Run a Node.js or Python application

Choose a suitable Node.js or Python type when it is offered. Minecraft-specific tools are not applicable to these applications.

Step by step

Upload your application into /server, including its dependency declarations.
Use Versions and the available startup controls to select a compatible runtime and entry point.
Follow the application requirements for installing dependencies; do not assume an upload automatically installs every package.
For a network service, listen on an assigned port and on the container interface, normally 0.0.0.0.
Start the application and use the console to inspect errors.

Check the assigned address and runtime usage. A process being online does not prove that its HTTP or bot connection has finished initializing.

Do not publish tokens or passwords in logs, screenshots or public downloads.
