Here’s what makes ReactJS a better option for building your next Web Application.

AngularJS Development - Why Choose AngularJS For Web Development?

AngularJS Development - Why Choose AngularJS For Web Development?

AngularJS is the most popular framework for web development and nowadays more in demand. We explain in-details why choose AngularJS for web development for your next project?

AngularJS is a web development framework based on open script languages like JavaScript, hypertext markup language and cascading style sheet.
Web development has become an integral part of the marketing world over a period of time. We can't imagine the marketing world without advertisement that is framed virtually or shopping webpage which had made the life of people so much easier.
So, designing a webpage that gives good user experience and has flexible applications are the current requirements of the marketing world.
AngularJS development company has been revolutionary in the web development field. Web developers are constantly utilizing AngularJS to build a vibrant and flexible application.

Here, we would be going through a certain point which would be acknowledging the fact as to why AngularJS should be utilized in web development.
It is one of the most popular web development applications. So, let's glance over certain points. Why?
Certain problems that are tackled by the AngularJS
Imaging, where you are interrupted every time you select a different task on a webpage because the page is refreshed automatically every time. So, this process becomes kinda tedious and most-importantly time-consuming.
This problem is eradicated with the use of AngularJS.
The master language that is utilized by AngularJS as a default language is HTML.
The AngularJS has the ability to support a wide array of functions. A variety of functions can be created on AngularJS without any issues of support. And secondly, it offers certain additional features as well like dependency injection, simple architecture, convenient testing, and parallel development.

1. High Performance
Robustness of web development is what sets this feature apart.
It is powered with a wide horizon of features like filters, data binding, animations, API, scope management, clients, directives, form validation, content sanitation and many more.

2. User Interface
As I have stated earlier the master language that has been set as a default language for AngularJS is HTML.
So, this language creates a good user interface. So, it has automatically sorted one of the biggest hurdles faced during web development which is designed user-friendly flexible apps.

3. Data Binding
Changes made in the modules are quite highlighting in it. So, these features make it more dependable in the market.

4. Filters
They are an integral member or part of any data development features. This added feature helps in creating variations in the web application.
For example, you can use uppercase and lowercase features while present large data to the user.

5. Use Of MVC
AngularJS makes use of features like MVC for the purpose of web application development. MVC stands for the model view controller.
Now, if we break down MVC into three segments that it would be quite easier to understand it. The first segment that is taken into consideration is model designing where all the work related to model development and maintenance is carried out.
Second is the view portion where its sole purpose is only to view the data. And the last segment is the controlling portion which is a linking string between the two components.

6. Testing
It is an important step in any web application development process.
So, the employment of the AngularJS web application, web development has made it quite efficient. It comes with a set of unit test runners that carry out the testing procedure at each and every step of the web development process.
So, it gives you can approximate rough idea as to how the web application is going to perform in the near future.

So, these features set the AngularJS web development application apart from the others. No doubt, it is one of the most demanded web development applications present in the market out there.
Well, if you are a newbie in the web development arena, then you don't have to stress over the fact. There are certain web developers companies that can assist you in the web development process using AngularJS web development.

7. Declarative Code Style
Declarative paradigm is mainly utilized in AngularJS to create patterns while building a web application program.
The main purpose of using declarative code style is to make program code easier, lightweight and decipherable.
Spa features of AngularJS
Validation capabilities are provided along with the AngularJS.
It handles the error-handling issues with its validation capabilities.

8. Easy To Use
With the horde of features provided by the AngularJS, it becomes easy to use.
And because it uses the MVC model in its web development procedure hence it becomes quite easy to use. It minimizes the need to write the code. Secondly, it has an extensible feature as well where HTML can be turned into XML, which makes it more demandable.

Whenever you want to make logistics in the web development, you can always opt for this added feature in the AngularJS. It improves code readability.
So, one could always seek out for AngularJS development services to get their work done without any hassle.

Reactjs vs. Angularjs — Which Is Best For Web Development

Reactjs vs. Angularjs — Which Is Best For Web Development

In this article we will discuss full details and comparison of both Reactjs and Angularjs

Everyday web development technology emerges like a skyrocket. Technology is evolving, and web applications usage is increased vastly in the last few years. JavaScript is one of the language to build web applications in an extended way.

