Step-by-Step Guide to Deploying Your Next.js App to Vercel

Step 1: Prepare Your Next.js Application

Ensure your Next.js application is ready for deployment. Your project should have a package.json file and a build script.

Example package.json:

{
  "name": "nextjs-app",
  "version": "1.0.0",
  "scripts": {
    "dev": "next dev",
    "build": "next build",
    "start": "next start"
  },
  "dependencies": {
    "next": "latest",
    "react": "latest",
    "react-dom": "latest"
  }
}

Step 2: Push Your Project to a Git Repository

If you haven’t already, initialize a Git repository for your project and push it to GitHub, GitLab, or Bitbucket.

git init
git add .
git commit -m "Initial commit"
git remote add origin <repository-url>
git push -u origin main

Step 3: Sign In to Vercel

Go to Vercel and sign in using your preferred Git provider (GitHub, GitLab, or Bitbucket).

Step 4: Import Your Project

1. After signing in, click the "New Project" button on your Vercel dashboard.

2. Select your Git provider and authorize Vercel to access your repositories.

3. Find and import your Next.js repository.

Step 5: Configure Your Project

During the import process, Vercel will detect that your project is a Next.js application and will automatically configure the build and output settings. You can review and adjust these settings if needed.

• Build Command: npm run build

• Output Directory: .next

Step 6: Deploy Your Application

Click the "Deploy" button to start the deployment process. Vercel will build your application and deploy it to their edge network.

Step 7: View Your Live Application

Once the deployment is complete, Vercel will provide a unique URL for your live application. You can also configure a custom domain if you have one.

Additional Features and Configuration

Custom Domains

To add a custom domain to your project:

1. Go to your project’s dashboard on Vercel.

2. Click the "Settings" tab.

3. Under "Domains", click "Add" and follow the instructions to configure your custom domain.

Environment Variables

If your application requires environment variables, you can add them in the Vercel dashboard:

1. Go to your project’s dashboard on Vercel.

2. Click the "Settings" tab.

3. Under "Environment Variables", add your variables.

Serverless Functions

Next.js supports serverless functions, which can be deployed to Vercel seamlessly. Place your functions in the pages/api directory.

Example API Route:

// pages/api/hello.js
export default function handler(req, res) {
  res.status(200).json({ message: 'Hello from Vercel!' });
}

Deploying your app with this route will automatically configure the serverless function.

Automatic Deployments

Vercel will automatically redeploy your application whenever you push changes to the connected Git repository. This ensures that your app is always up-to-date.
