Why is Vue JS the most Preferred Choice for Responsive Web Application Development?

For more than two decades, JavaScript has facilitated businesses to develop responsive web applications for their customers. Used both client and server-side, JavaScript enables you to bring dynamics to pages through expanded functionality and real-time modifications.

Did you know!

According to a web development survey 2020, JavaScript is the most used language for the 8th year, with 67.7% of people choosing it. With this came up several javascript frameworks for frontend, backend development, or even testing.

And one such framework is Vue.Js. It is used to build simple projects and can also be advanced to create sophisticated apps using state-of-the-art tools. Beyond that, some other solid reasons give Vuejs a thumbs up for responsive web application development.

Want to know them? Then follow this blog until the end. Through this article, I will describe all the reasons and benefits of Vue js development. So, stay tuned.

Vue.Js - A Brief Introduction

Released in the year 2014 for public use, Vue.Js is an open-source JavaScript framework used to create UIs and single-page applications. It has over 77.4 million likes on Github for creating intuitive web interfaces.

The recent version is Vue.js 2.6, and is the second most preferred framework according to Stack Overflow Developer Survey 2019.

Every Vue.js development company is widely using the framework across the world for responsive web application development. It is centered around the view layer, provides a lot of functionality for the view layer, and builds single-page web applications.

Some most astonishing stats about Vue.Js:

• Vue was ranked #2 in the Front End JavaScript Framework rankings in the State of JS 2019 survey by developers.

• Approximately 427k to 693k sites are built with Vue js, according to Wappalyzer and BuiltWith statistics of June 2020.

• According to the State of JS 2019 survey, 40.5% of JavaScript developers are currently using Vue, while 34.5% have shown keen interest in using it in the future.

• In Stack Overflow's Developer Survey 2020, Vue was ranked the 3rd most popular front-end JavaScript framework.

Why is Vue.Js so popular?

• High-speed run-time performance
• Vue.Js uses a virtual DOM.
• The main focus is on the core library, while the collaborating libraries handle other features such as global state management and routing.
• Vue.JS provides responsive visual components.

Top 7 Reasons to Choose Vue JS for Web Application Development

Vue js development has certain benefits, which will encourage you to use it in your projects. For example, Vue.js is similar to Angular and React in many aspects, and it continues to enjoy increasing popularity compared to other frameworks.

The framework is only 20 kilobytes in size, making it easy for you to download files instantly. Vue.js easily beats other frameworks when it comes to loading times and usage.

Take a look at the compelling advantages of using Vue.Js for web app development.

#1 Simple Integration

Vue.Js is popular because it allows you to integrate Vue.js into other frameworks such as React, enabling you to customize the project as per your needs and requirements.

It helps you build apps with Vue.js from scratch and introduce Vue.js elements into their existing apps. Due to its ease of integration, Vue.js is becoming a popular choice for web development as it can be used with various existing web applications.

You can feel free to include Vue.js CDN and start using it. Most third-party Vue components and libraries are additionally accessible and supported with the Vue.js CDN.

You don't need to set up node and npm to start using Vue.js. This implies that it helps develop new web applications, just like modifying previous applications.

The diversity of components allows you to create different types of web applications and replace existing frameworks. In addition, you can also choose to hire Vue js developers to use the technology to experiment with many other JavaScript applications.

#2 Easy to Understand

One of the main reasons for the growing popularity of Vue.Js is that the framework is straightforward to understand for individuals. This means that you can easily add Vue.Js to your web projects.

Also, Vue.Js has a well-defined architecture for storing your data with life-cycle and custom methods. Vue.Js also provides additional features such as watchers, directives, and computed properties, making it extremely easy to build modern apps and web applications with ease.

Another significant advantage of using the Vue.Js framework is that it makes it easy to build small and large-scale web applications in the shortest amount of time.

#3 Well-defined Ecosystem

The VueJS ecosystem is vibrant and well-defined, allowing Vue.Js development company to switch users to VueJS over other frameworks for web app development.

