Node.js scripts belong in your :doc:`home <basics-home>`, not in your :doc:`docroot <web-documentroot>`.

Node.js is a server-side JavaScript interpreter. Node.js is commonly used to develop server-based applications, i.e. the scripts bind to a network port.


Release types

We provide different releases and apply security updates on a regular basis. Currently available versions are listed below.

Standard version

If you don't select a certain version, our default will be used. We decided to default to version 18, which is considered to be stable by the developers.

Show available versions

Use uberspace tools version list node to show all selectable versions:

[isabell@stardust ~]$ uberspace tools version list node
- 12
- 14
- 16
- 18
- 19
[isabell@stardust ~]$

Change version

You can select the Node.js version with uberspace tools version use node <version>. You can choose between release branches:

[isabell@stardust ~]$ uberspace tools version use node 14
Selected node version 14
The new configuration is adapted immediately. Patch updates will be applied automatically.
[isabell@stardust ~]$

Selected version

You can check the selected version by executing uberspace tools version show node on the command line:

[isabell@stardust ~]$ uberspace tools version show node
Using 'node' version: '19'
[isabell@stardust ~]$

Update policy

We update all versions on a regular basis. Once the support ends, the branch reaches its end of life (EOL), is no longer supported and will be removed from our servers. Even-numbered versions are long-term support (LTS) versions.

Branch State Supported Until
12 EOL April 2022
14 Maintenance April 2023
16 Active September 2023
18 Current April 2025
19 Current June 2023

Run node application in the background

To run your node application in the background we use supervisord.

Assuming your application files are located in the sub folder ~/my-node-app of your home directory. Then place a daemon service file called my-daemon.ini in ~/etc/services.d/:

command=npm run start

Start / Stop node daemon

Connection to webserver

Available package managers


npm, or the node package manager, is used to install and manage additional packages. We have preconfigured npm to install packages to your :doc:`home <basics-home>` when using the global (-g) option.


yarn is an alternative node package manager. It is used to install and manage additional packages of your node application.


You can use npx to quickly execute and test any npm package without the need to create a nodejs project around it. Check out to learn more.
