Deploying Your First Full-Stack Application with Vercel and Heroku

Deployment is a critical phase in any web development project. After creating your full-stack application, hosting it on a live server is essential to make it accessible to users. In this guide, we’ll walk you through deploying a full-stack application using Vercel for the frontend and Heroku for the backend.

Why Choose Vercel and Heroku?

Vercel

• Optimized for frontend frameworks like Next.js and React.

• Automatic Continuous Deployment with GitHub, GitLab, or Bitbucket integration.

• Free-tier plan with generous limits for small projects.

Heroku

• Simplifies backend deployment for Node.js, Express, or other server-side applications.

• Provides a fully managed hosting environment with a free-tier plan.

• Supports multiple languages and databases like MongoDB and PostgreSQL.

By using Vercel and Heroku together, you can efficiently deploy your frontend and backend components, ensuring seamless integration.

Prerequisites

1. A full-stack application with:

   • Frontend: Built using frameworks like React or Next.js.

   • Backend: Built with Node.js and Express (or any backend framework).

   • A connected database (e.g., MongoDB Atlas).

2. Accounts on:

   • Vercel

   • Heroku

3. Git installed on your system.

4. Basic understanding of git commands.

Step 1: Prepare Your Frontend for Deployment

1.1. Ensure Your Frontend is Ready

• Check your package.json file to ensure scripts like build and start are correctly configured.

• Test your application locally to confirm it works as expected.

1.2. Push Your Frontend Code to GitHub

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

1.3. Deploy to Vercel

1. Go to Vercel and log in.

2. Click on "New Project" and import your GitHub repository.

3. Configure the project settings:

   • Ensure the framework is detected correctly (e.g., Next.js or React).

   • Add environment variables if needed.

4. Click Deploy and wait for Vercel to build and deploy your project.

Step 2: Prepare Your Backend for Deployment

2.1. Configure Your Backend

• Ensure your backend is production-ready:

  • Use environment variables for sensitive data.

  • Test API routes locally.

2.2. Push Your Backend Code to GitHub

Similar to the frontend, initialize a Git repository for your backend and push it to GitHub.

cd backend
git init
git add .
git commit -m "Backend initial commit"
git remote add origin https://github.com/yourusername/your-backend-repo.git
git push -u origin main

2.3. Deploy to Heroku

1. Install the Heroku CLI and log in:

    heroku login
   

2. Create a new Heroku app:

    heroku create your-app-name
   

3. Add a Procfile to specify the entry point of your app:

    echo "web: node index.js" > Procfile
   

4. Push your code to Heroku:

    git push heroku main
   

5. Add environment variables:

    heroku config:set VARIABLE_NAME=value

Step 3: Connect Frontend and Backend

3.1. Update Backend API URL in Frontend

• Replace local backend URLs in your frontend code with the live Heroku URL.

    const API_BASE_URL = "https://your-app-name.herokuapp.com";
  

3.2. Test the Integration

• Deploy the updated frontend to Vercel.

• Verify that the frontend communicates correctly with the backend.

---

Step 4: Verify Your Deployment

4.1. Test Both Deployments

• Visit your frontend URL (e.g., https://your-frontend.vercel.app) and ensure the app works as expected.

• Test all API routes via the frontend or tools like Postman.

4.2. Monitor Logs

• On Vercel, monitor deployment logs to debug frontend issues.

• Use Heroku’s CLI to check backend logs:

    heroku logs --tail
  

---

Tips for Successful Deployment

1. Optimize for Performance:

   • Use CDN services for static assets.

   • Enable caching for frequently accessed data.

2. Monitor Errors:

   • Set up tools like Sentry or New Relic for error tracking.

3. Use HTTPS:

   • Both Vercel and Heroku automatically enable HTTPS for free.
