boardgameio/boardgame.io: State Management and Multiplayer Networking for Turn-Based Games

Read the Documentation

boardgame.io is an engine for creating turn-based games using JavaScript.

Write simple functions that describe how the game state changes
when a particular move is made. This is automatically converted
into a playable game complete with online multiplayer
features, all without requiring you to write a single line of
networking or storage code.

• State Management: Game state is managed seamlessly across clients, server and storage automatically.
• Multiplayer: Game state is kept in sync in realtime and across platforms.
• AI: Automatically generated bots that can play your game.
• Game Phases: with different game rules and turn orders per phase.
• Lobby: Player matchmaking and game creation.
• Prototyping: Interface to simulate moves even before you render the game.
• Extendable: Plugin system that allows creating new abstractions.
• View-layer Agnostic: Use the vanilla JS client or the bindings for React / React Native.
• Logs: Game logs with the ability to time travel (viewing the board at an earlier state).
