Language bindings generated from the GTFS-realtime protocol buffer spec for popular languages.

GTFS-realtime is a data format for communicating real-time information about public transit systems. GTFS-realtime data is encoded and decoded using Protocol Buffers, a compact binary representation designed for fast and efficient processing. The data schema itself is defined in gtfs-realtime.proto.

To work with GTFS-realtime data, a developer would typically use the gtfs-realtime.proto schema to generate classes in the programming language of their choice. These classes can then be used for constructing GTFS-realtime data model objects and serializing them as binary data or, in the reverse direction, parsing binary data into data model objects.

Because generating GTFS-realtime data model classes from the gtfs-realtime.proto schema is such a common task, but also one that sometimes causes confusion for first-time developers, this project aims to provide pre-generated GTFS-realtime language bindings for a number of the most popular programming languages. Where possible, these language bindings will be published as packages to facilitate their use in other projects.

• .NET
• Java
• JavaScript / Node.js
• PHP
• Python
• Ruby
• Golang

We don't provide generated code for C++, use the official protoc compiler for that (from here or here)
