Ruby on Rails is written in Ruby,  general-purpose programming language and dynamic in nature. Many clients and non-developers community often confuse the two, thinking Rails when hearing Ruby but rarely the other way around.

Ruby on Rails is a development tool, which provides web developers a framework. It offers a standard structure for all the codes, that developers write. It simplifies and provides abstracts over repetitive tasks, which becomes a supporting hand in developing new features for the web applications which has fast-changing requirements.

The primal role of Ruby on Rails development is convention over configuration. This helps the programmer, to spend less time configuring files in order to set up/initiate the development. Rails comes with a set of conventions which speeds up the development process to a different phase.

Another specific characteristic of Rails is to emphasis on RESTful app design. Here REST refers to(Representational State Transfer) a style of software architecture based around the client-server relationship. It encourages a logical structure within applications, which means they can easily be deployed as an API(Application Programming Interface).

So, why Ruby on Rails?

We could clearly see that Rails provides us a combination of the best tooling, better quality code libraries and a more realistic approach to software. Lets, take a look at its benefits!

Tooling: ROR offers fantastic tooling that helps developers to deliver more features in less time. It provides a typical structure for all web applications, where all repetitive tasks are taken care of on your behalf.

Code Quality:  Generally, we treasure the quality of third-party Ruby on Rails code to be significantly higher than Node JS or PHP web framework equivalents.

Test Automation — The Ruby community stands tall in testing and test automation. It is believed that it has precious value in helping to deliver good quality software and is one of the reasons the Ruby libraries are so preferable in the market.

Responsible Developers: We tend to find Ruby developers are more closely aligned around the strategy of responsible development. Anyone who is willing to develop a  small, to communicate well, tackle vertical slices and to write simple code over the smart code then one can find their project takes up a better shape with Rails engagement.

Productivity: Ruby on Rails is a powerful and succinct language, which when combined with the third party libraries, which allows one to enhance development features incredibly fast. Experts say it’s one of the most productive programming languages around the Globe.

Next Generation — Ruby on Rails seems to be the language of choice for a number of popular online code schools, such as Makers Academy, Steer and CodeCademy. 

The Process of programming is incredibly faster than other prevailing frameworks and languages,it’s because of the object-oriented tendency of Ruby and availability of a huge pool of open source codes within their own community.

Rails is an asset for Rapid Application Development (RAD), as the framework makes it easy to adopt changes.

Ruby on Rails code is readable and mostly self-documenting. It boosts productivity, as there is minimal need to write down a new documentation, makes it easier for other developers to have a ride on existing projects.

Pitfalls of Ruby on Rails!

It crawls!

One of the most frequent quarrel against RoR is its ‘slow’ runtime speed, which makes harder to rate your applications. While it’s true that other top frameworks and environment are somewhat faster than RoR, it is unlikely that your application will witness performance bottlenecks, unless it has a user base comparable to such large websites as Twitter.

In most cases,  your RoR application will face would be linked to the database architecture or web server and the proficiency of your developers rather than RoR itself. Performance issues should be still kept in mind, though. Twitter, for example, struggled to enhance RoR’s performance that deteriorated after the social media network became very fashionable. Although Twitter did not abandon RoR completely, it was forced to replace certain core communication components and server daemons with Scala solutions.

It has no Documents to refer!

 It can be hard to find good documentation for the less popular “gems”, and for libraries which make heavy use of mixins. Developers often end up finding the test suite playing the role of documentation and they have to rely on it to understand the behavior of the written code. This aspect isn’t bad in its essence, as the test suite should be the most up-to-date representation of the system; however, it can still be agitating having to leap into the code,  sometimes the written documentation pulls down our work much quicker. That’s why it is sometimes mentioned among the disadvantages of Ruby on Rails.

 It befriends Multithreading!

Rails supports multi-threading, though some of the IO (Input/Output) libraries do not allow, as they keep hold of the GIL (Global Interpreter Lock) for a quality execution. If developers don’t keep visiting frequently requests will get queued up behind the active request and can leas way to performance issues.  The knock-on effect of this is your application ends up consuming more compute resources than necessary, which can increase your infrastructure costs.

To sum up, Rails is a huge web app framework with a large number of built-in features. It can be used to create either small or large apps, but it tends to use more memory and resources than the other frameworks and performance can be a bit slower.

What is AngularJS?      

