SolidJS

SolidJS is a declarative JavaScript library for building user interfaces, currently stable at version 1.9.12, with a 2.0 beta release recently announced. It distinguishes itself from other UI libraries by compiling JSX templates directly to real DOM operations and fine-grained reactive primitives, avoiding a virtual DOM. This approach typically leads to excellent performance characteristics and a smaller bundle size. Solid focuses on explicit reactivity through signals, memos, and effects, providing granular control over updates without component re-renders. The project maintains a regular release cadence, primarily focusing on quality-of-life improvements and performance optimizations within the 1.x line, while actively developing the significant architectural changes and API re-evaluations slated for the upcoming 2.0 release.
