Drizzle Kit overview and config file docs

drizzle-kit push lets you literally push your schema and subsequent schema changes directly to the database while omitting SQL files generation, it’s designed to cover code first approach of Drizzle migrations.

How it works under the hood?

When you run Drizzle Kit push command it will:

Read through your Drizzle schema file(s) and compose a json snapshot of your schema
Pull(introspect) database schema
Based on differences between those two it will generate SQL migrations
Apply SQL migrations to the database

import * as p from "drizzle-orm/mysql-core";

export const users = p.mysqlTable("users", {
  id: p.int().primaryKey().autoincrement(),
  name: p.varchar({ length: 255 }),
});

   create table `users` (`id` int AUTO_INCREMENT PRIMARY KEY, `name` varchar(255));

It’s the best approach for rapid prototyping and we’ve seen dozens of teams and solo developers successfully using it as a primary migrations flow in their production applications. It pairs exceptionally well with blue/green deployment strategy and serverless databases like Planetscale, Neon, Turso and others.

drizzle-kit push requires you to specify dialect, path to the schema file(s) and either database connection url or user:password@host:port/db params, you can provide them either via drizzle.config.ts config file or via CLI options:

With config file

With CLI options

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

export default defineConfig({
  dialect: "mysql",
  schema: "./src/schema.ts",
  dbCredentials: {
    url: "mysql://user:password@host:3306/dbname",
  },
});

npx drizzle-kit push

npx drizzle-kit push --dialect=mysql --schema=./src/schema.ts --url=mysql://user:password@host:3306/dbname

Schema files path

You can have a single schema.ts file or as many schema files as you want spread out across the project. Drizzle Kit requires you to specify path(s) to them as a glob via schema configuration option.

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 or different databases on the same project:

npm

yarn

pnpm

bun

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

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

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

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

📦 <project root>
 ├ 📂 drizzle
 ├ 📂 src
 ├ 📜 .env
 ├ 📜 drizzle-dev.config.ts
 ├ 📜 drizzle-prod.config.ts
 ├ 📜 package.json
 └ 📜 tsconfig.json

Including tables

drizzle-kit push will manage all MySQL tables by default. You can configure the list of tables via tablesFilter.


`tablesFilter`	`glob` based table names filter, e.g. `["users", "user_info"]` or `"user"`. Default is `""`

Let’s configure drizzle-kit to operate with all tables in the connected MySQL database.

import { defineConfig } from "drizzle-kit";

export default defineConfig({
  dialect: "mysql",
  schema: "./src/schema.ts",
  dbCredentials: {
    url: "mysql://user:password@host:3306/dbname",
  },
  tablesFilter: ["*"],
});

npx drizzle-kit push

Extended list of configurations

drizzle-kit push has a list of cli-only options


`verbose`	print all SQL statements prior to execution
`explain`	print the planned SQL changes, without applying them (dry run)
`force`	auto-accept all data-loss statements

npm

yarn

pnpm

bun

npx drizzle-kit push --explain --verbose --force

yarn drizzle-kit push --explain --verbose --force

pnpm drizzle-kit push --explain --verbose --force

bunx drizzle-kit push --explain --verbose --force

We recommend configuring drizzle-kit through drizzle.config.ts file, yet you can provide all configuration options through CLI if necessary, e.g. in CI/CD pipelines, etc.


`dialect`	`required`	Database dialect, one of `postgresql` `mysql` `sqlite` `turso` `singlestore` `mssql` `cockroach`
`schema`	`required`	Path to typescript schema file(s) or folder(s) with multiple schema files
`tablesFilter`		Table name filter
`url`		Database connection string
`user`		Database user
`password`		Database password
`host`		Host
`port`		Port
`database`		Database name
`config`		Configuration file path, default=`drizzle.config.ts`

npm

yarn

pnpm

bun

npx drizzle-kit push dialect=mysql schema=src/schema.ts url=mysql://user:password@host:3306/dbname
npx drizzle-kit push dialect=mysql schema=src/schema.ts --tablesFilter=‘user*’ url=mysql://user:password@host:3306/dbname

yarn drizzle-kit push dialect=mysql schema=src/schema.ts url=mysql://user:password@host:3306/dbname
yarn drizzle-kit push dialect=mysql schema=src/schema.ts --tablesFilter=‘user*’ url=mysql://user:password@host:3306/dbname

pnpm drizzle-kit push dialect=mysql schema=src/schema.ts url=mysql://user:password@host:3306/dbname
pnpm drizzle-kit push dialect=mysql schema=src/schema.ts --tablesFilter=‘user*’ url=mysql://user:password@host:3306/dbname

bunx drizzle-kit push dialect=mysql schema=src/schema.ts url=mysql://user:password@host:3306/dbname
bunx drizzle-kit push dialect=mysql schema=src/schema.ts --tablesFilter=‘user*’ url=mysql://user:password@host:3306/dbname

Extended example

Let’s declare drizzle schema in the project and push it to the database via drizzle-kit push command

📦 <project root>
 ├ 📂 src
 │ ├ 📜 schema.ts
 │ └ 📜 index.ts
 ├ 📜 drizzle.config.ts
 └ …

drizzle.config.ts

src/schema.ts

import { defineConfig } from "drizzle-kit";

export default defineConfig({
  dialect: "mysql",
  schema: "./src/schema.ts",
  dbCredentials: {
    url: "mysql://user:password@host:3306/dbname"
  },
});

import * as p from "drizzle-orm/mysql-core";

export const users = p.mysqlTable("users", {
  id: p.int().primaryKey().autoincrement(),
  name: p.varchar({ length: 255 }),
})

Now let’s run

npx drizzle-kit push

it will pull existing(empty) schema from the database and generate SQL migration and apply it under the hood

CREATE TABLE `users` (
 `id` int AUTO_INCREMENT PRIMARY KEY,
 `name` varchar(255)
);

DONE ✅
