSnapToPixel` and `setSnapToPixel` methods are deprecated.
The renderer now snaps to integer pixels when no interaction or animation is running to get crisp rendering. During interaction or animation, it does not snap to integer pixels to avoid jitter.
When rendering with the Immediate API, symbols will no longer be snapped to integer pixels. To get crisp images, set `context.imageSmoothingEnabled = false` before rendering with the Immediate API, and `context.imageSmoothingEnabled = true` afterwards.

We're continuing to work toward more complete type checking with TypeScript –based on JSDoc annotations in the source. The 5.3 release includes a number of bug fixes related to the type checking effort. In addition the release comes with a handful of new features and improved API reference docs.
### Upgrade Notes
#### The `getUid` function returns string
The `getUid` function from the `ol/util` module now returns a string instead of a number.
#### Attributions are not collapsible for `ol/source/OSM`
When a map contains a layer from a `ol/source/OSM` source, the `ol/control/Attribution` control will be shown with the `collapsible: false` behavior.
To get the previous behavior, configure the `ol/control/Attribution` control with `collapsible: true`.

Note the value of the `@event` annotation. The text before the hash refers to the event class that the event belongs to, and the text after the hash is the type of the event.
To export event properties, they need to be defined in `externs/oli.js` (also see `readme.md` in `externs/`) and marked with an @api annotation:
```js
/** @interface */
oli.MapBrowserEvent;
/**
* @type {ol.Coordinate}
* @api
*/
oli.MapBrowserEvent.prototype.coordinate;
// ...
};
```
To document which events are fired by a class or method, the `@fires` annotation is used:
// "baseUrl": "./", /* Base directory to resolve non-absolute module names. */
// "paths": {}, /* A series of entries which re-map imports to lookup locations relative to the 'baseUrl'. */
// "rootDirs": [], /* List of root folders whose combined content represents the structure of the project at runtime. */

// "allowSyntheticDefaultImports": true, /* Allow default imports from modules with no default export. This does not affect code emit, just typechecking. */
This primer shows you how to put a simple map on a web page.
**For production, we strongly recommend bundling the application together with its dependencies, as explained in the [Building an OpenLayers Application](./tutorials/bundle.html) tutorial.**

Layers in OpenLayers are defined with a type (Image, Tile or Vector) which contains a source. The source is the protocol used to get the map tiles. You can consult the list of [available layer sources here](/en/{{latest}}/apidoc/ol.source.html)
Layers in OpenLayers are defined with a type (Image, Tile or Vector) which contains a source. The source is the protocol used to get the map tiles.
The next part of the `Map` object is the `View`. The view allows to specify the center, resolution, and rotation of the map. The simplest way to define a view is to define a center point and a zoom level. Note that zoom level 0 is zoomed out.
OpenLayers is a modular, high-performance, feature-packed library for displaying and interacting with maps and geospatial data.
The library comes with built-in support for a wide range of commercial and free image and vector tile sources, and the most popular open and proprietary vector data formats. With OpenLayers's map projection support, data can be in any projection.
## Public API
OpenLayers is available as [`ol` npm package](https://npmjs.com/package/ol), which provides all modules of the officially supported [API](../../apidoc).
## Renderers and Browser Support
By default, OpenLayers uses a performance optimized Canvas renderer.
OpenLayers runs on all modern browsers that support [HTML5](https://html.spec.whatwg.org/multipage/) and [ECMAScript 5](http://www.ecma-international.org/ecma-262/5.1/). This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, [polyfills](http://polyfill.io), the application bundle needs to be transpiled (e.g. using [Babel](https://babeljs.io)) and bundled with polyfills for `requestAnimationFrame`, `Element.prototype.classList` and `URL`.
The library is intended for use on both desktop/laptop and mobile devices, and supports pointer and touch interactions.
## Module and Naming Conventions
OpenLayers modules with CamelCase names provide classes as default exports, and may contain additional constants or functions as named exports:
```js
importMapfrom'ol/Map';
importViewfrom'ol/View';
```
Class hierarchies grouped by their parent are provided in a subfolder of the package, e.g. `layer/`.
