ReactJS is one of the most popular frontend frameworks for building fast, modern, and interactive web applications. Many developers assume that deploying React applications requires a VPS, Docker, or cloud platforms like AWS. But the truth is, you can easily host a ReactJS app in cPanel shared hosting using CloudLinux Node.js Selector.
If you are a developer, startup, or business in Chennai or anywhere in India, this guide will help you deploy your ReactJS project smoothly on cPanel hosting.
At ChennaiHost, we provide CloudLinux-powered hosting solutions that make React deployment simple, secure, and affordable.
Why CloudLinux is Perfect for Hosting ReactJS in cPanel
CloudLinux is widely used by hosting providers because it provides:
- Stable resource allocation (CPU, RAM limits per account)
- Better security isolation using CageFS
- Easy Node.js environment setup inside cPanel
- Improved performance compared to standard shared hosting
With CloudLinux, you can deploy ReactJS apps without worrying about server-level configurations.
Before You Start: What You Need
To deploy a ReactJS project on cPanel with CloudLinux, make sure you have:
✅ A cPanel hosting account with CloudLinux Node.js Selector enabled
✅ Your ReactJS project ready in your local system
✅ Node.js version compatibility (React usually works best with Node 16/18+)
✅ A domain or subdomain connected to your hosting
✅ FTP/File Manager access
If you’re hosting with ChennaiHost (Chennai, India), Node.js Selector is available on supported plans, making deployment easy.
Step 1: Build Your ReactJS Project
React projects cannot run directly like normal HTML unless you build them first.
Open your project folder and run:
npm install
npm run build
After building, React will generate a folder called:
📂 build/
This folder contains the final production-ready static files.
Step 2: Login to cPanel Hosting
Now login to your cPanel account.
Inside cPanel, you can deploy your React app using any of these methods:
- Upload build files directly to public_html
- Deploy React using Node.js Application Manager
- Use React with an Express server
In this blog, we will cover the best recommended method for CloudLinux hosting.
Step 3: Create a Subdomain (Recommended)
If you are hosting a React app, it is better to run it on a subdomain like:
- app.yourdomain.com
- portal.yourdomain.com
In cPanel:
➡️ Go to Domains → Subdomains
➡️ Create a new subdomain
➡️ Set document root as:
/public_html/app
This keeps your main website separate and clean.
Step 4: Upload React Build Files in File Manager
Now go to:
📌 cPanel → File Manager
Navigate to your folder:
public_html/app/
Upload the contents of your React build folder:
- index.html
- static/
- asset-manifest.json
- favicon.ico
- etc…
⚠️ Important: Upload the contents of build folder, not the build folder itself.
So your path should look like:
public_html/app/index.html
public_html/app/static/
Step 5: Fix React Router Issue (Very Important)
If your React app uses React Router (SPA routing), refreshing a page like:
app.yourdomain.com/about
may show a 404 error.
To fix this, create a .htaccess file inside your React folder:
📌 Location:
public_html/app/.htaccess
Add this code:
Options -MultiViews
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.html [L]
This will redirect all routes to React’s index.html, making routing work properly.
Step 6: Enable SSL (HTTPS)
Google prefers HTTPS websites and it improves user trust.
In cPanel:
➡️ Go to Security → SSL/TLS Status
➡️ Select your domain/subdomain
➡️ Click Run AutoSSL
After SSL activation, your React app will run securely as:
Step 7: Deploy ReactJS App Using CloudLinux Node.js Selector (Optional Advanced Method)
If you want React to run with Node.js (for SSR or API proxy), CloudLinux provides a Node.js application manager.
In cPanel, go to:
📌 Software → Setup Node.js App
Then:
- Click Create Application
- Choose Node.js version (Recommended: Node 18+)
- Set application root like:
/home/username/reactapp
- Set application URL (your subdomain)
- Set startup file (if using Express):
server.js
If you are hosting only the React build folder, you do NOT need Node.js runtime. Static hosting is enough.
Step 8: Clear Cache and Test Your React App
After deployment:
- Open your website in browser
- Use hard refresh:
Ctrl + Shift + R
Test important pages:
- Home page
- Routing URLs
- Contact form / API integration
- Mobile responsiveness
Step 9: Optimize React App for Faster Loading (Recommended)
React websites can load faster with small improvements.
Best optimization tips:
✅ Enable compression (GZIP/Brotli if supported)
✅ Use Cloudflare CDN
✅ Compress images (WebP format)
✅ Remove unused dependencies
✅ Use production build only
If you’re hosting with ChennaiHost, you can also enable performance improvements through server caching and CloudLinux optimizations.
Common Errors While Hosting ReactJS in cPanel (and Fixes)
1. Blank Page After Upload
Cause: Wrong homepage path or missing build files
Fix: Ensure index.html is in correct folder.
2. React Router 404 Error
Cause: Server doesn’t know SPA routes
Fix: Add .htaccess rewrite rule (Step 5)
3. CSS / JS Not Loading
Cause: Wrong base URL
Fix: Update package.json:
"homepage": "."
Then rebuild:
npm run build
4. Node.js App Not Starting in CloudLinux
Cause: Wrong startup file or missing dependencies
Fix: Run npm install inside Node.js App Manager.
