Thanks for giving this book a chance! This book is a guide that takes you through the possibilities of the Go standard library, which has a lot of out-of-the-box functionality and solutions. Note that the solutions covered in the book are mainly simple demonstrations of how the standard library implementation is used and how it works. These recipes are meant to provide a starting point for you to work out how to solve your specific problem rather than solve the problem completely.

This book is for those who want to strengthen the basics and reveal hidden parts of the Go standard library. The book expects readers to have the elementary knowledge of Go. For some recipes, a basic understanding of HTML, operating systems, and networking will be helpful.

, Interacting with the Environment , explores how your code can interact with the operating system environment. The use of command-line flags and arguments, consuming signals, and working with child processes are also covered.

, Strings and Things , goes through common operations on strings, from simple searching for substrings to formatting text to tabs.

, Dealing with Numbers , sheds light on basic conversions and number formatting options. Operations with large numbers and the correct use of plurals within output messages are covered.

, Once Upon a Time , puts the time package under the magnifying glass and covers formatting, arithmetics, and running code for given time period or after a certain delay.

, In and Out , covers I/O operations that utilize standard Go interfaces. Besides the basic I/O, the chapter also covers some useful serialization formats and how to handle them.

, Discover the Filesystem , discusses working with the filesystem, including listing the folders, reading and changing the file attributes, and comparing files side by side.

, Connect the Network , showcases the client-side implementations for connecting the TCP and UDP server, along with the use of SMTP, HTTP, and JSON-RPC .

, Working with Databases , focuses on common database tasks such as data selection and extraction, transaction handling and execution, and the shortcomings of stored procedures.

, Come to the Server Side , provides a view on networking from the server's perspective. TCP, UDP, and HTTP server basics are presented.
