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.

Rendering dynamic content

Now that we understand how to serve static content using the net/http package, let’s take a look at adding some dynamic content using Gorilla Mux found here: https://github.com/PacktPublishing/Full-Stack-Web-Development-with-Go/tree/main/Chapter04/dynamic. Execute the server using the following command:

go run main.go

Launch your browser and enter http://localhost:3333 as the address; you will see a login screen similar to the static content. Perform the following steps on the login screen:

  1. Enter any combination of username and password on the login screen.
  2. Click the Login button.

You will get a Login unsuccessful message, as shown in Figure 4.4.

We have introduced dynamic content for our login operation, which means the application will serve pages based on certain conditions, in this case, the successful validation of the username/password combination...
