TypeORM
A TypeScript and JavaScript ORM for Node.js with first-class MySQL and MariaDB support, alongside PostgreSQL, SQL Server, SQLite, and other dialects.
TypeORM supports both the Active Record and Data Mapper patterns, letting teams either call persistence methods directly on model instances or work through separate repository classes. It runs on Node.js as well as in the browser, Cordova, Ionic, React Native, NativeScript, and Electron, and works with both TypeScript decorators and plain JavaScript.
Its MySQL and MariaDB driver supports connection pooling, read replication, migrations generated from entity diffs, and a type-safe query builder. Released under the MIT license, it’s maintained by the TypeORM community and is one of the most widely used ORMs in the Node.js/TypeScript ecosystem.
