elixir-protobuf/protobuf

This system is an Elixir library for Protocol Buffers (Protobuf) that handles binary, JSON, and text format encoding and decoding. It provides a code generator to produce Elixir modules from .proto files and includes utilities for Google standard types and message identification. The project also features a comprehensive test suite and a benchmarking suite for performance analysis.

How it got here

2017 · Initial project scaffolding and protoc code generation

This period established the foundational structure of the protobuf-elixir library, including initial project setup, configuration updates, and the introduction of JSON and text format support. It also introduced the protoc code generator and its associated EEx templates, enabling automatic Elixir module generation from .proto files.

2018–2020 · Protobuf standard types and JSON mapping

This period focused on expanding the library's capabilities by adding support for Google's standard Protobuf types and implementing JSON encoding/decoding. The team also established a comprehensive benchmarking suite to measure Protobuf performance, including automated dataset management and throughput testing scripts.

10 changes

2021–2024 · Protobuf conformance and DSL refactoring

This period focused on enhancing the library's correctness and structure by refactoring the Protobuf wire format and DSL generation into dedicated modules. The team also implemented a comprehensive conformance test suite to validate encoding and decoding behavior, alongside adding conversion helpers for Google Protobuf types.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit b0f59c2b2d — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
