How to Deploy a React App to Vercel and AWS: A Complete Workflow
How to Deploy a React App to Vercel and AWS: A Complete Workflow
This guide provides a professional CI/CD pipeline to transition a React application from a local environment to a live production state using Vercel for frontend hosting and AWS for backend infrastructure.
What You'll Need
- Node.js and npm installed locally
- A GitHub account and repository
- A Vercel account
- An AWS account with IAM permissions
Steps
Step 1: Prepare the React Application
Ensure your project is optimized for production by running 'npm run build' to verify the build process. Remove any hardcoded API keys and move them into a .env file to maintain security across different environments.
Step 2: Push Code to GitHub
Initialize a Git repository and push your source code to a remote GitHub repository. This serves as the single source of truth and triggers the automated deployment pipeline whenever changes are merged into the main branch.
Step 3: Connect Repository to Vercel
Import your GitHub repository into the Vercel dashboard. Vercel will automatically detect the React framework and configure the necessary build settings and output directories.
Step 4: Configure Vercel Environment Variables
Navigate to the Project Settings in Vercel and add the environment variables defined in your .env file. This ensures the frontend can securely communicate with your AWS backend endpoints.
Step 5: Provision AWS Backend Resources
Deploy your API or database using AWS services such as Lambda, EC2, or RDS. Ensure that your security groups are configured to allow incoming traffic from Vercel's deployment IP ranges.
Step 6: Set Up AWS API Gateway
Create an API Gateway to act as the entry point for your backend services. Map your REST endpoints and enable CORS (Cross-Origin Resource Sharing) to allow requests from your Vercel domain.
Step 7: Execute Final Deployment
Trigger a production deployment in Vercel by merging your latest code into the main branch. Verify the live URL and test the integration between the React frontend and the AWS backend.
Expert Tips
- Use Vercel's Preview Deployments to test feature branches before merging to production.
- Implement AWS IAM roles with the principle of least privilege to secure your backend resources.
- Optimize your React bundle size using code-splitting to improve initial load times on Vercel.
- Set up a custom domain and SSL certificate via Vercel for a professional production presence.
