Dual Select & Insert Schemas

Generates full select schemas for database records and input DTO schemas where autoincrement IDs, UUIDs, and creation timestamps are marked optional.

String & Format Validation

Detects length options as .max(), validates emails with .email(), URLs with .url(), and UUIDs with .uuid().

100% Client-Side Privacy

All AST parsing and code synthesis happen locally in your web browser. Sensitive entity classes and schema structures never touch any remote server.

Copy the generated Zod schemas or download as a .ts file.

TypeORM Entity to Zod Schema Conversion

The converter parses the User entity class, generates both userSchema (select) and insertUserSchema (insert DTO) with integer and email constraints, and exports inferred TypeScript type aliases.

TypeORM Entity (TypeScript) Source 
@Entity('users')
export class User {
  @PrimaryGeneratedColumn()
  id: number;

  @Column({ type: 'varchar', length: 255 })
  name: string;

  @Column({ type: 'varchar', length: 255, unique: true })
  email: string;

  @CreateDateColumn()
  createdAt: Date;
}
Zod Schemas (TypeScript) Processed 
import { z } from 'zod';

export const userSchema = z.object({
  id: z.number().int(),
  name: z.string().max(255),
  email: z.string().email(),
  createdAt: z.date(),
});
export type User = z.infer<typeof userSchema>;

export const insertUserSchema = z.object({
  id: z.number().int().optional(),
  name: z.string().max(255),
  email: z.string().email(),
  createdAt: z.date().optional(),
});
export type InsertUser = z.infer<typeof insertUserSchema>;

Frequently Asked Questions

How does this tool handle autoincrement primary keys and timestamps in insert schemas?
In insert schemas, fields decorated with @PrimaryGeneratedColumn(), @CreateDateColumn(), and @UpdateDateColumn() are automatically wrapped with .optional() so you can validate incoming API payloads before the database assigns them.
How are TypeORM relations handled?
Virtual navigation relations (@OneToMany, @ManyToMany) that do not represent direct database table columns are excluded from validation schemas, while scalar foreign key columns annotated with @ManyToOne and @JoinColumn are preserved.
Is my schema data private?
Yes, 100%. The conversion runs entirely inside your browser's JavaScript engine. No code is transmitted to any external server.