Without spending hours, you can easily find solutions to your problems. Furthermore, VueJs lets you choose only the building blocks you need.

Although the main focus of Vue is the view layer, with the help of Vue Router, Vue Test Utils, Vuex, and Vue CLI, you can find solutions and recommendations for frequently occurring problems.

The problems fall into these categories, and hence it becomes easy for programmers to get started with coding right away and not waste time figuring out how to use these tools.

The Vue ecosystem is easy to customize and scales between a library and a framework. Compared to other frameworks, its development speed is excellent, and it can also integrate different projects. This is the reason why most website development companies also prefer the Vue.Js ecosystem over others.

#4 Flexibility

Another benefit of going with Vue.Js for web app development needs is flexibility. Vue.Js provides an excellent level of flexibility. And makes it easier for web app development companies to write their templates in HTML, JavaScript, or pure JavaScript using virtual nodes.

Another significant benefit of using Vue.Js is that it makes it easier for developers to work with tools like templating engines, CSS preprocessors, and type checking tools like TypeScript.

#5 Two-Way Communication

Vue.Js is an excellent option for you because it encourages two-way communication. This has become possible with the MVVM architecture to handle HTML blocks. In this way, Vue.Js is very similar to Angular.Js, making it easier to handle HTML blocks as well.

With Vue.Js, two-way data binding is straightforward. This means that any changes made by the developer to the UI are passed to the data, and the changes made to the data are reflected in the UI.

This is also one reason why Vue.Js is also known as reactive because it can react to changes made to the data. This sets it apart from other libraries such as React.Js, which are designed to support only one-way communication.

#6 Detailed Documentation

One essential thing is well-defined documentation that helps you understand the required mechanism and build your application with ease. It shows all the options offered by the framework and related best practice examples.

Vue has excellent docs, and its API references are one of the best in the industry. They are well written, clear, and accessible in dealing with everything you need to know to build a Vue application.

Besides, the documentation at Vue.js is constantly improved and updated. It also includes a simple introductory guide and an excellent overview of the API. Perhaps, this is one of the most detailed documentation available for this type of language.

#7 Large Community Support

Support for the platform is impressive. In 2018, support continued to impress as every question was answered diligently. Over 6,200 problems were solved with an average resolution time of just six hours.

To support the community, there are frequent release cycles of updated information. Furthermore, the community continues to grow and develop with backend support from developers.

Wrapping Up

VueJS is an incredible choice for responsive web app development. Since it is lightweight and user-friendly, it builds a fast and integrated web application. The capabilities and potential of VueJS for web app development are extensive.

While Vuejs is simple to get started with, using it to build scalable web apps requires professionalism. Hence, you can approach a top Vue js development company in India to develop high-performing web apps.

Equipped with all the above features, it doesn't matter whether you want to build a small concept app or a full-fledged web app; Vue.Js is the most performant you can rely on.

A Vue JS Modal Component Mobile Friendly

Vue.js modal

Simple to use, highly customizable, mobile-friendly Vue.js 2.0+ modal with SSR support.


npm install vue-js-modal --save

How to use

Include plugin in your main.js file.

import VModal from 'vue-js-modal'


By default, the plugin will use "modal" name for the component.
If you need to change it, you can do so by providing "componentName" param.


Vue.use(VModal, { componentName: "foo-modal" })
<foo-modal name="bar"></foo-modal>

Create modal:

<modal name="hello-world">
  hello, world!

Call it from anywhere in the app:

methods: {
  show () {
  hide () {

You can easily send data into the modal:

this.$'hello-world', { foo: 'bar' })

And receive it in beforeOpen event handler:

<modal name="hello-world" @before-open="beforeOpen"/>
methods: {
  beforeOpen (event) {

If you use Bower package manager - you will have to initialize library differently:



It is a simplified version of the modal, which has most parameters set by default and is pretty useful for quick prototyping, showing alerts or creating mobile-like modals.

