GTFS-PARSER ⚠️Work In Progress

The GTFS-PARSER library is supposed to be a simple way to parse GTFS zip files from urls. It should be able to handle reading zip files without taking up space on your harddrive and convert the text files to json array's based on the GTFS specification. It takes the liberty of converting non-string fields over to integers, but by default the csvtojson library used under the hood will convert everything to strings.

Getting Started

To get started you will first need to define where the zip file is located and then the gtfs.init() method needs to be run to fetch the file.

const url =
  "https://raw.githubusercontent.com/AvidDabbler/gtfs-parser/main/test/pts_google_transit.zip";

const gtfs = new Gtfs(url);
await gtfs.init();

Methods

After the gtfs.init() is run you can then access the methods in the Gtfs class.

fileParser

If you are wanting to just parse one of the files as just an array of objects you can just use the await gtfs.fileParser(fileName: string) method.

Arguements

• fileName - this arguement is just a string of the file name in relation to the files in the gtfs. So if you are interested in the agencies file you would just use await gtfs.fileParser('agency.txt')

tripsToGeojson

Using the gtfs.tripsToGeojson() will build and return the trips geometries and properties from the gtfs as geojson.

routesToGeojson

Using the gtfs.routesToGeojson() will build and return the routes geometries and properties from the gtfs as geojson.

stopsToGeojson

Using gtfs.stopsToGeojson() will build and return the stops geometries and properties from the gtfs as geojson.
