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.

• Play with Go’s build tool and do workspace layouts, test and race detection, and more
• Learn how slices are implemented and how to think about them
• Unravel how Go handles garbage collection and reduction
• Deep-dive into Go’s methods, method values, and interfaces
• Learn how Go interfaces provide powerful ways to mock parts of code for unit testing
• Discover how to optimize code for speed by using the Go profiler
• Review Go's packages for dealing with databases, including interfacing to SQLite
