TypeORM is an ORM (Object-Relational Mapper) that can run in Node.js, browsers, Cordova, Ionic, React Native, NativeScript, Expo, and Electron platforms, and can be used with TypeScript or JavaScript. It supports both DataMapper and ActiveRecord design patterns, provides a QueryBuilder for building complex queries, and offers first-class support for database migrations and schema generation. It works with multiple databases including MySQL, PostgreSQL, MariaDB, SQLite, MS SQL Server, Oracle, MongoDB, CockroachDB, Google Spanner, and SAP HANA.
What it's for
defining database entities with TypeScript decoratorsbuilding complex queries with joins, pagination, and cachingrunning database migrations with automatic generationusing Active Record or Data Mapper patterns for database interactionworking with multiple databases and data sources in one applicationstoring tree structures using Adjacency list and Closure table patternswriting parameterized SQL queries via a SQL tag helper
