TypeORM

Mature ORM for TypeScript and JavaScript with Active Record and Data Mapper.

TypeORM is an open-source ORM for TypeScript and JavaScript that supports both the Active Record and Data Mapper patterns and runs on Node.js, browsers, and other JS runtimes. It provides entity decorators, migrations, relations, and a query builder across PostgreSQL, MySQL, MariaDB, SQLite, SQL Server, and more. It is notable as one of the longest-standing and most widely used TypeScript ORMs, including as the default ORM in NestJS projects.
