The offical rust/cargo package that provides essential functionality for Minecraft client launchers.

Features

Essential: Offers core functionality for Minecraft Client Launchers.
Simplifies: Streamlines the process of building Minecraft Client Launchers.
Fast: Delivers superior performance in authentication and launching.
Safe: Ensures safety by forbidding unsafe code.
Beginner Friendly: Comprehensive documentation and examples/templates available on GitHub.

Package Versions

If your looking to use a package other than rust/cargo you might want to have a look at:

Installation

Add minecraft-essentials to your project:

cargo add minecraft-essentials

Add the following to your Cargo.toml:

[dependencies]
minecraft-essentials = "0.2.9"

Usage

Authentifcation

OAuth Custom Authentifcation | OAuth2.0

This example demonstrates how to use the OAuth authentication method provided by minecraft-essentials, oauth feature.

use minecraft_essentials::*;

async fn Oauth(client_id: &str, client_secret: &str, port: Option<u16>, bedrockrel: bool) {
// Initialize the OAuth authentication object
let auth = Oauth::new(client_id, port);

// Print the URL needed for authentication
println!("URL: {}", auth.url());

// Launch the authentication process
 let auth_info = auth.launch(bedrockrel, client_secret).await;

// Print the authentication information
println!("{:?}", auth_info)
}

fn main() {
    Oauth("CLientID", "ClientSecret", None, false);
}

Device Code Custom Authentication | DeviceCode

[!WARNING] This is still work in progress so it may change.

This example demonstrates how to use the Device Code authentication method provided by minecraft-essentials, devicecode feature.

use minecraft_essentials::*;


async fn deviceCode(client_id: &str) {
  // Create a new device code instance 
  let code = DeviceCode::new(client_id).expect("Expected Code");

  // Print the device code information 
  println!("Stuff Here: {}", code.preinfo());

  // Launch the authentication process 
  let code_info = code.launch().await?;
}

fn main() {
    // Initialize Device Code authentication with your client ID 
    deviceCode("111231209837123098712");
}

Acutal Minecraft Authentfication

[!CAUTION] This is currently in the roadmap for 0.2.12-14 currently it's not avalible.

Launching

Custom Launching

use minecraft_essentials::Launch;
use std::path::Path;

let args = vec!["--uuid:LauncherUUID".to_string(), "--token:Beartoken".to_string()];
let jre_path = Path::new("/path/to/jre").to_path_buf();
let java_exe = "/your/java/path";

// Init the instance of launch
let launch = Launch::new(args, java_exe.to_string(), Some(jre_path.clone()), Some(false)).expect("Expected Launch");

// Grab the info to verify that your doing everything currect.
let launch_info = launch.info();
println!("Launching with: {:?}", launch_info);

let _ = launch.launch_jre();
