A generator used to scaffold Angular modules to be published to npm.


  • :package: Quickly create npm packages that contain Angular modules
  • :gem: Publish with or without scope
  • :postbox: Use official or your own registry
  • :open_file_folder: Clean project structure
  • :broken_heart: Seperated Angular development environment
  • :no_entry: Uses strictest typescript setup possible
  • :de: Made in Germany


This generator can be used to create npm packages that contain Angular modules, services, components and so on.

It is a biased set of conventions and configurations that you should bend to your needs.

It seperates and includes your module to an Angular CLI installation so that you can develop and test your module in the target environment before publishing.

Quick Start

Setup a new npm angular project

npm i -g yo # install yeoman if you have not already
npm i -g npm-angular # install npm-angular
yo npm-angular # start npm-angular
ng new your-angular --skip-git --directory ./angular/ # add angular

See Mandatory Angular Setup after successful installation.

Start package development

tsc -w

Start Angular with your integrated module

cd ./angular
ng serve
ng test

Mandatory Angular configuration


"paths": {
  "@your-module-name": ["./../src/index.ts"], // convenience setup for angular project
  "@angular/*": ["./node_modules/@angular/*"]  // only use local angular to avoid circular dependecy


To not have to setup and maintain another seperate test environment npm-angular uses Angular's existing setup in ./angular/

To make this work tests created for your npm package need some extra setup.


Reset and initialize Angular's test environment with every new TestBed.

import { TestBed, async } from '@angular/core/testing';
import { TestedComponent } from './tested.component';
import { BrowserDynamicTestingModule, platformBrowserDynamicTesting } from '@angular/platform-browser-dynamic/testing'; // new

describe('TestedComponent', () => {

  beforeEach(async(() => {

    TestBed.resetTestEnvironment(); // new
    TestBed.initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting()); // new

      declarations: [


  it('should create TestedComponent', async(() => {
    const fixture = TestBed.createComponent(TestedComponent);
    const app = fixture.debugElement.componentInstance;



After installing Angular in ./angular/ you need to add an additional context to Angular's test.ts.

// Then we find all the tests.
const context = require.context('./', true, /\.spec\.ts$/);
const contextNpmAngular = require.context('./../../src/', true, /\.spec\.ts$/) // new;

// And load the modules.
contextNpmAngular.keys().map(contextNpmAngular); // new


Add npm-angular's folder to the Angular testing setup.

"include": [
  "../../src/**/*.spec.ts", //  new - ng test your module in ./angular

Project structure

|- src
    |- index.ts
    |- module-name
        |- module-name.module.ts
        |- components
        |- services
        |- directives
        |- ...
|- angular


Contains what will be published with the package.

In here you are free to create any structure of angular components as you wish. Initially it contains the packages main file index.ts and one module folder.


Contains an Angular project that imports your package module so that you can develop and test it in the Angular environment.

Styles and Templates in Components

When creating a new component, note that npm-angular will not publish or compile SCSS/CSS or HTML.

You need to add styles and templates inline.

import { Component, OnInit } from '@angular/core';

  selector: 'your-componente',
  template: `
    <p>YourComponent works</p>
  styles: [`
    p { color: paleturquoise };
export class YourComponent implements OnInit {
  constructor() { }
  ngOnInit() { }
