How to Build a Server-Side Rendered Vue App with Nuxt.js

In this tutorial, I will be showing how to build a static website with Nuxt.js. For the purpose of demonstration, we’ll be building a personal portfolio website.

Usage of static websites are increasing in popularity recently. It’s not a surprise as static site generators seem to have been gaining more popular recently too. There are various static site generators which you can use to build websites. Some of these generators include Jekyll, Hugo, Gatsby, Nuxt.js to mention but a few. Gatsby and Nuxt.js are pretty new to the collection.

What is a Static Site

A static site is the simplest kind of website you can build. Static sites are written in HTML, CSS and sometimes little JavaScript. A static site contains little or no user interactions. They are stored in the filesystem of a server and are delivered to the user exactly as stored. The same information is displayed for all users. Static sites are suitable for the contents that never or rarely need to be updated, though modern static site generators are changing this.

Why Static Site

You might ask yourself why static site? Well, there are lot of benefits with using static site. These benefits includes and are not limited to the following:

Speed: This is the most obvious benefit of a static site as it is just HTML, CSS and JS files and some assets. There is no back and forth between the client and a server, hence it speed. Static sites can be served from a CDN.

Less Resources: Static sites uses less resources as things like servers and databases are not necessarily needed.

Security: You don’t have to worry of your servers been hacked or database vulnerabilities.

In addition to the above, there are various platforms that can help you with hosting your static site. These platforms includes: GitHub Pages, Netlify, Surge etc.

What is Nuxt.js

Nuxt.js is a framework for creating server-rendered Vue.js Applications. It was inspired by Next.js. Its main scope is UI rendering while abstracting away the client/server distribution. Nuxt.js comes with a lot of features to help you in your development between the client side and the server side such as asynchronous data, middleware, layouts, etc.

In addition to building server rendered applications, Nuxt.js can also be used to build static generated Vue.js applications (which will be our focus in this tutorial).

How it Works

In addition to using Vue.js, Nuxt.js uses the following libraries to create a rich web application development:

  • What is a Static Site
  • Why Static Site
  • What is Nuxt.js
  • How it Works
  • Create a Nuxt.js Project
  • Creating Master Layout
  • Creating Navbar Component
  • Creating The Homepage
  • Creating The About Page
  • Creating The Projects Page
  • Creating The Contact Page
  • Generating Static Site
  • Deploying Our Static Site]
  • Conclusion

All configured for you, so you don’t have to spend time installing and setting up these libraries yourself. Under the hood it uses Webpack with vue-loader and babel-loader to bundle, code-split and minify your code.

Nuxt.js tries to remain minimal as possible by keeping a total size of only 28kb min+gzip (31kb with vuex).

The image below shows a broad overview of how Nuxt.js works:

Let’s now build ourselves a static portfolio website with Nuxt.js.

Create a Nuxt.js Project

We’ll be using the starter template provided by the Nuxt.js team. We’ll install it using the Vue CLI, so you need to first install the Vue CLI in case you don’t have it installed already:

npm install -g vue-cli

Once installed, you can move on to creating Nuxt.js project with it:

vue init nuxt/starter portfolio

We can the project portfolio, you can name it whatever you like. Next, we need to install the dependencies:

cd portfolio
npm install

With the dependencies installed, we can now lauch our project:

npm run dev

The application is now running on http://localhost:3000. If everything went well, you should see a screen as the image below:

Before we dive in to code, let’s take a moment to define what our portfolio website will entail. The portfolio website will contain four (4) pages:

  • What is a Static Site
  • Why Static Site
  • What is Nuxt.js
  • How it Works
  • Create a Nuxt.js Project
  • Creating Master Layout
  • Creating Navbar Component
  • Creating The Homepage
  • Creating The About Page
  • Creating The Projects Page
  • Creating The Contact Page
  • Generating Static Site
  • Deploying Our Static Site]
  • Conclusion

Creating Master Layout

We’ll start by creating a master layout which all our pages will inherit. We’ll be using Bulma as our CSS framework. So we need to pull it into our project. To do so, open nuxt.config.js which is Nuxt.js config file and paste the code below within the link object that is inside the head object:

// nuxt.config.js

{ rel: 'stylesheet', href: 'https://cdnjs.cloudflare.com/ajax/libs/bulma/0.6.0/css/bulma.min.css' },
{ rel: 'stylesheet', href: 'https://fonts.googleapis.com/css?family=Source+Code+Pro:400,700' },

In addition to pulling in Bulma, we also pull in a Google font.

