AuraJS

Write JavaScript 2D and 3D games, compile to native. Create, play, and publish from your terminal.

Alpha status: AuraJS is still in alpha and not ready for production use.

Website: aurajs.gg

Quickstart

npm install -g auramaxx
auramaxx create my-game
cd my-game
npm run dev

One-off bootstrap without a global install:

npx auramaxx

Inside a scaffolded game, use the shorter auramaxx alias or the generated npm run ... scripts for local engine commands.

Play an Example

npm install -g auramaxx
auramaxx play auracraft

# or run a published game wrapper directly
npx auracraft play

Fork a Game

npm install -g auramaxx
auramaxx fork auramon

Working With AI Agent

Inside your codebase:

cd <your-codebase>
npx -y skills add Aura-Industry/auramaxx

Then use https://www.aurajs.gg/docs for engine docs and API references.

Multiplayer TL;DR

auramaxx create my-room-game --template multiplayer
cd my-room-game
npm run dev

# second terminal
npm run join -- AURA2P

Keep that same flow and add internet-backed rooms with either:

• aura.config.json -> multiplayer.relay = "relay.aurajs.gg"
• or AURA_MULTIPLAYER_RELAY_HOST=relay.aurajs.gg

Use Multiplayer Quickstart for the short multiplayer doc, or Multiplayer Party Example for the same-project example with diagnostics and room chat.
