Panelre

Panelre is a term used to describe a modular framework for creating and managing panel-based user interfaces, especially dashboards and control panels. It is not tied to a single project; rather, several projects and libraries describe panel-based rendering concepts under the name panelre, or as a component of a larger framework. The central idea is to provide a structured approach to composing, arranging, and updating multiple panels within a single view.

Concepts and architecture: A panel registry maps identifiers to panel definitions. A layout engine computes positions and sizes for panels, supporting features such as drag-to-resize, reflow on window resize, and responsive behavior. A rendering pipeline updates the user interface when panel content changes or when panels are added, removed, or rearranged. Communication between panels can be event-driven, with a central event bus or shared state store.

Typical features: dynamic composition of panels, lazy loading and virtualized rendering for performance, theming and styling hooks, and extensible plugins to add new panel types or behaviors. Integration with existing UI frameworks (React, Vue, or vanilla JavaScript) is common, often via adapters or wrappers.

Adoption and limitations: Panelre remains a niche concept with no formal standard. Documentation and ecosystem are fragmented, and compatibility depends on the host framework. Use cases include dashboards, monitoring UIs, and data-analysis interfaces where multiple resizable panels are beneficial.
