chi is a lightweight, idiomatic and composable router for building Go 1.7+ HTTP services. It's especially good at helping you write large REST API services that are kept maintainable as your project grows and changes. chi is built on the new context package introduced in Go 1.7 to handle signaling, cancelation and request-scoped values across a handler chain. 
The focus of the project has been to seek out an elegant and comfortable design for writing REST API servers, written during the development of the Pressly API service that powers our public API service, which in turn powers all of our client-side applications.

A progressive Node.js framework for building efficient and scalable server-side applications, heavily inspired by Angular. Nest is a framework for building efficient, scalable Node.js server-side applications. It uses modern JavaScript, is built with TypeScript (preserves compatibility with pure JavaScript) and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming).
 
Nest provides a level of abstraction above these common Node.js frameworks (Express/Fastify), but also exposes their APIs directly to the developer. This allows developers the freedom to use the myriad of third-party modules which are available for the underlying platform.

Dapr is a portable, serverless, event-driven runtime that makes it easy for developers to build resilient, stateless and stateful microservices that run on the cloud and edge and embraces the diversity of languages and developer frameworks. Dapr codifies the best practices for building microservice applications into open, independent, building blocks that enable you to build portable applications with the language and framework of your choice. Each building block is independent and you can use one, some, or all of them in your application.

Go kit is a programming toolkit for building microservices (or elegant monoliths) in Go. We solve common problems in distributed systems and application architecture so you can focus on delivering business value. Go is a great general-purpose language, but microservices require a certain amount of specialized support. RPC safety, system observability, infrastructure integration, even program design — Go kit fills in the gaps left by the standard library, and makes Go a first-class language for writing microservices in any organization.
 
Go has emerged as the language of the server, but it remains underrepresented in so-called "modern enterprise" companies like Facebook, Twitter, Netflix, and SoundCloud. Many of these organizations have turned to JVM-based stacks for their business logic, owing in large part to libraries and ecosystems that directly support their microservice architectures.
 
To reach its next level of success, Go needs more than simple primitives and idioms. It needs a comprehensive toolkit, for coherent distributed programming in the large. Go kit is a set of packages and best practices, which provide a comprehensive, robust, and trustable way of building microservices for organizations of any size.

Resgate is a Go project implementing a realtime API gateway for the RES protocol with NATS server as messaging system. It is a simple server that lets you create REST, real time, and RPC APIs, where all your clients are synchronized seamlessly.
 
Resgate handles all API requests from your clients, instead of directly exposing your micro-services (represented by Node.js and Java below). Clients will connect to Resgate, using either HTTP or WebSocket, to make requests. These requests are sent to the micro-services over NATS server, and Resgate will keep track on which resource each client has requested. Whenever there is a change to the data, the responsible micro-service sends an event. Resgate will use this event to both update its own cache, and make sure each subscribing client is kept up-to-date.

 Hexagon is a microservices library written in Kotlin. Its purpose is to ease the building of services (Web applications, APIs or queue consumers) that run inside a cloud platform. It is meant to provide abstraction from underlying technologies to be able to change them with minimum impact. It is designed to fit in applications that conforms to the Hexagonal Architecture (also called Clean Architecture or Ports and Adapters Architecture).
