This repo is the demo/seed for bunding an Angular application with Google Closure Compiler. It contains a minimal Hello World application with a single component.

The compressed (brotli) JS size for an Angular 7.2.13 Hello World app is 58.28kb.

See https://github.com/angular/angular/issues/8550 for more context.

Try it

First, install brotli, which is a more modern compression algorithm than gzip. It gives a 13% smaller JS file, no work required! The commands below use it, but you don't have to.

On Mac, brew install brotli.

$ yarn install
$ yarn run build
$ yarn run serve

Where does the size come from?

$ yarn run explore

Notes

Requires Node >= 6.x since the ngc tool (and its deps) are now shipped as ES6 as well.

Requires Java installed to run the Closure Compiler. We recommend installing http://zulu.org/download-dev/.
