AJAX-DesignDeveloping any form of application always start with planning. Developers have to know the purpose of the application, its needed functions and how these functions will be implemented. It's even a practice especially for group projects to talk about the coding practices that should be followed in order to build a uniformed and ultimately stable application.
Without any of these considerations during the planning stage, developers will never be able to build an application on time. In a highly evolving business, time is always important and applications have to be released in a timely manner to avoid user frustration.
But even though the development approach on any application is still important on Ajax and JavaScript, there is a different route that some developers unknowingly choose. This selection is often based on how they will implement the functions of JavaScript and Ajax online.
There are basically two routes developers have to choose: first is on developing an application with pure JavaScript and; second is the development of the online application based on HTML while adding JavaScript functions. Either way, they do provide benefits but each of these functions also has their shortcomings.
The Pure JavaScript Approach
Developing an online application using only JavaScript or Ajax is always the developer's goal with regards to this programming language. JavaScript is a very challenging programming language and the ability to build one from the scratch without additional languages is often considered a great feat.
But as already indicated, pure JavaScript is often a very frustrating task for developers because of its difficulty. To be specific, the DOM approach when fetching information and interacting them to users is very challenging to implement. User expectations from the application might not achieve because the difficulty of DOM related functions.
The HTML + JavaScript Approach
While pure JavaScript is the difficult approach, using HTML on an online application with various integration of JavaScript functions is the easy route. In fact, this type of implementation is used by Google in YouTube.com. Developers simply create a small HTML-based websites and add JavaScript functions which will serve as tools.
The challenging part on the other hand is increasing security in this type of application. Developers who use HTML + JavaScript can be tempted to use basic libraries and widgets without checking its source or improving the security of the code. This practice increases the susceptibility of the online application to attacks.
Connecting to the Server for Data Purposes Only
These two approaches may have their disadvantages but they can easily improve with the right development practice. In developing pure JavaScript application, developers can use popular frameworks that can optimize the coding on their application. In HTML with JavaScript developers can easily optimize the functions they used from other sources.
But either way, a good practice that should be used by developers in a JavaScript or Ajax based application is to use the server as purely for data source. Using the server for additional purposes could open the server to various security attacks that can destroy the application.