For convenience, these are also available as named exports, e.g.
```js
import{Map,View}from'ol';
import{Tile,Vector}from'ol/layer';
```
In addition to these re-exported classes, modules with lowercase names also provide constants or functions as named exports:
title: Basic project setup using NPM and Browserify
layout: doc.hbs
---
# Introduction
When going beyond modifying existing examples you might be looking for a way to setup your own code with dependency management together with external dependencies like OpenLayers.
This tutorial serves as a suggested project setup using NPM and Browserify for the most basic needs. There are several other options, and in particular you might be interested in a more modern one (ES2015) [using Webpack with OpenLayers](https://gist.github.com/tschaub/79025aef325cd2837364400a105405b8).
## Initial steps
Create a new empty directory for your project and navigate to it by running `mkdir new-project && cd new-project`. Initialize your project using `npm init` and answer the questions asked.
Add OpenLayers as dependency to your application with `npm install --save ol`.
At this point you can ask NPM to add required development dependencies by running
We will be using `cssify` to include the css definitions required by OpenLayers in our bundle. `watchify`, `http-server` and `uglify-js` are used to monitor for changes and to build into a minified bundle. `babelify` and `babel-plugin-transform-es2015-modules-commonjs` are used to make the `ol` package, which was created using ES2015 modules, work with CommonJS.
## Application code and index.html
Place your application code in `index.js`. Here is a simple starting point:
You will also need an `ìndex.html` file that will use your bundle. Here is a simple example:
```html
<!DOCTYPE html>
<html>
<head>
<metacharset="utf-8">
<title>Using Browserify with OpenLayers</title>
<style>
#map{
width:400px;
height:250px;
}
</style>
</head>
<body>
<divid="map"></div>
<scriptsrc="bundle.js"></script>
</body>
</html>
```
## Creating a bundle
With simple scripts you can introduce the commands `npm run build` and `npm start` to manually build your bundle and watch for changes, respectively. Add the following to the script section in `package.json`:
Now to test your application open http://localhost:8080/ in your browser. `watchify` will update `bundle.js` whenever you change something. You simply need to reload the page in your browser to see the changes.
```
$ npm start
```
Note that `bundle.js` will contain your application code and all dependencies used in your application. From OpenLayers, it only contains the required components.
Modern JavaScript works best when using and authoring modules. The recommended way of using OpenLayers is installing the [`ol`](https://npmjs.com/package/ol) package. This tutorial walks you through setting up a simple dev environment, which requires [node](https://nodejs.org) for everything to work.
In this tutorial, we will be using [Parcel](https://parceljs.org) to bundle our application. There are several other options, some of which are linked from the [README](https://npmjs.com/package/ol).
## Initial steps
Create a new empty directory for your project and navigate to it by running `mkdir new-project && cd new-project`. Initialize your project with
npm init
This will create a `package.json` file in your working directory. Add OpenLayers as dependency to your application with
npm install ol
At this point you can ask NPM to add required development dependencies by running
npm install --save-dev parcel-bundler
## Application code and index.html
Place your application code in `index.js`. Here is a simple starting point:
```js
import'ol/ol.css';
import{Map,View}from'ol';
importTileLayerfrom'ol/layer/Tile';
importOSMfrom'ol/source/OSM';
constmap=newMap({
target:'map',
layers:[
newTileLayer({
source:newOSM()
})
],
view:newView({
center:[0,0],
zoom:0
})
});
```
You will also need an `index.html` file that will use your bundle. Here is a simple example:
```html
<!DOCTYPE html>
<html>
<head>
<metacharset="utf-8">
<title>Using Parcel with OpenLayers</title>
<style>
#map{
width:400px;
height:250px;
}
</style>
</head>
<body>
<divid="map"></div>
<scriptsrc="./index.js"></script>
</body>
</html>
```

With two additional lines in `package.json` you can introduce the commands `npm run build` and `npm start` to manually build your bundle and watch for changes, respectively. The final `package.json` with the two additional commands `"start"` and `"build"` should look like this:
```json
{
"name":"test",
"version":"1.0.0",
"description":"",
"main":"index.js",
"scripts":{
"test":"echo \"Error: no test specified\" && exit 1",
"start":"parcel index.html",
"build":"parcel build --public-url . index.html"
},
"author":"",
"license":"ISC"
}
```
That's it. Now to run your application, enter
npm start
in your console. To test your application, open http://localhost:1234/ in your browser. Whenever you change something, the page will reload automatically to show the result of your changes.
