GTFS Realtime bindings generator for Node.js (adapted from Google’s old npm package)

Node.js GTFS Realtime Bindings

This package is based on Google’s older gtfs-realtime-bindings and is now supported by Cyberscape

This package provides JavaScript classes generated from the GTFS Realtime Protocol Buffer specification. These classes will allow you to parse a binary Protocol Buffer GTFS Realtime data feed into JavaScript objects.

We use the protobuf.js library for JavaScript Protocol Buffer support.

Install

To use the gtfs-rb classes in your own project, you need to first install our Node.js npm package:

npm install gtfs-rb

Example Code

See the examples

Note

For more details on the naming conventions for the Javascript classes generated from the gtfs-realtime.proto, check out the protobuf.js project which we use to handle our Protocol Buffer serialization.

gtfs-rb's Issues

Cannot read property 'decode' of undefined

When attempting to use gtfs-rb, on this line: let feed = GtfsRealtimeBindings.FeedMessage.decode(body);, I get the error TypeError: Cannot read property 'decode' of undefined. This actually wasn't happening with the other repo, but I was getting null values for important information with that one.
