NodeJS exec() shell

[IAmAFrenchFry]

Hi.

 

I am a small part of a Discord bot that has Minecraft-server-console-logging-in-a-discord-channel functionality. We currently use NodeJS' 

child_process.exec(command[, options][, callback])

which creates a shell and runs a command in it (in our case it is a start Minecraft server command). We then pass its STDOUT to a discord channel. I am looking for a way where whatever we type into that channel will be executed in the virtual shell that the Minecraft server is in. 

 

Thanks!

If you start the process using child_process.spawn rather than child_process.exec, it's a lot more powerful, although also a bit less user friendly. In particular, it provides a ChildProcess object, on which you can call childProcess.stdin.write("myData");

 

For example, you could do

const process = child_process.spawn("command", ["-arg1", "-arg2"]);

someEventProducer.on("userSentSomething", (input) => process.stdin.write(input));

This is equivalent to typing into the terminal if you ran the server manually.

 

If you go down this route, you probably need more error handling, etc, but hopefully this sets you in the right direction.
