• uuid

  18 5,006 7.1 Go

  Go package for UUIDs based on RFC 4122 and DCE 1.1: Authentication and Security Services. (by google)

  

👍 I recommend to use the google/uuid package to create unique IDs, because this is a more versatile way to protect your application against common number brute force attacks. Especially if your REST API will have public methods without authorization and request limit.

• Testify

  64 22,019 8.6 Go

  Swagger UI is a collection of HTML, JavaScript, and CSS assets that dynamically generate beautiful documentation from a Swagger-compliant API.

  

As you can guess from the title, we're not going to worry too much about documenting our API methods. Simply because there is a great tool like Swagger that will do all the work for us!
