PrismaType

Generate versatile TypeBox schemas from your Prisma schema, as part of prisma generate.

The output is plain TypeBox, so you validate at runtime with Value.Check and derive compile-time types with Static — from a single source of truth.

Requirements

• Prisma 7 or newer
• Node.js 22 or newer
• TypeBox 1.x or newer (the unscoped typebox package, or a package that re-exports the 1.x API)

Install

npm i -D prismatype
pnpm i -D prismatype
bun add -D prismatype

Add the generator to your schema.prisma:

generator prismatype {
  provider = "prismatype"
  output   = "./prismatype"
  inputModel = true
}

Then generate:

npx prisma generate

PrismaType writes one .ts file per model into a models/ subdirectory of the output directory, plus a shared enums.ts, a model.ts re-export, and the __nullable__ / __transformDate__ helpers at the output root.

⚠️ The output directory is wiped and recreated on every generate. Point output at a folder that PrismaType fully owns — don't keep hand-written files there.
