Key Components of Angular DevKit

Angular DevKit consists of several packages, mainly:

1. @angular-devkit/core

• A set of core utilities and abstractions for working with schematics, file systems, and logging.
• Provides a framework-independent API for building tools.

2. @angular-devkit/schematics

• Used for defining and running code transformations (like generating components, services, modules, etc.).
• Works with templates and rules to modify the file system.
• Example: ng generate component my-component uses schematics to create the component.

3. @angular-devkit/architect

• A task scheduling and execution tool.
• Powers ng build, ng serve, ng test, and ng lint.
• Allows customization and extension of Angular CLI commands.

4. @angular-devkit/build-angular

• Contains Webpack-based builders for compiling and serving Angular applications.
• Handles:
  • TypeScript compilation
  • Optimization
  • Differential loading
  • Asset processing
• Used when running ng build, ng serve, and similar commands.

5. @angular-devkit/build-webpack

• Provides a more generic Webpack-based build system.
• Can be used to extend or customize Webpack configurations.
