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.

Render/functional components


We're going to take a detour and pivot away from validation and animations to consider the use of functional components and render functions to improve application performance. You may also hear these being referred to as "presentational components" as they're stateless and only receive data as an input prop.

So far, we've only declared the markup for our components with the template tag, but it's also possible to use the render function (as seen in src/main.js):

import Vue from 'vue'
import App from './App.vue'

new Vue({
  el: '#app',
  render: h => h(App)
})

The h comes from hyperscript that allows us to create/describe DOM nodes with our JavaScript. In the render function, we're simply rendering the App component and in the future, we'll be looking at this in more detail. Vue creates a Virtual DOM to make working with the actual DOM much simpler (as well as for improved performance when dealing with a vast amount of elements).
