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.

Conditionally showing DOM elements


When creating business applications, there'll be many times when you only want to display a particular element if a certain condition is true or false. This could include a user's age, whether the user is logged in, whether it is an administrator or any other piece of business logic you can think of.

For this, we have a variety of conditional directives such as v-show, v-if, v-else, and v-else-if, all of which act in similar yet different ways. Let's take a look at this in more detail by creating a new playground project:

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

# Navigate to directory
$ cd vue-conditionals

# Install dependencies
$ npm install

# Run application
$ npm run dev

v-show

If we want to hide elements from view yet still have them in the DOM (effectively display:none), we can use v-show:

<template>
<div id="app">
 <article v-show="admin">
  <header>Protected Content</header>
 <section class...