To start using <v-dialog/> you must set dialog: true in plugin configuration:

Vue.use(VModal, { dialog: true })

And include it in your project:


Call it (all params except of “text” are optional):

this.$'dialog', {
  title: 'Alert!',
  text: 'You are too awesome',
  buttons: [
      title: 'Deal with it',
      handler: () => { alert('Woot!') }
      title: '',       // Button title
      default: true,    // Will be triggered by default if 'Enter' pressed.
      handler: () => {} // Button click handler
      title: 'Close'

Vue.js modal

Dynamic Modals

In order to instantiate modals at runtime (for lazy-loading or decluttering templates), it is possible to create modals dynamically.

To start using this feature you must set dynamic: true in plugin configuration:

Vue.use(VModal, { dynamic: true, dynamicDefaults: { clickToClose: false } })

And include the <modals-container/> component it in your project:


Alternatively, the modals container can be automatically appended to the document body once the plugin is loaded using injectModalsContainer: true:

Vue.use(VModal, { dynamic: true, injectModalsContainer: true })

Call it (the first argument is the component definition, the second are component properties, the third modal parameters, and the fourth the modal event listeners):

  template: `
      <h1>This is created inline</h1>
      <p>{{ text }}</p>
  props: ['text']
}, {
  text: 'This text is passed as a property'
}, {
  height: 'auto'
}, {
  'before-close': (event) => { console.log('this will be called before the modal closes'); }

It can also be used with .vue files:

import MyComponent from './MyComponent.vue'

this.$, {
  text: 'This text is passed as a property'
}, {
  draggable: true

Other than defining the name modal parameter, it’s also possible to close dynamic modals emitting a 'close' event:

  template: `
      <p>Close using this button:</p>
      <button @click="$emit('close')">Close</button>

If using the injectModalsContainer flag, the first mounted Vue instance without parents will be treated as the application root. This is only important to keep in mind if more than one root Vue instance is being used, which is unlikely. But if that’s the case, the root to use can be indicated with the root parameter when invoking dynamic modals or modifying this plugin’s rootInstance attribute:

import App from './App.vue'
import VModal from 'vue-js-modal'

const app1 = new Vue({
  el: '#app-1',
  render: h => h(App)

const app2 = new Vue({
  el: '#app-2',
  render: h => h(App)

VModal.rootInstance = app2

It is possible to set default property values for dynamic modals.


import VueJsModal from 'plugin'

Vue.use(VueJsModal, {
  dynamic: true,
  dynamicDefaults: {
    foo: 'foo'
    showDynamicRuntimeModal () {
        template: `
          <div class="example-modal-content">
            <p>{{ text }}</p>
            <p>Default Property: {{ foo }} - value is "foo"</p>
        props: ['text', 'foo']
      }, {
        text: 'This text is passed as a property'

Note: keep in mind that there are some limitations in using dynamic modals. If you need full functionality then use ordinary modal instead.


Include plugin in your nuxt.config.js file:

module.exports = {
  plugins: ['~plugins/vue-js-modal']

And your plugins/vue-js-modal.js will look like:

import Vue from 'vue'
import VModal from 'vue-js-modal/dist/ssr.index'


Extracted CSS

There is also an SSR build with CSS file extracted. Take a look in /dist folder.


