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.

Lifecycle hooks


We have access to a variety of lifecycle hooks that fire at particular points during the creation of our Vue instance. These hooks range from prior to creation with beforeCreate, to after the instance is mounted, destroyed, and many more in between.

As the following figure shows, the creation of a new Vue instance fires off functions at varying stages of the instance lifecycle.

We'll be looking at how we can activate these hooks within this section:

Vue.js instance lifecycle hooks

Taking advantage of the lifecycle hooks (https://vuejs.org/v2/guide/instance.html) can be done in a similar way to any other property on our Vue instance. Let's take a look at how we can interact with each one of the hooks, starting from the top; I'll be creating another project based on the standard webpack-simple template:

// App.vue
<template>
</template>

<script>
export default {
 data () {
   return {
    msg: 'Welcome to Your Vue.js App'
   }
 },
 beforeCreate() {
  console...
