Golang offers a superb standard library with a set of core packages that enhance and extend the language. It's very helpful to build pretty much everything. However, there are a lot of other tools to help build Go backends, microservices, low-code platforms, and more. Here are a few examples:
Gin – The Gin micro-framework is a powerful tool for building web applications and microservices. Gin was designed to reduce the boilerplate code involved in building these types of applications. It's also useful for creating reusable and extensible code.
Web.go – Because of its tree routing system, it's considered the lightest and simplest Go framework available. Web.go is the best fit for projects that require routing.
Gocraft – Programmers love this Go web framework because it helps them develop additional web application features. Excellent for developing highly scalable applications.
Gorilla – A set of reusable components that come with a web/HTTP library. Gorilla is one of the biggest and most efficient frameworks around as it provides new extensions, modules, and drop packages.
Revel – One of the largest and most popular Golang frameworks. Self-sufficient and unbound to middleware or third-party plugins, you don't have to set it up or configure Revel. This framework is all you need to develop application programming interfaces (APIs).
GORM – A Golang library for converting data between incompatible systems and minimising the need for rewritten code. This library offers auto migration tools, SQL builders, RAW SQL, and extendable plugins for customisation.
Go Kit – This library for building microservices offers specialised support for microservices in addition to improved remote procedure call (RPC) safety, infrastructure integration, program design, guidance for building distributed systems, and more.
Authboss – A Golang library and a modular web authentication system, Authboss provides several easy-to-integrate authentication and authorisation modules.
Golang startup kit – An open-source set of boilerplate code and libraries for building SaaS applications.
