How to Deploy Node.js App on Shared Hosting

You can run a small Node.js app on Domain India shared hosting without a server of your own: the cPanel and DirectAdmin servers have a Node.js application tool that starts your app and connects it to your domain. This guide shows how it works, what it can and cannot do, and when the App Platform or a VPS is the better home.

1. What we measured on our servers

We checked the shared servers on 23 September 2026:

Node.js 20 and older have reached end of life, so pick 22 or 24 if your app supports them. Version lists change over time; the panel shows the current one. The tool runs your app behind the Apache web server using Phusion Passenger, so your app does not open its own public port.

2. Is shared hosting right for your app?

Your app counts against the same resource limits as the rest of your account. If it hits them, visitors see errors such as 503 or 508. See Understanding hosting resource limits.

3. Prepare your app

Before you upload, make three small changes:

1. Listen on the port you are given. Use process.env.PORT, never a fixed port. Passenger routes traffic to your app.
2. Have a single startup file, such as app.js or server.js, that starts the server.
3. Build locally. If you use TypeScript, a bundler or a front-end framework, run the build on your own computer and upload the output, not the source.

A minimal Express start file:

const express = require('express');
const app = express();

app.get('/', (req, res) => res.send('Hello from Domain India'));

const port = process.env.PORT || 3000;
app.listen(port, () => console.log(`Listening on ${port}`));

4. Create the app in cPanel

Environment variables such as NODE_ENV=production or an API key go in the Environment variables section of the same form. Save, then restart the app. Keep secrets out of files inside public_html.

5. DirectAdmin

DirectAdmin has the same CloudLinux Node.js selector, installed as a plugin. The fields are the same: version, application root, application URL and startup file. Menu names in DirectAdmin can differ between skins; if you cannot find the Node.js option, ask support to point you to it.

6. Using SSH (optional)

Jailed SSH access is available on every shared hosting plan (cPanel, DirectAdmin, Webuzo). It is off by default; ask support to enable it for your account. See Enabling and accessing jailed SSH.

Once SSH is on, the app page shows a command that enters your app's environment, for example:

source /home/USERNAME/nodevenv/myapp/22/bin/activate && cd /home/USERNAME/myapp
npm install --omit=dev

Tools available inside the jailed shell vary by server, so check with support before you rely on a specific tool. Restart the app from the panel after any change.

7. Troubleshooting

• The app page shows an error or 503: check the startup file name and path, then read the log file named on the app's page. Restart after every fix.
• "Cannot find module": run Run NPM Install again, and check that package.json is in the application root.
• Changes do not show: restart the app. cPanel can also serve a cached copy of a page for up to 120 minutes, so add ?t=1 to the URL to check.
• The install or build runs out of memory: build on your own computer and upload the result, or move the app to the App Platform or a VPS.
• Background jobs stop: shared hosting runs your app to answer web requests. It is not a place for long-running workers or queues.

8. Where Node.js apps run best at Domain India

For anything beyond a small app, the App Platform is the dependable route. It detects and builds Node.js apps automatically, deploys from GitHub or with a deploy token, keeps the old version running if a build fails, and includes a PostgreSQL database and SSL. It has no SSH or root access. See Getting started with the App Platform.

If you need root access, your own process manager, Docker or several services, choose a VPS.
