ldfile is a vanilla JavaScript file loader helper that provides an easy way to load and process files from user input or URLs. It supports various file types including data URLs, text, binary, arraybuffer, blob, and blob URLs, and offers event-driven callbacks for handling loaded file content. This library is ideal for developers building web applications that require client-side file processing, such as file upload tools, document viewers, or any application needing to read and manipulate file contents directly in the browser.
