nearby(location, [opt])

This method can be used to find stations close to a location. Note that it is not supported by every profile/endpoint.

location must be an FPTF location object.

With opt, you can override the default options, which look like this:

{
	results: 8, // maximum number of results
	distance: null, // maximum walking distance in meters
	poi:      false, // return points of interest?
	stops:    true, // return stops/stations?
	subStops: true, // parse & expose sub-stops of stations?
	entrances: true, // parse & expose entrances of stops/stations?
	linesOfStops: false, // parse & expose lines at each stop/station?
	language: 'en' // language to get results in
}

Response

As an example, we're going to use the VBB profile:

const createClient = require('hafas-client')
const vbbProfile = require('hafas-client/p/vbb')

const client = createClient(vbbProfile, 'my-awesome-program')

client.nearby({
	type: 'location',
	latitude: 52.5137344,
	longitude: 13.4744798
}, {distance: 400})
.then(console.log)
.catch(console.error)

The response may look like this:
