This is a super-hacky tool that processes JavaScript bundless before they are fed to Uglify.
Purify adds @__PURE__ annotation in front of all IIFE's that represent ES classes downleveled by TypeScript.
This annotation then enables Uglify 2.8+ to safely recognize if the class is not used and remove it.
You can use it webpack-plugin or cli.
Angular developers will need the bundle to be also processed by alxhub/ngo before the full effect can be seen.
