gRPC-Java - The Java gRPC implementation. HTTP/2 based RPC

  •        27

In gRPC a client application can directly call methods on a server application on a different machine as if it was a local object, making it easier for you to create distributed applications and services. As in many RPC systems, gRPC is based around the idea of defining a service, specifying the methods that can be called remotely with their parameters and return types.

ts-protoc-gen - Protocol Buffers Compiler (protoc) plugin for TypeScript and gRPC-Web.

  •    TypeScript

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.

gRPC-Web is a cutting-edge spec that enables invoking gRPC services from modern browsers. If you are looking for gRPC support for Node.js there is an official Node.js gRPC library. This package supports Node.js, but requires that the server has the gRPC-Web compatibility layer (read on to understand more).

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.

  •    Java

Visit the official web site for more information.Armeria is an open-source asynchronous RPC/API client/server library built on top of Java 8, Netty 4.1, HTTP/2, Thrift and gRPC. Its primary goal is to help engineers build high-performance asynchronous microservices that use HTTP/2 as a session layer protocol.

twirp - A simple RPC framework with protobuf service definitions

  •    Go

Twirp is a framework for service-to-service communication emphasizing simplicity and minimalism. It generates routing and serialization from API definition files and lets you focus on your application's logic instead of thinking about folderol like HTTP methods and paths and JSON. For more on the motivation behind Twirp (and a comparison to REST APIs and gRPC), the announcement blog post is a good read.

go-micro-services - HTTP up front, Protobufs in the rear

  •    Go

An demonstration of Golang micro-services that expose a HTTP/JSON frontend and then leverages gRPC for inter-service communication. The web page makes an HTTP request to the API Endpoint which in turn spawns a number of RPC requests to the backend services.

rejoiner - Generates a unified GraphQL schema from gRPC microservices and other Protobuf sources

These features are actively being developed.SchemaModule is a Guice module that is used to generate parts of a GraphQL schema. It finds methods and fields that have Rejoiner annotations when it's instantiated. It then looks at the parameters and return type of these methods in order to generate the appropriate GraphQL schema. Examples of queries, mutations, and schema modifications are presented below.

grpcurl - Like cURL, but for gRPC: Command-line tool for interacting with gRPC servers

  •    Go

grpcurl is a command-line tool that lets you interact with gRPC servers. It's basically curl for gRPC servers. The main purpose for this tool is to invoke RPC methods on a gRPC server from the command-line. gRPC servers use a binary encoding on the wire (protocol buffers, or "protobufs" for short). So they are basically impossible to interact with using regular curl (and older versions of curl that do not support HTTP/2 are of course non-starters). This program accepts messages using JSON encoding, which is much more friendly for both humans and scripts.

colossus - Colossus — An example microservice architecture for Kubernetes using Bazel, Go, Java, Docker, Kubernetes, Minikube, Gazelle, gRPC, Prometheus, Grafana, and more

  •    Python

Wait a second, these services don't do anything meaningful! Nope, they sure don't. But that's okay because the point of this project is to show you how to get the basic (yet not-at-all-trivial) plumbing to work. Colossus is a boilerplate project that's meant as a springboard to more complex and meaningful projects. Getting all of these technologies to work together was a real challenge. I had to dig through countless GitHub issues and dozens of example projects to make all these things work together. I'm offering this repo as a starter pack for other people with a Bazel monorepo targeting Kubernetes.

cilium - HTTP, gRPC, and Kafka Aware Security and Networking for Containers with BPF and XDP

  •    Go

Cilium is open source software for providing and transparently securing network connectivity and loadbalancing between application workloads such as application containers or processes. Cilium operates at Layer 3/4 to provide traditional networking and security services as well as Layer 7 to protect and secure use of modern application protocols such as HTTP, gRPC and Kafka. Cilium is integrated into common orchestration frameworks such as Kubernetes and Mesos. A new Linux kernel technology called BPF is at the foundation of Cilium. It supports dynamic insertion of BPF bytecode into the Linux kernel at various integration points such as: network IO, application sockets, and tracepoints to implement security, networking and visibility logic. BPF is highly efficient and flexible. To learn more about BPF, read more in our extensive BPF and XDP Reference Guide.

doorman - Doorman: Global Distributed Client Side Rate Limiting.

  •    Go

Doorman is a solution for Global Distributed Client Side Rate Limiting. Clients that talk to a shared resource (such as a database, a gRPC service, a RESTful API, or whatever) can use Doorman to voluntarily limit their use (usually in requests per second) of the resource. Doorman is written in Go and uses gRPC as its communication protocol. For some high-availability features it needs a distributed lock manager. We currently support etcd, but it should be relatively simple to make it use Zookeeper instead.The Doorman master server remembers all clients that currently have capacity and whenever a client asks for capacity it inserts the clients request into its memory and runs the algorithm to figure out what this client should get.

The purpose of this repository is to have a single place for people to push code and various documentation that gravitate around experimenting with new features for gRPC. This repository isn't tested, and will be lightly curated, so the code here should not be considered production-worthy (and it may not be functional at all).Some of the experiments conducted here might be cherry-picked for being introduced as an actual pull request on our main repositories.
