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.

Chapter 3. Writing Clean and Lean Code with Vue

In this section, we'll be investigating how a Vue.js instance works at a lower level by looking at how this is handled by Vue. We'll also be looking at the various properties on our instance such as data, computed, watch, as well as best practices when using each one. Furthermore, we'll be looking at the various lifecycle hooks available within our Vue instance, allowing us to call particular functions at various stages of our application. Finally, we'll be investigating the Document Object Model (DOM) and why Vue implements a Virtual DOM for enhanced performance.

By the end of this chapter you will:

  • Have a greater understanding of how this keyword works within JavaScript
  • Understand how Vue proxies this keyword within Vue instances
  • Use data properties to create reactive bindings
  • Use computed properties to create declarative functions based on our data model
  • Use watched properties to access asynchronous data and build upon the foundations of computed...
