An example webserver I wrote for a question on reddit on how to send data from a minecraft server running cc:Tweaked to a webpage.

I included a Dockerfile and two deploy scripts you can use to run it if you don't want to install a bunch of dependencies (besides Docker).

Running the webserver

Install node v24 then

cd webserver
npm install
npm start

The default port is 8081 The server will be accessible at http://localhost:8081

Running in Docker locally

Install docker then just do

sudo ./deploy_local.sh

Running in Docker on a remote machine

Assuming you have a remote server with ssh access set up and Docker installed on it:

EXAMPLESERVER_KEY=/path/to/your/ssh/key EXAMPLESERVER_HOST=<your-remote-ip> ./deploy_remote.sh

This creates a new docker context using ssh that builds and runs the container on your remote machine. The server will be accessible at http://<your-remote-ip>:8081

Sending data from computercraft

Put the file datasender.lua on your computercraft computer and then do

datasender http://<your-ip>:8081

This will send some fake data every 5 seconds to the web server which will populate in a list on the webpage.
