RESTful Go APIs

Building fast, secure, and idiomatic Go REST APIs

Topic: Web & Mobile
Mofi Rahman

If you’ve been around the internet for a while, you’ve probably interacted with REST APIs in some form or another. A major portion of the internet works on REST APIs. Most modern languages support creating REST APIs, and Go in particular is an excellent choice for building modern RESTful web APIs. It’s fast, compiled, and easy to use—and, most importantly, supports developer productivity.

Join expert Mofi Rahman to learn how to build fast, scalable REST APIs with Go. You’ll explore what REST APIs are, dive into Go libraries and frameworks for building REST APIs, and more.

What you'll learn-and how you can apply it

By the end of this live online course, you’ll understand:

  • What REST APIs are
  • Why you should use Go for building REST APIs

And you’ll be able to:

  • Use Go for your next web application
  • Build REST APIs for your application

This training course is for you because...

  • You’re a developer.
  • You want to build REST APIs.
  • You want to use Go for building microservices.

Prerequisites

  • A computer with Go 1.13+ installed and configured (Optional: Install an editor with Go support—VS Code + the Go extension, for example.)
  • A working knowledge of Go
  • Familiarity working in a terminal
