Last updated 4th February 2021

Objective

You've subscribed to a Web POWER web hosting plan to deploy Node.js applications, and you want to begin developing your project using Express.

This guide will explain how to deploy a simple Hello World server on Express.

Find out how to install Express on your POWER web hosting plan.

Requirements

• a Node.js POWER web hosting plan
• access to the OVHcloud Control Panel

If you have just started to use your Web POWER web hosting plan, we suggest to have a look at our Getting started with a POWER web hosting plan guide before going further.

Instructions

Let's suppose you have the default configuration for Node.js hosting:

• Runtime: nodejs 14
• Entrypoint: index.js
• DocumentRoot: www

Connect via SSH to your POWER web hosting, and install Express using npm:

npm install express --save

Then go to the www folder and create an index.js file there:

index.js

const express = require('express');
const port = 3000;
const msg = `Hello World from NodeJS ${process.version}\n`;
const app = express();app.get('/', function (req, res) {
res.send(msg);
});
app.listen(port);

Restart your instance and your Express Hello World will be online.

Terminal output:

~/www $ cd www
~/www $ node -v
v14.13.0
~/www $ npm install express --save
~/www $ vi index.js
const express = require('express');
const port = 3000;
const msg = `Hello World from NodeJS ${process.version}\n`;
const app = express();app.get('/', function (req, res) {
res.send(msg);
});
app.listen(port);
~/www $ mkdir -p tmp
~/www $ touch tmp/restart.txt
