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.

ratelimit - Go/gRPC service designed to enable generic rate limit scenarios from different types of applications

•    Go

---

The rate limit service is a Go/gRPC service designed to enable generic rate limit scenarios from different types of applications. Applications request a rate limit decision based on a domain and a set of descriptors. The service reads the configuration from disk via runtime, composes a cache key, and talks to the Redis cache. A decision is then returned to the caller. Envoy's data-plane-api defines a ratelimit service proto rls.proto. Logically the data-plane-api rls is equivalent to the ratelimit.proto defined in this repo. However, due to the namespace differences and how gRPC routing works it is not possible to transparently route the legacy ratelimit (ones based in the ratelimit.proto defined in this repo) requests to the data-plane-api definitions. Therefore, the ratelimit service will upgrade the requests, process them internally as it would process a data-plane-api ratelimit request, and then downgrade the response to send back to the client. This means that, for a slight performance hit for clients using the legacy proto, ratelimit is backwards compatible with the legacy proto.

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.

---

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.

Fortio - Load testing library, command line tool, advanced echo server and web UI in Go

•    Go

---

Fortio (Φορτίο) started as, and is, Istio's load testing tool and now graduated to be its own project. Fortio runs at a specified query per second (qps) and records an histogram of execution time and calculates percentiles (e.g. p99 ie the response time such as 99% of the requests take less than that number (in seconds, SI unit)). It can run for a set duration, for a fixed number of calls, or until interrupted (at a constant target QPS, or max speed/load per connection/thread).

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.

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).

karate - Test Automation Made Simple

•    Java

---

Karate is the only open-source tool to combine API test-automation, mocks, performance-testing and even UI automation into a single, unified framework. The BDD syntax popularized by Cucumber is language-neutral, and easy for even non-programmers. Assertions and HTML reports are built-in, and you can run tests in parallel for speed.

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.

gripmock - gRPC Mock Server

•    Go

---

GripMock is a mock server for GRPC services. It's using a .proto file to generate implementation of gRPC service for you. If you are already familiar with Apiary or WireMock for mocking API service and looking for similiar thing for GRPC then this is the perfect fit for that. Matched stub will be returned to GRPC service then further parse it to response the rpc call.

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.

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.

hyperf - 🚀 A coroutine framework that focuses on hyperspeed and flexibility

•    PHP

---

Hyperf is an extremely performant and flexible PHP CLI framework based on Swoole 4.5+, powered by the state-of-the-art coroutine server and a large number of battle-tested components. Aside from the decisive benchmark outmatching against PHP-FPM frameworks, Hyperf also distinct itself by its focus on flexibility and composability. Hyperf ships with an AOP-enabling dependency injector to ensure components and classes are pluggable and meta programmable. All of its core components strictly follow the PSR standards and thus can be used in other frameworks. Hyperf's architecture is built upon the combination of Coroutine, Dependency injection, Events, Annotation, AOP (aspect-oriented programming). Core components provided by Hyperf can be used out of the box in coroutine context. The set includes but not limited to: MySQL coroutine client, Redis coroutine client, WebSocket server and client, JSON RPC server and client, gRPC server and client, Zipkin/Jaeger (OpenTracing) client, Guzzle HTTP client, Elasticsearch client, Consul client, ETCD client, AMQP component, Apollo configuration center, Aliyun ACM, ETCD configuration center, Token bucket algorithm-based limiter, Universal connection pool, Circuit breaker, Swagger, Swoole Tracker, Snowflake, Simply Redis MQ, RabbitMQ, NSQ, Nats, Seconds level crontab, Custom Processes, etc. Be assured Hyperf is still a PHP framework. You will also find familiar packages such as Middleware, Event Manager, Coroutine optimized Eloquent ORM (And Model Cache!), Translation, Validation, View engine (Blade/Smarty/Twig/Plates/ThinkTemplate) and more at your command.
