The purpose of this repository is to consolidate all the community builders for Angular build facade.

Builders' and Angular major versions must match.

custom-esbuild, custom-webpack and jest ship Angular schematics, so both the initial setup and the move between majors are automated:

ng add @angular-builders/<package>     # set the builder up in your workspace
ng update @angular-builders/<package>  # move an existing project to a new major

ng update applies every migration between the version you have installed and the one you are moving to, so the builder's own migrations all run in one pass. Updating from version 17 or later is supported. Builder majors track Angular majors, so a project moving up several versions upgrades Angular first, and this command then brings the builder in line. Each package README documents what its schematics change for you and which changes they can only warn about. bazel and timestamp have no schematics, so those two are still configured by hand.

⚠️ Version alignment: The major version of @angular-builders/* packages must match the major version of @angular/core in your project. For example, Angular 19 requires @angular-builders/*@19.x, Angular 20 requires @angular-builders/*@20.x, etc. Using a mismatched version is the most common source of issues.
