prismarine-auth

Quickly and easily obtain auth tokens to authenticate with Microsoft/Xbox/Minecraft/Mojang

Installation

npm install prismarine-auth

Usage

Authflow

Parameters

• username? {String} - Username for authentication
• cacherOrDir? {String | CacheFactory} - Where we will store your tokens (optional, defaults to node_modules) or a factory object that returns a Cache (see API.md)
• options {Object?}
  • [flow] {enum} Required if options is specified - see API.md for options
  • [forceRefresh] {boolean} - Clear all cached tokens for the specified username to get new ones on subsequent token requests
  • [password] {string} - If passed we will do password based authentication.
  • [authTitle] {string} - See the API.md
  • [deviceType] {string} - See the API.md
  • [scopes] {string[]} - Extra scopes to add to the auth request. By default, this includes Xbox and offline_access scopes; setting this will replace those scopes (but keep offline_access on msal flow which is required for caching). Note that the flows will differ depending on specified flow.
  • [abortSignal] {AbortSignal} - (Optional) An AbortSignal to cancel the request.
• onMsaCode {Function} - (For device code auth) What we should do when we get the code. Useful for passing the code to another function.

Examples

getMsaToken

const { Authflow, Titles } = require('prismarine-auth')

const userIdentifier = 'unique identifier for caching'
const cacheDir = './' // You can leave this as undefined unless you want to specify a caching directory
const flow = new Authflow(userIdentifier, cacheDir)
// Get a auth token, then log it
flow.getMsaToken().then(console.log)

Note: By default, this library will authenticate as Minecraft for Nintendo Switch, with a flow set to live. For non-Minecraft applications you should register for Microsoft Azure Oauth token. See https://learn.microsoft.com/en-us/entra/identity-platform/quickstart-register-app#register-an-application for more information on obtaining an Azure token. You then use it with the msal flow like this:

const flow = new Authflow(userIdentifier, cacheDir, { flow: 'msal', authTitle: '000-000-000-000' })

If flow is live, the default, then you can only specify existing Microsoft client IDs. This library exposes some default Microsoft client IDs under the exported Titles object. See the types for more information.

getMinecraftJavaToken

const { Authflow, Titles } = require('prismarine-auth')

const userIdentifier = 'any unique identifier'

// Get a Minecraft Java Edition auth token, then log it
flow.getMinecraftJavaToken({ fetchProfile: true }).then(console.log)
