We provide different releases and apply security updates on a regular basis. Currently, these Node.js versions are available: 12, 14, and 16
If you don’t select a certain version, our default will be used. We decided to default to version 16, which is considered to be stable by the developers.
Show available versions¶
uberspace tools version list node to show all selectable versions:
[isabell@stardust ~]$ uberspace tools version list node - 12 - 14 - 16 [isabell@stardust ~]$
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 ~]$
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: '16' [isabell@stardust ~]$
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.
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
[program:my-daemon] directory=/home/isabell/my-node-app command=npm run start autostart=true autorestart=true environment=NODE_ENV=production
supervisord to look for the new
[isabell@stardust ~]$ supervisorctl reread my-daemon: available
And then start your daemon:
[isabell@stardust ~]$ supervisorctl update my-daemon: added process group
Start / Stop node daemon¶
To start a non-running service or stop a running one, use
supervisorctl start my-daemon and
supervisorctl stop my-daemon. To restart a service, you can also use
supervisorctl restart my-daemon.
[isabell@stardust ~]$ supervisorctl start my-daemon my-daemon: started [isabell@stardust ~]$ supervisorctl stop my-daemon my-daemon: stopped [isabell@stardust ~]$ supervisorctl restart my-daemon my-daemon: stopped my-daemon: started
Connection to webserver¶
In order to make your application accessable from the outside, you need to connect it to the webserver, using a web backend.
Please note that your application must listen on the IP
0.0.0.0. You can choose any port
between 1024 and 65535.
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 home when using the global (
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 nodejs.dev to learn more.
