O'Reilly - Intermediate Go Programming

Designed for programmers familiar with the basics of Go, this course is an information-rich followup to Introduction to Go Programming. After a quick review of the basic Go syntax—with an emphasis on tricky areas and less common usage—expert programmer John Graham-Cumming delves into Go's build tool and more complex uses of slices, channels, goroutines, interfaces, and methods.

The video shows how to build a simple JSON API that talks to a database, and how to build a flexible system for using goroutines to do work concurrently. Tips on how to write idiomatic Go, vendoring, and mocking for unit tests are also covered.
