Vue.js vs React vs Angular vs Polymer: Which is Most Popular Framework?
If you’re a developer initiating out on which JavaScript framework to use, this entire blog will help you make a decision.
There are lots of JavaScript libraries out there. Four of the most popular today are React, Polymer, Angular, and Vue. There are a lot of similarities among them; all are based on components that get input and return a user interface element. The developers might be debating on whether they should be using Angular, vuejs, react or polymer for their projects.
Prerequisites
- Knowledge of HTML & CSS
- Knowledge of basic JavaScript
- The familiarity of ES6 + features & the syntax
- Node.js and npm (or yarn) installed globally
- The familiarity with REST APIs would be more helpful, but we’ll go over it.
Note: The above prerequisites are the basic and major requirements to attain the complete VueJS. Now, it’s the right moment to apprehend something about vuejs only if you are knowledgeable of the above requirements.
Overview of Vue.js
Vue is famed for its efficiency of use and integrity.VueJS is a high-level JavaScript frame-work with open-source code for the development of user interfaces. VueJS is a pretty popular JavaScript framework, one that is encountering huge growth.
VueJS is considerably simple, tiny with (~24 KB) and very performant. If we talk about its history, then vue was created by Evan You after working for Google using AngularJS in a number of projects.
VueJS is so distinctive from all the other JavaScript frontend frameworks and view libraries. Due to the uncomplicated structure of the vue.js, and users can append vueJS to their web projects so effortlessly. Moreover, it also permits users to develop both small as well as large scale templates. This method consumes a lot of moment for the developers. Vue took many good ideas from React, most importantly the Virtual DOM. But Vue implements it with some sort of automatic dependency management, which tracks which components are affected by a change of the state so that only those components are re-rendered when that state property changes.
Features of VueJS
Vue is called as a progressive JavaScript framework with various features for building user interfaces. The following are the major features available with VueJS.
- Improvement & Bug Fixes: In the supplement to providing these new features, vue.js further comes with several improvements and bug fixes.
- Improved Typescript Support & Integration: The most modern version of VueJS render stable support to TypeScript. The improved integration improves the type of declaration process.
- Better Error Handling & Reporting: Whilst using earlier versions of vuejs, programmers have to manipulate with the unexpected errors all through either config.errorHandler option or render an appropriate error component.
- Better Functional Component Support: VueJs renders more considerate assistance to the functional components which are described as a single-file component (SFC). Here, the developers can now appropriate the vue-loader to represent functional components in an individual vue.js file.
- Environment-Agnostic Server-Side Rendering: Unlike the other JS libraries, VueJS appears with built-in streaming server-side rendering. The hallmark makes it quite more accessible for the programmers to execute server-side rendering asynchronously.
VueJS Installing Steps
1. npm install -g @vue/cli
2. vue –version for check version
3. vue create {projectname}
4. need dependency
a. vue-router
b. dart-sass
c. babel
d. pwa
5. sudo npm install –save axios vue-axios { dipendency for ajax request}
6. npm install vue-easysession –save {dipendency for session}
Base Example
Here’s an example of a Vue component:
// Define a new component called button-counter
Components are reusable Vue instances with a name: in this case,
What are VueJS methods?
A vue method is a function associated with the vue instance.
Below is the instance of the methods defined in the methods property.
or in the case of Single File Components:
Overview of Polymer
In the year of 2013, the creative team of Google has pronounced the new JavaScript library named Polymer. an open-source, easy and free JavaScript library aimed for the creation of web applications based on the Web Components technology.
As you may know, Polymer JS was one of the general sources of inspiration for Evan You to create Vue. Currently, the latest version 3.0 of the library is supported by GitHub volunteers apart from the Google guys. We are going to make an objective Polymer JS review by listing the main Polymer JS features. Take a look at the pros and cons of this library, and figure out why to use Polymer JS in your particular project.
Below we are going to provide you some of the foremost features of Polymer, have a look:
Features of Polymer
- Instantiated using a constructor or document.createElement
- Combining with other platforms and frameworks.
- Working with standard JavaScript.
- Popular with internal DOM inside each instance.
A basic Polymer element definition looks like this:
import {PolymerElement, html} from '@polymer/polymer/polymer-element.js';
// Define the element's API using an ES2015 class
class XCustom extends PolymerElement {
// Define optional shadow DOM template
static get template() {
return html`
<style>
/* CSS rules for your element */
</style>
<!-- shadow DOM for your element -->
<div>[[greeting]]</div> <!-- data bindings in shadow DOM -->
`;
}
// Declare properties for the element's public API
static get properties() {
return {
greeting: {
type: String
}
}
}
constructor() {
super();
this.greeting = 'Hello!';
}
// Add methods to the element's public API
greetMe() {
console.log(this.greeting);
}
}
// Register the x-custom element with the browser
customElements.define('x-custom', XCustom);Overview of React
Before taking a deep dive into this foremost framework you should know that React is not a framework. It lets you compose complex UIs from inadequate and isolated pieces of code called “components”.
React (also known as React.js or ReactJS) is a library of javascript that is used for building user interfaces. It is just a library developed by Facebook to solve some problems that we were challenging earlier. It is maintained by Facebook and a community of individual developers and companies. The most significant features of React is a major reality or the fact that you can generate components, which are like custom, reusable HTML elements that swiftly and efficiently develop the user’s interfaces.
Features of React
Currently, ReactJS obtaining quite agile popularity as the most reliable JavaScript framework amid web developers. It is playing a crucial role in the front-end ecosystem. Now, we are going to provide you the essential features of ReactJS in the following section. Let us take a closer look at some important features of React.
- Lightweight DOM For Better Performance
- Easy Learning Curve
- Components Support And Little Dependencies
- The desired interface can be created in a relatively easy manner.
- Error boundaries
Overview of Angular
Angular JS is an open-source web application framework. Angular is a platform and a framework for building the clients’ applications in HTML and TypeScript as it is scribbled in the TypeScript.
Angular JS is a structured, JavaScript framework used for dynamic open-page applications. Being a framework it uses a code template all scribbled in HTML. There is a substantial discrepancy between the static documents and the dynamic applications. While the library contains the number of functions used to perform certain operations, the framework automatically takes the data and calls the exact functions to perform especially when needed.
Features of Angular
The core features of Angular JS are as follows:
- Data-Binding- It is the automatic synchronization of data between model and view components.
- Scope- These are the objects that refer to the model. We can say that they act as a glue between view and controller.
- Controller- These are the functions of JavaScript that bound to the particular scope.
- Dependency Injection- Angular JS holds a built-in dependency injection subsystem that helps the developer to understand, create, test the applications easily.
- Deep-Linking- Here, the deep linking permits to encode the state of application in the URL so that it can be bookmarked. The application can be restored from the URL to the same state.
Expressions in AngularJS
AngularJS expressions can contain literals, operators, or variables, unlike the traditional JavaScript. They could be written inside the HTML tag itself, but care has to be taken to the supplement the ng-app directive, else the expression will be displayed as it is, even without being solved.
AngularJS expressions could be written inside the double curly braces or can be written inside a directive.
Syntax:
Inside curly braces:
Inside directive:
All in All
‘Twas a comprehensive and summarized comparison between the foremost frameworks. Each of the aforementioned libraries holds their own benefits and drawbacks. Based on the design or the project you’re working on, and your specific specifications, one of them is going to be more fitting than the others. It’s perpetually key to do your own research all prior to deciding, particularly if you’re going to be working on a business venture but not on a secluded project.
