Fuseeruda

Fuseeruda is a lightweight development tool that integrates the Eruda JavaScript debugging console with the Fusee web-based engine. Its purpose is to provide mobile developers with in-page debugging and inspection capabilities for applications built with Fusee, without requiring desktop debugging setups. By embedding Eruda’s console and panels into a Fusee app, developers can inspect the DOM, view console output, monitor network activity, and profile performance directly on mobile devices.

The project originated within the Fusee community in the mid-2020s as a convenience for debugging WebGL and Canvas-based scenes on smartphones and tablets. It leverages Eruda’s modular plugin architecture to expose relevant Fusee runtime information, such as render timing and scene state, through familiar panels and tools.

Typical usage involves including the Fuseeruda integration in a Fusee-based web app and enabling the Eruda-powered debugging interface during development. It is designed to be opt-in and can be disabled in production builds to avoid unnecessary overhead or exposing debugging surfaces.

Limitations include reliance on mobile browsers that support Eruda, potential performance impact during heavy debugging sessions, and the need to keep the integration aligned with updates to both Fusee and Eruda. Fuseeruda is distributed under an open-source license and is hosted in repositories that connect Fusee development with the Eruda ecosystem.
