QuickLook Integration in a Tauri App — Native macOS File Preview
HiyokoKit's MTP file manager, built with Tauri, now includes QuickLook preview functionality. QuickLook is macOS's built-in file preview system that allows users to press Space on any file in Finder to preview images, PDFs, videos, and documents without opening separate apps. The integration uses the qlmanage command-line tool triggered from Rust via std::process::Command. For local files, the preview_file command spawns qlmanage -p with the file path, opening a native QuickLook preview window. For files on Android devices accessed over MTP, the flow downloads the file to a temporary location, previews it, then cleans up. The developer notes that QuickLook preview is table stakes for a macOS file manager—users expect it, and its absence makes the app feel unfinished. All tests were run on an 8-year-old MacBook Air, and the results come from shipping 7 Mac apps as a solo developer. This approach demonstrates how to bring native macOS behavior to cross-platform Tauri applications without relying on web-based previews.
