Vue.js

Vue.js is an open-source progressive JavaScript framework used to develop interactive web user interfaces and single-page applications. Vue.js is mainly focused on the view part of the application that is also called front end development. Vue.js is going popular day by day because it is very easy to integrate with other projects and libraries. It is very simple to install and use. Even beginners can understand it easily and start building their own user interfaces. In this tutorial, you will learn what is Vue.js, how to install Vue.js, Vue.js Instances, Components, Properties, Bindings, Events, Rendering, Directives, Routing, Mixins, Render functions etc.

Vue.js is an open-source progressive JavaScript framework used to develop interactive web user interfaces and single-page applications (SPAs). Vue.js is commonly referred to as Vue and pronounced as "view.js" or "view."

A single page application or SPA is a web application or a website that provides users a very fluid, reactive, and fast experience similar to a desktop application. A single page application contains a menu, buttons, and blocks on a single page. When a user clicks on any of them, it dynamically rewrites the current page rather than loading entire new pages from a server. That's the reason behind its reactive fast speed. Vue is basically developed for frontend development, so it has to deal with a lot of HTML, JavaScript, and CSS files. Vue.js facilitates users to extend HTML with HTML attributes called directives. Vue.js provides built-in directives and a lot of user-defined directives to enhance functionality to HTML applications.

Features of Vue.js

Components

Vue.js Components are one of the important features of this framework. They are used to extend basic HTML elements to encapsulate reusable code. You can create reusable custom elements in Vue.js applications that can be later reused in HTML.

Templates

Vue.js provides HTML-based templates that can be used to bind the rendered DOM with the Vue instance data. All Vue templates are valid HTML that can be parsed by specification-compliant browsers and HTML parsers. Vue.js compiles the templates into Virtual DOM render functions. Vue renders components in virtual DOM memory before updating the browser. Vue can also calculate the minimum number of components to re-render and apply the minimum amount of DOM manipulations when you change the application's state.

Reactivity

Vue provides a reactivity system that uses plain JavaScript objects and optimizes re-rendering. In this process, each component keeps track of its reactive dependencies, so the system knows precisely when, and which components to re-render.

Routing

Navigation between pages is performed with the help of vue-router. You can use the officially-supported vue-router library for your Single Page Application or if you only need a simple routing and do not want to use the full-featured router library.
