prisma-gen

Prisma Generator

Designing database schemas means thinking about relations, indexes, and constraints. Describe your data and get a complete Prisma schema.

One command. Zero config. Just works.

Quick Start

npx ai-prisma-gen "e-commerce with users, products, and orders"

What It Does

• Generates complete Prisma schema from descriptions
• Sets up proper relations and constraints
• Includes common fields (createdAt, updatedAt)
• Handles enums and indexes

Usage Examples

# E-commerce schema
npx ai-prisma-gen "e-commerce with users, products, orders"

# SaaS schema
npx ai-prisma-gen "SaaS with organizations, users, and subscriptions"

# Social app
npx ai-prisma-gen "social app with users, posts, likes, and follows"

Best Practices

• Use relations - let Prisma handle joins
• Add indexes - for frequently queried fields
• Consider soft deletes - deletedAt instead of actual delete
• Review and refine - AI gets 80%, you add the rest

When to Use This

• Starting a new database design
• Learning Prisma schema syntax
• Rapid prototyping
• Getting a baseline to customize
