What Is Vue JS: Basic Concepts, Benefits & API Styles

Different javascript frameworks are used to build websites and selecting which framework to develop your website is a choice that depends on several parameters.  For web programmers, it is important to choose the proper JavaScript framework that not only serves their current website development needs but also provides code of high quality and good performance. Vue.js as a frontend framework that you can use to build the best interfaces because its key concept of Vue.js is easy to learn and implement. Moreover, it is used to support Vue.js in decorating web pages generally. In this blog, you will get to know what is Vue.js and the benefits of Vue.js. 

Top web development frameworks

Out of the top web development frameworks, JavaScript has many libraries or frameworks to facilitate the development of web applications by providing pre-written code to add desired rich interactivity.  Such functionality might include client-side routing, the manipulation of data and handling complex states. Visual design, charting and dashboards, animation, drag and drop and event handling are some of the purposes served by frameworks. The key concept of Vue.js included in the Vue.js is a prime example of the framework of JavaScript. 

What is Vue.js?

What is Vue.js framework? Javascript is widely used for both web-based and standalone applications. All of its frameworks are dynamic in nature and vue.js is one of them. It is a framework to develop stunning user interfaces. Even, meticulous and intricate projects can be developed using the framework. The framework is open-source and rapidly growing and developed by then Google employee, Evan You. One of the biggest attractiveness of the framework is its ability to create user interfaces using HTML, CSS and Javascript. Most prominent companies such as Baidu, Alibaba, 9GAG and GitLab appreciate the framework’s cohesiveness and effectiveness. The framework is competing with react.js in several aspects and will soon outshine it. 

Why Use Vue JS?

Among many frameworks of Javascript, the benefits of vue js are numerous. One is its user-friendly environment. It is easy to start a web development with Vue.js. 

1. A great Command Line Installer (CLI) tool packed with Vue

 2. Speed

 3. Official packages like Vuex and Vue Router

 4. Single file components

 5. Lightweight

 6. Great and easy-to-understand documentation

 7. Can be progressively adopted into the webpage

8. It is a highly adaptable framework for integration

9. Implementation easiness

How does it work

Vue Js comes with a reactivity system. As a first step, you create a Vue instance. During the instantiation of Vue, you create some properties. When you define a data property (specific property of the Vue object) Vue creates getters and setters for it. These are JavaScript functions bound to a JavaScript object, whose purpose is to dynamically return a computed value and to find changes dynamically in a specified property. 

Benefits of Vue, js

• Easy to learn – It has a simple learning curve.
• Lightweight – Smaller than other libraries of Javascript
• Performance – High speed and faster performance are guaranteed
• Flexible – Developers can choose how to create templates, whether it is an HTML or Javascript files
• Thriving community – It has a growing community

Key concept of Vue.js

• Virtual DOM – VDOM is the speciality of the framework’s rendering system. When modification is required modifications are used by forming a new javascript object.
• Data Binding – Changing the attribute value dynamically easy peasy with V- bind, the binding directive.
• Components – Components are not at all dependent elements in Vuejs that allow the division of user interfaces into reusable pieces so that developers can work on them as silos. When you create a new element with a component, it can be used multiple times in HTML.
• Event Handling – The Event handler value can be either method handlers or inline handlers and Vuejs use the V-on directive property in DOM. 
• Transition – The transition component is a built-in component of Vuejs that lets automatic addition or removal of CSS classes to trigger animation as per the changes in DOM. Vue.js also has a <TransitionGroup> component that can apply animations when an element or component is inserted into, removed from, or moved within a v-for list. You can even add third-party elements. 
• Templates – HTML templates can be used by web developers to declaratively bind DOM. 
• Directives – All in all front-end tasks can be carried out using directives. There are many directives in Vuejs. 
• Routing – If you want to navigate elements in single-page applications Vue -the router is the only option you have. 

What is composition API in Vue and options API in Vue?

Options API and composition API are two types of APIs.  The first is the classic most traditional style of API which uses component logic in methods as well as data. It is ideal for simple web applications or in the case you want to make a straightforward application.

On the other hand, imported functions are used in composition API compared to declarative. It comprises dependency injection, lifecycle hooks and reactivity API. 

The decision of which API to follow in your next project is solely the developer’s choice because both are good enough to create simple to intricate website applications with stunning user interfaces. 

Is Vue better than angular or react?

React, Angular and Vue.js are popular as well as useful libraries or frameworks of Javascript. Is vuejs better than React or  Is Vue better than Angular depends on several variables such as the following factors:

• Speed – Vuej has more speed compared to both other frameworks
• Performance – Lighter DOM than react to ensure high performance
• Debugging – It has intuitive debugging
• Ease of use – A beginner can use the framework to develop an application
• Trust- Angular and React framework have more authenticity than Vue.js

 Working in the Vue JS framework is straightforward to understand even for non-experienced developers. The knowledge base needed to create a basic application is not that high hence you can learn the basics really fast. It will continue to evolve and be loved by developers all around the world. Newer versions will have more advanced features. It is easy to learn and easily integrable than other frameworks helping developers to achieve desired output interestingly.
