## What it is
Broccoli is a fast, reliable asset pipeline for building browser applications, running on Node.js and backend-agnostic. Builds are defined in a Brocfile.js (or .ts) as trees of directories or plugin objects, supporting constant-time rebuilds.

## Use cases
- build frontend assets for a browser app
- set up an asset pipeline with incremental rebuilds
- compile and transform source trees with plugins
- define production vs development builds in a Brocfile
- serve and rebuild assets during development

## When to choose
- you need a fast, tree-based asset pipeline for a client-side app
- you want constant-time rebuilds during development
- you're working in the Ember.js ecosystem where Broccoli is standard

## When to avoid
- you're building a backend or Node server bundle
- you prefer modern bundlers like Vite, esbuild, or webpack
- you need a full-featured module bundler rather than an asset pipeline
