By: Marina Mosti

Overview of this book

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.

Creating validation rules

When we added Vuelidate to our project through Vue.use, the library added a new reserved property that we can use on our components: validations.

This property is added onto the configuration object for the component, alongside data(), computed, and so on. It will also be an object that holds a property of its own for each input that we want to validate.

Let's create this property and set up a new input, without a custom component wrapper to test. Once we understand the basics, we can work on translating all of this into our BaseInput and BaseSelect components.

Follow these steps in order to create validation rules:

  1. Create a new <input> form below the telephone object of BaseInput in App.vue:
<input type="text" v-model="form.website" />

  1. Remember to add this new property, website, to the form object of data...
