Vuex Quick Start Guide

By: Andrea Koutifaris

Overview of this book

State management preserves the state of controls in a user interface. Vuex is a state management tool for Vue.js that makes the architecture easier to understand, maintain and evolve. This book is the easiest way to get started with Vuex to improve your Vue.js application architecture and overall user experience. Our book begins by explaining the problem that Vuex solves, and how it helps your applications. You will learn about the Vuex core concepts, including the Vuex store, changing application state, carrying out asynchronous operations and persisting state changes, all with an eye to scalability. You will learn how to test Vuex elements and Vue components with the Karma and Jasmine testing frameworks. You will see this in the context of a testing first approach, following the fundamentals of Test Driven Development. TDD will help you to identify which components need testing and how to test them. You will build a full Vuex application by creating the application components and services, and persist the state. Vuex comes with a plugin system that allows programmers to extend Vuex features. You will learn about some of the most powerful plugins, and make use of the built-in logger plugin. You write a custom Google Analytics plugin to send actions to its analytics API, and an Undo/Redo plugin.

Designing the EveryNote web app

One way to start designing an application is by creating mock-ups of the user interfaces. This way, you can present your mock-ups to your stakeholders, discuss them, update your mock-ups accordingly, and resubmit them to stakeholders. This can be done before you start developing.

The EveryNote app will look like the following mock-up:

Figure 3.2: EveryNote mock-up interface

The application will have the following features:

  • Create new notes
  • Show all notes
  • Update an existing note
  • Delete a note
  • Save notes to LocalStorage

After basic features are implemented, we will also add two more features:

  • Search among notes
  • Pin a note

In a real-world application, you may need user stories to better define what the behaviors expected are and, thus, what programmers should code. These stories can be tested, and this type of test is called an acceptance test...