Note that a single JavaScript file with all your application code and all dependencies used in your application has been created. From the OpenLayers package, it only contains the required components.
To create a production bundle of your application, simply type
npm run build
and copy the `dist/` folder to your production server.

# Compiling Application with Closure Compiler
**Note**: When building an application with dependencies that are available as [npm](https://npmjs.com/) packages, it will probably be easier to use the [ol](https://npmjs.com/package/ol) package and follow the instructions there.
The OpenLayers code uses the Closure Library, and it is compiled with the
Closure Compiler. Using OpenLayers in an application does not require using
Closure. But using Closure in an OpenLayers application is possible. And this
is what this tutorial is about.
When you want to include OpenLayers as separate script without bundling with your application, follow the [Creating custom builds](./custom-builds.html) tutorial instead.
This tutorial will teach you how to set up an OpenLayers application based on
the [`closure-util`](https://github.com/openlayers/closure-util) node package,
which provides utilities for working with Closure. Using `closure-util` is one
way to use Closure in a web application, but there are others. This tutorial
just covers the "`closure-util`" way.
The `closure-util` documentation is available on the [`closure-util` readme
page](https://github.com/openlayers/closure-util/blob/master/readme.md). You
don't need to read the `closure-util` documentation to follow this tutorial,
but it's available in `closure-util`'s [readme
file](https://github.com/openlayers/closure-util/blob/master/readme.md) if you
need it.
Also, the sample application built in this tutorial is
[available](https://github.com/openlayers/openlayers-closure-application) on
GitHub.
## Advantages of using Closure
This tutorial will show you how to use the Closure Compiler to compile an
application and OpenLayers together. Compiling the application code together
with the OpenLayers code has a number of advantages.
First of all, it allows you to only "pay" for the OpenLayers code your
application uses, as the compiler will exclude the OpenLayers code that the
application doesn't use. And there is no need to write and maintain a list of
"exports", which is necessary when creating custom builds of OpenLayers.
Also, compiling the application and OpenLayers together allows using
OpenLayers functions and objects that are not part of the official OpenLayers
3 API. Using non-API functions and objects may be risky, but it is mitigated by
the fact that the compiler will complain if you use functions or objects
that are not in OpenLayers anymore.
## Setting up the Application
First, create a directory for the application. We will name that directory
`openlayers-closure-application` in this tutorial.
$ mkdir openlayers-closure-application
Now change to that directory:
$ cd openlayers-closure-application
Our application will be a `node` application, and the `openlayers` and
`closure-util` node packages will be downloaded from the node package registry
using the `npm` command line tool.
So we're going to create a `package.json` file for the application, which every
node application includes. This file basically includes metadata for the
application.
Create the application's `package.json` file:
$ npm init
You can pretty much use the default answers to the questions `npm init` asks
you.
Now install OpenLayers using:
$ npm install openlayers --save
The `--save` flag persists the `openlayers` dependency in the application's
`package.json` file. You can edit `package.json` to verify that the dependency
was added.
`closure-util` is a dependency of the `openlayers` package, so it should have
been installed with `openlayers`. Use the following to verify that
The core component of OpenLayers is the map (`ol.Map`). It is rendered to a `target` container (e.g. a `div` element on the web page that contains the map). All map properties can either be configured at construction time, or by using setter methods, e.g. `setTarget()`.
The core component of OpenLayers is the map (`ol/Map`). It is rendered to a `target` container (e.g. a `div` element on the web page that contains the map). All map properties can either be configured at construction time, or by using setter methods, e.g. `setTarget()`.
