Prisma on the other hand generates a lightweight database client that exposes a tailored and fully type-safe API to read and write data for the models that are defined in the Prisma schema, following the DataMapper ORM pattern rather than Active Record.

With the Active Record ORM pattern, TypeORM's approach often leads to complex model instances that are becoming hard to maintain as an application grows. Prisma models are defined in the Prisma schema while TypeORM uses classes and experimental TypeScript decorators for model definitions.

implicit handling of relation tables (also sometimes called JOIN, link, pivot or junction tables) ( docs).

intuitive modeling of relations in the data model via relation fields ( docs).

creating nested TypeScript typings based on models and their relations ( docs).

easy and type-safe querying of nested data without worrying about JOINs ( docs).

applying filters on related records ( docs).

nested writes that enable updating/creating connected records ( docs).

traversing relationships via the fluent API ( docs).

Prisma's concept of virtual relation field enables an intuitive and convenient way for application developers to work with related data. Working with records that are connected via foreign keys can become very complex in SQL. You can learn more about both approaches in the Pagination section of the docs or in the API comparison below. TypeORM only offers limit-offset pagination while Prisma conveniently provides dedicated APIs for both limit-offset but also cursor-based. While TypeORM primarily provides the filter based on the ILike operator which comes directly from SQL, Prisma provides more specific operators that developers can use, e.g.: contains, startsWith and endsWith. It should also be noted that, as explained in the type-safety section below, TypeORM looses type-safety in for filter queries in many scenarios.ДЄ good example of how the filtering APIs of both TypeORM and Prisma differ is by looking at string filters. Prisma on the other hand, provides a more generic set of operators that are intuitive to use. TypeORM primarily leans on SQL operators for filtering lists or records, e.g.

The following sections examine a few examples for how Prisma's and TypeORM's APIs differ in certain scenarios and what the rationale of Prisma's API design is in these cases.

While Prisma Client operates on a higher-level of abstraction, it strives to expose the full power of the underlying database and lets you drop down to raw SQL at any time if your use case requires it. Prisma's API design heavily leans on the idea of making the right thing easy. TypeORM is closer to mirroring SQL in its API while Prisma Client provides a higher-level abstraction that was carefully designed with the common tasks of application developers in mind. TypeORM and Prisma operate on different levels of abstraction. CRUD queries are provided by Prisma Client, a lightweight and entirely type-safe database client for Node.js and TypeScript. Prisma Migrate then allows to generate SQL migrations from the Prisma schema and executes them against the database. It uses the Prisma schema to define application models in a declarative way. Prisma is a new kind of ORM that mitigates many problems of traditional ORMs, such as bloated model instances, mixing business with storage logic, lack of type-safety or unpredictable queries caused e.g. Instances of the model classes then provide an interface for CRUD queries to an application at runtime. These model classes can be used to generate SQL migrations. TypeORM is a traditional ORM which maps tables to model classes. While Prisma and TypeORM solve similar problems, they work in very different ways.
