TypeORM is a TypeScript-first object-relational mapper for Node.js and other JavaScript platforms, supporting both Active Record and Data Mapper patterns. It works with PostgreSQL, MySQL/MariaDB, SQLite, SQL Server, Oracle, MongoDB, CockroachDB, SAP HANA, and Google Spanner, and includes migrations, a powerful QueryBuilder, transactions, and relation support.

Use cases

• map TypeScript entities to relational database tables
• manage database schema migrations in a Node.js app
• build complex SQL queries with joins and pagination via a query builder
• use the same ORM across PostgreSQL, MySQL, and SQLite
• model one-to-many and many-to-many relations with eager/lazy loading
• run transactions and connection pooling in an enterprise backend
• use an ORM in React Native or Electron apps

When to choose

• you want type-safe database models in a TypeScript project
• you need broad multi-database support from a single ORM
• you prefer a choice between Active Record and Data Mapper patterns
• you need first-class migrations and schema synchronization
• you're building NestJS or Express backends with relational data

When to avoid

• you need a lightweight query builder without entity mapping overhead
• your project targets Node.js versions older than 20
• you prefer Prisma-style schema-first workflows
• you need heavy NoSQL document modeling (MongoDB support is limited)
• you want minimal dependencies or a very small bundle
