The Rails asset pipeline, old and new
This is done through the Webpacker::DevServerProxy which is a rack middleware that is added by Webpacker.

Asset Pipeline JS Migration
Using Webpacker in Rails provides several advantages over the traditional asset pipeline. First, Webpacker uses JavaScript modules, which allows for better code organization and improved code reusability. Second, it offers modern frontend build tools, such as Babel and PostCSS, for transforming and compiling assets. Third, it provides faster build times and faster runtime performance through code splitting and lazy loading. Fourth, it offers better integration with JavaScript frameworks such as React, Vue, and Angular. Overall, Webpacker offers a more flexible and modern asset management solution for Rails applications. And while Webpacker is being retired, this initiative is to consolidate our code accordingly before moving our bundler to another solution.

Thank you Webpacker, Goodbye Webpacker
This article is replace Webpacker with Simpacker and webpack.

How to setup ruby on rails + Angular
in ruby on rails 7 what is the best way to properly install Angular because I can't find any documentation about it. The only tutorial that exists uses webpacker (https://github.com/rails/webpacker) but unfortunately it is no longer supported and no longer up to date in terms of security.

What is the pros and cons of using Rails asset pipeline vs. webpack to hold assets?
From the webpacker gem:
-
Webpacker can’t find application.js - fix or bypass completely?
Check this: https://github.com/rails/webpacker/issues/2825
-
Using Rails+ReactJS with Webpacker on VS Code?
instead of using webpacker you should move to esbuild or importmap. Webpacker has been retired a few months ago (cf https://github.com/rails/webpacker) There are videos explained how to set this up (e.g. for importmap https://learnetto.com/tutorials/how-to-use-react-with-rails-7

Moving from BS4 to BS5 in Rails 6, having unexpected results
Took me 2 days to find this bug report: https://github.com/rails/webpacker/issues/3188 (thanks again tagliala)

Webpacker 6 development continues as shakacode/shakapacker
But it's there in the webpacker README now, if anyone hasn't seen it. https://github.com/rails/webpacker
importmap-rails

The Rails asset pipeline, old and new
It is implemented as a thor task in lib/importmap/cmmands.rb

RubyJS-Vite
With importmaps (https://github.com/rails/importmap-rails) and Hotwire (https://hotwired.dev/), you write plain js and serve it.
Also packages are served via CDN. There is no tree shaking. Rails got rid of the whole bundling step.

Asset compilation taking ~ 12 mins
It worked, but JS changes were not coming through. Digging into the Importmap docs (see 'sweeping the cache', it monitors changes according to the setting config.importmap.cache_sweepers. So, by adding the locations where I have my JS files, I also got JS changes passed through.

Is the default importmap method unrealistic in the most popular real world use cases?
You can't use TypeScript, or anything that requires pre-compile, with importmap. answered issue

Ruby on Rails with React on Typescript using importmaps
Let's begin by installing the necessary dependencies. The first gem generates the importmap object, manages caching, and helps with library installations, among other things. I recommend reading the entire readme to become familiar with its capabilities. The second gem will be discussed later, it is used to compile JSX files. Gemfile

Pirep.io collects the unpublished, local knowledge on public, private, and unmapped airport that anyone can contribute to
Yeah, those were brand new right around the time I started this project a few years ago with Rails 7 (or was it 6.1?). I actually ended up removing them in favor of importmap-rails since I wanted as simple of a frontend as possible and I wasn't sure of relying on what was, at the time, a brand new way of doing frontend work. Things change so quickly in JS-land that I'm always hesitant to make something a dependency unless it has a strong track record of being continuously maintained.

A powerful search feature with what Rails provides out of the box
Also, installing StimulusReflex seems quite not easy for the moment: It seems there are some quirks along the way if you're using import-maps for managing javascript dependencies as I do. Embracing the Rails way at least prevents you from this sort of issue.
What are some alternatives?
shakapacker - Use Webpack to manage app-like JavaScript modules in Rails
jsbundling-rails - Bundle and transpile JavaScript in Rails with esbuild, rollup.js, or Webpack.
esbuild - An extremely fast bundler for the web
esbuild-rails - Esbuild Rails plugin
Asset Sync - Synchronises Assets between Rails and S3
esbuilder - Integrate esbuild into Rails
Sprockets
vite_ruby - ⚡️ Vite.js in Ruby, bringing joy to your JavaScript experience
turbo-rails - Use Turbo in your Ruby on Rails app
esbuild-live-reload
webpack - A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows for loading parts of the application on demand. Through "loaders", modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.