The markup below could be used to create a `<div>` that contains your map.
The script below constructs a map that is rendered in the `<div>` above, using the `map` id of the element as a selector.
```js
import Map from 'ol/Map';
var map = new Map({target: 'map'});
```
## View
`ol.Map` is not responsible for things like center, zoom level and projection of the map. Instead, these are properties of an `ol.View` instance.
The map is not responsible for things like center, zoom level and projection of the map. Instead, these are properties of a `ol/View` instance.
```js
map.setView(new ol.View({
center: [0, 0],
zoom: 2
}));
import View from 'ol/View';
map.setView(new View({
center: [0, 0],
zoom: 2
}));
```
An `ol.View` also has a `projection`. The projection determines the coordinate system of the `center` and the units for map resolution calculations. If not specified (like in the above snippet), the default projection is Spherical Mercator (EPSG:3857), with meters as map units.
A `View` also has a `projection`. The projection determines the coordinate system of the `center` and the units for map resolution calculations. If not specified (like in the above snippet), the default projection is Spherical Mercator (EPSG:3857), with meters as map units.
The `zoom` option is a convenient way to specify the map resolution. The available zoom levels are determined by `maxZoom` (default: 28), `zoomFactor` (default: 2) and `maxResolution` (default is calculated in such a way that the projection's validity extent fits in a 256x256 pixel tile). Starting at zoom level 0 with a resolution of `maxResolution` units per pixel, subsequent zoom levels are calculated by dividing the previous zoom level's resolution by `zoomFactor`, until zoom level `maxZoom` is reached.
## Source
To get remote data for a layer, OpenLayers uses `ol.source.Source` subclasses. These are available for free and commercial map tile services like OpenStreetMap or Bing, for OGC sources like WMS or WMTS, and for vector data in formats like GeoJSON or KML.
To get remote data for a layer, OpenLayers uses `ol/source/Source` subclasses. These are available for free and commercial map tile services like OpenStreetMap or Bing, for OGC sources like WMS or WMTS, and for vector data in formats like GeoJSON or KML.
```js
var osmSource = new ol.source.OSM();
import OSM from 'ol/source/OSM';
var osmSource = OSM();
```
## Layer
A layer is a visual representation of data from a `source`. OpenLayers has three basic types of layers: `ol.layer.Tile`, `ol.layer.Image` and `ol.layer.Vector`.
`ol.layer.Tile` is for layer sources that provide pre-rendered, tiled images in grids that are organized by zoom levels for specific resolutions.
A layer is a visual representation of data from a `source`. OpenLayers has four basic types of layers:
`ol.layer.Image` is for server rendered images that are available for arbitrary extents and resolutions.
`ol.layer.Vector` is for vector data that is rendered client-side.
* `ol/layer/Tile` - Renders sources that provide tiled images in grids that are organized by zoom levels for specific resolutions.
* `ol/layer/Image` - Renders sources that provide map images at arbitrary extents and resolutions.
* `ol/layer/Vector` - Renders vector data client-side.
* `ol/layer/VectorTile` - Renders data that is provided as vector tiles.
```js
var osmLayer = new ol.layer.Tile({source: osmSource});
map.addLayer(osmLayer);
import TileLayer from 'ol/layer/Tile';
var osmLayer = new TileLayer({source: osmSource});
map.addLayer(osmLayer);
```
## Putting it all together
The above snippets can be combined into a single script that renders a map with a single tile layer:
The above snippets can be conflated to a self contained map configuration with view and layers:
OpenLayers is a big library providing a lot of functionality. So it is unlikely that an application will need and use all the functionality OpenLayers provides. This is why creating application-specific OpenLayers builds, with just the functionality your application needs, is often a good idea.
An alternative to creating custom builds is to compile your application code together with OpenLayers. See the [Compiling Application with Closure Compiler](closure.html) tutorial for more information.
This particular tutorial explains how to create custom builds of OpenLayers.
