FileSaver.js is a client-side utility library designed to trigger browser download prompts for files generated within a web application or retrieved from remote web addresses. It enables the export of data directly to a user's local device, eliminating the need for server-side processing or backend infrastructure to handle file creation and storage.
The library functions as a wrapper for the browser Blob API, simplifying the process of encapsulating binary data and mapping it to temporary object URLs. By programmatically managing anchor elements and their download attributes, it simulates user interactions to initiate file transfers, allowing for the archiving of session-generated content and the retrieval of external resources.
The project provides functional utilities for managing the file lifecycle, including the ability to cancel active transfers. It supports a range of browser-based file management tasks, ensuring that data created or fetched during a web session can be saved locally through standard browser interfaces.
