What you will get from this piece?

In this article, we’re going to build a server-rendered application in Nodejs by implementing:

  • Asset minification and compression using Gulp and Brotli.
  • A development environment where assets are minified and compressed in real-time.
  • A build process that can make distributable assets for deployment.
