aria-expanded="false" data-state="closed">Drizzle is an ORM that supports both a SQL-like “query builder” API and an ORM-like Queries API. It supports the bun:sqlite built-in module. Let’s get started by creating a fresh project with bun init and installing Drizzle. terminalCopybun init -y bun add drizzle-orm bun add -D drizzle-kit Then we’ll connect to a SQLite database using the bun:sqlite module and create the Drizzle database instance. db.tsCopyimport { drizzle } from "drizzle-orm/bun-sqlite"; import { Database } from "bun:sqlite"; const sqlite = new Database("sqlite.db"); export const db = drizzle(sqlite); To see the database in action, add these lines to index.ts. index.tsCopyimport { db } from "./db"; import { sql } from "drizzle-orm"; const query = sql`select "hello world" as text`; const result = db.gettext: string }>(query); console.log(result); Then run index.ts with Bun. Bun will automatically create sqlite.db and execute the query. terminalCopybun run index.ts Copy{ text: "hello world" } Lets give our database a proper schema. Create a schema.ts file and define a movies table. schema.tsCopyimport { sqliteTable, text, integer } from "drizzle-orm/sqlite-core"; export const movies = sqliteTable("movies", { id: integer("id").primaryKey(), title: text("name"), releaseYear: integer("release_year"), }); We can use the drizzle-kit CLI to generate an initial SQL migration. terminalCopybunx drizzle-kit generate --dialect sqlite --schema ./schema.ts This creates a new drizzle directory containing a .sql migration file and meta directory. File TreeCopydrizzle ├── 0000_ordinary_beyonder.sql └── meta ├── 0000_snapshot.json └── _journal.json We can execute these migrations with a simple migrate.ts script. This script creates a new connection to a SQLite database that writes to sqlite.db, then executes all unexecuted migrations in the drizzle directory. migrate.tsCopyimport { migrate } from "drizzle-orm/bun-sqlite/migrator"; import { drizzle } from "drizzle-orm/bun-sqlite"; import { Database } from "bun:sqlite"; const sqlite = new Database("sqlite.db"); const db = drizzle(sqlite); migrate(db, { migrationsFolder: "./drizzle" }); We can run this script with bun to execute the migration. terminalCopybun run migrate.ts Now that we have a database, let’s add some data to it. Create a seed.ts file with the following contents. seed.tsCopyimport { db } from "./db"; import * as schema from "./schema"; await db.insert(schema.movies).values([ { title: "The Matrix", releaseYear: 1999, }, { title: "The Matrix Reloaded", releaseYear: 2003, }, { title: "The Matrix Revolutions", releaseYear: 2003, }, ]); console.log(`Seeding complete.`); Then run this file. terminalCopybun run seed.ts CopySeeding complete. We finally have a database with a schema and some sample data. Let’s use Drizzle to query it. Replace the contents of index.ts with the following. index.tsCopyimport * as schema from "./schema"; import { db } from "./db"; const result = await db.select().from(schema.movies); console.log(result); Then run the file. You should see the three movies we inserted. terminalCopybun run index.ts Copy[ { id: 1, title: "The Matrix", releaseYear: 1999 }, { id: 2, title: "The Matrix Reloaded", releaseYear: 2003 }, { id: 3, title: "The Matrix Revolutions", releaseYear: 2003 } ] Refer to the Drizzle website for complete documentation.
