AppJS

AppJS lets developers build mobile‑oriented web applications that behave like native desktop programs by leveraging familiar web technologies. It provides a Chromium‑based runtime, so HTML5, CSS3, and JavaScript code can access modern browser APIs without additional language learning. The library also integrates Node.js as a backend, enabling server‑side functionality and access to the extensive Node ecosystem.

The framework supplies a simple API for serving static files, routing requests, and creating application windows with configurable size and appearance. Event hooks such as “create” and “ready” allow developers to control window lifecycle and interact directly with the DOM, while built‑in support for Chrome DevTools aids debugging.

AppJS is distributed as a pre‑packaged bundle for Windows, Linux, and macOS, and can be installed via npm. It is open‑source, free to use, and positioned as a lightweight alternative for developers who want to reuse existing HTML, CSS, and JavaScript skills to produce cross‑platform desktop experiences.
