I am creating my own Minecraft launcher and I want to know the terminal command for opening Minecraft Java. I've tried many solutions online but most of them are outdated or only for Windows.

I already authenticated with https://authserver.mojang.com/authenticate, and now I want to run a terminal command which opens Minecraft given the username/password or access token.



So I have found a solution. I am using Electron (https://www.electronjs.org/) and Node JS to build my Minecraft Launcher. And I have found a npm package that gives exactly what I want: https://github.com/Pierce01/MinecraftLauncher-core.

This package uses Node JS to launch Minecraft with authentication and all.
