Most Important Frameworks For Javascript-based Websites And Apps?

If we talk about the framework, then first thing is to notice that there is a lot of frameworks available out there, allowing developers to choose the right to suit the task at hand. In these frameworks, some framework contains lots of features- which make developers work relevant for a full-blown application workflow.

Increasing the demand of the JavaScript, most of the JavaScript development is happening based on an MVC-style framework(model, view, Control). Some well known and famous framework that developers might consider is Backbone.Js, Ember.Js, and Angular Js. Each of these frameworks has its own building blocks and MVC style with JavaScript.

Backbone.js

Due to the availability of the models with key-value binding and custom events Backbone.Js gives structure to web applications.

Ember.js

It is built for productivity. It is also an Extremely rich templating system with composed views and UI bindings. It’s friendly API help us to work our job fast.

Node.js

Node.js is a platform built on Chrome’s JavaScript runtime for easily building fast and scalable network applications. Node.JS Website Development Services uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

AngularJS

It is a JavaScript framework from Google for application development. AngularJS is a toolset for building the advanced single page application (SPA) UI. It is fully extensible and works with other libraries. For a unique development, we can modify or replaced feature of AngularJS Website Development Services according to necessities for unique development.

In the last couple of years, JavaScript has made strides in mobile devices. Lots of features of mobile space are being developed using JavaScript. Using HTML5 and JavaScript, Cross Platform application can be developed with audio, video, and geolocation. If we talk about mobile browser then the latest mobile OS (Operating System) like android 4 and ios 5, have boosted the demand of JavaScript. The latest web apps called chrome beta release for Android 4 and iOS also further improves performance of web apps. This apps provides an impressive user experience and also fast.

JavaScript micro-libraries, like Zepto.js and jQuery mobile rapidly-expanding mobile-specific, helps the mobile developer to use JavaScript micro-libraries, that has been optimized for mobile and excludes irrelevant desktop operations.

Pros and Cons of using a framework:

When we use a well-known framework, it boosts the development process. Most of the framework are open source, which means we can update the code and develop according to our choice.

On the negative side, if we are not understanding or handle the framework correctly and we are still changing and updating then framework can be slow or it’s slow down the development process respectively.

Node.js Projects A New Outlook For Website Development

It is an acceptable fact that any web developers or the programmers prefer to develop simple and scalable web applications. And rightly, developers specify to adopt Node.js as their platform and millions of web applications run on this platform today. Hitherto, its adoption has doubled within a year as per the W3C survey.

Any developers ardent to develop web application prefer to adopt Node.js website development services for several reasons. The primary reason is that it empowers the front-end developers to write server-side code using JavaScript resulting in quick development with a small team (because it does not require a separate team for front-end and back-end developers). That is, in a straightforward manner, one can declare that Node has reexamined the approach to developing websites. Developers take days and not weeks to build critical functionality. This article intends to serve the beginners and numerous business-folk who still have not planned to adopt this platform for their websites.

Node.js web application is built in javascript including both the server-sides and client-sides as well. It uses an event-driven, non-blocking I/O model that makes it lightweight and proficient. It allows processing new requests without waiting for The response from backend SOA services. It is ideal for data-intensive real-time applications that run across varied devices. To add on to the list, mission-critical and revenue-critical systems deploy it. It is a runtime framework that exceptionally works to build next generation website namely APIs for mobile and web integration. The development team can utilize modules from pre-built libraries to develop their applications more rapidly(more than millions of free modules are available in the repository). It is very easy to install Node locally onto Windows, Mac or Linux PC and begin developing immediately.

Moreover, with Nodetime (an application performance monitoring and analytics service providing the solution for performance profiling, streamlining and troubleshooting) one can effectively analyze issues related to the execution of the applications.

However, it has a few demerits also. A few of them are as follows.

  1. It is single threaded using only a single CPU core and thus not recommended for heavy computation.
  2. Relational database tools are still in their early development stages and not as pleasant to work with.
  3. A node may not work in a shared web hosting.

