Drizzle pgTable to TypeORM Entity Conversion

The converter detects the pgTable declaration, transforms the table name to PascalCase 'User', annotates the class with @Entity('users'), maps serial primary keys to @PrimaryGeneratedColumn(), varchar strings to @Column(), and timestamp defaultNow() to @CreateDateColumn().

Drizzle Schema (TypeScript) Source 
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()
});
TypeORM Entity (TypeScript) Processed 
@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;
}
