hafas-client

A client for HAFAS public transport APIs. Sort of like public-transport-enabler, but with a smaller scope. It contains customisations for the following transport networks:

Background

There's a company called HaCon that sells a public transport management system called HAFAS. It is used by companies all over Europe to serve routing and departure information for apps. All those endpoints are similar, with the same terms and API routes, but have slightly different options, filters and sets of enabled features.

hafas-client contains all logic for communicating with these, as well as serialising from and parsing to Friendly Public Transport Format (FPTF) 1.1.1. Endpoint-specific customisations (called profiles here) increase the quality of the returned data.

Installing

npm install hafas-client

hafas-client as well its dependencies use Node-builtin modules and Node globals. To be able to use it within react-native, follow the instructions at node-libs-react-native.

API documentation

Usage

const createClient = require('hafas-client')
const dbProfile = require('hafas-client/p/db')

// create a client with Deutsche Bahn profile
const client = createClient(dbProfile, 'my-awesome-program')

// Berlin Jungfernheide to München Hbf
client.journeys('8011167', '8000261', {results: 1})
.then(console.log)
.catch(console.error)

The returned Promise will resolve with an array of one FPTF journey.
