Lexical

Lexical is a minimal, extensible JavaScript text editor framework, engineered by Meta for superior reliability, performance, and accessibility.

This is the next-generation text editor core: a 22KB, dependency-free JavaScript framework built by Meta (formerly Facebook) as a replacement for DraftJS. It operates on a highly performant, state-based model, focusing on core editor functionality while offloading features like toolbars and rich-text components to a robust, plug-and-play plugin system. Lexical’s architecture is deliberately cross-platform, framework-agnostic (though it offers React bindings), and prioritizes WCAG compliance, making it a reliable choice for applications like Facebook, Instagram, and WhatsApp.