## Requirements
OpenLayers's build tools use Node and Java, so you need to have Node and Java installed on your machine. You can run `node --version` and `java -version` to test that Node and Java are installed, respectively. See [developing guide](https://github.com/openlayers/openlayers/blob/master/DEVELOPING.md) for minimum version numbers required.
## Download OpenLayers
Obviously, creating a custom build requires the OpenLayers source and specific build scripts.
To get the OpenLayers source and the build scripts you can clone the openlayers [repository](https://github.com/openlayers/openlayers), or you can download one of the release archives. You can also download the `openlayers` Node package from the Node package registry, using NPM (the Node Package Manager). This is the method we are going to use in this tutorial.
Create a directory:
$ mkdir openlayers
Download the OpenLayers distribution using NPM:
$ npm install openlayers
This will download the latest stable version of OpenLayers, and install it under `node_modules`. You can list the content of `node_modules` to verify that it effectively contains a directory named "openlayers".
The Node packages onto which the `openlayers` package depends are installed under `node_modules/openlayers/node_modules`. That directory should, for example, include `closure-util`, which is the utility library OpenLayers uses for Closure.
You should now have everything you need to create custom builds of OpenLayers!
## Create a build configuration file
Creating a custom build requires writing a build configuration file. The format of build configuration files is JSON. Here is a simple example of a build configuration file:
```json
{
"exports":[
"ol.Map",
"ol.View",
"ol.control.defaults",
"ol.layer.Tile",
"ol.source.OSM"
],
"compile":{
"externs":[
"externs/bingmaps.js",
"externs/cartodb.js",
"externs/closure-compiler.js",
"externs/esrijson.js",
"externs/geojson.js",
"externs/oli.js",
"externs/olx.js",
"externs/proj4js.js",
"externs/tilejson.js",
"externs/topojson.js"
],
"extra_annotation_name":[
"api","observable"
],
"compilation_level":"ADVANCED",
"manage_closure_dependencies":true,
"rewrite_polyfills":false
}
}
```
Create a file named `ol-custom.json` with that content, and save it under the `node_modules/openlayers/build` directory. (You can save it to any location really.)
The most relevant part of this configuration object is the `"exports"` array. This array declares the functions/constructors you use in your JavaScript code. For example, the above configuration file is what you'd use for the following JavaScript code:
```js
varmap=newol.Map({
target:'map',
layers:[
newol.layer.Tile({
source:newol.source.OSM()
})
],
controls:ol.control.defaults({
attributionOptions:{
collapsible:false
}
}),
view:newol.View({
center:[0,0],
zoom:4
})
});
```
Note that this JavaScript code corresponds to OpenLayers's [`simple`](https://openlayers.org/en/master/examples/simple.html) example.
You are now ready to create your first OpenLayers build. Use the following command to create the build:
The build command may take some time, but it should end with an output in the console such as the following:
info ol Parsing dependencies
info ol Compiling 364 sources
The build command should have created an `ol-custom.js` file in the `node_modules/openlayers/build` directory. You can verify that the file was created. You can even open it in your editor if you're curious.
As a test, you can use the following HTML file to verify that your custom build works as expected:
Closure allows you to define constants that can be set at compile time. The OpenLayers code defines several such values.
Setting some of these to `false` means that the portions of the code relating to this setting become "dead", i.e. are never executed. As Closure Compiler's `ADVANCED` mode removes dead code, this makes the size of the advanced compiled file smaller.
You might have noticed that the build file you've just created is considerably smaller than the full build, but it can be reduced further. This is because both renderers and other optional code are included by default. We only need one renderer, and we do not use the optional code, so can exclude what we don't use by setting properties with `define`s. So add a define section to the config above:
```
"define": [
"ol.ENABLE_WEBGL=false",
"ol.ENABLE_PROJ4JS=false",
"ol.ENABLE_RASTER_REPROJECTION=false"
],
```
and re-run the build script. The build size should now be smaller.
### Externs
The Closure documentation explains that "externs" are for external names used in the code being compiled. The compiler includes externs for built-ins such as `document`. The `externs` directory of the OpenLayers code includes files for all those used in some part of the library. For example, if you use Bing Maps, you should include the Bing externs file in the `externs` section of the config file.
