Deploying React.js Apps

After developing a React app, the next critical step is deploying it so users can access it online. React applications can be deployed on various platforms like Netlify, Vercel, GitHub Pages, and Heroku, depending on your preferences and project needs. Let’s walk through the steps of deploying a React app.


Common Platforms for Deploying React Apps

Netlify:
  • Provides continuous deployment, automatic build previews, and an easy-to-use interface.
  • Great for hosting static sites with custom domain support.
  • Vercel:
  • Popular for its seamless integration with Next.js, but also excellent for React apps.
  • It offers easy deployments, instant rollbacks, and custom domains.
  • GitHub Pages:
  • A free service that hosts static websites straight from a GitHub repository.
  • Ideal for smaller projects or personal portfolios.
  • Heroku:
  • A cloud platform that lets you deploy web apps with backend support.
  • Good for full-stack applications

  • Step-by-Step Guide to Deploying on Netlify

    1. Build the React App:

    Run the following command in the terminal to create a production build

    				
    					npm run build
    
    				
    			

    This will create a build folder containing all the necessary files for deployment.

    2. Create a Netlify Account:

    Sign up at Netlify and log in

    3. Connect GitHub Repository:

  • On Netlify’s dashboard, click New site from Git.
  • Select the repository where your React project is hosted.
  • 4. Configure Build Settings:
    Netlify will detect the build settings automatically. Ensure the build command is set to
    				
    					npm run build
    
    				
    			
    The publish directory should be build.
    5. Deploy:
  • Click the deploy button and wait for the process to complete.
  • Netlify will provide you with a live URL once the deployment is finished. You can also set up a custom domain if needed.

  • Deploying on Vercel

    1. Install Vercel CLI (optional but recommended):

    				
    					npm install -g vercel
    
    				
    			

    2. Build the React App:

    				
    					npm run build
    
    				
    			

    3. Deploy:

    In the terminal, run:

    				
    					vercel
    
    				
    			

    Follow the prompts to link the project to your Vercel account and select the correct settings.


    Best Practices for React App Deployment

  • Optimize for Production: Always create a production build using npm run build to optimize your app for better performance.

  • Environment Variables: Use environment variables for sensitive information, like API keys, by defining them in .env files and configuring them appropriately for deployment.

  • Continuous Deployment: Platforms like Netlify and Vercel offer continuous deployment, meaning your app will automatically update when you push new changes to the repository.