Name Required Type Default Description
name true [String, Number] Name of the modal
delay false Number 0 Delay between showing overlay and actual modal box
resizable false Boolean false If true allows resizing the modal window, keeping it in the center of the screen.
adaptive false Boolean false If true, modal box will try to adapt to the window size
draggable false [Boolean, String] false If true, modal box will be draggable.
scrollable false Boolean false If height property is auto and the modal height exceeds window height - you will be able to scroll modal
reset false Boolean false Resets position and size before showing modal
clickToClose false Boolean true If set to false, it will not be possible to close modal by clicking on the background
transition false String Transition name
overlayTransition false String ‘overlay-fade’ Transition name for the background overlay
classes false [String, Array] ‘v–modal’ Classes that will be applied to the actual modal box, if not specified, the default v--modal class will be applied
width false [String, Number] 600 Width in pixels or percents (e.g. 50 or “50px”, “50%”)
height false [String, Number] 300 Height in pixels or percents (e.g. 50 or “50px”, “50%”) or "auto"
minWidth false Number (px) 0 The minimum width to which modal can be resized
minHeight false Number (px) 0 The minimum height to which modal can be resized
maxWidth false Number (px) Infinity The maximum width of the modal (if the value is greater than window width, window width will be used instead
maxHeight false Number (px) Infinity The maximum height of the modal (if the value is greater than window height, window height will be used instead
pivotX false Number (0 - 1.0) 0.5 Horizontal position in %, default is 0.5 (meaning that modal box will be in the middle (50% from left) of the window
pivotY false Number (0 - 1.0) 0.5 Vertical position in %, default is 0.5 (meaning that modal box will be in the middle (50% from top) of the window
root false Vue instance null Root instance to obtain modal container from. This property is only necessary when using dynamic modals with more than one root instance, which is uncommon


Name Description
before-open Emits while modal is still invisible, but was added to the DOM
opened Emits after modal became visible or started transition
before-close Emits before modal is going to be closed. Can be stopped from the event listener calling event.stop() (example: you are creating a text editor, and want to stop closing and ask the user to correct mistakes if the text is not valid)
closed Emits right before modal is destroyed


  <modal name="example"
export default {
  name: 'ExampleModal',
  data () {
    return {
      time: 0,
      duration: 5000
  methods: {
    beforeOpen (event) {
      // Set the opening time of the modal
      this.time =
    beforeClose (event) {
      // If modal was open less then 5000 ms - prevent closing it
      if (this.time + this.duration < {

Example with a dynamic modal:

export default {
  name: 'ExampleModal',
  data () {
    return {
      time: 0,
      duration: 5000
  methods: {
    openModal () {
        template: `<b>{{time}}</b>`,
        props: ['time']
      }, {
        time: this.time
      }, {
        width: 300,
        height: 300
      }, {
        'before-open': this.beforeOpen,
        'before-close': this.beforeClose
    beforeOpen (event) {
      // Set the opening time of the modal
      this.time =
    beforeClose (event) {
      // If modal was open less then 5000 ms - prevent closing it
      if (this.time + this.duration < {

This example initializes time variable every time the modal is being opened. And then forbids closing it for the next 5000 ms


Height: “auto”

From v1.2.6 height can be set to “auto”. If you want to be able to scroll modal in case it’s height exceeds window height - you can set flag scrollable="true".

p.s. scrollable will only work with height="auto".


<modal name="foo" height="auto" :scrollable="true">...</modal>

Auto height:

Scrollable content & auto height:

Close button

If you want to have a Close (x) button in the top-right corner, you can use “top-right” slot for it. There is deliberately no predefined Close button style - you will have to implement/use your own button.


  <modal name="foo">

    <div slot="top-right">
      <button @click="$modal.hide('foo')">

    Hello, ☀️!


Draggable handler

Draggable property can accept not only Boolean but also String parameters. With String value, you can specify a CSS selector to the element which will be a “handler” for dragging.


<modal name="bar" draggable=".window-header">
  <div class="window-header">DRAG ME HERE</div>
     Hello, 🌎!

Overlay background color

If you want to change overlay background color, you can easily do it using CSS.

For all modals:

.v--modal-overlay {
  background: red;

For specific modal:

.v--modal-overlay[data-modal="my_modal_name"] {
  background: transparent;


<modal name="fs" :adaptive="true" width="100%" height="100%">
Dont forget about close button :)


To run an example:

# Clone repo
git clone

# Run unit tests
npm run unit

# Run linter
npm run lint

# Build main library for client & SSR
cd vue-js-modal
npm install
npm run build

# Build and run demo
cd demo/client_side_rendering
npm install
npm run dev

Unit Testing in Vue 2.0 using Jest

Include the plugin to your <Component>.spec.js.

