vbb-hafas

A client for the Berlin & Brandenburg public transport service (VBB). It acts as a consistent and straightforward interface on top of a verbose API.

This project is actually a thin wrapper around hafas-client@6. Its docs document the API in general.

Note: You may not want to query the VBB API by yourself. vbb-client is an API-compatible client for vbb-rest, my wrapper API. It also works in the browser.

Installing

npm install vbb-hafas

API

Check the docs for hafas-client as well as its VBB-specific customisations.

Usage

const createHafas = require('vbb-hafas')

const hafas = createHafas('my-awesome-program')

As an example, we will search for a journey from Berlin Hauptbahnhof to Berlin Charlottenburg. To get the station IDs, use vbb-stations.

hafas.journeys('900000003201', '900000024101', {results: 1})
.then((journeys) => console.log(journeys[0]))
.catch(console.error)

The output will be an array of journey objects in the Friendly Public Transport Format 1.2.1 format:

Transfer information for journeys

vbb-hafas will try to add transfer information from vbb-change-positions if you pass transferInfo: true as an option.

If it identifies a known transfer, the previous leg will have a bestArrivalPosition and the next leg will have a departurePosition, indicating the optimal transfer between both platforms. Check out the markup in vbb-change-positions for more details.
