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.

There are many ways to handle errors when writing web applications. In our sample application, we handle errors to inform users of what’s happening with their request. When reporting errors to users about their request, remember not to expose too much information about what’s happening to the system. The following are some examples of error messages reported to users that contain such information:

  • There is a connection error to the database
  • The username and password are not valid for connecting to the database
  • Username validation failed
  • The password cannot be converted to plain text

The preceding JSON error use cases are normally used in scenarios where more information needs to be provided to the frontend to inform users. Simpler error messages containing error codes can also be used.

Using JSONError

Standardizing error messages is as important as writing proper code to ensure application maintainability. At...
