## Installation

```shell

npm install hafas-monitor-trips-server

```

## Usage

```js

const createServer = require('hafas-monitor-trips-server')

const server = createServer(hafas)

const subA = server.subscribe({

	north: 52.51, south: 52.4, west: 13.35, east: 13.38

})

const subB = server.subscribe({

	north: 52.505, south: 52.45, west: 13.355, east: 13.375

})

subA.on('stopover', stopover => console.log('A', stopover))

subB.on('stopover', stopover => console.log('B', stopover))

```

- `subA` and `subB` have overlapping bounding boxes, so they will share one monitor.

- `hafas` is a [`hafas-client`/`*-hafas`](https://npmjs.com/package/hafas-client) instance.

- `subscribe(bbox)` returns an [`EventEmitter`](https://nodejs.org/docs/latest-v12.x/api/events.html#events_class_eventemitter), emitting the same events as a [`hafas-monitor-trips`](https://npmjs.com/package/hafas-monitor-trips) instance.

See [`example.js`](example.js) for a full example.
