Packages

prisma/prisma is a pnpm workspace with ~46 published packages plus a few internal ones. This page is the map. Each row links to its dedicated wiki page where one exists; small or thin packages are grouped under Other packages.

The workspace is governed by pnpm-workspace.yaml (packages/* glob) and built by Turborepo.

How packages depend on each other

A regenerable view exists at graphs/dependencies.png (run ts-node scripts/graph-dependencies.ts). At a high level:

• cli depends on most other packages
• client depends on client-engine-runtime, client-common, client-runtime-utils, driver-adapter-utils
• Generators depend on client-common, ts-builders, client-generator-registry
• Adapters depend on driver-adapter-utils
• Almost everything depends on debug, engines, internals, and config

When you change a low-level package, run pnpm build from the repo root so dependents pick up the change in topological order.
