About the Book

The book teaches you how to write web applications in Go without using a framework. It is possible to write a webapp without using any framework in Go. Each new concept will be explained via a valid code example. The book is based of a todo list manager I wrote in Go, and at any point in time, you can check the source code of the todo list manager.
