Which file types are NOT commonly used in Liferay development?

In Liferay development, the focus is primarily on web technologies that are essential for building user interfaces and enhancing user experiences. HTML files, CSS files, and JavaScript files are fundamental components of web development. They are commonly used within Liferay to create pages, style content, and add interactivity, which are crucial for developing themes and applications within the platform.

Executable files, such as those with the .exe extension, are not utilized in Liferay development. These files are typically associated with Windows applications and are not relevant to the creation of web applications or the deployment of features in a portal environment like Liferay. The Liferay framework leverages web standards, and executable files do not fit into this context, as they are intended for execution in a local operating system rather than serving content over the web.

Understanding the roles of different file types in web development is key. Liferay extensively employs HTML, CSS, and JavaScript, while executable files do not serve a purpose in the development and deployment of Liferay applications.
