# PubSub RPC

[![](https://img.shields.io/npm/v/@akiroz/pubsub-rpc)](https://www.npmjs.com/package/@akiroz/pubsub-rpc)
![test](https://github.com/akiroz/pubsub-rpc/workflows/test/badge.svg)

A generic RPC mechanism for Pub/Sub transports based on MsgPack

Supports NodeJS and modern browsers.

### Installing

```
$ yarn add @akiroz/pubsub-rpc
```

### Why not JSON-RPC?

Native binary support for passing large binary payloads.

### Mechanism

0. Callee subscribe to `topic`
1. Caller subscribe to `topic/${base64(id)}`
2. Caller publish to `topic` with a binary `id` (default 16 byte) in the payload
3. Callee calls RPC handler with `params` in the payload to get `result` or `error` response
4. Callee publish response to `topic/${base64(id)}`
5. Caller unsubscribe from `topic/${base64(id)}`

## API

[See tests](test/index.spec.ts) for a basic use case that simply uses an EventEmitter as the Pub/Sub mechanism.
