Client for the LVB (Leipziger Verkehrsbetriebe) API. Inofficial, please ask LVB for permission before using this module in production. Actually, there should be no need for projects like this since municipal public transportation endpoints should be open to the public. It's 2017.
npm install --save lvbThis package mostly returns data in the Friendly Public Transport Format:
stations(query, [opt])- Search for stationsdepartures(station, date = Date.now())- Departures at a given stationjourneys(origin, destination, date = Date.now(), [opt])- Search for journeys between stations
Using lvb.stations, you can query stations operated bei LVB.
const stations = require('lvb').stations
stations('Nationalbibliothek').then(console.log)Returns a Promise that will resolve in an array of stations in the Friendly Public Transport Format which looks as follows:
[
{
"id": "11558",
"type": "station",
"name": "Leipzig, Deutsche Nationalbibliothek",
"coordinates": {
"longitude": 12.396131411662,
"latitude": 51.323542325868
}
}
// …
]defaults, partially overridden by the opt parameter, looks as follows:
const defaults = {
limit: 5 // Maximum number of returned results. CAUTION: Because of something unlucky that happens to station ids in the API, a `stations` request will spawn (number of results + 1) requests. Keep this in mind when increasing this threshold.
}Using lvb.departures, you can get departures at a given station for a specific date and time.
const departures = require('lvb').departures
const Nationalbibliothek = '11558'
departures(Nationalbibliothek, new Date())Returns a Promise that will resolve in a list of objects (one object per direction per line) like this:
[
{
"line": {
"id": "16",
"name": "Str 16", // yeah, that really looks like this :/
"class": "StN",
"operator": "LVB",
"direction": "Lößnig über Connewitz, Kreuz"

}
]
}
// …
]Using lvb.journeys, you can get directions and prices for routes from A to B.
const journeys = require('lvb').journeys
journeys(origin, destination, date = Date.now(), opt = defaults)
const Nationalbibliothek = '11558'
const Messe = '10818'
const date = new Date()
journeys(Nationalbibliothek, Messe, date)
.then(console.log)
.catch(console.error)Returns a Promise that will resolve with an array of journeys in the Friendly Public Transport Format which looks as follows.
Note that the legs are not (fully) spec-compatible, as the schedule is missing (see the line and route keys instead).
