GraphQL Schema to Drizzle ORM Generator
Transform GraphQL SDL schemas into type-safe Drizzle ORM tables and relations with inverted nullability for PostgreSQL, MySQL, and SQLite.
At a glance
GraphQL Schema to Drizzle ORM Generator is a free developer utility that transforms GraphQL SDL type definitions into type-safe TypeScript Drizzle ORM schemas. It handles inverted nullability (! to .notNull()), generates foreign keys and relations() helpers, and outputs pgTable, mysqlTable, or sqliteTable definitions 100% client-side in browser memory.
100% Client-Side GraphQL to Drizzle ORM Schema Generator
Zero Server UploadsTransform GraphQL SDL schemas into type-safe Drizzle ORM TypeScript tables, relations() helpers, and inferred types with inverted nullability.
// Click "Generate Drizzle Schema" or pick a Preset above.Inverted Nullability Semantics
GraphQL SDL considers fields nullable unless marked with an exclamation point (!). The generator accurately translates String! to .notNull() and preserves optionality for unadorned fields.
Type-Safe relations() Helper
Object references synthesize both foreign key columns (authorId: integer().references()) and Drizzle one() / many() relational bindings for effortless relational querying.
Inferred Select & Insert Types
Automatically exports TypeScript helper types using typeof users.$inferSelect and typeof users.$inferInsert for zero-boilerplate type safety across full-stack applications.

GraphQL SDL to Drizzle ORM Schema example
Demonstrates table definition generation with inverted nullability (.notNull() on name and title, bio nullable) and foreign key relation synthesis from author: User! to authorId with references().
type User {
id: ID!
name: String!
bio: String
posts: [Post!]!
}
type Post {
id: ID!
title: String!
author: User!
}
export const users = pgTable('users', {
id: serial('id').primaryKey(),
name: varchar('name', { length: 255 }).notNull(),
bio: text('bio'),
});
export const posts = pgTable('posts', {
id: serial('id').primaryKey(),
title: varchar('title', { length: 255 }).notNull(),
authorId: integer('author_id').references(() => users.id).notNull(),
});
