Comparing 4 popular NestJS ORMs

NestJS, a widely-used Node.js server-side framework, offers compatibility with most Node.js libraries, including ORM libraries, to facilitate database interactions. Among the popular ORMs that integrate with NestJS are Sequelize, TypeORM, MikroORM, and Prisma, each with unique features and support for various database types. Sequelize, introduced in 2014, is known for its ease of use and supports the Active Record pattern, while TypeORM, released in 2016, offers both Active Record and Data Mapper patterns, making it flexible for both SQL and NoSQL databases. MikroORM, a newer addition from 2018, emphasizes the Data Mapper pattern and excels in transaction handling and performance optimization, whereas Prisma, launched in 2019, uses a schema definition language to generate strongly typed code, enhancing type safety and database tooling. Each ORM has its own strengths and use cases, and selecting the right one for a NestJS application requires considering factors such as project complexity, database requirements, and preferred design patterns.
