Prisma overview

Prisma ORM is a next-generation, type-safe Node.js and TypeScript ORM. This monorepo contains the TypeScript source for the Prisma CLI, Prisma Client, Prisma Migrate, driver adapters, and the supporting packages that make up Prisma 7.

What this repository contains

This repository (prisma/prisma) is the TypeScript half of Prisma. It does not contain the Rust engines — those live in prisma/prisma-engines and are pulled in here as compiled binaries (Schema Engine) or WebAssembly modules (PSL parser, query compiler).

The repo ships ~46 npm packages organized as a pnpm workspace:

• The prisma CLI (packages/cli)
• @prisma/client runtime (packages/client)
• @prisma/migrate and the migrate/db subcommands (packages/migrate)
• The two Prisma Client generators: prisma-client (new) in packages/client-generator-ts and the legacy prisma-client-js in packages/client-generator-js
• The new Wasm-based execution stack: packages/client-engine-runtime
• Driver adapters for nine database drivers (packages/adapter-*)
• Glue packages (@prisma/internals, @prisma/config, @prisma/engines, @prisma/debug, etc.)

See Architecture for the high-level component map.

Audience

This wiki is written for engineers contributing to prisma/prisma itself. End-user documentation lives at prisma.io/docs. When user-facing behavior is described here, it is from the implementer's perspective — for example, "prisma generate is dispatched by packages/cli/src/Generate.ts" rather than "how to run prisma generate".
