What is the framework vue

Vue is a progressive JavaScript framework for building user interfaces. It is one of the more popular front-end frameworks and one of the commonly used tools among developers. Vue has other features, such as single-file components, the richness of its ecosystem and plugins, etc., that are one of the reasons why it becomes very attractive.

Vue’s component-based development ideas have left a deep impression on many developers. But if you don’t know what Vue is yet, or haven’t used it, then read on to learn more about Vue.

The main features of Vue

Vue.js is an easy-to-use JavaScript framework that supports a variety of features, including:

1. Componentization: Vue's The component style allows you to create and use encapsulated, self-contained, and reusable UI components. Each component part can be developed like an independent complete application.
2. Responsive data binding: Vue supports reactive data binding, which means that changes in data state automatically update and re-render the bound DOM elements.
3. Command system: Vue extends the functions of HTML templates through commands, allowing you to bind the behavior of DOM elements, such as event listening, conditional rendering, attribute binding, etc.
4. Ecosystem: Vue has a large-scale ecosystem that contains all the tools and plug-ins you need, such as routing, state management, build tools, UI component libraries, etc.

The core of Vue

The core of Vue.js is its virtual DOM (virtual DOM) implementation. It can be said to be one of the core technologies of Vue. It is a lightweight rendering engine implemented in JavaScript that can create and update all aspects of the virtual DOM element tree.

Virtual DOM is a proxy JavaScript object tree that is built on an abstraction level over browser DOM elements. When operating on the virtual DOM, Vue will automatically update the actual DOM elements to ensure that operations in the virtual DOM are also displayed correctly on the screen.

Vue’s virtual DOM and responsive data binding make Vue’s performance very good. Complex interactive web applications can be easily created using Vue.

Single File Components (SFCs) of Vue.js

In addition to virtual DOM, another feature of Vue.js worth mentioning is single file components, or SFCs for short.

SFCs is a way to develop Vue applications that can split the application into multiple independent components and write the HTML template, JavaScript and CSS of each component in the same file, thus making The entire component is more readable, maintainable and reusable.

In the Vue tool chain, a single-file component will be parsed into a JavaScript function called the render function. This function is responsible for compiling the component's HTML template into a virtual DOM node, and binding the template and component's data state together.

Due to the excellent features of SFCs, Vue has become so popular in component development and has become one of the preferred frameworks for many developers.

Summary

In this article, we have briefly taken a look at some important features and advantages of the Vue framework, including componentization, reactive data binding, directive system, virtual DOM and single file components.

Vue is playing an increasingly important role in front-end frameworks. It is a powerful, low-threshold development tool that makes front-end development easier and more interesting. Both startups and large companies are expected to adopt this very popular framework to develop various types of applications, from simple static websites to complex web applications.
