# PolisenAPI

Simple JavaScript API client for [Polisen API](https://polisen.se/om-polisen/om-webbplatsen/oppna-data/api-over-polisens-handelser/).

## Getting started

Requires `node` >= 8.9.0

```
npm install --save polisen-api
```

# Usage

Initialize

```javascript
const PolisenAPI = require('polisen-api')
```

Get police stations

```javascript
api.fetchPoliceStations()
.then((stations) => {
console.log(stations.map(s => s.name))
})
```

Get latest events

```javascript
const api = new PolisenAPI()

api.fetchEvents()
.then((events) => {
console.log(events.map(e => e.name))
})
```

:warning: The API does __not__ let you filter further back than the last ~500 events or so. See [this note on filters](#filter-note) for more info.

Filter events on location
```javascript
api.fetchEvents({ locations: ['Stockholm', 'Järfälla'] })
```

Filter events on type

```javascript
api.fetchEvents({ types: ['Djur skadat/omhändertaget', 'Trafikbrott'] })
```

Filter on year/month/day/hour
```javascript
api.fetchEvents({ date: { year: 2018 } })
api.fetchEvents({ date: { year: 2018, month: 8 } })
api.fetchEvents({ date: { year: 2018, month: 8, day: 16 } })
api.fetchEvents({ date: { year: 2018, month: 8, day: 16, hour: 8 } })
```

Multiple filters
```javascript
api.fetchEvents({
date: { year: 2018 },
locations: ['Järfälla'],
types: ['Djur skadat/omhändertaget'],
})
```

Throws errors for invalid arguments

```javascript
api.fetchEvents({ date: { year: 2018, month: '-1' } })
//
```

If you only want to get build the URL
```javascript
api.getEventsURL({ locations: ['Stockholm'], date: { year: 2018, month: '3' } })
// supports the same params as fetchEvents

api.getPoliceStationsURL()
```

You can require all available event types

```javascript
const policeEventTypes = require('polisen-api/event_types_data')
```

Add latitude and longitude to location data

```javascript
const apiLatLong = require('polisen-api/api-lat-long')

api.fetchEvents()
.then(events => {
events.map(event => apiLatLong(event.location))
// { latitude: 63.176683, longitude: 14.636068, ...event.location }
})

api.fetchPoliceStations()
.then(stations => {
stations.map(station => apiLatLong(station.location))
// { latitude: 63.176683, longitude: 14.636068, ...station.location }
})
```

## Filter note

When given no parameters the API returns last 500 events. The API __does not__ let you filter more than a week back (during my very limited testing), so unfortunately you can't do historical analysis.
