TypeORM Entity to Drizzle pgTable Conversion

The converter parses the User entity class and @Entity('users') decorator, maps @PrimaryGeneratedColumn() to serial('id').primaryKey(), varchar columns to varchar('name', { length: 255 }).notNull(), and @CreateDateColumn() to timestamp('created_at').defaultNow().notNull().

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;
}
Drizzle Schema (TypeScript) Processed
export const users = pgTable('users', {
  id: serial('id').primaryKey(),
  name: varchar('name', { length: 255 }).notNull(),
  email: varchar('email', { length: 255 }).notNull().unique(),
  createdAt: timestamp('created_at').defaultNow().notNull()
});

Frequently Asked Questions

How does this tool map TypeORM column decorators to Drizzle?
TypeORM decorators like @PrimaryGeneratedColumn, @Column, @CreateDateColumn, and @UpdateDateColumn are mapped to Drizzle table column builders such as serial, integer, varchar, text, boolean, timestamp, jsonb, and uuid with matching constraints.
Does it support Drizzle relations?
Yes. Foreign key columns annotated with @ManyToOne and @JoinColumn are mapped to .references(() => otherTable.id) and companion relations() blocks.
Is my schema data private?
Yes, 100%. The conversion runs entirely inside your browser sandbox. No source code or schema models are sent across the network.
