Openlayers classes use an underscore suffix convention to mark class
members as private. These are undocumented implementation details and
presumably unsafe for code outside the class to rely on.
Allowing javascript minimisation to change these names gives 5% bundle
size reduction to the library.
This makes it possible to pickup new examples and prevents compilation
errors when an example is removed. This is especially handy when switching
branches. Otherwise the dev server has to be restarted each time.
This updates ESLint and our shared eslint-config-openlayers to use Prettier. Most formatting changes were automatically applied with this:
npm run lint -- --fix
A few manual changes were required:
* In `examples/offscreen-canvas.js`, the `//eslint-disable-line` comment needed to be moved to the appropriate line to disable the error about the `'worker-loader!./offscreen-canvas.worker.js'` import.
* In `examples/webpack/exapmle-builder.js`, spaces could not be added after a couple `function`s for some reason. While editing this, I reworked `ExampleBuilder` to be a class.
* In `src/ol/format/WMSGetFeatureInfo.js`, the `// @ts-ignore` comment needed to be moved down one line so it applied to the `parsersNS` argument.
