Source: https://dreamsofcode.io/courses/cli-apps-go

What will I learn?

As well as learning how to write Go code, you’ll also learn how to build command line applications ranging from simple CLI utilities, to full TUI applications, enough to rival even a web applications. Some of the concepts you’ll learn – Reading and Writing to Files and Streams – Dealing with input and output – Parsing Command Line flags – Advanced Go concepts such as concurrency – Testing your code to ensure correctness – Creating network applications – Building complex command based applications – Creating interactive text user interfaces – Working with data stores such as BadgerDB and Sqlite. – Distributing your application to others

What will we build?

Throughout this application, we’ll build a number of different command line applications such as: – A tool to count lines and words in a file – Command based tooling for generating git commit messages using the OpenAI API – A tool to compress and extract data using gzip – A command line tool for storing and retriving data from the command line

Is this course right for me?

If you’re looking to learn Go, or you want to learn to build your own command line applications, then this course is perfect for you. Go is one of the best languages to learn in 2025, enabling high productivity, and a modern development experience whilst maintaining type and memory safety.

Will this course be updated?

Yes! The benefit of doing video courses such as this is that I’m able to easily update them compared to YouTube, so as the Go programming language changes, I’ll be able to make sure that the information stays relevant and up to date.
