React SQL Query Builder

React SQL Query Builder is a React-based component for building SQL query conditions via a visual rule tree. Version 4.2.0 provides a simple API to initialize a query builder with rules, fields, and operators, generating SQL WHERE clauses. It is not a managed UI component but rather uses imperative initialization with a DOM ID. The library is lightweight with no external dependencies, but lacks TypeScript definitions, ESM support, and active maintenance (last release over 2 years ago). It competes with react-querybuilder but offers a simpler tree-based rule structure, though with less flexibility and community support.
