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.

Tracing applications

In the previous chapter, we learned about logging and how logging can give us visibility into what’s going on inside our application. The line between logging and tracing is blurry; what we need to understand is that logging just provides information on what a process is currently doing, while tracing gives us cross-cutting visibility across different components, allowing us to get a better understanding of the data flow and time taken for a process to complete.

For example, with tracing, we can answer questions such as the following:

  • How long does the add-to-cart process take?
  • How long does it take to download a payment file?

We will go through the different APIs that are outlined in the specification and implement those APIs using the implementation provided by the OpenTelemetry library.

The following figure shows the links between different entities.
