PrismaGen

Generate API route handlers and Prisma function wrappers from prisma/schema.prisma.

• Generates Next.js-style route handlers under app/api/<model>/route.ts
• Generates thin Prisma wrappers under prisma/functions/<Model>/<Model>Fun.ts
• Optional interactive TUI (--interactive) to select models, includes, and protected methods

Requirements

• Node.js >=18
• A project with prisma/schema.prisma
• prisma and react installed in the target project (can be in dependencies or devDependencies; the CLI checks this)

Run via npx / bunx

After you publish this package:

npx @arian8ultra/prismagen --interactive
# or
bunx @arian8ultra/prismagen --interactive

Non-interactive (uses prisma/api-gen.config.json or defaults):

npx @arian8ultra/prismagen

Local development (this repo)

npm install
npm run build
node dist/cli.js --interactive

Configuration

PrismaGen reads (and in --interactive mode writes) configuration at:

• prisma/api-gen.config.json

Key options:

• apiRoot: output folder for API routes (default: app/api)
• functionsRoot: output folder for Prisma wrappers (default: prisma/functions)
• prismaClientImport: import path used in generated files (example: @/prisma/prisma)
• prismaImportStyle: "named" or "default"
• authImport: import path for your auth helpers (example: @/auth/AuthFunctions)
• authGuardFn: function called to enforce auth (example: IsAuthenticatedAdmin)
• protectMethods: list of HTTP methods requiring auth (example: ["POST","PUT","DELETE"])
• fieldDenylist: fields excluded from create/update payload picking
• generateApisForModels: if present, only generate API routes for these models
• generateFunctionsForModels: if present, only generate wrappers for these models
• includes: per-model list of relations included for <Model>_GetById

Notes

• Run the CLI from your project root (the folder that contains prisma/schema.prisma).
• The generator uses @prisma/internals to read Prisma DMMF from your schema.
