pool-mysql

A MySQL connection pool wrapper with multiple pool support, async/await, connection tagging, and schema-based ORM-like query builder. Latest stable version is 2.2.14, released around 2022. It depends on the mysql package and provides features like writer/reader separation, model definitions with references (one-to-one, one-to-many), and populate queries. Key differentiators include environment-based configuration, priority/limit connection tagging, and a Schema class for defining columns with types like PK, FK, ENUM, Polygon, and DateTime. The library is TypeScript-typed and designed for Node.js, but its activity is low and may lack active maintenance.
