Useful utilities for Angular Schematics

Schematics

Schematics are generators that transform an existing filesystem.
They can create files, refactor existing files, or move files around.

More info

Getting started

This library provide a large set of utilities that can be used while developing a schematic for Angular.

👉 Learn about it on the 📚 docs site.

Example

export default (options: MySchematicOptions): Rule =>
  schematic('my-schematic', [
    modifyJsonFile('tsconfig.json', ['compilerOptions', 'strict'], true),
    rule((tree, context): Rule => {
      ... return renameFile('old-file', 'new-file');
      ... return chain([]);
      ... return noop();
    }),

    workspace()
      .spawn('ng', ['add', '@angular/material', '--skip-confirmation'])
      .addPackageJsonDevDependencies(['eslint'])
      .packageInstallTask()
      .logInfo('Doing some cool stuff')
      .isAngularVersion('<= 11', (): Rule => {
        ...
      })
      .toRule(),

    application(options.project)
      .deployFiles(options)
      .addProviderToBootstrapApplication('__MAIN__', 'provideAnimations()', '@angular/platform-browser/animations'),
      .addImportToFile('__SRC__/file.ts', 'environment', './environments/environment')
      .deleteFiles(['karma.conf.js'])
      .rule(({ project }: ChainableApplicationContext) => {
        return createOrUpdateFile(project.pathFromRoot('README.md'), project.name);
      })
      .toRule(),

    library(options.project)
      .downloadFile('https://my-cdn.com/icons/icon.png', '__SRC__/assets/icons/icon.png')
      .toRule(),

    runAtEnd(logAction('Have a look at `./package.json` file and make modifications as needed.'))

  ], options);
