⚡ zapit

Zap a Zod schema into a fully typed NestJS CRUD API with DynamoDB and CDK.

One command. Full API. No boilerplate.

npx zapit generate ./schemas/user.schema.ts

What it generates

From a single Zod schema file, zapit creates:

• ✅ DTOs — Create, Update, and Response types
• ✅ Controller — Full CRUD endpoints with Zod validation pipe
• ✅ Service — Business logic layer with error handling
• ✅ Repository — DynamoDB or Prisma integration
• ✅ Module — NestJS module wiring everything together
• ✅ Validation Pipe — Zod-powered request validation

Quick Start

1. Scaffold a new project

npx zapit init --name my-api
cd my-api
npm install

2. Define your schema

// schemas/user.schema.ts
import { z } from 'zod';

export const UserSchema = z.object({
  id: z.string().uuid(),
  email: z.string().email(),
  name: z.string().min(1),
  role: z.enum(['admin', 'user', 'moderator']),
  bio: z.string().optional(),
  isActive: z.boolean(),
});

3. Generate

npx zapit generate schemas/user.schema.ts

4. Done

src/
  user/
    dto/user.dto.ts
    user.controller.ts
    user.service.ts
    user.repository.ts
    user.module.ts
    validation.pipe.ts

Import the module into your app and you have a working API.

Commands

zapit init

Scaffold a new NestJS + Fastify + CDK project:

zapit init --name my-api

Generates: package.json, tsconfig.json, src/main.ts, src/app.module.ts, and a cdk/ folder with Lambda + API Gateway + DynamoDB stack.

zapit generate <schema>

Generate a CRUD module from a Zod schema:

zapit generate <schema> [options]

Options:
  -o, --output <dir>   Output directory (default: ./src)
  -d, --dry-run        Preview files without writing
  --no-dynamodb        Skip DynamoDB repository
  --no-cdk             Skip CDK stack generation
  --prisma             Generate Prisma repository instead (Pro ⚡)

Zod Validation Pipe

Every generated controller includes a ZodValidationPipe that validates request bodies against your original Zod schema at runtime. Bad requests get clean error responses automatically.

Prisma Support (Pro ⚡)

Use --prisma to generate Prisma-based repositories instead of DynamoDB:

ZAPIT_LICENSE_KEY=your-key zapit generate schema.ts --prisma

This generates:

• A Prisma-based repository using PrismaClient
• A Prisma schema model definition
