Angular2+ Library Starter Kit

npm Version Build Status

Angular2+ Library Starter Kit.

What you get out of the box

A NPM library such as:

Which can be installed and imported as easy as npm install your-library-name and import { MyModule } from 'your-library-name'

A demo page such as:


  • Based on angular-cli
  • Compatibility with Angular CLI, Webpack and SystemJS (built with ng-packgr)
  • Demo project (watch your library result as you develop)
  • Angular tests & E2E tests
  • Travis CI autodeploy to NPM
  • Travis CI demo autodeploy to GitHub Pages

Getting started

git clone
npm install
npm start

Write your package metadata

Make this library yours. Edit package.json, .angular-cli.json and .travis.yml and replace all ocurrences of angular-library-starter-kit with your-module-name (make sure it doesn't exist on NPM yet).

For the package.json -> build-gh-pages make sure to change zurfyx with your GitHub name or organization name. It will be used to later deploy your demo page onto GitHub pages.

Same thing has to be done with .travis.yml -> after_sucess. We'll get into secure tokens in Setting up Continuous Integration.

Write your module

Edit src/ with your library contents. The current taggify.module.ts, taggify.pipe.ts, taggify.pipe.spec.ts and index.ts should be edited with your module stuff.

Everything you want the target users to be able to import directly should be added into index.ts. Remember that shared components or pipes should be written both into declarations and exports when defining your module.

Write your module demo

Edit example/app files just like if it was a normal angular-cli site. You might want to make use of import { YourModule } from '../../src' at some point to proof that your library works as expected.

Test your module

You can write both e2e test over your demo site, and unit tests on either the src and example/app.

You might want to check e2e/app.e2e-spec.ts and src/taggify.pipe.spec.ts as examples.

Upload your module onto NPM

This process can be done automatically with Travis CI. See Autodeploy to NPM.

npm run build

Browser into the dist/ folder, where the result is stored and publish it into NPM.

cd dist
npm publish

Your module should now be up and ready!

Folder structure

For the most part, the folder structure is identical to angular-cli's one.

|- example/app Your demo application (GH pages)
|- src All your library source code, which will get packaged and distributed.

Setting up Continuous Integration

While you can use any CI of your choice, Travis CI is already set up to do the demo deployment onto GitHub Pages and library into NPM for you.

Read over Write your package metadata first, if you haven't already.

First of all, activate Travis on your GitHub repository. You can do so on your Travis profile.

Autodeploy to GitHub Pages

In order to deploy to GitHub Pages we need a GitHub token of yours.

Generate a token here. Scopes: [x] repo.

Encrypt the token. On your source code folder run the following command:

travis encrypt GH_TOKEN=your_token_here

The result should be copy-pasted into env -> global -> secure.

Autodeploy to NPM

A similar thing to GitHub Pages can be done with NPM.

Generate a token with npm token create.

Encrypt the token. On your source code folder run the following command:

travis encrypt your_token_here

The result should be copy-pasted into deploy -> api_key -> secure.
