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.

On the topic of performance improvements, let's consider why Vue.js makes extensive use of the Virtual DOM to render our elements on the screen. Before looking at the Virtual DOM, we need to have a foundational understanding of what the DOM actually is.

DOM

The DOM is what is used to describe the structure of an HTML or XML page. It creates a tree-like structure that provides us with the ability to do everything from creating, reading, updating, and deleting nodes to traversing the tree and many more features, all within JavaScript. Let's consider the following HTML page:

<!DOCTYPE html>
<html lang="en">
<head>
 <title>DOM Example</title>
</head>
<body>
 <div>
  <p>I love JavaScript!</p>
  <p>Here's a list of my favourite frameworks:</p>
  <ul>
   <li>Vue.js</li>
   <li>Angular</li>
   <li>React</li>
  </ul>
 </div>
