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.

Integration of the feature flag

After we have installed the feature flag server, we want to start using it in our application. In this section, we will look at integrating the feature flag to enable/disable certain user interface elements in the frontend and to call only the backend services from our server that are enabled.

Web application

The sample app we are going to use can be found inside the chapter11/frontend-enable-disable folder; the sample app demonstrates how to use the feature flag to enable/disable the user interface button. Open the terminal and change into the chapter11/frontend-enable-disable directory to run the web app as follows:

npm install
npm run dev

The commands will install all the necessary packages and then run the web app. Once the command completes, open your browser and type http://localhost:3000 in the address bar. You will see the web app shown in Figure 11.5.