Within the layouts folder, there is a default.vue file. Open it and replace it content with:

<!-- layouts/default.vue -->

<template>
  <div>
    <nuxt/>
  </div>
</template>

<style>
  html {
    font-family: "Source Sans Pro", "Helvetica Neue", Arial, sans-serif;
  }
</style>

<nuxt/> will be replaced with the actual content of the page rendered.

Creating Navbar Component

Let’s create a navbar component, so we can add it to the master layout. Within the components folder, create a new Navbar.vue file and paste the code below into it:

<!-- components/Navbar.vue -->

<template>
  <div class="container">
    <nav class="navbar" role="navigation" aria-label="main navigation">
      <div class="navbar-brand">
        <a class="navbar-item" href="/">Portfolio</a>
        <button class="button navbar-burger">
          <span></span>
          <span></span>
          <span></span>
        </button>
      </div>
      <div class="navbar-menu">
        <div class="navbar-end">
          <nuxt-link class="navbar-item" to="/">Home</nuxt-link>
          <nuxt-link class="navbar-item" to="/about">About</nuxt-link>
          <nuxt-link class="navbar-item" to="/projects">Projects</nuxt-link>
          <nuxt-link class="navbar-item" to="/contact">Contact</nuxt-link>
        </div>
      </div>
    </nav>
  </div>
</template>

We can now add the navbar to the master layout. Open layouts/default.vue and update as below:

<!-- layouts/default.vue -->

<template>
  <div>
    <navbar></navbar>
    <nuxt/>
  </div>
</template>

<script>
  import Navbar from '../components/Navbar'

  export default {
    components: {
      Navbar
    }
  }
</script>

<style>
  html {
    font-family: "Source Sans Pro", "Helvetica Neue", Arial, sans-serif;
  }
</style>

Creating The Homepage

Within the pages folder, you will see an index.vue file. This file is what rendered when we navigate to the home route of our application. What Nuxt.js does is, generate routes based on the files in the pages folder. For instance, if we have index.vue, about.vue and contact.vue files within the pages folder, Nuxt.js will form the routes for the application as /, /about and /contact respectively.

Having said that, open pages/index.vue it and replace it content with the code below:

<!-- pages/index.vue -->

<template>
  <section class="section is-large">
    <div class="container has-text-centered">
      <h1 class="title">Hi, I'm Chimezie Enyinnaya</h1>
      <h2 class="subtitle">a Software Developer based in Lagos, Nigeria.</h2>
    </div>
  </section>
</template>

If we visit the home route again, we should see the new homepage in action:

Creating The About Page

Let’s now create the about page. Within the pages folder, create a new about.vue file and paste the code below into it:

<!-- pages/about.vue -->

<template>
  <section class="section is-medium">
    <div class="container has-text-centered">
      <h1 class="title">About Me</h1>
      <p>
        My name is Chimezie Enyinnaya (AKA mezie), I’m a self taught software developer based in Lagos, Nigeria. I build modern applications for the web! I'm a technical writer, I write technical articles and tutorials for various platforms including <a href="https://scotch.io/@mezie">Scotch.io</a>.
      </p>
    </div>
  </section>
</template>

Navigate to http://localhost:3000/about to see the about page in action:

Creating The Projects Page

In the same vein, let’s create the projects page. Within the pages folder, create a new projects.vue file and paste the code below into it:

