drizzle-kit check command lets you check consistency of your generated SQL migrations history.

That’s extremely useful when you have multiple developers working on the project and altering database schema on different branches - read more about migrations for teams.

drizzle-kit check command requires you to specify dialect param, you can provide it either via drizzle.config.ts config file or via CLI options

With config file

As CLI options

// drizzle.config.ts
import { defineConfig } from "drizzle-kit";

export default defineConfig({
  dialect: "mysql",
});

npx drizzle-kit check

npx drizzle-kit check --dialect=mysql

Multiple configuration files in one project

You can have multiple config files in the project, it’s very useful when you have multiple database stages or multiple databases on the same project:

npm

yarn

pnpm

bun

npx drizzle-kit check --config=drizzle-dev.config.ts
npx drizzle-kit check --config=drizzle-prod.config.ts

yarn drizzle-kit check --config=drizzle-dev.config.ts
yarn drizzle-kit check --config=drizzle-prod.config.ts

pnpm drizzle-kit check --config=drizzle-dev.config.ts
pnpm drizzle-kit check --config=drizzle-prod.config.ts

bunx drizzle-kit check --config=drizzle-dev.config.ts
bunx drizzle-kit check --config=drizzle-prod.config.ts

📦 <project root>
 ├ 📂 drizzle
 ├ 📂 src
 ├ 📜 .env
 ├ 📜 drizzle-dev.config.ts
