Creating New Application

Let's use Angular CLI to create a new application and call it ng-framework. You can use that application to test components before building and publishing them to NPM, or redistributing via other resources.

ng new ng-framework

For convenience purposes, you can change the "start" script to also launch the application in the browser. To do that, open the package.json file and append --open argument to the start command:

    "scripts": {
        "start": "ng serve --open"

Next, you need to install the ng-packagr library as a development dependency.

npm install ng-packagr --save-dev

At this point, the project setup is complete, and you are ready to start building reusable component libraries.
