With the revolution of the information, an advanced version of the web proposed from web 1.0 to web 4.0. In each version, many web applications appeared. In the new versions, modern web applications (MWAs) proposed. These applications have specific features and different features, and these features made a new challenge for web engineering methods. The problem is that web engineering methods have limitations for MWAs, and the gap is that the developers cannot highlight the new features based on web engineering methods. In this paper, we extract features of the MWA based on web engineering methods. We extract web application modules for showing interaction and structure of their feature based on models and elements of web engineering methods. The result of this work helps the developers for designing MWAs through web engineering methods. Furthermore, lead to researchers to improve web engineering methods for developing MWAs features.
