Description: manage modern JavaScript in Rails
Import maps let you import JavaScript modules using logical names that map to
versioned/digested files – directly from the browser. So you can build modern
JavaScript applications using JavaScript libraries made for ES modules (ESM)
without the need for transpiling or bundling. This frees you from needing
Webpack, Yarn, npm, or any other part of the JavaScript toolchain. All you need
is the asset pipeline that's already included in Rails. With this approach
you'll ship many small JavaScript files instead of one big JavaScript file.
Thanks to HTTP/2 that no longer carries a material performance penalty during
the initial transport, and in fact offers substantial benefits over the long
run due to better caching dynamics. Whereas before any change to any JavaScript
file included in your big bundle would invalidate the cache for the whole
bundle, now only the cache for that single file is invalidated. Import maps are
supported natively in all major, modern browsers. If you need to work with
legacy browsers without native support, you can explore using the shim
available.
I intend on maintaining this under the Debian Ruby umbrella.
Thanks,
