Pierce 3f0ceae5b6 Change how authentication gets passed
I was making a launcher of my own, and I found it very hard to juggle with having the auth in the options since I needed to set the client events before I actaully had the users login. This will fix the issue i was running into!

This project is near complete.

Build Status

MCLC is a NodeJS solution for launching modded and vanilla Minecraft without having to download and format everything yourself. Basically a core for your Electron or script based launchers.

Getting support

Since people seem to use this, I've created a Discord server for anyone who needs to get in contact with me or get help! https://discord.gg/8uYVbXP

Installing

npm i minecraft-launcher-core

Standard Example

const { Client, Authenticator } = require('minecraft-launcher-core');

let opts = {
    clientPackage: null,
    root: "./minecraft",
    os: "windows",
    version: {
        number: "1.14",
        type: "release"
    },
    memory: {
        max: "6000",
        min: "4000"
    }
}

const launcher = new Client(opts);
launcher.launch(Authenticator.getAuth(username, password));

launcher.on('debug', (e) => console.log(e));
launcher.on('data', (e) => console.log(e));
launcher.on('error', (e) => console.log(e));
