## Installing

```shell
npm install vbb-stations
```


## Usage

The [npm package](https://npmjs.com/vbb-stations) contains [*Friendly Public Transport Format* 1.2.1](https://github.com/public-transport/friendly-public-transport-format/blob/1.2.1/spec/readme.md) `station`s and `stop`s. `weight` is the sum of all arrivals & departures at a station, weighted by mode of transport.

```js
[
	{
		type: 'station',
		id: '900000009101',
		name: 'U Amrumer Str.',
		location: {
			type: 'location',
			latitude: 52.542202,
			longitude: 13.349534
		},
		weight: 3563
	}
]
```

You can filter all stations by `id` or any property ([`lodash.get`](https://lodash.com/docs/#get) will be used).

```js
const stations = require('vbb-stations')

console.log(stations('900000009101')) // query a single station
console.log(stations({ // filter by property
	weight: 3563,
	'location.latitude': 52.542202
}))
```

`full.json` contains all stops of each station and unshortened names.

```js
require('vbb-stations/full.json')['900000009101']
```

One entry looks like this:

```js
{
	type: 'station',
	id: '900000009101',
	name: 'U Amrumer Str. (Berlin)',
	location: {
		type: 'location',
		latitude: 52.542202,
		longitude: 13.349534
	},
	weight: 3284.25,
	stops: [
		{
			type: 'stop',
			id: '070101000865',
			name: 'U Amrumer Str. (Berlin)',
			station: '900000009101',
			location: {
				type: 'location',
				latitude: 52.542202,
				longitude: 13.349534
			}
		},
		// …
		{
			type: 'stop',
			id: '070201092402',
			name: 'U Amrumer Str. (Berlin)',
			station: '900000009101',
			location: {
				type: 'location',
				latitude: 52.542202,
				longitude: 13.349534
			}
		}
	]
}
```

`names.json` contains only shortened names.

```js
require('vbb-stations/names.json')['900000009101'] // U Amrumer Str.
```


## API

`stations([pattern])`

`pattern` can be one of the following:

- a station ID, like `900000009101`
- `'all'`
- an object like `{weight: 42, name: 'Alt Pinnow'}`, with each property being mandatory
