prisma-json-types-generator

The generator gives Prisma Json, String, String[], Int, and Float fields TypeScript types taken from comments in the schema. It only rewrites the types emitted by prisma generate. Nothing is checked at runtime or by the database.

Workflow

1. Read the relevant Prisma schema and, if it exists, the file that declares the PrismaJson namespace. Read tsconfig.json only when the namespace declarations are not picked up.
2. If the generator is not installed or its setup looks broken, read references/setup.md before editing fields.
3. Choose a namespace type or an inline type for the field.
4. Add or fix the /// comment directly above the field.
5. For a namespace type, add or update its declaration.
6. Run prisma generate (prisma generate --sql when the project uses TypedSQL) and the project's type check when you can.

Change only the fields the user asked about.

Namespace or inline types

/// [TypeName] references TypeName in the configured namespace, PrismaJson by default. Use it for objects, types shared by several fields, and anything that may get a Zod schema later.
