# Thalamus

An opinionated application messaging framework based on MQTT.

### Differences from plain MQTT

```diff
+ RPC support
+ Server redundancy / load-balancing
- Guaranteed delivery (MQTT QoS 1 / 2)
```

Messages requiring acknowledgement must use RPC and applications are expected to
implement their own retry mechanisms.

### API

#### `class Thalamus`

-   `constructor(serverOptList: MQTT.IClientOptions[])`
-   `async publish(topic: string, payload: Uint8Array)`
-   `async subscribe(topic: string, handler: SubHandler)`
-   `async unsubscribe(topic: string, handler?: SubHandler)`
-   `async call(topic: string, params: Param = {}, opt = defaultOptions): Promise<Result>`
-   `async register(topic: string, handler: (param, topic) => Result)`
