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.

Transitions


Transitions work by starting off in one particular state and then transitioning into another state and interpolating the values in-between. A transition can't have multiple steps involved in an animation. Imagine a pair of curtains going from open to closed: the first state would be the open position, while the second state would be the closed position.

Vue has its own tags for dealing with transitions, known as <transition> and <transition-group>. These tags are customizable and can be easily used with JavaScript and CSS. There do not necessarily need to be transition tags to make transitions work, as you simply bind the state variable to a visible property, but the tags typically offer more control and potentially better results.

Let's take the toggle example that we had before and create a version that uses transition:

<template>
 <div id="app">
  <transition name="fadeIn"
  enter-active-class="animated fadeIn"
  leave-active-class="animated fadeOut...
