WeChat Mini Game

WeChat Mini Game has special Worker restrictions. ESEngine provides CLI tools to solve this.

Platform Differences

Feature	Browser	WeChat
Dynamic scripts	✅	❌
Worker count	Multiple	Max 1
Script source	Any	Package files only

Using Worker Generator CLI

# Install
pnpm add -D @esengine/worker-generator

# Generate Worker files
npx esengine-worker-gen --src ./src --wechat

Configuration

class PhysicsSystem extends WorkerEntitySystem<PhysicsData> {
  constructor() {
    super(matcher, {
      enableWorker: true,
      workerScriptPath: 'workers/physics-worker.js'
    });
  }
}

Important Notes

1. Re-run CLI after modifying workerProcess
2. Worker functions must be pure (no this)
3. Pass config via systemConfig
