GORM is the most popular DB libraries for Go. It is a full-featured object-relational mapping library for Golang. GORM is a developer-friendly tool for converting data between incompatible type systems. It is specially designed to minimize the rewritten codes when switching between type systems. GORM provides SQL builders, RAW SQL, auto migration tools, Extendable plugins for customization. All the features in GORM come with its own tests so that developers can easily try something new without borking the whole system.

2. Gen

Gen tool generates code for you. The tools help to generate type aware code in particular which tries to alleviate the gap of lacking templates in Golang. With no runtime magic, annotates your types with a special comment and generate source files.

3. Goose

Managing the schema is the primary task when working on relational databases. In some organizations, modifying the DB schema is considered a daunting experience. Goose packages allow the developers to easily perform schema changes and data migrations if required. It works by versioning the schema, using migration files corresponding to each schema. The migrations files can be SQL or Go commands.

4. cli

cli is a simple and fast package for building command-line apps for Golang. It allows the developers to develop their own expressive command-line apps. cli is used for creating flags, bash-completion routines and generates help texts. cli is fast, fun and playful when you code for an API.

5. Go Kit

Go Kit is GitHub’s most popular standard library for Go related Microservice. This library offers specialized support for microservices. Go kit addresses the gap between functions such as RPC safety, infrastructure integration, system observability, and program design. It also provides guidance for building distributed systems with a solution to common problems.

6. Vegeta

Vegeta is a tool used for HTTP load testing. This versatile tool was specially designed for testing HTTP services with a constant request rate. It works efficiently on analyzing the weak points of the program. Vegeta is one of the libraries that work throughout to improve the overall performance. It is presumably named after the Saiyan prince for its attack both targeted and distributed functions as a load tester.

7. Authboss

It has the support of GridFS and Failover managements. Another main advantage, it is fast and actively maintained with authentication support for pooling integration.

14. NSQ

NSQ is a robust distributed queue. It is primarily used for a building block for large scale distributed systems. It is a simple TCP protocol that supports client libraries in any language.
