🚀 Deploying a Node.js Express App on Vercel

This guide will help you deploy your plain Express.js app on Vercel step by step.

📌 Repository: Recursion Hub

🛠️ 1. Add vercel.json Configuration

Create a vercel.json file in the root of your project and add the following configuration:

{
  "version": 2,
  "rewrites": [{ "source": "/(.*)", "destination": "/server.js" }],
  "builds": [{ "src": "server.js", "use": "@vercel/node" }]
}

🔹 Explanation:

• rewrites: Redirects all incoming requests to server.js.
• builds: Specifies that server.js should be handled using Vercel’s Node.js runtime.

🚀 2. Deploy the App

Run the following commands in your project root:

# Install Vercel CLI globally
npm install -g vercel  

# Start local development server
vercel dev  

# Deploy to Vercel
vercel  

Once the deployment is complete, Vercel will provide a live URL for your app. 🎉
