How to create Angular NPM Package and Publish

To create an Angular NPM package, you can follow these steps:

  1. Create a new Angular project:

    ng new my-package

  1. Change the directory into your package:

        cd my-package

  1. Create a new library inside your package:

        ng generate library my-library

  1. This will create a new directory called projects/my-library that contains the code for your library.

  1. Inside the projects/my-library directory, create a new file called public-api.ts. This file will export all the public functionality of your library.

  1. Write your library code inside the projects/my-library/src/lib directory.

  1. Export your library code from public-api.ts. For example, if your library has a component called MyComponent, you would export it like this:

    export * from './lib/my-component/my-component.component';

  1. Build your library using the following command:

    ng build my-library

This will compile your library and create a dist folder containing the compiled code.

  1. Create a package.json file in the root of your project. This file should contain the metadata for your package, including its name, version, description, and dependencies.

  2. Create an account for Use the following command to authenticate.

    npm login

  1. Publish your package to NPM using the following command:

        npm publish dist/my-library

This will publish your package to the NPM registry, making it available for others to use.

That's it! You've created an Angular NPM package. You can now use this package in other Angular projects by installing it via NPM and importing its functionality into your code.
