WEB APPLICATIONS AND TECHNOLOGIES

This course provides in-depth insights to the cutting-edge technologies that every modern web developer is supposed to master. After an initial high-level introduction of the protocols and patterns empowering the modern web, students will be guided to many of the technologies commonly involved in the development of rich web applications. Based on Javascript, the de-facto language for the web, the course will span from web-based middleware running on the Node.js runtime, NOSQL and in-memory databases, to front-end frameworks like the popular Google Angular and Twitter Bootstrap.
Finally, we discuss how web technologies are now effectively used for the agile development of software previously confined to native applications, like mobile applications and classical GUI programs for desktop environments.

After the course, the students will be able to:
- Understand the principles of the HTTP protocol
- Manage the user authentication in a web application
- Define and implement all the application requirements through REST-style APIs
- Implement full-stack solutions with common technologies of the Javascript ecosystem
- Implement hybrid application for desktop and mobile

Knowing the JavaScript programming language is a useful prerequisite although not strictly required. During the course, some of the most important aspects of the language will be summarized.

Development of a software project and a written essay that will be further discussed during an oral exam. The exam is designed to test the student ability to develop a modern web application and evaluate her/his understanding of the theoretical aspects related to web technologies.

The course is composed of frontal lessons, typically comprising practical case studies to better understand all the presented concepts and technologies.
Together with the referral texts, additional material will be provided by means of PowerPoint slides and source code.
