journeys(from, to, [opt])

from and to each must be in one of these formats:

// a station ID, in a format compatible to the profile you use
'900000013102'

// an FPTF `station` object
{
	type: 'station',
	id: '900000013102',
	name: 'foo station',
	location: {
		type: 'location',
		latitude: 1.23,
		longitude: 3.21
	}
}

// a point of interest, which is an FPTF `location` object
{
	type: 'location',
	id: '123',
	name: 'foo restaurant',
	latitude: 1.23,
	longitude: 3.21
}

// an address, which is an FTPF `location` object
{
	type: 'location',
	address: 'foo street 1',
	latitude: 1.23,
	longitude: 3.21
}

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

{
	when: new Date(),
	results: 5, // how many journeys?
	via: null, // let journeys pass this station
	passedStations: false, // return stations on the way?
	transfers: 5, // maximum of 5 transfers
	transferTime: 0, // minimum time for a single transfer in minutes
	accessibility: 'none', // 'none', 'partial' or 'complete'
	bike: false, // only bike-friendly journeys
	products: {
		suburban: true,
		subway: true,
		tram: true,
		bus: true,
		ferry: true,
		express: true,
		regional: true
	},
	tickets: false // return tickets? only available with some profiles
}

Response

Note: As stated in the Friendly Public Transport Format 1.0.1, the returned departure and arrival times include the current delay. The departureDelay/arrivalDelay fields express how much they differ from the schedule.

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)

// Hauptbahnhof to Heinrich-Heine-Str.
client.journeys('900000003201', '900000100008', {
	results: 1,
	passedStations: true
})
.then(console.log)
.catch(console.error)

The response may look like this:

Some profiles are able to parse the ticket information, if returned by the API. For example, if you pass tickets: true with the VBB profile, each journey will have a tickets array that looks like this:

[ {
	name: 'Berlin Tarifgebiet A-B: Einzelfahrausweis – Regeltarif',
	price: 2.8,
	tariff: 'Berlin',
	coverage: 'AB',
	variant: 'adult',
	amount: 1
}, {
	name: 'Berlin Tarifgebiet A-B: Einzelfahrausweis – Ermäßigungstarif',
	price: 1.7,
	tariff: 'Berlin',
	coverage: 'AB',
	variant: 'reduced',
	amount: 1,
	reduced: true
}, /* … */ {
	name: 'Berlin Tarifgebiet A-B: Tageskarte – Ermäßigungstarif',
	price: 4.7,
	tariff: 'Berlin',
	coverage: 'AB',
	variant: '1 day, reduced',
	amount: 1,
	reduced: true,
	fullDay: true
}, /* … */ {
	name: 'Berlin Tarifgebiet A-B: 4-Fahrten-Karte – Regeltarif',
	price: 9,
	tariff: 'Berlin',
	coverage: 'AB',
	variant: '4x adult',
	amount: 4
} ]

If a journey leg has been cancelled, a cancelled: true will be added. Also, departure/departureDelay/departurePlatform and arrival/arrivalDelay/arrivalPlatform will be null.