At the same time, some of the famous companies introduced Web development frameworks for JavaScript to add more enhanced features to the web development world.

Well known Social media giant Facebook, created the ReactJS framework. And search engine giant Google is owned and built a platform called AngularJS. Both are used to develop web applications with excellent user interface and experience.

Web developers or Upcoming web developers.

Letus deep dive into the ReactJS vs AngularJS, I mean to say it is like Google vs Facebook (just for fun).

1. What is ReactJS?

ReactJS is a JavaScript library and it used to build the Web-applications with great UI experience. It is also referred to as cross-platform. The social media giant *Facebook *is created ReactJS. It is used to develop mobile applications and web applications.

ReactJS Advantages

Here are the advantages of ReactJS framework

JSX

JSX referred to as JavaScript XML and it is an extension to the JavaScript language extension. A path to rendering the structure component using JScript syntax is easy. And it is native to many developers. Similar to HTML, JSX is also contains tags, attributes

React Dom Render

This method especially used to interpret or render HTML elements. It will use in the form of “ReactDOM.render()”

Babel

Babel is also called JavaScript, and it can interpret programming or markup languages into JavaScript.

Sample ReactJS example code and integrated with the HTML and JavaScript languages. JSX, Dom render, Babel code’s are explained below.

<!DOCTYPE html>
<html lang="en">
   <head>
      <title>ReactJS elements testing</title>

      <!-- Application interface loaded here -->
      <script src= "https://unpkg.com/[email protected]/umd/react.production.min.js"></script>

      <!-- Load React DOM-->
      <script src= "https://unpkg.com/[email protected]/umd/react-dom.production.min.js"></script>

      <!-- Load Babel Compiler -->
      <script src="https://unpkg.com/[email protected]/babel.min.js"></script>
   </head>
   <body>

     <div id="myID">Hello, ReactJS World!</div>

     <div id="myID01">Hello World!</div>

     <script type="babel/text">

     <!--ReactDOM render code goes here-->
     ReactDOM.render(

       <h1>Hello, ReactJS Framework!</h1>,

       document.getElementById('myID'));

     </script>

     <script type="text/babel">
     <!--JSX Babel code goes here--!>
     const name = 'Yogesh makeitweb';

     ReactDOM.render(

       <h1>Hello {name}!</h1>,

       document.getElementById('myID01'));

     </script>
 
  </body>

</html>

2. What is AngularJS?

AngularJS is an open source and structural framework. It is also called MVC (Model View Controller) *Framework *which is the same as the JavaScript framework. And it is especially used to build high interactive web applications with great user experience.

AngularJS framework Universal Syntax code,

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>

AngularJS helps you to create HTML language with HTML attributes referred to as AngularJS directives. And these are provided functional capabilities to the HTML applications. This framework provides user-defined and built-in directives.

AngularJS Directives

AngularJS framework uses {{}} double braces as place holders for data. This framework adds extend support to HTML language with ng-directives.

There are 3 types ng-directives

  • **ng-app: **It is referred to an AngularJS application
  • **ng-model: **It binds the value of HTML controls viz textarea, select, input to HTML application data.
  • **ng-bind: **It is especially used for the HTML final outputs and binds the application data to HTML view.

Sample AngularJS example code

<!DOCTYPE html>
<html>
   <head>
      <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
   </head>
   <body>

     <!--div tag is the ng-app directive, and it is the owner of total angularJS application-->

     <div ng-app="">

       <!--name tag is the ng-model directive and it will create input field to the entire application-->

       <p>Name: <input type="text" ng-model="name"></p>

       <!--ng bind directive will bind the paragraph element to the name field as shown below-->

       <p ng-bind="name"></p>

     </div>

  </body>
</html>

3. Key Differences
  • ReactJS supports uni-directional and Data binding. AngularJS supports Bi-directional data binding
  • AngularJS is more scalable and versatile compared to ReactJS.
  • AngularJS enables both Integration and unit testing, but in ReactJS is only enables Unit Testing only.
  • ReactJS code is very easy and simple to understand, but on another side, AngularJS code is very difficult because of third-party libraries and syntax.
  • ReactJS is perfect for large model web applications, perhaps AngularJS is not much convenient to built large models.
4. Comparison of Angular vs React: Basic Comparison

Here is the Below image shows, the interest of these frameworks over the last 5 years

5. Popular web applications Based on AngularJS and ReactJS

6. Conclusion

In today’s technology world, React, and AngularJS defined as significant web development frameworks.

