grpcc - A gRPC cli interface for easy testing against gRPC servers

•    Javascript

---

grpcc is a flexible command-line client for any gRPC server for quick and easy testing of APIs. grpcc is written in nodejs but can talk to a gRPC service written in any language. By default, grpcc will attempt to make a secure connection to the service. If you need an insecure connection, you can pass in the -i flag.

polyglot - A universal grpc command line client

•    Java

---

In particular, it is not necessary to generate grpc classes for the service or to compile the protos into the Polyglot binary. All you need to run Polyglot is a Java runtime. Binaries for Mac, Linux, and Windows are available from the releases page.

go-grpc-prometheus - Prometheus monitoring for your gRPC Go servers.

•    Go

---

Prometheus monitoring for your gRPC Go servers and clients. A sister implementation for gRPC Java (same metrics, same semantics) is in grpc-ecosystem/java-grpc-prometheus.

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.

nrpc - nRPC is like gRPC, but over NATS

•    Go

---

nRPC is an RPC framework like gRPC, but for NATS. It can generate a Go client and server from the same .proto file that you'd use to generate gRPC clients and servers. The server is generated as a NATS MsgHandler.

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.

grpc-gateway - gRPC to JSON proxy generator following the gRPC HTTP spec

•    Go

---

grpc-gateway is a plugin of protoc. It reads gRPC service definition, and generates a reverse-proxy server which translates a RESTful JSON API into gRPC. This server is generated according to the google.api.http annotation in your gRPC service definition. It helps you to provide your APIs in both gRPC and RESTful style at the same time.

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.

grpc-web - gRPC Web implementation for Golang and TypeScript

•    TypeScript

---

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).

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.

armeria - Asynchronous RPC/REST library built on top of Java 8, Netty, HTTP/2, Thrift and gRPC

•    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.

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

•    Java

---

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.

grpc-swift - The Swift language implementation of gRPC.

•    C

---

This repository contains an experimental Swift gRPC API and code generator.It is intended for use with Apple's swift-protobuf support for Protocol Buffers. Both projects contain code generation plugins for protoc, Google's Protocol Buffer compiler, and both contain libraries of supporting code that is needed to build and run the generated code.

go-microservice-helpers - A collection of handy snippets that simplify creation of GRPC servers and clients

•    Go

---

A collection of handy snippets that simplify creation of GRPC servers and clients. The provided helpers allow to create grpc endpoints with zipkin distributed tracing pre-configured; spawn http servers that serve both grpc and common http traffic; simplify golang crypto primitives to load EC keys.

grpc-proxy - gRPC proxy is a Go reverse proxy that allows for rich routing of gRPC calls with minimum overhead

•    Go

---

The project now exists as a proof of concept, with the key piece being the proxy package that is a generic gRPC reverse proxy handler. The package proxy contains a generic gRPC reverse proxy handler that allows a gRPC server to not know about registered handlers or their data types. Please consult the docs, here's an exaple usage.

go-grpc-middleware - Golang gRPC Middlewares: interceptor chaining, auth, logging, retries and more.

•    Go

---

gRPC Go Middleware: interceptors, helpers, utilities. gRPC Go recently acquired support for Interceptors, i.e. middleware that is executed either on the gRPC Server before the request is passed onto the user's application logic, or on the gRPC client either around the user call. It is a perfect way to implement common patterns: auth, logging, message, validation, retries or monitoring.

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.

bloomrpc - GUI Client for GRPC Services