Node.JS Web Development Company

In addition to web development, Node.js development services may provide awesome real-time experiences with Node. To mention a few, they are as follows:

  1. Gif chat room: Images from the camera during chat get processed and further sent to the chat room.
  2. Remote control of a car: Web interface is built on it to control the remote to control the car.
  3. It is able to stream the output of applications in real-time to web browsers and take input, over web sockets which means one can stream the games and play them in the browser.
  4. Collaborative drawing tool: Multiple people can draw on the same canvas, and, etc.

In brief, Node provides an exciting time for a web developer and acquired popularity among its community(Among Node.js Web Development Company).

NodeJS Hosting Tips – Creating a Multi Room Chat Client

https://www.facebook.com/plugins/post.php?href=https%3A%2F%2Fwww.facebook.com%2Fanika.leslie.31%2Fposts%2F416764308698813&width=500

Node.js is a platform built on Chrome’s JavaScript runtime for easily building fast, scalable network applications. Node.JS Website Development Services USA uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. NowJS is a framework built on top of Node.js that connects the client side and server side JavaScript effortlessly.

Image result for NodeJS Hosting

The core of NowJS functionality lies in the now object. The now object is special because it exists on the server and the client.

This means variables you set in the now object are automatically synced between the client and the server. Also server functions can be directly called on the client and client functions can be called directly from the server.

You can have a working HTTP server up and running in NodeJS with just a few lines of code. For example:

var http = require('http');

http.createServer(function (req, res) {

res.writeHead(200, {'Content-Type': 'text/plain'});

res.end('Hello Worldn');

}).listen(8080);

This little snippet of code will create an HTTP server, listen on port 8080, and send back “Hello World” for every request. That’s it. Nothing more needed.

Using NowJS, communication between the client and server side is just as simple.

Client Side:


In this code snippet, the client side sets a variable to ‘someValue’ and calls serverSideFunction(), which is declared only on the server.

Server Side:

everyone.now.serverSideFunction = function() {

console.log(this.now.clientSideVariable);

}

The server side is then able to access clientSideVariable, which is declared only on the client.

All the details such as establishing connections and communicating the change of data between the server and client are handled automatically by the framework.

In fact writing code using this framework is so simple, the NowJS hello world example is a working chat client and server written in under a dozen lines of code. Go check it out.

As a simple exercise to get comfortable with the NowJS API, we can modify the chat client example to support multiple chat rooms. Let’s take a look at how easy it is.

Server Side (multiroom_server.js)

1. The first thing we need to do is modify the distributeMessage() function to only send messages to users in the same chat room as the user.

// Send message to everyone in the users group

everyone.now.distributeMessage = function(message){

var group = nowjs.getGroup(this.now.serverRoom);

group.now.receiveMessage(this.now.name+'@'+this.now.serverRoom, message);

};

We store the name of the server room on the client side (this.now.serverRoom). When the client calls the distributeMessage() function we send the message to everyone in the same chat room by using getGroup() and using the group.now object instead of the everyone.now object. (everyone is just a group that contains all users connected to the server).

2. Next we need to handle the client changing chat rooms.

everyone.now.changeRoom = function(newRoom){

var oldRoom = this.now.serverRoom;

//if old room is not null; then leave the old room

if(oldRoom){

var oldGroup = nowjs.getGroup(oldRoom);

oldGroup.removeUser(this.user.clientId);

}

// join the new room

var newGroup = nowjs.getGroup(newRoom);

newGroup.addUser(this.user.clientId);

// update the client's serverRoom variable

this.now.serverRoom = newRoom;

};

The getGroup() method fetches the group object if it exists and creates a group if it doesn’t already exist. We use the groups addUser() and removeUser() methods to move the client from the old room to the new room.

That’s about it on the server side.

Client Side (multiroom.html)

3. First, we add a drop down with the list of server rooms.

Room 1
Room 2
Room 3


4. Next, we call the server side changeRoom() function when the user first connects and whenever the drop down is changed.

