Course description

No one has put more effort into studying, describing, and explaining the principles of creating high-quality command-line interface (CLI) applications in Go than the author of this course, Marian. Go is not just about HTTP servers, and Marian demonstrates this like no one else. She is the author of the bestseller *Building Modern CLI Applications with Go* (available on Amazon) and has spoken twice at Gophercon, where she shared her deep experience in developing elegant and idiomatic CLI applications in Go.

Now, for the first time, Marian is ready to share all her accumulated experience in the format of a video course.

  • Over 5 hours of material.
  • No CLI experience required: the training starts with the basics and progresses to advanced topics. Only programming experience in Go is needed.
  • Step-by-step practical assignments at each stage.
