To create a new component, run npm run generate <component-name> to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module <name>.
Run ng generate library library-name to create a new library project.
The public-api.ts file is going to be the entry point to your library. This is where you’ll export all the files that you want the user to be able to use. So any files that you export from this file will be accessible to the users who install your library.
After creating a new component, you'll need to add its corresponding exports in the public-api.ts file.
Run ng build angular-lib-boilerplate to build the project. The build artifacts will be stored in the dist/ directory.
Note: You can change the default angular-lib-boilerplate name in the angular.json file
Once the build process is done, you'll find a dist folder in your root directory.
Now that we have this build ready, we can use it in our project just like we would use any other third-party library.
cd .\dist\initial-component //WILL TAKE YOU INSIDE YOUR DIST FOLDER
