TypeORM
Code with Confidence. Query with Power. An ORM that supports DataMapper and ActiveRecord patterns for TypeScript and JavaScript.
Overview
TypeORM is a highly flexible and powerful Object Relational Mapper (ORM) designed for TypeScript and JavaScript applications. It allows developers to interact with various databases using an object-oriented approach, abstracting away raw SQL queries. A key differentiator is its support for both the DataMapper and ActiveRecord patterns, giving developers the freedom to choose the architectural style that best fits their project's needs and team's preferences. This flexibility, combined with its TypeScript-first design, ensures a high level of type safety and code predictability. The ORM boasts extensive multi-database support, including popular relational databases like MySQL, PostgreSQL, and MS SQL Server, as well as NoSQL options like MongoDB. Its powerful QueryBuilder provides an elegant and intuitive way to construct complex queries, handle relationships, and manage data with features like pagination and caching. TypeORM also includes robust support for database migrations, enabling developers to evolve their database schemas systematically and automatically. Furthermore, its cross-platform compatibility means it can be utilized in a wide array of environments, from server-side Node.js applications to client-side browser, mobile (React Native, Cordova), and desktop (Electron) applications, making it a versatile choice for modern development.
