Package Exports

eml-lib
eml-lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (eml-lib) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation

Software requirements

Node.js 15.14.0 or higher: see Node.js;
Electron 15.0.0 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 the EML AdminTool, you should rather use the Minecraft Launcher Core library.

EML Core installation

You need Node.js and Electron.

# Using npm
npm i emlcore

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

Quick start

Quick start using the EML AdminTool:

const EMLCore = require('emlcore')

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

launcher.launch()

Please refer to the documentation for more information.