`oli.js` and `olx.js` are externs files for the OpenLayers API. For example `olx.js` includes extern definitions for OpenLayers's constructor options. `closure-compiler.js` fixes any issues that may arise with a specific compiler version. You should always use these three files as externs when creating custom builds.
### Other compiler options
There are a couple of other compiler options in the config file above. `manage_closure_dependencies` and `rewrite_polyfills` should always be used.
You can specify any of the other compiler options here as needed, such as the renaming reports, output manifest, or source maps. There is a full list of available options in [closure-util](https://github.com/openlayers/closure-util/blob/master/compiler-options.txt).
Note that `build.js` currently requires you to enter an output file and will write the output from the compiler to it; it does not use the `js_output_file` compiler option. If you specify this in the config file, there will be no compiler output, so `build.js`'s output file will be empty.
## A more complicated example
Now let's try a more complicated example: [`heatmaps-earthquakes`](https://openlayers.org/en/master/examples/heatmap-earthquakes.html). The build configuration file looks like this:
```json
{
"exports":[
"ol.layer.Heatmap",
"ol.source.Vector",
"ol.format.KML",
"ol.layer.Heatmap#getSource",
"ol.source.Vector#on",
"ol.source.Vector.Event#feature",
"ol.Feature#get",
"ol.Feature#set",
"ol.layer.Tile",
"ol.source.Stamen",
"ol.Map",
"ol.View",
"ol.layer.Heatmap#setRadius",
"ol.layer.Heatmap#setBlur"
],
"compile":{
"externs":[
"externs/bingmaps.js",
"externs/cartodb.js",
"externs/closure-compiler.js",
"externs/esrijson.js",
"externs/geojson.js",
"externs/olx.js",
"externs/oli.js",
"externs/proj4js.js",
"externs/tilejson.js",
"externs/topojson.js"
],
"define":[
"ol.ENABLE_WEBGL=false",
"ol.ENABLE_PROJ4JS=false",
"ol.ENABLE_RASTER_REPROJECTION=false"
],
"compilation_level":"ADVANCED",
"manage_closure_dependencies":true,
"rewrite_polyfills":false
}
}
```
The exports are given here in the order in which they occur in the `heatmaps-earthquakes` example's JavaScript code. In this example we not only use the `ol.` functions and constructors, but also `prototype` methods where the `ol` namespace is not directly used. In the code, we have for example `vector.getSource().on()`. This means we are using the `getSource` method of `layer.Heatmap` and the `on` method of `source.KML`, so this is what has to be exported. Similarly, `event.feature.get()` means we are using the `feature` property of `source.Vector.Event` and the `get` method of `Feature`. If any of these names are left out, the compile will complete successfully, but the missing names will be obfuscated and you will get a 'property undefined' error when you try and run the script.
## Maintaining the code
If you installed OpenLayers from the Node package, you can use `npm` to upgrade to the latest version. If you cloned the Github repo, simply pulling in the latest code may not be enough, as some of the packages used, for example, the compiler, may need upgrading too. Do this by using `npm install` rather than `npm update`.
## Conclusion
This tutorial should have given you the information you need to create custom builds, i.e. builds tailored to your application. See the [tasks readme](https://github.com/openlayers/openlayers/tree/master/tasks/readme.md) for more information on the build scripts and the properties you can use in the build configuration file.
With version 3, the OpenLayers web mapping library was fundamentally redesigned. The widely used version 2 dates from the early days of Javascript development, and was increasingly showing its age. So it has been rewritten from the ground up to use modern design patterns.
The initial release aims to support much of the functionality provided by version 2, with support for a wide range of commercial and free tile sources, and the most popular open-source vector data formats. As with version 2, data can be in any projection. The initial release also adds some additional functionality, such as the ability to easily rotate or animate maps.
It is also designed such that major new features, such as displaying 3D maps, or using WebGL to quickly display large vector data sets, can be added in later releases.
## Google Closure
OpenLayers was written in a way so it can be compiled with [__Closure Compiler__](https://developers.google.com/closure/compiler/). Its 'advanced' compilation mode offers a level of compression that exceeds anything else available.
