6// TypeScript automatically knows the type!
7app.post('/users')
8  .validate({ body: UserSchema })
9  .handler((req) => {
10    const body = req.body;

1// Success response

4// Error response
5return { success: false, error: 'User not found' };

7// Frontend can use discriminated unions
8if (result.success) {
9  // TypeScript knows result.data exists
10} else {
11  // TypeScript knows result.error exists
12}

1# Scaffold a new project (Zod is included by default)
2npx @morojs/cli init my-api
3cd my-api

5# Replace src/index.ts with the example above, then:
6npm run dev
