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 JS size for an Angular 6.0.0 Hello World app is 57.15kb.

See angular/angular#8550 for more context.

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

$ yarn run explore

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/.
