yggdrasil

A Node.js client for doing requests to yggdrasil, the Mojang authentication system, used for Minecraft and Scrolls.

Usage

$ npm install yggdrasil

Client

//init
const ygg = require('yggdrasil')({
  //Optional settings object
  host: 'https://authserver.mojang.com' //Optional custom host. No trailing slash.
});

//Authenticate a user
ygg.auth({
  token: '', //Optional. Client token.
  agent: '', //Agent name. Defaults to 'Minecraft'
  version: 1, //Agent version. Defaults to 1
  user: '', //Username
  pass: '', //Password
  requestUser: false //Optional. Request the user object to be included in response
}).then(
  (response)=>{},
  (error)=>{}
);

//Refresh an accessToken
ygg.refresh(oldAccessToken, clientToken, true).then(
  ({accessToken, clientToken, user?})=>{},
  (error)=>{}
);
// Note that requestUser is an optional parameter. If set to true, it requests the user object from Mojang's authentication servers as well.

//Validate an accessToken
ygg.validate(token).then(
  (response)=>{},
  (error)=>{}
);

//Invalidate all accessTokens
ygg.signout(username, password).then(
  (response)=>{},
  (error)=>{}
);

Server

const yggserver = require('yggdrasil').server({
  //Optional settings object
  host: 'https://authserver.mojang.com' //Optional custom host. No trailing slash.
});

//Join a server (clientside)
yggserver.join(token, profile, serverid, sharedsecret, serverkey).then(
  (response)=>{},
  (error)=>{}
);

//Join a server (serverside)
yggserver.hasJoined(username, serverid, sharedsecret, serverkey).then(
  (clientInfo)=>{},
  (error)=>{}
);

Proxy Support

const ProxyAgent = require('proxy-agent');

const ygg = require('yggdrasil')({
  //Any type of HTTP Agent 
  agent: new ProxyAgent('https://example.com:8080')
});

With ES6 Named Exports

/**
 * Import Client or Server from 'yggdrasil/es6'.
 * Note that the library is stateless when imported this way vs the CommonJS way.
 * You have typings though ;D
 */
import { Client as ygg, Server as yggServ } from 'yggdrasil/es6'

// Use it like you normally would.

ygg.validate(token).then(
  (response)=>{}, 
  (error)=>{}
);

yggServ.join(token, profile, serverid, sharedsecret, serverkey).then(
  response=>{},
  error=>{}
);
