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.

We'll be using the counter application as an example, to ensure that you have this project running, and right click on Inspect Element from within Chrome (or your browser's equivalent). If we head over to the Vue tab and select Vuex, we can see that the counter has been loaded with the initial application state:

From the preceding screenshot, you can see the count state member as well as the value of any getters. Let's click on the increment button a few times and see what happens:

Awesome! We can see the INCREMENT action as well as a subsequent change to the state andgetters, and more information about the mutation itself. Let's see how we can time travel throughout our state:
