Blekingetrafiken API for NodeJS

A fully async API written in ES6 for retrieval of public transport information, schedules and routes in Blekinge

---

Setting up

Installing

npm install blekingetrafiken

Quickstart

const api = require('blekingetrafiken');

// Fetch departures
api.fetchDepartures()
.then(departures => {
  const departure = departures[0];
  console.log(`A transportation of type '${departure.type}' (line ${departure.name}) is departing ${departure.onSchedule ? 'on schedule' : 'later than planned'} from stop point ${departure.stopPoint}`);
});

> A transportation of type 'Stadsbuss' (line 6) is departing on schedule from stop point A

Disclaimer

Although the project is very capable, it is not built with production in mind. Therefore there might be complications when trying to use the API for large-scale projects meant for the public. The API was created to easily fetch public transport information, schedules and routes in Blekinge programmatically and as such it might not promote best practices nor be performant. This project is not in any way affiliated with Blekingetrafiken or Blekinge.
