## What it is
A collection of community Angular CLI builders that extend the Angular build facade with custom webpack/esbuild configuration and Jest unit testing support. Packages ship schematics for automated setup and version-aligned migrations.

## Use cases
- customize webpack config in an Angular CLI project without ejecting
- run Jest unit tests in Angular instead of Karma
- extend the Angular dev server with custom webpack-dev-server options
- customize esbuild options in modern Angular builds
- migrate Angular builders between major versions automatically

## When to choose
- you need build customization beyond what angular.json options allow
- your team prefers Jest over the default Karma test runner
- you want drop-in builders with automated ng add/ng update migrations

## When to avoid
- your project builds fine with default Angular CLI configuration
- you use a non-Angular bundler setup like Nx with its own executors
- you need builders for an Angular major version not yet supported

## Facets
- artifact type: library
- maturity: active
- function: build-tool, testing, developer-tools
- domain: web-development, frontend, developer-tools, testing
- platform: cli, cross-platform
