Installation

$3

- 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.

$3

You need Node.js and Electron.

``bash


Using npm


npm i eml-lib
`

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

$3

Quick start using the EML AdminTool:

`js
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.
