---

Features

• Java: Automatically download and install Java.
• Bootstraps ¹: Auto-update your launcher.
• Maintenance ¹: Block the launcher during maintenance.
• Server status: Displaying server information (from Minecraft 1.4 to the latest Minecraft version)
• News ¹: Displaying news.

Installation

Software requirements

• Node.js 20 or higher: see Node.js;
• Electron 23 or higher: please install it with npm i electron if you use Microsoft Authentication.

To get all the capacities of this Node.js library, you must set up your EML AdminTool website! Without it, you can only use Minecraft Vanilla, and many features will be disabled (such as News, Bootstrap, etc.).

If you don't want to use EML AdminTool, you should rather use the Minecraft Launcher Core library.

EML Lib installation

You need Node.js and Electron.

# Using npm
npm i eml-lib

eml-lib package includes TypeScript typings, so you don't need to install @types/eml-lib.

Quick start

Quick start using the EML AdminTool:

const EMLLib = require('eml-lib')

const launcher = new EMLLib.Launcher({
  url: 'https://admintool.electron-minecraft-launcher.com',
  serverId: 'eml',
  account: new EMLLib.CrackAuth().auth('GoldFrite')
})

launcher.launch()

Please refer to the docs for more information.
