react-vtree

A lightweight React component for efficiently rendering large tree structures (millions of nodes) built on top of react-window. Current stable version is v3.0.0 (released 2023), which requires React 18+. Release cadence is irregular; v3.0.0 consolidated changes from a long beta, with v4.0.0 planned. Key differentiators: uses a generator-based treeWalker for flexible tree building, supports both fixed-size and variable-size items, and ships TypeScript definitions. Alternatives like react-virtualized-tree are heavier or less maintained.