While selecting the best framework for web applications is up to the requirement of use and needs, scalability and long term success. However, it’s in your hands to do some on React and Angular before choosing the best one.

Perhaps one thing we should mention here AngularJS popularity is decreasing over time compared to ReactJS.

React Web Development: A Guide to Develop Progressive Web Applications

React Web Development: A Guide to Develop Progressive Web Applications

Outperform your competition with progressive web development and React.

Progressive web applications (PWAs) quickly gained popularity because they are web performance applications based on fast performance, streamlined to provide a mobile app-like experience. PWAs are built using HTML, CSS, and JavaScript to create a level of availability and performance equivalent to that of native mobile applications. They respond quickly, consume less data, store more space, and support push notifications and offline use in the browser.

Building a progressive web application has now become the web development trend that every business wants to follow. Significant players like Twitter and Flipboard have recently rolled out their progressive web apps to provide a mobile experience for users, without requiring them to install the app. In this article, you will learn how to build a progressive web application using React. Let's get started.

Step One — Set up the React Application

First, create a React application with create-react-app. To do so, you need to run the following commands:

  • npm install -g create-react-app
  • create-react-app pwa-app

Now, install React Router:

You need to replace the content of src / App.js using the code below to get a basic template with navigation.

import React, { Component } from 'react';
import { Router, browserHistory, Route, Link } from 'react-router';
import './App.css';

const NavBar = () => (
<div className="navbar">
<Link to="/">Feed</Link>
<Link to="/profile">Profile</Link>
</div>
);

const Template = ({ title }) => (
<div>
<NavBar />
<p className="page-info">
This is the {title} page.
</p>
</div>
);

const Feed = (props) => (
<Template title="Feed"/>
);

const Profile = (props) => (
<Template title="Profile"/>
);

class App extends Component {
render() {
return (
<Router history={browserHistory}>
<Route path="/" component={Feed}/>
<Route path="/profile" component={Profile}/>
</Router>
);
}
}
export default App;

Now, you'll have to update the default styles by replacing your src/App.css with the styles below to make your application look clean.

.navbar {
background-color: #01C8E5;
text-align: center;
}

.navbar a {
display: inline-block;
padding: 10px;
color: #fff;
text-decoration: none;
}

.page-info {
text-align: center;
font-weight: bold;
}

Then, run npm start to test the application in the browser. It is basically an application with two routes. Now, you will convert it to PWA.

Step Two — Lighthouse Setting and Auditing

Lighthouse is an automated open-source tool for testing applications against PWA checklists. It facilitates audits for accessibility, performance, and more.

Check your application with Lighthouse. Click the Lighthouse icon from the top right corner in Chrome and then click the "Create Report" button. The generated report will look like this:

Creating a report to test your PWA with Lighthouse

Fix all failed audits.

Step 3 — Sign Up for a Service Staff

Service employees are proxy servers that connect the application and the network. With Service Worker, you will have to block network requests and save cached files. It allows your application to work even with an unavailable system.

Create an empty worker.js file in your application's general directory and add the following code to that file.

// Flag for enabling cache in production
var doCache = false;

var CACHE_NAME = 'pwa-app-cache';

// Delete old caches
self.addEventListener('activate', event => {
const currentCachelist = [CACHE_NAME];
event.waitUntil(
caches.keys()
.then(keyList =>
Promise.all(keyList.map(key => {
if (!currentCachelist.includes(key)) {
return caches.delete(key);
}
}))
)
);
});

// This triggers when user starts the app
self.addEventListener('install', function(event) {
if (doCache) {
event.waitUntil(
caches.open(CACHE_NAME)
.then(function(cache) {
fetch('asset-manifest.json')
.then(response => {
response.json();
})
.then(assets => {
// We will cache initial page and the main.js
// We could also cache assets like CSS and images
const urlsToCache = [
'/',
assets['main.js']
];
cache.addAll(urlsToCache);
})
})
);
}
});

// Here we intercept request and serve up the matching files
self.addEventListener('fetch', function(event) {
if (doCache) {
event.respondWith(
caches.match(event.request).then(function(response) {
return response || fetch(event.request);
})
);
}
});

Now, check if the browsers support service staff and then register worker.js. To do this, you need to add the following script to the file public/index.html (note that shrink-to-fit=no in the viewport meta tag has been deleted).

