@react-slot

react-slot brings Vue-style named slots to React for fine-grained component composition. The registry provides a single Slot.tsx component with Slottable, SlotPlaceholder, Template, and useSlots primitives, enabling parent components to inject content into named slots defined in child templates. No styling dependencies — pure React utility. Very small footprint. Free and open-source (MIT). Use for: building compound components or layout primitives that need Vue-like named slot composition when Radix UI's asChild pattern is insufficient for your composition needs.
