Protocol Buffers - Google's data interchange format

  •        95

Protocol buffers (a.k.a., protobuf) are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages.

protobuf-c - Protocol Buffers implementation in C

  •    C++

This is protobuf-c, a C implementation of the Google Protocol Buffers data serialization format. It includes libprotobuf-c, a pure C library that implements protobuf encoding and decoding, and protoc-c, a code generator that converts Protocol Buffer .proto files to C descriptor code, based on the original protoc. protobuf-c formerly included an RPC implementation; that code has been split out into the protobuf-c-rpc project. protobuf-c's mailing list is hosted on a Google Groups forum.

An implementation of Protocol Buffers in Swift. Protocol Buffers are a way of encoding structured data in an efficient yet extensible format. This project is based on an implementation of Protocol Buffers from Google. See the Google protobuf project for more information.

php-protobuf - PHP Protobuf - Google's Protocol Buffers for PHP

  •    PHP

Protocol Buffers are a way of encoding structured data in an efficient yet extensible format. It might be used in file formats and RPC protocols.PHP Protobuf is Google's Protocol Buffers implementation for PHP with a goal to provide high performance, including a protoc plugin to generate PHP classes from .proto files. The heavy-lifting (a parsing and a serialization) is done by a PHP extension.

prototool - Your Swiss Army Knife for Protocol Buffers

  •    Go

Protobuf is one of the best interface description languages out there - it's widely adopted, and after over 15 years of use, it's practically bulletproof. However, working with Protobuf and maintaining consistency across your Protobuf files can be a pain - protoc, while being a tool that has stood the test of time, is non-trivial to use, and the Protobuf community has not developed common standards with regards to stub generation. Prototool aims to solve this by making working with Protobuf much simpler. Prototool accomplishes this by downloading and calling protoc on the fly for you, handing error messages from protoc and your plugins, and using the generated FileDescriptorSets for internal functionality, as well as wrapping a few great external libraries already in the Protobuf ecosystem.

ScalaBuff - the scala protocol buffers (protobuf) compiler

  •    Scala

ScalaBuff is a Scala Protocol Buffers (protobuf) compiler. It takes .proto files and outputs valid Scala classes that can be used by your code to receive or send protobuf messages. Both the ScalaBuff generator and the generated Scala classes depend on Google's Java runtime for Protocol Buffers, which is provided with ScalaBuff.

swift-protobuf - Plugin and runtime library for using protobuf with Swift

  •    Swift

Apple's Swift programming language is a perfect complement to Google's Protocol Buffer ("protobuf") serialization technology. They both emphasize high performance and programmer safety. This project provides both the command-line program that adds Swift code generation to Google's protoc and the runtime library that is necessary for using the generated code. After using the protoc plugin to generate Swift code from your .proto files, you will need to add this library to your project.

protoc-gen-doc - Documentation generator plugin for Google Protocol Buffers

  •    Go

This is a documentation generator plugin for the Google Protocol Buffers compiler (protoc). The plugin can generate HTML, JSON, DocBook and Markdown documentation from comments in your .proto files. It supports proto2 and proto3, and can handle having both in the same context (see examples for proof).

This repository contains a protoc plugin that generates TypeScript declarations (.d.ts files) that match the JavaScript output of protoc --js_out=import_style=commonjs,binary. This plugin can also output service definitions as both .js and .d.ts files in the structure required by grpc-web. This plugin is tested and written using TypeScript 2.7.

rust-protobuf - Rust implementation of Google protocol buffers

  •    Rust

Protobuf implementation in Rust. 1.7+ 2.* versions should follow semver conventions. However, if you are developing critical library it's probably better to specify version as ~2.0 (>= 2.0 and <= 2.1), but not as 2.0 (>= 2.0 and <= 3.0).

protocol-buffers - Protocol Buffers for Node.js

  •    Javascript

See the Google Protocol Buffers docs for more information about the available types etc.Since v4 you can now compile your schemas to a JavaScript file you can require from Node. This means you do not have runtime parse the schemas, which is useful if using in the browser or on embedded devices. It also makes the dependency footprint a lot smaller.

Wire - Clean, lightweight protocol buffers for Android and Java.

Schemas describe and document data models. If you have data, you should have a schema. Google's Protocol Buffers are built around a great schema language. It's cross platform and language independent. Whatever programming language you use, you'll be able to use proto schemas with your application. Proto schemas are backwards-compatible and future-proof. You can evolve your schema as your application loses old features and gains new ones.

pbf - A low-level, lightweight protocol buffers implementation in JavaScript.

A low-level, fast, ultra-lightweight (3KB gzipped) JavaScript library for decoding and encoding protocol buffers, a compact binary format for structured data serialization. Works both in Node and the browser. Supports lazy decoding and detailed customization of the reading/writing code.If you use webpack as your module bundler, you can use pbf-loader to load .proto files directly. It returns a compiled module ready to be used.

duplex - Full duplex modern RPC

  •    Python

Duplex is an RPC protocol designed for dynamic (and some statically-typed) languages that focuses on advanced RPC semantics and not object or frame serialization. This lets you pick how to marshal objects, whether with JSON, msgpack, protobuf, BERT, BSON, or anything custom.While that alone is somehow already revolutionary for RPC protocols, it also combines client and server into a peer object, letting either side of the connection call or provide invocable service methods. This means you never have to worry about only having a client or only having a server library in your language. It also allows for flexible connection topologies (server calling client functions), callbacks, and plugin architectures.
