Learning Vue.js 2

By: Olga Filipova

Overview of this book

Vue.js is one of the latest new frameworks to have piqued the interest of web developers due to its reactivity, reusable components, and ease of use. This book shows developers how to leverage its features to build high-performing, reactive web interfaces with Vue.js. From the initial structuring to full deployment, this book provides step-by-step guidance to developing an interactive web interface from scratch with Vue.js. You will start by building a simple application in Vue.js which will let you observe its features in action. Delving into more complex concepts, you will learn about reactive data binding, reusable components, plugins, filters, and state management with Vuex. This book will also teach you how to bring reactivity to an existing static application using Vue.js. By the time you finish this book you will have built, tested, and deployed a complete reactive application in Vue.js from scratch.

I just did it and it made me feel really nice and cute:

I'm not your clothes... please have some rest

Let's start with mutations. Open the code in the chapter7/pomodoro folder. Open the mutations.js file and check what is happening out there. There are four mutations happening: START, STOP, PAUSE, and TOGGLE_SOUND. Guess which one we will start with. Yes, you are right, we will start with the start method. Create a vuex subfolder inside the test/unit/specs folder and add the mutations.spec.js file. Let's bootstrap it to be ready for tests:

// mutations.spec.js 
import Vue from 'vue' 
import mutations from 'src/vuex/mutations' 
import * as types from 'src/vuex/mutation_types'
