Feature Analysis by AI

The primary source of Efw was provided to AI for feature analysis. The explanation of data flow and security is helpful.

Client Feature Analysis

The primary objective of the EFW framework is to provide event-driven communication between the client (browser) and the server, along with the consequent automation of UI operations.

Server Feature Analysis

The Efw server-side acts as an event-driven middleware that accepts AJAX/WebSocket requests, starting from the client’s Efw("eventId") call. It leverages a powerful collaboration between Java and server-side JavaScript to seamlessly integrate authentication, validation, logic execution, and resource management.

Preview Feature Analysis

The purpose of the preview function is to enable direct display of files within the browser without forcing the client to download them. Its process focuses heavily on security and file size limitations.

Download Feature Analysis

The download function offers multi-functional download processing, including not only single-file download but also the capability to compress multiple files into a single ZIP archive and add password protection. The collaboration for this process, similar to previewServlet, occurs via server-side JavaScript (efw.server.js) and the session.

Upload Feature Analysis

The file upload process in the Efw framework is achieved through the cooperation of multiple components, spanning from client-side request construction to server-side rigorous security checks and persistence. This process is routed through a dedicated servlet (uploadServlet), distinct from regular event processing.

Summary of Security Features

The Efw framework provides a robust enterprise application environment by incorporating multiple, specific security checks at the layers of screen access, event execution, and file I/O.
