Full-Stack Web Development with Go

By: Nanik Tolaram, Nick Glynn

Overview of this book

Go is a modern programming language with capabilities to enable high-performance app development. With its growing web framework ecosystem, Go is a preferred choice for building complete web apps. This practical guide will enable you to take your Go skills to the next level building full stack apps. This book walks you through creating and developing a complete modern web service from auth, middleware, server-side rendering, databases, and modern frontend frameworks and Go-powered APIs. You’ll start by structuring the app and important aspects such as networking, before integrating all the different parts together to build a complete web product. Next, you’ll learn how to build and ship a complete product by starting with the fundamental building blocks of creating a Go backend. You’ll apply best practices for cookies, APIs, and security, and level up your skills with the fastest growing frontend framework, Vue. Once your full stack application is ready, you’ll understand how to push the app to production and be prepared to serve customers and share it with the world. By the end of this book, you’ll have learned how to build and ship secure, scalable, and complete products and how to combine Golang with existing products using best practices.

Using golog

Now that we understand what is available in the standard library, we want to explore the option of using a library that can provide us with more flexibility. We will look at the golog open source project (https://github.com/kataras/golog). The golog library is a dependency-free logging library that provides functionality such as leveled logging (INFO, ERROR, etc.), JSON-based output, and configurable color output.

One of the most used features of logging is log levels, also known as leveled logging. Log levels are used to categorize output information from an application into different severity levels. The following table shows the different severity levels:

...

INFO

Just for information purposes

WARN

Something is not running correctly, so keep an eye out for it in case there are more severe errors

ERROR
