or
$ yarn add dvbjs

and require it in your project

import * as dvb from "dvbjs";

HTTP request are handled by axios that supports all modern browsers. See packages/react-example for a browser departure monitor example.

Example Usage

Find stops by name

import * as dvb from "dvbjs"; // OR const dvb = require("dvbjs");

dvb.findStop("zellesch").then((data) => {
  console.dir({ data }, { depth: 7, maxArrayLength: 2 });
});
{
  data: [
    {
      city: 'Dresden',
      coords: [ 13.745859050200034, 51.0283698098441 ],
      name: 'Zellescher Weg',
      id: '33000312',
      type: 'Stop'
    },
    {
      city: 'Clausthal-Zellerfeld',
      coords: [ 10.347333308428196, 51.80899839555576 ],
      name: 'Eschenbacher Stra├če',
      id: '26005221',
      type: 'Stop'
    }
  ]
}

Monitor a single stop

import * as dvb from "dvbjs"; // OR const dvb = require("dvbjs");

const stopID = "33000037"; // Postplatz
const timeOffset = 5;
const numResults = 2;

dvb.monitor(stopID, timeOffset, numResults).then((data) => {
  console.dir(data, { depth: 7, maxArrayLength: 2 });
});