## Public API
Using the advanced optimizations of the Closure Compiler means that properties and methods are renamed – `longMeaningfulName` might become `xB` – and so are effectively unusable in applications using the library. To be usable, they have to be explicitly `exported`. This means the exported names, those not renamed, effectively become the public API of the library. These __exportable__ properties and methods are marked in the source, and documented in the [API docs](../../apidoc). This is the officially supported API of the library. A build containing all these exportable names is known as a __full build__. A hosted version of this is available, which can be used by any application.
## Custom Builds
Unlike in, say, Node, where a module's exports are fixed in the source, with Closure Compiler, exports can be defined at compile time. This makes it easy to create builds that are customized to the needs of a particular site or application: a __custom build__ only exports those properties and methods needed by the site or application. As the full build is large, and will probably become larger as new features are added to the API, it's recommended that sites create a custom build for production software.
## Renderers and Browser Support
The library currently includes two renderers: Canvas and WebGL. Both of them support both raster data from tile/image servers, and vector data; WebGL however does not support labels. Clearly only those browsers that [support Canvas](http://caniuse.com/canvas) can use the Canvas renderer. Equally, the WebGL renderer can only be used on those devices and [browsers](http://caniuse.com/webgl) that support WebGL.
OpenLayers runs on all modern browsers that support [HTML5](https://html.spec.whatwg.org/multipage/) and [ECMAScript 5](http://www.ecma-international.org/ecma-262/5.1/). This includes Chrome, Firefox, Safari and Edge. For older browsers and platforms like Internet Explorer (down to version 9) and Android 4.x, [polyfills](http://polyfill.io) for `requestAnimationFrame` and `Element.prototype.classList` are required, and using the KML format requires a polyfill for `URL`.
The library is intended for use on both desktop/laptop and mobile devices.
## Objects and Naming Conventions
The top-level namespace is `ol` (basically, `var ol = {};`). Subdivisions of this are:
* further namespaces, such as `ol.layer`; these have a lower-case initial
* simple objects containing static properties and methods, such as `ol.easing`; these also have a lower-case initial
* types, which have an upper-case initial. These are mainly 'classes', which here means a constructor function with prototypal inheritance, such as `ol.Map` or `ol.layer.Vector` (the Vector class within the layer namespace). There are however other, simpler, types, such as `ol.Extent`, which is an array.
Class namespaces, such as `ol.layer` have a base class type with the same name, such as `ol.layer.Layer`. These are mainly abstract classes, from which the other subclasses inherit.
Source files are similarly organised, with a directory for each class namespace. Names are however all lower-case, for example, `ol/layer/vector.js`.
OpenLayers follows the convention that the names of private properties and methods, that is, those that are not part of the API, end in an underscore. In general, instance properties are private and accessed using accessors.

Alternatively, a custom target TileGrid can be constructed manually and set on the source instance using `ol/source/TileImage~setTileGridForProjection(projection, tilegrid)`.

### Resolution calculation
When determining source tiles to load, the ideal source resolution needs to be calculated.
The `ol.reproj.calculateSourceResolution(sourceProj, targetProj, targetCenter, targetResolution)` function calculates the ideal value in order to achieve pixel mapping as close as possible to 1:1 during reprojection, which is then used to select proper zoom level from the source.
The `ol/reproj~calculateSourceResolution(sourceProj, targetProj, targetCenter, targetResolution)` function calculates the ideal value in order to achieve pixel mapping as close as possible to 1:1 during reprojection, which is then used to select proper zoom level from the source.
It is, however, generally not practical to use the same source zoom level for the whole target zoom level -- different projections can have significantly different resolutions in different parts of the world (e.g. polar regions in EPSG:3857 vs EPSG:4326) and enforcing a single resolution for the whole zoom level would result in some tiles being scaled up/down, possibly requiring a huge number of source tiles to be loaded.
Therefore, the resolution mapping is calculated separately for each reprojected tile (in the middle of the tile extent).
