Go Standard Library Cookbook (ePub)

Implement solutions by leveraging the power of the GO standard library and reducing dependency on external crates

Key Features

• Develop high quality, fast and portable applications by leveraging the power of Go Standard Library.


• Practical recipes that will help you work with the standard library algorithms to boost your productivity as a Go developer.


• Compose your own algorithms without forfeiting the simplicity and elegance of the Standard Library.

Book Description

Google's Golang will be the next talk of

the town, with amazing features and a

powerful library. This book will gear you

up for using golang by taking you through

recipes that will teach you how to leverage

the standard library to implement a

particular solution. This will enable Go

developers to take advantage of using

a rock-solid standard library instead of

third-party frameworks.

The book begins by exploring the

functionalities available for interaction

between the environment and the

operating system. We will explore

common string operations, date/time

manipulations, and numerical problems.

We'll then move on to working with

the database, accessing the filesystem,

and performing I/O operations. From a

networking perspective, we will touch on

client and server-side solutions. The basics

of concurrency are also covered, before

we wrap up with a few tips and tricks.

By the end of the book, you will have a

good overview of the features of the

Golang standard library and what you can

achieve with them. Ultimately, you will be

proficient in implementing solutions with

powerful standard libraries.
