drizzle-typebox is a plugin for Drizzle ORM that allows you to generate Typebox schemas from Drizzle ORM schemas.

Install the dependencies

npm i drizzle-typebox


import { pgEnum, pgTable, serial, text, timestamp } from 'drizzle-orm/pg-core';
import { createInsertSchema, createSelectSchema } from 'drizzle-typebox';
import { Type } from '@sinclair/typebox';
import { Value } from '@sinclair/typebox/value';

const users = pgTable('users', {
    id: serial('id').primaryKey(),
    name: text('name').notNull(),
    email: text('email').notNull(),
    role: text('role', { enum: ['admin', 'user'] }).notNull(),
    createdAt: timestamp('created_at').notNull().defaultNow(),

// Schema for inserting a user - can be used to validate API requests
const insertUserSchema = createInsertSchema(users);

// Schema for selecting a user - can be used to validate API responses
const selectUserSchema = createSelectSchema(users);

// Overriding the fields
const insertUserSchema = createInsertSchema(users, {
    role: Type.String(),

// Refining the fields - useful if you want to change the fields before they become nullable/optional in the final schema
const insertUserSchema = createInsertSchema(users, {
    id: (schema) => Type.Number({ minimum: 0 }),
    role: Type.String(),

// Usage

const isUserValid: boolean = Value.Check(insertUserSchema, {
    name: 'John Doe',
    email: '[email protected]',
    role: 'admin',
