Vue.js 2 Design Patterns and Best Practices

By: Paul Halliday

Overview of this book

Vue.js 2 Design Patterns and Best Practices starts by comparing Vue.js with other frameworks and setting up the development environment for your application, and gradually moves on to writing and styling clean, maintainable, and reusable Vue.js components that can be used across your application. Further on, you'll look at common UI patterns, Vue form submission, and various modifiers such as lazy binding, number typecasting, and string trimming to create better UIs. You will also explore best practices for integrating HTTP into Vue.js applications to create an application with dynamic data. Routing is a vitally important part of any SPA, so you will focus on the vue-router and explore routing a user between multiple pages. Next, you'll also explore state management with Vuex, write testable code for your application, and create performant, server-side rendered applications with Nuxt. Toward the end, we'll look at common antipatterns to avoid, saving you from a lot of trial and error and development headaches. By the end of this book, you'll be on your way to becoming an expert Vue developer who can leverage design patterns to efficiently architect the design of your application and write clean and maintainable code.

Form validation


Throughout the book, we've looked at various different ways that we can capture user input with the likes of v-model. We'll be using a third-party library named Vuelidate to perform model validation depending on a particular ruleset. Let's create a playground project by running the following in your Terminal:

# Create a new Vue project
$ vue init webpack-simple vue-validation

# Navigate to directory
$ cd vue-validation

# Install dependencies
$ npm install

# Install Vuelidate
$ npm install vuelidate

# Run application
$ npm run dev

What is Vuelidate?

Vuelidate is an open source, lightweight library that helps us perform model validation with a variety of validation contexts. Validation can be functionally composed and it also works well with other libraries such as Moment, Vuex, and more. As we've installed it in our project with npm install vuelidate, we now need to register it as a plugin within main.js:

import Vue from 'vue';
import Vuelidate from 'vuelidate';
import App...
