Jetpack

Features

• Write server logic in .jet files and load them live, with no Java build or restart
• Register commands, react to server events, and run timed intervals
• Reach the full Paper/Bukkit API through a native bridge
• Statically typed, so errors are caught before a script runs

Requirements

• Paper 1.21.10 or newer
• Java 21 or newer

Simple Example

listener PlayerJoinEvent onJoin(object event) {
  object player = event.player
  player.sendMessage($"Hello, {player.name}!")
}

Ecosystem

• Documentation: setup, syntax, scripts, and module reference
• Language Server: VS Code extension with highlighting, diagnostics, and completion for .jet files
• Skill: agent skill for writing, reviewing, and debugging .jet scripts
