renderel

Renderel is a lightweight rendering library designed to render declarative templates into HTML or DOM nodes. It is intended for embedding in web applications and static page generators, providing a small, portable core that can be extended with plugins or adapters for different runtimes. The library emphasizes predictable updates and a straightforward API.

Core concepts include a minimal template syntax, a reactive data model, and a component system with lifecycle hooks. Renderel uses a diffing-based reconciliation engine to apply incremental changes to the output, aiming to minimize work during updates. It supports server-side rendering for initial HTML generation and client-side hydration for interactive pages. Accessibility considerations are part of its design guidelines.

Usage typically involves defining templates that bind to data sources and composing components into a scene graph. Mounting to a target container renders the initial output; subsequent data mutations trigger re-renders with selective DOM updates. The library offers integration points for state management, routing, and styling, as well as a small ecosystem of plugins and examples.

Renderel originated as a community project to explore lightweight rendering primitives and has seen contributions from developers across several regions. It is positioned as a core rendering solution rather than a full framework, and it competes with other minimal renderers by prioritizing simplicity and portability over feature breadth.