AngularJS is an open-source framework for developing front-end web applications based on Java scripts. It allows developers to use HTML template language and lets HTML syntax to express the application’s components briefly but precisely.

It is a featured JavaScript framework, with the dominant goal of simplification. It offers support in developing dynamic, single-page web apps and supports the (MVC) programming structure.

 What is Node JS? 

Node JS is a runtime library environment for building fast and scalable network applications. Node.js uses an advanced event-driven Industrial Organization model that makes it efficient and lightweight, perfect for real-time applications that are data-intensive, which run across distributed devices. 

Node JS is an open-source framework with cross-platform runover.Node.js applications are developed with JavaScripts based on a runtime to support on OS X, Microsoft Windows, and Linux.Node.js also renders an abundant resources of various JavaScript modules which supports in simplifying the development of web applications using Node.js to a huge extent.

 Let’s study much more about Angular JS and Node JS in detail….

AngularJS comes with a set of features that greatly reduce the amount of coding and effort involved to create an application becomes functional. It is also described Model-View-Controller(MVC) framework due to its simplified approach towards building an application.

Node JS extends developers to execute their code on the server-side. It offers a faster way to write scripts that are adaptable and uncomplicated. Developers can draft real-time applications and at the same time, it provides scope for mobile application development.

AngularJS contains more than a file. A core file is included by every application desires to use AngularJS since it contains major framework features. Additional files and modules can be added to the functionality built on top of a core feature.

Node JS can be utilized for the front end as well as for back-end development as it allows using the same JavaScript. Server-side capabilities are provided extensively in Node JS, a developer can listen to and reply to HTTP requests on the computer, hear out traffic network and simultaneously can access the database from the system directly. Node JS uses an event-based model to address scalability, and allow JavaScript libraries for JavaScript modules which simplifies the coding.

Angular JS is very useful in fabricating dynamic web applications. Developers working in  Angular JS platform uses HTML as the template language and its syntax is used to express the application’s component briefly. Its structure allows automatic and smooth data coordination between model, view, and components. AngularJS is easier to code, when it comes to one-page web-based templates are the same as the traditional plain HTML and include extended HTML terminology, which means that even a novice can straight away create applications with AngularJS.

Node JS such as Partial JS, Express JS,  etc. When it comes to developing fast and expandable server-side applications, Node JS is a clear-cut winner. Primarily, Node JS  extends JavaScript the ability to interact with I/O (input/output) devices over its APIs, and connect with other external libraries written in various other languages.

Angular JS provides the potential to build GUI (Graphical User Interface) for dynamic websites and web programs. Single-page applications are created smoothly using the AngularJS framework which allows writing custom HTML codes and integrating with other UI tools.

Basic Differences between Angular JS and Node JS:

AngularJS is a  perfect fit for long term projects, while Node JS is ideal for small term projects.

Angular JS can be added like any other java scripts, whereas Node JS must be installed on the system.

AngularJS is entirely created in Java script while Node JS is created in C, C++ languages along with java scripts.

Angular JS is the front-end framework when combined with PHP it can support in backend development while Node JS is simply a server -Side language.

AngularJS can support in developing real-time applications like chatting apps, whereas Node JS  can build collaborative apps like Google Docs & sheets.

Angular JS runs on the client browser, whereas Node JS runs on the webserver.

AngularJS is suitable for Chrome, Firefox, Safari, Internet Explorer and mobile-based browsers like Android OS, while Node JS is available for Linux, Microsoft Windows, and Mac OS.

Comparison Table: Angular JS Vs Node JS

Salient Features:

Angular JS:

• It is a framework written in Javascript language.
• It can manage the state of models.
• It Integrates with other UI tools.
• It easily manipulates DOM. (Document Object Model)
• It permits writing in custom HTML codes.
• It is meant for javascript developers to create dynamic web pages in a quick time.

Node JS

• Its runtime is  built on javascript engine in google chrome.
• It can be considered as a lightweight server which can serve client requests in a more simpler way than javascript can do.
• It performs communication operations with databases, web-sockets, middleware, etc.

To put in a nutshell,

Angular JS & Node JS both are open-source frameworks and dynamic by nature. Both frameworks are becoming popular platforms for development. It is wise to consult a  company providing web development services to ensure the integration is done right away.

Moreover, Data Binding in Angularjs consists of a couple of directives where everyone gets confused. Obviously, both have distant advantages and for diverse purposes altogether.

