State machines that run anywhere

// 1. Define a machine
const sdk = new OrchestateClient({ apiKey: 'orch_...' });

const machine = await sdk.machines.publish({
  slug: 'order-flow',
  definition: {
    initial: 'pending',
    states: {
      pending:  { on: { CONFIRM: 'confirmed', CANCEL: 'cancelled' } },
      confirmed: { on: { SHIP: 'shipped' } },
      shipped:  { on: { DELIVER: 'delivered' } },
      delivered: { type: 'final' },
      cancelled: { type: 'final' },
    }
  }
});

// 2. Create an instance
const instance = await sdk.instances.create({ machineSlug: 'order-flow' });

// 3. Send events
await sdk.instances.send(instance.id, { type: 'CONFIRM' });

// 4. Subscribe to live state
sdk.instances.subscribe(instance.id, (state) => {
  console.log('Current state:', state.value);  // 'confirmed'
});
