 ```

2. Require Packages: In your script, you need to require both Playwright and the database library.

 ```javascript

 const { chromium } = require('playwright');

 const mysql = require('mysql2'); - Playwright Course in Hyderabad

3. Database Connection Configuration: Configure your database connection parameters. This will depend on the type of database you're using (MySQL, PostgreSQL, SQLite, etc.).

 const dbConfig = {

 host: 'localhost',

 user: 'your_username',

 password: 'your_password',

 database: 'your_database', -

 };

 ```

 ```javascript

 const connection = mysql.createConnection(dbConfig);

 // Connect to the database

 connection.connect((err) => {

 if (err) {

 console.error('Error connecting to database:', err);

 return;

 }

 console.log('Connected to the database');

 });

 ```

 ```javascript

 (async () => {

 const browser = await chromium.launch();

 const context = await browser.newContext();

 const page = await context.newPage();

 // Your Playwright automation code here

 if (err) {
