Feeling a need to create re-usable UI components for all of your projects or for all the projects across your organization? Here's a quick guide to creating such a library with angular and for angular apps and finally publish it to npm.
ng new <project-name> --createApplication=false.
--createApplication=false flag will provide an angular workspace without any app inside it.
ng g library <lib-name>
ng g application <app-name>
hello world component.
These are the steps to build and publish to npm manually. Based on your CI-CD tool you may automate them.
npm version patch or
npm version minor or
npm version major.
ng build <lib-name>.
cd dist/<lib-name> and run
npm publish. (offcourse, first you need to be logged in to npm).
encapsulation: ViewEncapsulation.None as suggested here is one of the common way to include global styles.
Since the theme.min.css is now a part of lib so the user can simple import this file from their node_modules folder. It's preferred to add this file in angular.json's
Similarly you can export global js and import it from node_modules into angular.json's
This is a bit tricky and need to follow specific guidelines.
I prefer copying them using cpx and then in the app copy them again from node_modules folder to
assets/* or any folder having similar path as it is there in lib code.
