just realized that CLI 6 doesn't support anymore some NPM global variables

@fercaveri Hey, Did you find a workaround for this issue? I am getting this error while decompressing data compressed on the server. I am using zlib to do this. Please advise if you have some advice for me.

Little late but I was able to fix this issue by install an npm package next-tick and then within the polyfill.ts file adding this little snippet to satisfy some of the globals that would normally exist in a node.js environment

(window as any).global = window;
global.Buffer = global.Buffer || require('buffer').Buffer;
global.process = {
  env: { DEBUG: undefined },
  version: [],
  nextTick: require('next-tick')
} as any;

For me however this only kicked the problem down the road because the real issue is that you are using a package that was intended to be used on a node.js server and are instead using it within an Angular application.
