With the increasing advent in SOA and RESTful based applications, all the business logic today is being pushed to the client. With numerable paradigms being present for the UI to consumes these services and create dynamic content, there becomes a need to define the presentation, structure and behavior of the User Interface.
While working with Brian Flanagan on a recent project, we came up with an architecture presentation to address this need, with an intent to help the business, customer, stakeholders and development team understand the architecture of UI/Front end development.
Good UX Means Good Business
In a world where technology is rapidly advancing and user expectations are rising, it’s no longer enough to have an average user experience; to delight your users and surpass your competition you must strive for the exceptional.
The Presentation Layer is mainly composed of CSS components, based out of an atomic design or BEM methodology. The CSS is typically written in either SASS or LESS (today’s most popular CSS pre-processors) and compiled to provide modular, scalable components, which is used to create the structural layer.
The behavioral layer introduces the business logic for our UI by consuming the RESTful services and creating dynamic content. This could typically include two-way data binding, ajax, MVC and Single Page Applications, all rendered on the client. There is an increasing number of frameworks to help us work with the business logic and the most popular one’s are Angular, Ember, Backbone, ReactJS among others. Note that selecting an appropriate framework is a very important task as each framework has its own pros and cons catering to different needs.
I hope this article explains the UI architecture and the underlying processes. Is this something similar you have seen implemented in your project/organization ? Are things being done differently or do you have another perspective on this ? Do let us know below.
