Change uri to

const url='mongodb://0.0.0.0:27017/';

This happened probably because the MongoDB service isn't started.

Follow the below steps to start it:

  1. Go to Control Panel and click on Administrative Tools. (in Windows the path will be: Control Panel\System and Security\Administrative Tools)
  2. Double click on Services. A new window opens up.
  3. Search MongoDB.exe. Right click on it and select Start.

The server will start. Now execute npm start again and the code might work this time.
