MikroORM is a TypeScript ORM for Node.js based on Data Mapper, Unit of Work and Identity Map patterns.
MikroORM uses identity map in background so you will always get the same instance of one entity.
This is free and open source software.
Key Features
- Implicit Transactions – MikroORM allows handling transactions automatically. When you call em.flush(), all computed changes are wrapped inside a database transaction.
- DRY Entities – uses source code analysis so you do not have to repeat yourself when defining entities. Simply define correct TypeScript types and you are ready.
- Supports MongoDB, MySQL, MariaDB, PostgreSQL and SQLite databases, and more can be supported via custom drivers right now.
