## What it is
Webpack Encore is a JavaScript library providing a simple, powerful API on top of Webpack for bundling JavaScript, compiling and minifying CSS/JS assets, and managing frontend builds. It is developed by Symfony but usable in any application, and is now in low-maintenance mode with Symfony recommending migration to Symfony Reprise or AssetMapper.

## Use cases
- bundle javascript and css assets with a simple webpack api
- compile sass and less stylesheets in a web project
- set up react or vue with babel and webpack easily
- version and hash assets for cache busting
- enable hot module replacement during development
- split javascript code into async chunks
- minify javascript and css for production

## When to choose
- you have an existing Symfony app already built on Encore
- you want a simplified, opinionated wrapper around Webpack for asset compilation
- you need Sass, Less, PostCSS, TypeScript, React or Vue support with minimal config
- you want asset versioning, code splitting and HMR without hand-writing Webpack config

## When to avoid
- you are starting a new project - Symfony recommends AssetMapper or Symfony Reprise (Vite/Rsbuild) instead
- you need a bundler with active feature development, since Encore is in low-maintenance mode
- you want a no-build-step asset system - AssetMapper runs entirely in PHP
- your project does not use Node.js
