Drizzle to Kysely Conversion example

Demonstrates converting a PostgreSQL pgTable Drizzle schema into a type-safe Kysely UserTable interface with Generated wrappers.

Drizzle ORM Schema Source 
export const users = pgTable('users', {
  id: serial('id').primaryKey(),
  email: text('email').notNull(),
  name: text('name'),
  createdAt: timestamp('created_at').defaultNow().notNull(),
});
Kysely TypeScript Interfaces Processed 
import type { Generated } from 'kysely';

export interface UserTable {
  id: Generated<number>;
  email: string;
  name: string | null;
  createdAt: Generated<Date>;
}

export interface Database {
  users: UserTable;
}

Yes. All parsing and code generation executes 100% locally in your browser memory. No code is transmitted to any server or external service.
How does the generator handle nullable columns in Drizzle?
Columns in Drizzle without the .notNull() constraint are mapped to T | null in the resulting Kysely interface, reflecting SQL column nullability.
Does this generator require Node.js or any external npm package at runtime?
No. The generator runs completely client-side in vanilla JavaScript with zero external runtime dependencies.
