Separating Controllers

Why we separate Controllers?

Separating controllers in Express.js keeps the code organized and easy to manage. It helps with updating and scaling the app, improves code reuse and testing, and keeps different parts of the code separate. This also makes it easier for multiple developers to work on the app without interfering with each other.

How to create healthy endpoint with controller?

1. First create a folder in root directory by the name of controller.

   

2. next create a file by the name of health.js in controller .