This article is completely designed to make you recognize the differences between them.

Ng-model

Ng-model or data-ng-model directive in Angular is the best way to bind the variables together. This is actually used as a two-way binding.

You will have an input component, and the value updated into that field must be reflected in other parts of the application. The better solution is to bind a variable to that field and output that variable wherever you wish to display the updated value throughout the application.

However, if you make any change in a single variable it can reflect in other places too. So the value must be updated in corresponding places as well!

This is actually achieved in case of using ng-model directive..!

To make it more clear, you can find the example here:


<script>
//Creating Angular Module
var helloApp = angular.module('helloApp', []);

//Creating Controller with Data
helloApp.controller(’employees Ctrl
‘, function($scope) {
$scope.search=”Enter Search Criteria”;
});
</script>
<body>
<!– Creating input component and attaching to ng-model –>
Search : <input type=”text” ng-model=”search”><br><br>
<b>Search Term:</b>{{search}}
</body>

In the above example, the variable “search” bound with an input component. When it is first assigned with a value using “$scope.search”, it is passing the value from a variable to the input component.

Later when the user updates the value in the field, expression {{search}} output the value from the input component to variable.

Ng-bind

This is different from ng-model. While ng-model is b-two-way binding, this is a single way binding used for displaying the value inside HTML component as innerHTML.

This directive is not only meant to be used with the HTML content but also to bind the component to HTML elements.

This directive is very valuable for updating the blocks like div, span, etc. with inner HTML content.

Let’s look at the complete example.


<!DOCTYPE html>
<html ng-app="helloApp" ng-controller="employees Ctrl">
<head>
<title>AngularJS - ng-model vs ng-bind</title>
<script src= "http://ajax.googleapis.com/ajax/libs/angularjs/1.2.26/angular.min.js"></script>
<script>
//Creating Angular Module
var helloApp = angular.module('helloApp', []);

//Creating Controller with Data
helloApp.controller(’employees Ctrl’, function($scope) {
$scope.search=”Enter Search Criteria”;
});
</script>
</head>
<body>
<!– Creating input component and attaching to ng-model –>
Search : <input type=”text” ng-model=”search”><br><br>
Search ng-bind: <input type=”text” ng-model=”searchBind”><br><br>
<b>Search Term:</b>{{search}}<br><br>
<!–Mapping input component–>
<span ng-bind=”search Bind”></span>
<!–Mapping directly to variable–>
<span ng-bind=”search”></span>

</body>
</html>

Happy Reading

“Programs must be written for people to read, and only incidentally for machines to execute”!!! This is what Angular JS exactly does. Angular JS renders top-quality features which make the user trouble-free to use.

In this article, we have listed out the top features of Angular JS version 6!

• Angular Elements
  
  • Single Page Applications: If you need them, Angular can be a perfect choice by just creating a  widget to the existing web page.
  • Web Component: This is possible by creating an Angular component and publish it as a Web Component, which can be used in any HTML page.

• Ivy Renderer
  • Enhancement: Ivy which is a new backwards -compatible Angular focuses on speed improvement, size reduction, and increased flexibility.
  • Reduced Code Size: Gzipps the code that would reduce the size of the code and make the compilation faster.

• Closure Compiler
  • Furl Optimizer: This high-end compiler generates smaller bundles and does a great job in dead code elimination when compared to Webpack and Rollup bundlers.

• Bazel Compiler:
  • Make Changes whenever needed: It doesn’t make sense to rebuild the whole application for each and every little change. Instead, we should only rebuild code that actually changed, and code that depends on those changes.

• Component Dev Kit
  • Responsive Web Design layouts: It eliminates the need for using libraries like Flex Layout or learning CSS Grid.

• Service Workers
  • Bug Fixes: This script which is running in the web browser fixes all the bugs which is one of the greatest features.

• Schematics
  • Artifacts: Angular CLI generates Angular artifacts using the technology called Schematics. This works perfectly when you decide to create your own template.

Final Thoughts

Group Angular is buckling down for the more current rendition of precise and it would be a noteworthy refresh. Angular 6 RC stage has started. Angular 6 stable adaptation ought to be discharged quite soon. According to the official calendar, Angular 6 will be discharged in the mid-April 2018. Angular 6 proceeds with an accentuation on being littler, quicker and less demanding to utilize enhanced the Web Development as it were.
