Veu.js, the brand new JS framework in the market. The crazy for this JS is because of the smarter ways it adopts in performing the task.
Vue.js is important not only because its ability to create server side rendered one or single page apps with the backend development of Node.js.
Looking at the working of this Vue.js, it resembles to that of ReactJS. Yes, it is true that the working of these two tools is more or less the same.
The similarities between these two tools are similar in terms of making available responsive and composable view components, employing virtual DOM, will focus on the main library with concern, the companion libraries and routing will take care the global-state supervision.
Vue.js- the integration of the best of the best from ReactJS and AngularJS
The Vue.js has got the best of the best, inspired from Angular JS and ReactJS. The various best element with it got from angular JS are two way binding when needed, similar templates with good syntax.
And the various best element it has got from React JS are props, performance, understanding of importance of proper state management of apps, component-based approach, one way data flow of components hierarchy, virtual rendering ability.
Angular JS forms the Basis
Evan You, the creator of Vue.js has worked on lot many angular JS projects in Google. During his operations on Angular JS, he got interest in developing a new JS which includes the best element of Angular JS without any extras.
Thus, Angular JS forms the basis for the development of Vue.js and hence the Vue.js’s syntax is similar to that of the angular JS. Not only the Vue.JS but also, this angular JS is the basis for many other JS framework in the early stages of development.
In order to overcome the drawbacks of angular JS, Evan You has developed a brand new JS, called Vue.js.
Unique Features of Vue.JS
1- Flexibility and Modularity
Vue.js is a modular replacement to the Angular JS and is flexible, unlike the angular JS which is very much opiniated with regard to the application structuring.
The best part of Vue.js is that it offers a web-pack template without restricting the access to advanced feature sets like CSS extraction, module reloading, linting, etc.
3- Role of Directives and Components
Directives and components has well defined roles in Vue.js. Components in Vue.js are self-sufficient elements with their own data logic and views, and Directives will encapsulate the DOM manipulations.
Whereas, in Angular JS, components and directives do not exist separately, Components exist as a subset of directives.
4- Simplicity of Vue.js
With respect to design and API, Vue.js is simpler. The simplicity of Vue.js makes it possible for the app developers to develop app in a day, unlike the Angular JS.
5- Runtime Performance
Vue.js with its definite edges will abstain the e dirty checking, and clear dependency-tracking observation system with queueing which will ensure the changes trigger individually.
On the other hand, Angular JS is slow with many watchers, which with a single change in the scope will force all the watchers to evaluate again.
Comparing React JS and Vue.Js
Templates vs JSX
All the components in reactJS uses JSX within the render functions in order to express their UI, a XML similar to syntax which encompasses itself to JS, on the other hand, in Vue.js uses templates which is a best alternative for JSX.
Thus, all the valid HTML is also a valid Vue.js template. Though Vue.js is developed using template approach, it will also support JSX and render functions
The component dependency during rendering is tracked in Vue.js, with helps in knowing about the status of various components during rendering. This is required to avoid the nested component forewarnings.
CSS which has component scope
The styling methods used in Vue.js are very friendly and happens in a single file components, this makes it have access to CSS in the file as the remaining part of the component code.
Whereas, in Reactjs, this is achieved using CSS-in-JS solutions, resulting in a new component oriented styling which is not similar to CSS authoring process.
Versatility of Vue.js
Vue.js, which is an open source progressive JS framework is used for developing the interactive web interfaces. Vue.JS with the use of view layer, will offer many functionalities and serves as a best framework for building powerful single-page-web apps.
The versatile features of Vue.js are as follows
This feature of Vue.js helps in changing the styles, assigning or manipulating the values to HTML attributes, and with the help of binding directives called V-bind, Vue.js will assign classes.
The templates used in Vue.js are HTML bases and this can bind DOM with the Vue.js instance data. The templates are compiled into virtual DOM, in order to render function. The usage of templates of render function is replaceable.
Watchers are required to keep a check on data changes. If the data changes are monitored properly, then the coding process becomes fast and simple.
Virtual DOM is a replica of principal DOM element, which works for absorbing each changes which are intended for the DOM and exist as JS data structures. The various changes made in this JS data structures are compared with that of the original data structure.
In the real DOM will reflect only the final changes which are made visible to the users. The advantages of using this Virtual DOM in Vue.js are it is less expensive, ingenious, and faster.
CSS Transitions and Animation
With the help of Vue.js, the developers can easily add third party animation libraries for making the user experience more interactive.
Also, there are various methods to apply transitions to the HTML elements as Vue.js contains an in built transition component which will wrap the elements of returning transition effect.
With the help of this feature, it is possible to listen to the various changes which are made to the UI element and execute the required calculations. No need of any additional coding required for this.
There are three ways for making the component use Vue.js’s reactive nature, which are explained as follows
Methods are required for altering the component’s state or when any event which is occurring irrelevant to the instance data. Methods cannot track the dependencies, but can take arguments. Every time, when a component is reloaded, method will get triggered and it will have side effects within components.
If a property is changed, then it may show effect on another property, in such case use computed property. These computed properties are dependent on other data properties and these are cached based on the dependencies which will rerun only when if any dependency changes.
For performing logics, when any specific property changes, watchers are required. They act only on one property. This servers very useful, in case of asynchronous or expensive operations.
