For a proper understanding of UI software engineering, it is imperative that we begin with a detailed description of User Interface. In the digital industry, User Interface means every detail that the user may control or interact with across various devices -iMac, Macbooks, iPads, and mobiles.
Interface development, be it apps, websites, games or even simulators (in fact, especially the simulators), is a complex process that bears elements of design, engineering, and psychology. However, it is absolutely imperative that the end results if an easy to use interface that meets the desires of the end operator. In the bid to accomplish this, there has to be insight into the operator’s desires, expectations, mission, and approach. It becomes clear that when are versatile and conversant with all of the aforementioned disciplines, you will be much more proficient at creating a reliable and efficient interface. The major goal of the interface developer is to create a convenient interface, which would fulfill the user’s needs. To do this, you have to understand and identify the user’s strivings, goals, behavior patterns, and model scenarios of user’s interaction. The more cross-industry fields you are proficient in (analytics, psychology, marketing, user experience), the better solutions you will be capable of creating. One of the most important features of a UI developer is hinged on his ability to think rational and systematic way. It is expected that a UI developer has a fundamental understanding of the application of math and various tools to efficiently resolve challenges in the creation of a superb interface.
The contemporary engineering methods applied in web development is significantly different from the normal development procedure in certain areas. One of the foremost areas is concerned with the creation setting as well as page loading and efficiency concerns. With the benefits of NODE.js and NPM, the contemporary frontend engineer is only concerned with CLI when trying to create task instructions.
For a real-world project, if you use a twitter bootstrap, you may use 30–50% of its pre-built resources (HTML/CSS classes and JS plugins). The abandoned assets are then just garbage for your webpage or application weighing your page way more than actual page content. So, for the base cleanup, you must rely on the built tasks from NPM based Grunt, Gulp, Bower or Yeoman. As for example, a grunt package for concatenation of scripts and style files will convert all of your files into one. Grunt will also minify/uglify your CSS and JS file for fast loading page performance.
In short, while a typical frontend developer ignores page loading speed, usability, extra markup, CSS and JS garbase, a frontend engineer consider each of these issues way too seriously. A typical front-end developer can just learn HTML/CSS and jQuery and can then dive into the project. But a UI engineer can’t do that since a lot of factors are related to this term.
