I use Parcel to bundle the assets. Be aware I use the version 2 which is still in beta version. I really like Parcel, but unfortunately version 1 is buggy with the setup I want…
Either if you started Parcel via docker-compose or NPM, it will look at two
files: src/assets/stylesheets/application.css
and src/assets/javascripts/application.js.
These files are the entrypoints and load the other CSS and JS files, which are
monitored by Parcel.
Each time Parcel detects a change in one of these files, it bundles the files
altogether and puts the bundled files under the public/dev_assets/ folder.
The files are finally loaded in the application by the layout
via the url_asset() function.
Please note you must never change directly the files under the public/dev_assets/
folder since they will be erased at the next build.
At each release, the assets are bundled and minified under the public/assets/
folder. The url_asset() view function is configured to serve this folder in
production.
