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.

You can use feature flags by deploying them in your infrastructure or by using software-as-a-service solutions such as LaunchDarkly, Flagsmith, and many other available solutions. Each of the solutions provides its own API, which needs to be integrated into your application. This means that your application is tied to the solution that you choose. There is no one-size-fits-all solution; it all depends on what kind of features you need for your application.

Let’s take a look at different kinds of configuration for using feature flags. Figure 11.1 shows the simplest way to use feature flags.

The web client will enable or disable the user interface depending on the feature flag. For example, in an application, a particular menu selection can be enabled when the feature flag related to the menu is turned on.
