Vue.js Quick Start Guide

By: Ajdin Imsirovic

Overview of this book

Vue.js is the latest trending frontend framework. Simplicity, reactivity, and ?exibility are some of the key benefits that Vue offers to developers. This book will help you learn everything you need to know to build stunning reactive web apps with Vue.js 2 quickly and easily. This book will take you through the Vue 2 framework. You will start by learning the different Vue installation options: CDN, NPM, and Vue CLI. Then we will look at the core concepts of Vue: templates and components – ways to modularize Vue code. You will learn how to utilize directives, which are Vue-specific HTML attributes with additional features. Also, you will see how Vue uses a streamlined approach to development, with reusable methods, computed properties, and watchers, and how it controls state with the help of its data option. You will learn about the concepts of reactive programming in Vue, and how to understand communication between parent and child components. We will take a look at props and slots, working with CSS, filters, and mixins. We will also look at ways to add transitions and animations to Vue apps. Then you will extend Vue by building custom directives and your own plugins. Finally, you will learn about Vuex – a Vue plugin that allows us to centralize state, and also introduce Nuxt, which is a framework that builds on top of Vue and solves some issues of single-page applications. After learning about these components, you will be ready to build your own reactive web apps with Vue.js 2.

State management, data stores, and one-way data flows

A common solution to the problem of managing complex state is the idea of a store: a single source of truth that keeps all of the data of our app's state. Once we have that central location—the store—we can reason about state a lot easier, because now it is only a matter of sending the state data to those components that need to have it at any time in the app's life cycle.

To make the state updates simpler, we need to limit the ways in which these updates can be made. This is where one-way data flows come in. With one-way data flows, we specify rules on exactly how data can flow inside our app, which means that there are now only so many expected ways in which data (state) can flow through our apps, making it easier to reason about state and debug state when needed. This approach is also a great time saver, since now we as developers know what to expect; that is, to look for spots where we know state is mutable.
