nw.js is a Node.js desktop application framework that combines a Chromium web renderer with a Node.js runtime to build standalone software for Windows, macOS, and Linux. It serves as a cross-platform desktop runtime that allows developers to create native executables using web technologies.
The project is distinguished by its integration layer that exposes Node.js system APIs and modules directly to the browser window and web worker contexts. It functions as a native module bridge, enabling the compilation and execution of low-level C++ system code and native addons within a web-based application.
The framework covers broad capability areas including desktop UI customization for managing system tray icons, application menus, and transparent windows. It also provides tools for application packaging and distribution, allowing web-based source code to be bundled into platform-specific executables. Additional capabilities include hardware permission management and source code protection.
