db-hafas

A client for the German Railways (DB). 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.

Getting Started

import {createDbHafas} from 'db-hafas'

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

As an example, we will search for a route from Berlin Jungfernheide to München Hbf. To get the station IDs, use locations(query, [opt]).

// Berlin Jungfernheide to München Hbf
const {journeys} = await hafas.journeys('8011167', '8000261', {
	results: 1,
})
console.log(journeys[0])

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