Vercel Demo node js Project

This project demonstrates how to set up two different API routes on Vercel: one using Express and another using module exports.

Features

• Express API: A route that handles requests using an Express server.
• Module Exports API: A route that uses module exports for handling requests without a server.

API Routes

1. Module Exports Route: /api/module

   • Description: This route is handled by the module.js file. It uses a lightweight, serverless function to respond to requests.
   • Response: Returns a simple JSON message like {"message": "Hello from Module Export on Vercel!"}.

2. Express Route: /api/express

   • Description: This route is handled by the express.js file. It uses an Express server to manage requests and responses.
   • Response: Returns a JSON message like {"message": "Hello from Express on Vercel!"}.

Examples

• express : https://vercel-test-xi-virid.vercel.app/api/express
• module : https://vercel-test-xi-virid.vercel.app/api/module

Vercel Configuration

The vercel.json file defines the routing for the two APIs:

{
  "version": 2,
  "builds": [
    {
      "src": "src/*.js",
      "use": "@vercel/node"
    }
  ],
  "routes": [
    {
      "src": "/api/module",
      "dest": "/src/module.js"
    },
    {
      "src": "/api/express",
      "dest": "/src/express.js"
    },
    {
      "src": "/",
      "dest": "/src/main.js"
    }
  ]
}

Key Updates:

• API Routes section clearly defines the two routes (/api/module and /api/express).

• Each route is described in detail, including the file that handles the route and the type of response users can expect.

• and / for main route that is default url route

This simple structure should make it easy to understand what each route does.
