Get Started with Drizzle and Turso Database

<Prerequisites> - **dotenv** - package for managing environment variables - [read here](https://www.npmjs.com/package/dotenv) - **tsx** - package for running TypeScript files - [read here](https://tsx.is/) - Turso Database - [website](https://docs.turso.tech/introduction) - Turso Database driver - [website](https://docs.turso.tech/connect/javascript) & [GitHub](https://github.com/tursodatabase/turso/tree/main/bindings/javascript) </Prerequisites> <FileStructure/>

Step 1 - Install required package

<Npm> drizzle-orm@beta @tursodatabase/database dotenv -D drizzle-kit@beta tsx </Npm>

Step 2 - Setup connection variables

<SetupEnv env_variable='DB_FILE_NAME' /> <Callout type='info' title='important'> For example, if you want to create an SQLite database file in the root of your project for testing purposes, you can use this example: ```plaintext copy DB_FILE_NAME=mydb.sqlite ``` </Callout>

Step 3 - Connect Drizzle ORM to the database

Step 4 - Create a table

Step 5 - Setup Drizzle config file

Step 6 - Applying changes to the database

Step 7 - Seed and Query the database

typescript

import 'dotenv/config';
import { eq } from 'drizzle-orm';
import { drizzle } from 'drizzle-orm/tursodatabase/database';
import { usersTable } from './db/schema';

async function main() {
  const db = drizzle();

  const user: typeof usersTable.$inferInsert = {
    name: 'John',
    age: 30,
    email: '[email protected]',
  };

  await db.insert(usersTable).values(user);
  console.log('New user created!')

  const users = await db.select().from(usersTable);
  console.log('Getting all users from the database: ', users)
  /*
  const users: {
    id: number;
    name: string;
    age: number;
    email: string;
  }[]
  */

  await db
    .update(usersTable)
    .set({
      age: 31,
    })
    .where(eq(usersTable.email, user.email));
  console.log('User info updated!')

  await db.delete(usersTable).where(eq(usersTable.email, user.email));
  console.log('User deleted!')
}

main();

Step 8 - Run index.ts file
