Book Description



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.

  • Reuse components using slots


  • Use filters, mixins, and global mixins in Vue

    Preface

    Up until a few years ago, direct DOM manipulation was the standard in frontend development, with jQuery leading the way. All that started changing with the popularization of modern JavaScript libraries and frameworks, mainly Angular and React. And then, in February of 2014, Vue came out with its initial release. 

    With large IT companies backing both Angular and React, it was not clear how Vue would carve out its position. Initially developed by a single developer, Evan You, in four short years—and without corporate backing—Vue went from being the fun little project of a single developer to an unlikely rival to the big boys, with over 300 contributors. It's not a one-man show anymore.

    Today, Vue is used by NASA, GitLab, Alibaba, Grammarly, WizzAir, EuroNews, Xiaomi, Adobe, Behance, Nintendo, Chess.com, and many others.

    Conclusion? Vue is here to stay. And while there might be an on-going discussion about whether it's better to learn Elm, or React, or Angular, or Ember, or something entirely different, this discussion is largely irrelevant. Each library and framework has something to offer, and in the end, it's simply a matter of trying it out and seeing whether it works for you.

    We developers need to embrace the necessity to surf the technology wave and accept that learning new frameworks and paradigms is simply a part of our careers. Therefore, the question is not whether we should learn Vue, or any other battle-tested and proven tech out there.

    Vue has already achieved its ranking, and it's playing in the same league with the big boys. The only question is, How do I learn it efficiently? and this book is an attempt to answer that question.

    Who this book is for

    This book is aimed at beginner-to-intermediate frontend web developers with no prior experience with Vue or other VDOM JavaScript libraries. It would be beneficial for readers to have some JavaScript and CSS knowledge. It is aimed at quickly bringing the reader up to speed regarding just how exactly Vue
