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.

Also, you will get some familiarity with…

Now you don’t have to navigate to your terminal to connect to Mongo Shell or use GUI tools like MongoDB Compass, Robomongo, etc. to perform basic Mongo operations.

With the extension, you can:
