This task publishes an existing tag to the npm registry. To publish a new release, create a commit that updates the version number in package.json (e.g. to "3.1.0"). Then create a tag, push to GitHub, and run the publish task. Assuming "openlayers" is the remote for the canonical repo, this would look like the following:
git tag -a v3.1.0 -m "3.1.0"
git push --tags openlayers
./tasks/publish.sh 3.1.0
The task creates a build for each of the `PROFILES` in `publish.sh` (these correspond to `.json` files in the `config` directory). Builds are generated in the `dist` directory. Our `package.json` specifies `dist/ol.js` as the "main" build. So when people use a module loader to `require('openlayers')`, they get the full build. It is also possible to load a debug build (e.g. `require('openlayers/dist/ol-debug')`), and we can publish additional builds by adding `config` files and updating `PROFILES` in `publish.sh`.
The `.npmignore` file determines what is *not* included in the package (note that `node_modules` are always ignored). So if additional items are added to `.gitignore` that should not be included in the npm package, they need to go in `.npmignore` as well (ideally, we don't need to generate anything else outside of the `build` directory that doesn't belong in the package).
I've contacted the maintainer of the https://www.npmjs.org/package/openlayers package to see if we can take over ownership. Until then, we can publish packages under the name 'ol'.
This allows other packages to depend on the ol3 package and get the build tools (devDependencies are not installed when they are transitive dependencies). The justification here is that the ol3 package becomes useful to other packages when you are able to run the build.js task. For this task to run all of its dependencies must be available.
The test.js task starts the development server and runs the tests in PhantomJS. As mentioned in the readme, when running the tests continuously during development, it is more convenient to start the dev server and visit the root of the test directory in your browser.
Later we can bring in Karma to drive PhantomJS and other browsers, but this simple "run once" task is useful for the CI job.
By default, all paths in the build config (e.g. externs) are assumed to be relative to the ol3 repo root. To make it so relative paths are resolved from a different directory, use the cwd option.
In addition, this change makes it so the `build.js` task can be run from another directory.
The closure-util package works on Node 0.8, 0.10, and 0.11 (as of this writing), but it requires an updated version of npm to install on Node 0.8. For the build to pass on Travis, we update npm before installing other dependencies. For others who are installing the openlayers package, nothing special is required for Node 0.10 and above. For users on Node 0.8, the openlayers package will only install with an updated version of npm. This can be installed with npm itself.
npm install -g npm # only needed on Node 0.8
Since async and htmlparser2 are used by the postinstall task, they need to be listed as dependencies. These will get installed when ol3 is a dependency of another project.
