Tangbao DB Helper

MyBatis-style database helper for Node-RED that provides CRUD nodes, SQL mapper with template engine (dynamic parameters, conditionals, foreach loops), and multi-database support for MySQL (auto-installed mysql2) and SQLite (requires manual better-sqlite3 install). Current version 1.0.24 targets Node-RED 4.0+, Node.js 18+. Key differentiators: snake_case to camelCase mapping, runtime dynamic parameters via msg, and transaction support. Released under an unspecified license with no release cadence given; appears actively maintained for its niche but not widely used.