For example: If you’re using the plugin in your Main component, then you should include the plugin to your Main.spec.js file.

import VModal from 'vue-js-modal'

NBB: Ad-hoc CLJS Scripting on Node.js


Not babashka. Node.js babashka!?

Ad-hoc CLJS scripting on Node.js.


Experimental. Please report issues here.

Goals and features

Nbb's main goal is to make it easy to get started with ad hoc CLJS scripting on Node.js.

Additional goals and features are:

  • Fast startup without relying on a custom version of Node.js.
  • Small artifact (current size is around 1.2MB).
  • First class macros.
  • Support building small TUI apps using Reagent.
  • Complement babashka with libraries from the Node.js ecosystem.


Nbb requires Node.js v12 or newer.

How does this tool work?

CLJS code is evaluated through SCI, the same interpreter that powers babashka. Because SCI works with advanced compilation, the bundle size, especially when combined with other dependencies, is smaller than what you get with self-hosted CLJS. That makes startup faster. The trade-off is that execution is less performant and that only a subset of CLJS is available (e.g. no deftype, yet).


Install nbb from NPM:

$ npm install nbb -g

Omit -g for a local install.

Try out an expression:

$ nbb -e '(+ 1 2 3)'

And then install some other NPM libraries to use in the script. E.g.:

$ npm install csv-parse shelljs zx

Create a script which uses the NPM libraries:

(ns script
  (:require ["csv-parse/lib/sync$default" :as csv-parse]
            ["fs" :as fs]
            ["path" :as path]
            ["shelljs$default" :as sh]
            ["term-size$default" :as term-size]
            ["zx$default" :as zx]
            ["zx$fs" :as zxfs]
            [nbb.core :refer [*file*]]))

(prn (path/resolve "."))

(prn (term-size))

(println (count (str (fs/readFileSync *file*))))

(prn (sh/ls "."))

(prn (csv-parse "foo,bar"))

(prn (zxfs/existsSync *file*))

(zx/$ #js ["ls"])

Call the script:

$ nbb script.cljs
#js {:columns 216, :rows 47}
#js ["node_modules" "package-lock.json" "package.json" "script.cljs"]
#js [#js ["foo" "bar"]]
$ ls


Nbb has first class support for macros: you can define them right inside your .cljs file, like you are used to from JVM Clojure. Consider the plet macro to make working with promises more palatable:

(defmacro plet
  [bindings & body]
  (let [binding-pairs (reverse (partition 2 bindings))
        body (cons 'do body)]
    (reduce (fn [body [sym expr]]
              (let [expr (list '.resolve 'js/Promise expr)]
                (list '.then expr (list 'clojure.core/fn (vector sym)

Using this macro we can look async code more like sync code. Consider this puppeteer example:

(-> (.launch puppeteer)
      (.then (fn [browser]
               (-> (.newPage browser)
                   (.then (fn [page]
                            (-> (.goto page "")
                                (.then #(.screenshot page #js{:path "screenshot.png"}))
                                (.catch #(js/console.log %))
                                (.then #(.close browser)))))))))

Using plet this becomes:

(plet [browser (.launch puppeteer)
       page (.newPage browser)
       _ (.goto page "")
       _ (-> (.screenshot page #js{:path "screenshot.png"})
             (.catch #(js/console.log %)))]
      (.close browser))

See the puppeteer example for the full code.

Since v0.0.36, nbb includes promesa which is a library to deal with promises. The above plet macro is similar to promesa.core/let.

Startup time

$ time nbb -e '(+ 1 2 3)'
nbb -e '(+ 1 2 3)'   0.17s  user 0.02s system 109% cpu 0.168 total

The baseline startup time for a script is about 170ms seconds on my laptop. When invoked via npx this adds another 300ms or so, so for faster startup, either use a globally installed nbb or use $(npm bin)/nbb script.cljs to bypass npx.


NPM dependencies

Nbb does not depend on any NPM dependencies. All NPM libraries loaded by a script are resolved relative to that script. When using the Reagent module, React is resolved in the same way as any other NPM library.


