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 4. Vue.js Directives

When writing Vue applications, we have access to a variety of powerful directives that allow us to shape the way our content appears on the screen. This allows us to craft highly interactive user experiences with additions to our HTML templates. This chapter will be looking at each one of these directives in detail, as well as any shortcuts and patterns that allow us to improve our workflow.

By the end of this chapter you will have:

  • Used attribute binding to conditionally change element behavior
  • Investigated two-way binding with v-model
  • Conditionally displayed information with v-if, v-else, and v-if-else
  • Iterated over items in a collection with v-for
  • Listened to events (such as keyboard/input) with v-on
  • Used event modifiers to change the binding of a directive
  • Used filters to change the view data of a binding
  • Looked at how we can use shorthand syntax to save time and be more declarative