// on establishing 'now' connection, set the server room

now.ready(function(){

// By default pick the first chatroom

now.changeRoom($('#server-room').val());

});

// On change of drop down, clear text and change server room

$('#server-room').change(function(){

$("#messages").html(");

now.changeRoom($('#server-room').val());

});

5. For extra credit, we can allow the server to dynamically provide the list of rooms when the client connects.

The changes required would be

Server Side:

// Declare a list of server rooms

everyone.now.serverRoomsList = {'room1':'Room 1','room2':'Room 2','room3':'Room 3'};

Client Side:

now.ready(function(){

// Pick up list of chatrooms from server and populate dropdown

setServerRoomFromList(now.serverRoomsList);

// By default pick the first chatroom

now.changeRoom($('#server-room').val());

});

// populate the #server-room dropdown from a list

function setServerRoomFromList(roomList){

$('#server-room').empty();

$.each(roomList, function(key, value){

$('#server-room').

append($("").

attr("value",key).

text(value));

});

}

That’s really all you need to do. We now have a multi-room chat client/server with

i) A drop down on the client side with list of server rooms

ii) On connection with server, client auto populates server room list and enters the first room

iii) Changing drop down changes room

iv) Entering new room clears the screen for the user

This is obviously a fairly barebones version (like the original example), but it serves as a proof of concept of all the essential elements of NowJS communication to a Node.JS Web Development Company in USA.

Node Js Vs PHP – Challenges Faced by Web Developers

With the advent of Node.js in the web development arena, there has been an increasing speculation about its superiority over PHP, the most well-known programming language. Debates and discussions are rife regarding which is better for web development.

Every developer must try to develop at least a simple application in Node. This will enlighten you about the pros and cons, and also the latest updates about Node. PHP Website Development Services in USA has undergone a number of changes since its outset. A number of versions with improvements have been introduced. It is slowly transforming into a language developer actually need.

Increasing the Learning Curve:

No matter what stage of life you are at, Learning is an important and indispensable part of it. It helps you expand your horizons. Learning Node you will also get to know its abilities to enhance performance and solidarity both in your front-end and back-end code. This ensures better testing and code verification for an elimination of bugs.

There is no doubt that there are loads of open source PHP projects developed. However, it is also true that a number of projects have not been touched for years together.

Node.js is a new code developed by programmers who completely understand the modern web apps. Node.JS Website Development Services in USA varies from PHP in the sense that it enables you to present your logical processing to the client. This event-driven system ensures that the client is always kept updated. JavaScript has its own restrictions, but the modern language supports advanced syntax including closures. Whilst extending JavaScript you can transform it into an object configured as per your requirements.

Speed:

You can expect speed when working with Node as it is built on a computationally sound core system built considering modern web servers and their interactions. The node requires fewer CPU resources and can easily respond to the high number of requests in a short span of time.

There won’t be much difference in processing or event times if you have joined hands with Nginx, Varnish, Memcached, and PHP OpCache whilst using PHP. However, the multi-threaded setup of PHP will serve as a major barricade.

This is where Node really becomes a hit. When there are multiple connections, your server highly requires shifting to asynchronous and non-blocking, and, if any part of your code hinders then you will require a thread which involves a huge overhead both in terms of resources and speed.

With so many connections it is nearly impossible to go on creating threads for each connection. On the other hand, Node is non-blocking and asynchronous.

Gridlock:

To pass logic from one asynchronous call to the next Node makes use of Gridlock. This will ensure that new threads are safe from spawning. There is also no requirement for a deadlocked process. There is no function in Node which performs I/O. This implies that the process never blocks which is a major outcome of scalable systems.

Asynchronous:

With Node your code is totally asynchronous and if not handled appropriately, then you can end up with a callback refuge wherein you end up looping up into a callback chain.

SQL:

PHP and SQL are chums as they work in sync. On the other hand, Node serves as the powerhouse for JSON. SQL can be accessed by a number of plugins, but JSON is the basic language for communicating with a number of NoSQL databases. If you are going to work on a project requiring loads of SQL or you are not open to use NoSQL approach, then you may have to spend a lot of time in re-writing your query logic to enable your calls to support asynchronous blocks.

Segregation of Concerns:

PHP is the most impeccable language for a project. There are a number of frameworks with MVC structure, but there is nothing preventing you from churning out a file having some logic, database calls, and HTML output. It is not the same in the case of Node which segregates the fundamental components which give a clear classification of concern across controllers/routes, models and views.

In the end, I would only like to say that it is your choice. However, it would be better to learn something new than to go on with the customary. New technologies are always in demand and given the popularity of Node in Node.JS Web Development Company in USA you must try and hone your Node skills.