To load .cljs files from local paths or dependencies, you can use the --classpath argument. The current dir is added to the classpath automatically. So if there is a file foo/bar.cljs relative to your current dir, then you can load it via (:require [ :as fb]). Note that nbb uses the same naming conventions for namespaces and directories as other Clojure tools: foo-bar in the namespace name becomes foo_bar in the directory name.

To load dependencies from the Clojure ecosystem, you can use the Clojure CLI or babashka to download them and produce a classpath:

$ classpath="$(clojure -A:nbb -Spath -Sdeps '{:aliases {:nbb {:replace-deps {com.github.seancorfield/honeysql {:git/tag "v2.0.0-rc5" :git/sha "01c3a55"}}}}}')"

and then feed it to the --classpath argument:

$ nbb --classpath "$classpath" -e "(require '[honey.sql :as sql]) (sql/format {:select :foo :from :bar :where [:= :baz 2]})"
["SELECT foo FROM bar WHERE baz = ?" 2]

Currently nbb only reads from directories, not jar files, so you are encouraged to use git libs. Support for .jar files will be added later.

Current file

The name of the file that is currently being executed is available via nbb.core/*file* or on the metadata of vars:

(ns foo
  (:require [nbb.core :refer [*file*]]))

(prn *file*) ;; "/private/tmp/foo.cljs"

(defn f [])
(prn (:file (meta #'f))) ;; "/private/tmp/foo.cljs"


Nbb includes reagent.core which will be lazily loaded when required. You can use this together with ink to create a TUI application:

$ npm install ink


(ns ink-demo
  (:require ["ink" :refer [render Text]]
            [reagent.core :as r]))

(defonce state (r/atom 0))

(doseq [n (range 1 11)]
  (js/setTimeout #(swap! state inc) (* n 500)))

(defn hello []
  [:> Text {:color "green"} "Hello, world! " @state])

(render (r/as-element [hello]))


Working with callbacks and promises can become tedious. Since nbb v0.0.36 the promesa.core namespace is included with the let and do! macros. An example:

(ns prom
  (:require [promesa.core :as p]))

(defn sleep [ms]
   (fn [resolve _]
     (js/setTimeout resolve ms))))

(defn do-stuff
   (println "Doing stuff which takes a while")
   (sleep 1000)

(p/let [a (do-stuff)
        b (inc a)
        c (do-stuff)
        d (+ b c)]
  (prn d))
$ nbb prom.cljs
Doing stuff which takes a while
Doing stuff which takes a while

Also see API docs.


Since nbb v0.0.75 applied-science/js-interop is available:

(ns example
  (:require [applied-science.js-interop :as j]))

(def o (j/lit {:a 1 :b 2 :c {:d 1}}))

(prn (j/select-keys o [:a :b])) ;; #js {:a 1, :b 2}
(prn (j/get-in o [:c :d])) ;; 1

Most of this library is supported in nbb, except the following:

  • destructuring using :syms
  • property access using .-x notation. In nbb, you must use keywords.

See the example of what is currently supported.


See the examples directory for small examples.

8 Popular Websites That Use The Vue.JS Framework

In this article, we are going to list out the most popular websites using Vue JS as their frontend framework.

Vue JS is one of those elite progressive JavaScript frameworks that has huge demand in the web development industry. Many popular websites are developed using Vue in their frontend development because of its imperative features.

This framework was created by Evan You and still it is maintained by his private team members. Vue is of course an open-source framework which is based on MVVM concept (Model-view view-Model) and used extensively in building sublime user-interfaces and also considered a prime choice for developing single-page heavy applications.

Released in February 2014, Vue JS has gained 64,828 stars on Github, making it very popular in recent times.

Evan used Angular JS on many operations while working for Google and integrated many features in Vue to cover the flaws of Angular.

“I figured, what if I could just extract the part that I really liked about Angular and build something really lightweight." - Evan You
