db-prices

JavaScript module for finding the cheapest railway connections using the Deutsche Bahn Sparpreise API. Inofficial, using an endpoint by Deutsche Bahn. Ask them for permission before using this module in production.

Installation

npm install db-prices

Usage

prices() returns a Promise that will resolve with a list of offers.

const prices = require('db-prices')

prices(from, to, [date], [opt]).then(…)

from and to must be station IDs like '8000105'. date must be a Date object; if empty, the current datetime will be used.

With opt, you can override the default options, which look like this:

{
	class: 			2, 	// 1st class or 2nd class
	noICETrains: 		false,
	transferTime: 		0, 	// in minutes
	duration: 		1440, 	// search for routes in the next n minutes
	preferFastRoutes: 	true,
	travellers: [{ 		// one or more
		bc:	0, 	// BahnCard ID (see https://gist.github.com/juliuste/202bb04f450a79f8fa12a2ec3abcd72d)
		typ: 	"E", 	// E: adult: K: child; B: baby -- BUG: child and baby dont work ATM
		alter: 	30 	// age
	}],
}

Response

The result will be a list of Friendly Public Transport Format journey objects.

With from = '8000105', to = '8011160' and date = new Date('2016-08-17T00:00:00.000Z'), the result looked like this:
