# `journeys(from, to, [opt])`
|
||
|
||
`from` and `to` each must be in one of these formats:
|
||
|
||
```js
|
||
// 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',
|
||
poi: true,
|
||
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:
|
||
|
||
```js
|
||
{
|
||
// Use either `departure` or `arrival` to specify a date/time.
|
||
departure: new Date(),
|
||
arrival: null,
|
||
|
||
earlierThan: null, // ref to get journeys earlier than the last query
|
||
laterThan: null, // ref to get journeys later than the last query
|
||
|
||
results: null, // number of journeys – `null` means "whatever HAFAS returns"
|
||
via: null, // let journeys pass this station
|
||
stopovers: false, // return stations on the way?
|
||
transfers: -1, // Maximum nr of transfers. Default: Let HAFAS decide.
|
||
transferTime: 0, // minimum time for a single transfer in minutes
|
||
accessibility: 'none', // 'none', 'partial' or 'complete'
|
||
bike: false, // only bike-friendly journeys
|
||
walkingSpeed: 'normal', // 'slow', 'normal', 'fast'
|
||
// Consider walking to nearby stations at the beginning of a journey?
|
||
startWithWalking: true,
|
||
products: {
|
||
// these entries may vary from profile to profile
|
||
suburban: true,
|
||
subway: true,
|
||
tram: true,
|
||
bus: true,
|
||
ferry: true,
|
||
express: true,
|
||
regional: true
|
||
},
|
||
tickets: false, // return tickets? only available with some profiles
|
||
polylines: false, // return a shape for each leg?
|
||
subStops: true, // parse & expose sub-stops of stations?
|
||
entrances: true, // parse & expose entrances of stops/stations?
|
||
remarks: true, // parse & expose hints & warnings?
|
||
scheduledDays: false, // parse which days each journey is valid on
|
||
language: 'en', // language to get results in
|
||
}
|
||
```
|
||
|
||
## Response
|
||
|
||
*Note:* As stated in the [*Friendly Public Transport Format* v2 draft spec](https://github.com/public-transport/friendly-public-transport-format/blob/3bd36faa721e85d9f5ca58fb0f38cdbedb87bbca/spec/readme.md), 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](../p/vbb):
|
||
|
||
```js
|
||
const createClient = require('hafas-client')
|
||
const vbbProfile = require('hafas-client/p/vbb')
|
||
|
||
const client = createClient(vbbProfile, 'my-awesome-program')
|
||
|
||
// Hauptbahnhof to Heinrich-Heine-Str.
|
||
await client.journeys('900000003201', '900000100008', {
|
||
results: 1,
|
||
stopovers: true
|
||
})
|
||
```
|
||
|
||
`journeys()` will resolve with an object with the following fields:
|
||
- `journeys`
|
||
- `earlierRef`/`laterRef` – pass them as `opt.earlierThan`/`opt.laterThan` into another `journeys()` call to retrieve the next "page" of journeys
|
||
- `realtimeDataUpdatedAt` – a UNIX timestamp reflecting the latest moment when (at least some of) the response's realtime data have been updated
|
||
|
||
This object might look like this:
|
||
|
||
```js

|

|
||
Some [profiles](../p) are able to parse the ticket information, if returned by the API. For example, if you pass `tickets: true` with the [VBB profile](../p/vbb), each `journey` will have a tickets array that looks like this:
|
||
|
||
```js
|
||
[ {
|
||
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`.
|
||
|
||
To get more journeys earlier/later than the current set of results, pass `earlierRef`/`laterRef` into `opt.earlierThan`/`opt.laterThan`. For example, query *later* journeys as follows:
|
||
|
||
```js
|
||
const hbf = '900000003201'
|
||
const heinrichHeineStr = '900000100008'
|
||
|
||
const res1 = await client.journeys(hbf, heinrichHeineStr)
|
||
const lastJourney = res1.journeys[res1.journeys.length - 1]
|
||
console.log('departure of last journey', lastJourney.legs[0].departure)
|
||
|
||
// get later journeys
|
||
const res2 = await client.journeys(hbf, heinrichHeineStr, {
|
||
laterThan: res1.laterRef
|
||
})
|
||
const firstLaterJourney = res2.journeys[res2.journeys.length - 1]
|
||
console.log('departure of first (later) journey', firstLaterJourney.legs[0].departure)
|
||
```
|
||
|
||
```
|
||
departure of last journey 2017-12-17T19:07:00+01:00
|
||
departure of first (later) journey 2017-12-17T19:19:00+01:00
|
||
```
|
||
|
||
If you pass `polylines: true`, each journey leg will have a `polyline` field. Refer to [the section in the `trip()` docs](trip.md#polyline-option) for details.
|
||
|
||
If you pass `scheduledDays: true`, each journey will have a `scheduledDays` object looking like this:
|
||
|
||
```js
|
||
{
|
||
'2018-01-01': true,
|
||
'2018-01-02': false,
|
||
// …
|
||
'2018-10-12': true,
|
||
'2018-10-13': true,
|
||
// …
|
||
'2019-01-02': false,
|
||
'2019-01-03': false
|
||
}
|
||
```
|
