> Message propagation module for orbit-db

Default message propagation service for [orbit-db](https://github.com/orbitdb/orbit-db). Uses [IPFS](https://dist.ipfs.io/go-ipfs/floodsub-2) [pubsub](https://github.com/ipfs/go-ipfs/blob/master/core/commands/pubsub.go#L23).

# Install

This project uses [npm](http://npmjs.com/) and [nodejs](https://nodejs.org/).

```sh
npm install orbit-db-pubsub
```

## Usage

### API

#### subscribe(topic, onMessageHandler, onNewPeerHandler)

Listen for new messages in `topic`

`onMessageHandler` gets called when a message is received with signature `(topic, data)`

`onNewPeerHandler` gets called when a new peer joins with signature `(topic, peer)`

Returns a promise.

#### unsubscribe(topic)

Stop listening for new messages in `topic`

Returns a promise.

#### disconnect ()

Stop listening for new messages in all topics

Returns a promise.

#### publish(topic, data)

Publish `data` to a `topic`
