Refactor Frontend + Asset code
- Use Laravel's Filesystem component for asset IO, meaning theoretically
assets should be storable on S3 etc.
- More reliable checking for asset recompilation when debug mode is on,
so you don't have to constantly delete the compiled assets to force
a recompile. Should also fix issues with locale JS files being
recompiled with the same name and cached.
- Remove JavaScript minification, because it will be done by Webpack
(exception is for the TextFormatter JS).
- Add support for JS sourcemaps.
- Separate frontend view and assets completely. This is an important
distinction because frontend assets are compiled independent of a
request, whereas putting together a view depends on a request.
- Bind frontend view/asset factory instances to the container (in
service providers) rather than subclassing. Asset and content
populators can be added to these factories – these are simply objects
that populate the asset compilers or the view with information.
- Add RouteHandlerFactory functions that make it easy to hook up a
frontend controller with a frontend instance ± some content.
- Remove the need for "nojs"
- Fix cache:clear command
- Recompile assets when settings/enabled extensions change
* Replace gulp with webpack and npm scripts for JS compilation
* Set up Travis CI to commit compiled JS
* Restructure `js` directory; only one instance of npm, forum/admin are "submodules"
* Refactor JS initializers into Application subclasses
* Maintain partial compatibility API (importing from absolute paths) for extensions
* Remove minification responsibility from PHP asset compiler
* Restructure `less` directory
Symfony's component relies on PHP's native session functionality, which
is not ideal. It automatically sets its own cookie headers, resulting in
this issue: https://github.com/flarum/core/issues/1084#issuecomment-364569953
The Illuminate component is more powerful and has a simpler API for
extension with other drivers and such, and fits in nicely with other
components we use (the majority of which are from Illuminate).
* Add Custom Footer HTML
Straight copy from Custom Header HTML
* Move Custom Footer HTML to exactly before `</body>` tag.
* Fix invalid class name
* Append CustomFooterHTML when preparing the view.
* Some consistency in placing the variable
