Node.js support

This guide explains how to use Node.js with a managed Cloud Server.

Node.js is a free software platform in JavaScript aimed at network applications that need to be able to increase load.

Node.js is not currently available with Web hosting or Web + Email hosting.

Install Node.js

Requirements:

• Install NVM on the Cloud server

To install Node.js via NVM:

List the available versions:

Then, to install a specific version:

nvm install

Or to install the latest version:

nvm install node

Change the Node.js version, to set to version 6.3.1 (or another version):

Source :

Go to your cloud server's WebSSH console to set up NVM on your cloud server.

You need to source the .profile file :

source ~/.profile

You can then run the command :

nvm

Redirect web traffic to a specific port

Requirements:

• Install HAProxy on the Cloud server

By default, on the Cloud, web traffic is sent to Apache. To send requests to a Node script or other service (as long as it is "listening" on a port between 4000 and 4009), it needs to go via HAProxy.

This applies in particular to Express servers, Socket.IO, Meteor.js, Nuxt.js, Django, Flask, Ruby on Rails, even possibly Java (J2E), etc.

To do this, you need to ensure that the service is listening on a port between 4000 and 4009 (in particular using server.listen(4000) for Express or a basic HTTP Node server, or by other means depending on the type of project such as a configuration file, in the code etc.) and on all interfaces (0.0.0.0). You will also need to configure HAProxy as in the following example:

1. Log in to your Infomaniak Manager (manager.infomaniak.com)
2. Go to Cloud server
3. Click on the Cloud server concerned
4. From the left side panel, click on FastInstaller
5. From the applications list, click on the icon on the far right of FastInstaller and select Configure

Configure Node as a service

To configure Node as a service, we recommend using a "service systemd-user".
