How to Deploy a Next.js TypeScript App on Vercel and Add a Custom Domain

Deploying a Next.js application with TypeScript on Vercel is straightforward and allows you to use Vercel's powerful platform to host your project efficiently. In this guide, we'll go through the steps to deploy your Next.js TypeScript app using a GitHub repository and configure a custom domain for your deployment.

Step 1: Prepare Your Next.js TypeScript App

Before deploying, ensure that your Next.js app is ready and configured properly. Your project should have a valid package.json file and all dependencies should be installed. If you're starting fresh:

• Create a Next.js Project with TypeScript:

npx create-next-app@latest your-app-name --typescript        

• Navigate to Your Project Directory:

cd your-app-name        

• Test Locally:

Make sure your app is working locally by running:

npm run dev        

• Push to GitHub:

Initialize a git repository and push your code to a GitHub repository.

git init git add . git commit -m "Initial commit" git remote add origin https://github.com/your-username/your-repo-name.git git push -u origin main        

Step 2: Deploy to Vercel

1. Log In to Vercel: vercel.com
2. Import Your GitHub Repository:
3. Configure Deployment Settings:
4. Deployment:

Step 3: Add a Custom Domain to Your Vercel App

1. Navigate to Your Project Dashboard:
2. Add a Domain:
3. Update DNS Settings:
4. Verify Domain Ownership:

Step 4: Finalize and Test

• SSL Certificate: Vercel automatically provisions an SSL certificate for your custom domain, so your app will be served over HTTPS.
• Test Your Domain: Visit your custom domain (e.g., https://www.yourdomain.com) to ensure your app is running correctly.

Conclusion

Congratulations! You've successfully deployed your Next.js TypeScript app to Vercel and configured a custom domain. Now your application is live and accessible to the world with your domain name.

By leveraging Vercel's platform, you gain the benefits of a fast, secure, and globally distributed infrastructure, allowing you to focus more on building and less on maintaining your app.
