This project is rework of sample by M. Gechev:

The Ivy library distribution format will no longer distribute a UMD bundle. In this repository you can find how to produce a UMD bundle for your use cases.

(which means NG >= 13 version)

Done as part of review of this particular problem: externals not working for Angular 13

If you are working on a topic of trimming down size of multiple Angular projects, without complexity of Webpack MF (so webpack specific feature stays hidden), this is a project for you:

• custom build step to extract some dependencies out of the bundle
• custom rollup config
• using that different assets together (the project uses one of many possible ways to do this)

Example size of the project specific assets (without externals):

Initial Chunk Files           | Names         | Raw Size | Estimated Transfer Size
polyfills.08f1e56677fe7568.js | polyfills     | 36.22 kB | 11.53 kB
main.8446b2f654044436.js      | main          |  6.69 kB | 2.28 kB
styles.32505c4787ba148c.css   | styles        |  3.43 kB | 1.05 kB
runtime.6a44049d9ab1c63f.js   | runtime       |  1.04 kB | 599 bytes
                              | Initial Total | 47.39 kB | 15.45 kB

In this order:

npm run build:rollup

(next your specific script):

npm serve

npm build

or event tests:

npm test

Run ng serve for a dev server. Navigate to http://localhost:4200/.

Run ng build to build the project. The build artifacts will be stored in the dist/ directory.

Run ng test to execute the unit tests via Karma.

Run ng e2e to execute the end-to-end tests via a platform of your choice. To use this command, you need to first add a package that implements end-to-end testing capabilities.
