node.js express export routes

First, create a new JavaScript file to define and export the routes.

Define the Express router by requiring the 'express' module and creating a new instance of the router.

Define the route using the router's HTTP verbs such as get, post, put, delete, etc., followed by the route path and a callback function to handle the request and response.

Inside the callback function, you can perform any necessary operations, such as fetching data from a database or processing the request in some way.

Export the router using module.exports to make it accessible to other parts of your application.

In the main app file, require the exported router file using require() and use it by specifying the base URL path for the routes.
