## What it is
Webpacker is a Ruby gem that integrates Webpack with Ruby on Rails applications to manage app-like JavaScript modules. It has been officially retired since Rails 7, with users directed to jsbundling-rails, importmap-rails, or the community-maintained Shakapacker fork.

## Use cases
- bundle JavaScript modules in a Rails app with Webpack
- manage app-like JavaScript assets in Rails
- integrate Webpack and Yarn into a Rails project
- migrate a legacy Rails app off Webpacker
- find the maintained successor to Webpacker

## When to choose
- maintaining an older Rails 5/6 application already built on Webpacker
- you need a stable, documented bridge between Rails and Webpack for legacy code

## When to avoid
- starting a new Rails 7+ project (use jsbundling-rails or importmap-rails)
- you want ongoing updates or new JavaScript library versions
- you need hot-module reloading or active development (use Shakapacker)

## Facets
- artifact type: library
- maturity: abandoned
- function: build-tool, developer-tools
- domain: web-development, frontend, developer-tools
- platform: ruby
- tags: webpack, rails, javascript-bundling, retired, shakapacker-successor, nodejs
