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.

Validating data entry with Vuelidate

If your app does anything interactive, it’s likely that it will handle user-entered data, which means you must check whether what the users are providing is valid input.

Input validation libraries can be used to ensure only valid data is entered by the user and provide feedback as soon as data is received. This means we’re validating as soon our user hits that input field!

We’re going to explore HTML form validation in the frontend and the difference between input and value validation. It’s also important to note that no matter the validation in the frontend, it’s no substitute for validation in the backend and of the API endpoints. Our goal in the frontend is to prevent the user from making errors; however, you’ll never stop bad guys from submitting bad data to your app.

We can look at frontend validation through two lenses, as there’s a myriad of solutions out there, but we’ll contrast...