<!-- pages/projects.vue -->

<template>
  <section class="section is-medium">
    <div class="container has-text-centered">
      <h1 class="title">My Projects</h1>
      <p>
        Some of my projects can be found on <a href="https://github.com/ammezie" target="_blank">GitHub</a>.
      </p>
    </div>
  </section>
</template>

Navigate to http://localhost:3000/projects to see the projects page in action:

Creating The Contact Page

Finally, we create the contact page. Within the pages folder, create a new contact.vue file and paste the code below into it:

<!-- pages/contact.vue -->

<template>
  <section class="section is-medium">
    <div class="container has-text-centered">
      <h1 class="title">Contact Me</h1>
      <p>
        You can follow me on Twitter: <a href="https://twitter.com/ammezie" target="_blank">@ammezie</a>
      </p>
    </div>
  </section>
</template>

Navigate to http://localhost:3000/contact to see the contact page in action:

We now have a functional portfolio website.

Generating Static Site

Now, we are going to generate a static site for the portfolio website which so far contains bunch of Vue files. To do this, we’ll make use of the nuxt generate command:

npm run generate

The command above will run nuxt generate which will in turn start building the application and generate the static files. Once the it done, you should now have a dist folder which contains the generated static files.

The nuxt generate command works by generating HTML files off the Vue files files within the pages folder for all the application’s routes.

Deploying Our Static Site

The final thing we’ll do is deploy the static site to a live server. For this we’ll be using Netlify, though you can use GitHub Pages or any other static site hosting. So head over to Netlify and sign up if you don’t have an account with them yet.

Once logged in, click the New site from Git button:

Then select your Git provider, I’ll be using GitHub. You will be directed to authorize with GitHub (in my case):

Once authorized, you will be redirected back and you will see a list of your GitHub projects which you can choose the one you want to deploy from:

Next, we need to specify a build command and a publish directory. For the build command we enter npm run generate which is the same command we used to build our files locally. Then we enter dist as the publish directory. Again, this is the same directory the generated files will be be.

Finally, click the Deploy site button to start the deployment.

Once the deployment is complete, Netlify will generate a random name with a URL for your application with which you can access the application. Mine is https://programmer-badger-66651.netlify.com

Conclusion

So in this tutorial, we looked at an overview of Nuxt.js. We also looked at why we might want to create static sites. Finally, we built a static website with Nuxt.js. As pointed out, Nuxt.js does more than just static site generation. You might want to go take a look at the docs to explore it more.

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.

NBB: Ad-hoc CLJS Scripting on Node.js

Nbb

Not babashka. Node.js babashka!?

Ad-hoc CLJS scripting on Node.js.

Status

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.

Requirements

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).

Usage

Install nbb from NPM:

$ npm install nbb -g

Omit -g for a local install.

Try out an expression:

$ nbb -e '(+ 1 2 3)'
6

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
"/private/tmp/test-script"
#js {:columns 216, :rows 47}
510
#js ["node_modules" "package-lock.json" "package.json" "script.cljs"]
#js [#js ["foo" "bar"]]
true
$ ls
node_modules
package-lock.json
package.json
script.cljs

Macros

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)
                                        body))))
            body
            binding-pairs)))

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 "https://clojure.org")
                                (.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 "https://clojure.org")
       _ (-> (.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)'
6
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.

Dependencies

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.

Classpath

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 [foo.bar :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"

Reagent

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

ink-demo.cljs:

(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]))

Promesa

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]
  (js/Promise.
   (fn [resolve _]
     (js/setTimeout resolve ms))))

(defn do-stuff
  []
  (p/do!
   (println "Doing stuff which takes a while")
   (sleep 1000)
   1))

(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

Also see API docs.

Js-interop

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.

Examples

See the examples directory for small examples.

How long does it take to develop/build an app?

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.

Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.

There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.

To give you an idea of how long the app development process takes, here’s a short guide.

App Idea & Research

app-idea-research

_Average time spent: two to five weeks _

This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.

All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.

Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.

The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.

The outcomes of this stage are app prototypes and the minimum feasible product.

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
