vbb-stations-autocomplete

vbb-stations-autocomplete provides a stations search for the Berlin Brandenburg public transport service (VBB). It pulls its data from vbb-stations.

Note: Because there are ~ 13k stations, this module contains ~ 800k of data (~ 240k gzipped).

Installing

npm install vbb-stations-autocomplete

Usage

autocomplete(query, results = 3, fuzzy = false, completion = true)

const autocomplete = require('vbb-stations-autocomplete')
autocomplete('Seestr', 3)

This returns stations in a reduced form of the Friendly Public Transport Format. To get all details, pass each id into vbb-stations.

If you set fuzzy to true, words with a Levenshtein distance <= 3 will be taken into account. This is a lot slower though:

test	performance
non-fuzzy – U mehringdamm	325 ops/sec
fuzzy – U mehrigndamm	73 ops/sec

Setting completion to false speeds things up a lot:

test	performance
completion – U friedr	306 ops/sec
no completion – U friedr	5076 ops/sec
