If you are an Angular library author, looking for
user-friendly Angular Schematics API wrapper,
then you are in the perfect place.

``
npm install @ngx-ext/schematics-api @schematics/angular @angular-devkit/schematics
`

add-imports-to-root-module.rule.ts file:
`typescript
import { Rule, Tree } from '@angular-devkit/schematics';
import { RootModule } from '@ngx-ext/schematics';

export function addImportsToRootModule(): Rule {
return (tree: Tree) => {
const rootModule = RootModule.getInstance(tree, '@my/lib');
rootModule.addImport('MyLibModule.forRoot()');
rootModule.addImport('MyLibModule2.forRoot()');
rootModule.addExport('MyLibNestModule', '/nested');
return rootModule.applyAllChanges();
};
}
`

schematics/ng-add/index.ts:
`typescript
import { chain, Rule, SchematicContext, Tree } from '@angular-devkit/schematics';
import { addImportsToRootModule } from './add-imports-to-root-module.rule';
import { installDependencies } from './install-dependencies.rule';

export function ngAdd(_options: any): Rule {
return (_tree: Tree, _context: SchematicContext) => {
return chain([
installDependencies(),
addImportsToRootModule(),
]);
};
}
`

After firing ng add @my/lib in Angular project, proper import statements and declarations will be added to its root module.
Example simplified output:
`typescript
import { MyLibModule, MyLibModule2 } from '@my/lib';
import { MyLibNestedModule } from '@my/lib/nested';

@NgModule({
declarations: [/ no changes /],
imports: [
MyLibModule.forRoot(),
MyLibModule2.forRoot(),
MyLibNestedModule,
],
exports: [MyLibNestedModule],
providers: [/ no changes /],
bootstrap: [AppComponent],
})
export class AppModule { }
