Book Description

Almost every web application and site out there handles user input in one way or another, from registration forms and log-in handling to registration and landing pages. Building Forms with Vue.js follows a step-by-step approach to help you create an efficient user interface (UI) and seamless user experience (UX) by building quick and easy-to-use forms.

You'll get off to a steady start by setting up the demo project. Next, you'll get to grips with component composition from creating reusable form components through to implementing the custom input components. To further help you develop a convenient user input experience, the book will show you how to enhance custom inputs with v-mask. As you progress, you'll get up to speed with using Vuelidate and Vuex to effectively integrate your forms. You'll learn how to create forms that use global state, reactive instant user input validation and input masking, along with ensuring that they are completely schema-driven and connected to your application's API. Every chapter builds on the concepts learned in the previous chapter, while also allowing you to skip ahead to the topics you're most interested in.

By the end of this book, you will have gained the skills you need to transform even the simplest form into a crafted user and developer experience with Vue.

What you will learn

• Learn all about the basics of creating reusable form components with the Vue framework
  
  


• Understand v-model and how it plays a role in form creation
  
  


• Create forms that are completely powered and generated by a schema, either locally or from an API endpoint
  
  


• Understand how Vuelidate allows for easy declarative validation of all your form's inputs with Vue's reactivity system
  
  


• Connect your application with a Vuex-powered global state management
  
  


• Use the v-mask library to enhance your inputs and improve user experience (UX)

Who this book is for

If you are a developer with basic Vue experience who wants to enhance your forms, then this book is for you. No previous experience with any of the libraries used in the book is required.

Foreword

I first became aware of Marina through her educational work, writing fun and accessible articles about Vue ranging from the very basics to advanced concepts such as object constancy and configuring Vue CLI. I later learned about her work on the Vuelidate team, building some of the most robust form libraries in the Vue ecosystem. Now I get to work with her directly as one of the first people I go to for help breaking down a difficult new concept for the Vue ecosystem.

I'm the one who recommended she write this book, as it's long overdue and she's the perfect person for the job. Building and maintaining complex forms in Vue is among the topics I get asked about the most, but comprehensive resources are still rare. Marina uses her expertise in this domain to provide the most approachable and complete introduction to the essential tools and strategies I've yet seen. It's a must-read for anyone who uses Vue, builds forms, and still has questions.

Preface

Vue.js is one of the world's leading and fastest growing frameworks for frontend development. Its gentle learning curve and vibrant and helpful community have made it an easy choice for many new developers looking to harness the power of frontend frameworks. Additionally, its flexibility and power have made it an easy choice for advanced developers and companies to use it as their main tool for powerful, dynamic, and lean applications and websites.

In Building Forms with Vue.js, we will explore a specific part of frontend development—forms. We will journey together, from creating the most basic forms all the way through to understanding how a fully dynamic, schema-driven form works.

Who this book is for

Building Forms with Vue.js is aimed at frontend developers who have a basic understanding of the Vue.js framework and who want to understand how to better create powerful and reusable forms.

What this book covers

Chapter 1, Setting up the Demo Project, will guide you through setting up the base of the project that we will be building on throughout the book. It is recommended that you work through the book in the order of the chapters, as they build on the concepts learned in the previous ones. However, the completed code for each chapter will be provided at the beginning of each in case you want to skip forward.

Chapter 2, A Form in its Simplest Form, shows the basics of building a basic web form, and the process of connecting the inputs to your app's state. You will also learn about the basics of submitting the form, and using the Axios library to make asynchronous calls to the backend.

Chapter 3, Creating Reusable Form Components, will teach you how to break down a form into components that can be reused throughout your application. You will understand how the v-model directive works and how the main application and form can leverage these components.

Chapter 4, Input Masks with v-mask, touches upon using the v-mask library to allow for input masking to improve user experience. You will learn how to implement third-party plugins and how to incorporate them into your custom components.

Chapter 5, Input Validation with Vuelidate, walks you through the process of adding Vuelidate—a powerful form validation library—to your project, creating validation rules and applying them to your form, as well as how to incorporate it into your custom components.

Chapter 6, Moving to a Global State with Vuex, takes things a step further by transferring the current application's local state to a global state by leveraging the power of Vuex—the official global state management library and pattern. We will incorporate Vuelidate and our custom components into the mix.

Chapter 7, Creating Schema-Driven Forms, brings all the previous concepts together and walks you through the process of understanding and creating a renderer component that allows your application to be fully schema-driven. It will react to API changes provided by a mock API, as well as provide an explanation of how to generate a fully constructed form complete with data submission to the mock backend.
