new NgcEsbuild({
  main: 'src/main.ts',
  outpath: 'dist/es2',
  minify: true,
  open: false,

Documentation 📄

WARNING!
The package is in the early alpha version!

This package is based on the esbuild.
Esbuild is an extremely fast builder for web projects, written in GoLang.
I extended esbuild with its plugin API and created some internal plugins.
These plugins process .ts files, handle dependency injectors, unpack styles, etc.

Limitations

build part	supported	notice
templateUrl	Yes	move to import statement
styleUrls	Partial	only one styleUrl
angular.json:styles	Yes	move to main.css
angular.json:scripts	Yes	move to vendor.js
dependency injection	Partial	constructor must contain only injectable objects
loadChildren	Yes	move to a separated file
assets	Yes	copy to the output folder
scss :root	No	angular pseudo-selectors are not supported yet
less	No	less stylesheets are not supported yet
style encapsulation	No	work in progress
