Designing of Large Scale JavaScript Application Part 4

In the previous article we have seen that Modular approach is best suite for a big application. Designing of modules are crucial part for large scale application but one thing that is pending is How different modules can inteact with each other. The important point we suggest is to make the modules less dependent, loosly coupled, etc etc. butHow?

Designing of Large Scale JavaScript Application Part 3

The basic definition of a Module is 

Modules are an integral piece of any robust application's architecture and are typically single-purpose parts of a larger system that are interchangeable.

Designing of Large Scale JavaScript Application Part 2

Here I am continuing the discussion that we made in the previour article Designing of Large Scale JavaScript Application .

Things you need to forget…… actually need to relearn

• Forget the way you write JavaScript earlier, no more thousands of lines of code in single file.
• Forget the way you declare variables in globally, try to learn the way you declare in C# or JAVA or any server-side OOP platform
• Forget the way you use jQuery.

Designing of Large Scale JavaScript Application Part 1

Introduction

I'm currently a developing a UI centric application, for that I am working on the front-end architecture that supports the growing functionalities and pretty maintainable for the its next generations. Right now I have a basic idea of the platform and only an idea of the applications which is both complex and often require an architecture that is scalable and highly-reusable. The complex logic is implemented in JavaScript that communicates with server asynchronously.

Communication Technologies For .Net Applications

• 
    ASMX, also called ASP.NET Web Services, would be an option for cross platform communication like with the Java EE-based application others across the Internet. Given that Web services are widely supported today, this would likely be the most direct way to achieve cross-vendor interoperability.

Middleware communication support of .NET

Communication between different applications and processes is a necessity for sharing resources, Business logics and data. Networking solutions enabled PCs to be able to communicate with each other and share resources such as printers and disks, applications needed to be able to send and receive data and coordinate their actions with other applications running at the same time on other computers. Many common inter-process communications mechanisms were available, such as named pipes and sockets. These mechanisms were very low-level and using them required a good understanding of how networks work. But for rapid development we have to rely on the available frameworks that have stable, scalable and secured design and already tested under various scenarios.

It is generally required to trigger an event when user press enter in the text box. Well this is very much simpler as, bind keydown event of jquery and check for keycode 13 that is if enter is pressed.

Working with DropDownList with MVC and KnockoutJs to limit the data posted on the server efficient way

Working with Knockoutjs and MVC makes our life easy, but still there are some points that require some special attention.

And one of these points is How much data is posted back to the server when we make a async call? Well it is obviously not required for very small application that target very limited users that are using very high connectivity with the server. but most of the application are not like that. In general we have to take care of such things to make our application more reliable and scalable. Quick reference to the issue i have observed in many applications.
