prisma

Prisma is a modern open-source toolkit for data access in application development, most commonly referred to in the context of Prisma ORM for Node.js and TypeScript. It provides a type-safe interface for querying and mutating database data, aiming to improve developer productivity and reliability by generating a tailored API from a declarative data model.

The core components of the Prisma toolkit include the Prisma schema, Prisma Client, Prisma Migrate, and Prisma Studio. The Prisma schema defines models, relations, and database configuration in one place, and from this schema Prisma Client is generated as a type-safe query API. Prisma Migrate handles schema migrations, enabling evolution of the database schema alongside application code. Prisma Studio offers a graphical user interface to view and edit data stored in the database, helping developers manage content during development and debugging.

Prisma is designed to work with relational databases such as PostgreSQL, MySQL, and SQLite, and it emphasizes type safety, auto-completion, and predictable query behavior. It integrates with common web frameworks in the Node.js ecosystem and is used to streamline data access patterns, including handling relations, nested writes, and transactions, while reducing boilerplate SQL.

In the broader context, the term prisma can also refer to the general concept of a prism in optics or to translations of the word into various languages. In software discussions, however, Prisma most often denotes the database toolkit and its associated tools.