<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="theme-color" content="#000000">
<link rel="manifest" href="%PUBLIC_URL%/manifest.json">
<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
<title>React App</title>
</head>
<body>
<noscript>
You need to enable JavaScript to run this app.
</noscript>
<div id="root"></div>
<script>
if ('serviceWorker' in navigator) {
window.addEventListener('load', function() {
navigator.serviceWorker.register('worker.js').then(function(registration) {
console.log('Worker registration successful', registration.scope);
}, function(err) {
console.log('Worker registration failed', err);
}).catch(function(err) {
console.log(err);
});
});
} else {
console.log('Service Worker is not supported by browser.');
}
</script>
</body>
</html>

You must restart your application and reload the browser after which you will see the Successful registration of member workers on the developer console. Now, recreate the Lighthouse report.

Step 4 - Improve the Progressive Nature of the Application

Your application will display an original blank div until the JavaScript loads and React hooks the original route. You must make sure your application works without downloading JS and displaying a bit of CSS and HTML before React takes effect. Your updated Index.html will look like this:

<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<meta name="theme-color" content="#000000">
<link rel="manifest" href="%PUBLIC_URL%/manifest.json">
<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
<title>React App</title>
<style type="text/css">
body {
margin: 0;
padding: 0;
font-family: sans-serif;
}
.navbar {
background-color: #01C8E5;
text-align: center;
}
.navbar a {
display: inline-block;
padding: 10px;
color: #fff;
text-decoration: none;
}
.page-info {
text-align: center;
font-weight: bold;
}
</style>
</head>
<body>
<noscript>
You need to enable JavaScript to run this app.
</noscript>
<div id="root">
<div class="navbar">
<a href="/">Feed</a>
</div>
<p class="page-info">
Loading an awesome app...
</p>
</div>
<script>
if ('serviceWorker' in navigator) {
window.addEventListener('load', function() {
navigator.serviceWorker.register('worker.js').then(function(registration) {
console.log('Worker registration successful', registration.scope);
}, function(err) {
console.log('Worker registration failed', err);
}).catch(function(err) {
console.log(err);
});
});
} else {
console.log('Service Worker is not supported by browser.');
}
</script>
</body>
</html>

Now, use Lighthouse to retest your application, and you'll see an improvement in the performance of the application.

Step 5 - Add the Splash Icon

You are required to add a 512x512 icon to display on the screen. To do so, you will have to update the manifest.json file and add the t0 icon to the public directory.

{
"short_name": "React App",
"name": "Create React App Sample",
"icons": [
{
"src": "icon-192x192.png",
"sizes": "192x192",
"type": "image/png"
},
{
"src": "icon-512x512.png",
"sizes": "512x512",
"type": "image/png"
}
],
"start_url": "/",
"display": "standalone",
"theme_color": "#000000",
"background_color": "#ffffff"
}

Also, use the following meta tags to allow the browser to determine that your application is a PWA.

<!-- Tell the browser it's a PWA -->
<meta name="mobile-web-app-capable" content="yes">
<!-- Tell iOS it's a PWA -->
<meta name="apple-mobile-web-app-capable" content="yes">
Step 6 — Implement PWA

Now, only HTTPS is missing, and the cache can be fixed after you deploy the application. Update the doCache flag with true in the worker.js file. Create a new project in the firebase dashboard and name it "Pwa Application." Then, run the following command in the project directory:

npm install -g firebase-tools
firebase login
firebase init

Your Firebase.json will look like this:

{
"hosting": {
"public": "build",
"rewrites": [
{
"source": "**",
"destination": "/index.html"
}
]
}
}

After initializing, building and deploying your application.

  • npm run build
  • firebase deploy

You will see results after you test the application using Lighthouse on the deployed URL.

Final product with Lighthouse

Finally, you have created your first progressive web application with React.js!
