A web application framework is designed to help the development of dynamic websites, web services, and web applications. Basically, a web application framework is a software framework. There are a number of frameworks available freely for use which provides access to a database, session management, and template framework, you may easily reuse the codes depending on your use.
Types of Architectures in Web Application Frameworks
There are so many web application frameworks available on the internet that runs on MVC pattern. There are five major types of architectures: component based, hybrid based, meta, request based and RIA based. Let’s have a short look on some architectures.
Model View Controller (MVC): As I stated earlier above that there are many frameworks which follow the pattern of Model View Controller (MVC), which easily separates data model from the user interface. This process helps MVC with promoting code reuses and modulations codes and also allows multiple interfaces which can be applied.
Push Based and Pull Based: There are some frameworks which required some actions to complete the processing which is known as Push based architectures. Ruby on Rails and Spring MVC are popular architectures which are push based. Those architectures which start with a layer and then pull results from other controllers when needs, these are pull based architectures but also known component based framework. Struts 2 and Strips are good examples of architectures using Pull based architectures.
Content Management Systems (CMS): When a higher level web application framework is taken with a big role it is called as Content Management Systems. There are some popular CMS available like Drupal and Joomla which provides minimal work where all functions are extended through modules. There will thousands on add-on modules available to be used with CMS and extends the use of a web application framework.
Features of Web Application Frameworks
Till now, we only discussed What is a web application framework and what are its types? Which clarifies only its basic and how it is made. Let’s have a short look at its features and what you can do with frameworks.
Web Template system in a Web Application Frameworks
All the dynamic pages run on the internet are actually a combination of static part (HTML) and dynamic part, the dynamic part is code which generates HTML. Now, this can be done through variables by using a template or optionally you can go through codes. Variables are referred as code in programming languages like PHP or ASP.NET, but in templates, you can use variables without using codes. To differentiate between HTML and variables, a syntax is made available while writing the codes. There are some engines which do not support this logic, so make sure whether it supports or not before you start your actual work.
Caching and security in Web Application Frameworks
In order to reduce the bandwidth use and load on the server we use caching of web documents which are opened in a browser, this is called Web caching. Usually, it copies the documents which pass while you browser pages on a website. Meanwhile, some frameworks come with authentications support which enables the web server to identify users of an application and restrict them to some area depending on the given functions.
Ajax in Web Application Frameworks
There are never ending frameworks available for each programming language and you can opt any one of them depending on your usage and also there are some tools available for creating and providing web services using a web application framework.
