Playwright Automation: Managing Database Connectivity

To connect to a database using Playwright, you would typically not use Playwright itself for database connectivity. Playwright is primarily a tool for browser automation, allowing you to interact with web pages & web applications.

Here's a general outline of how you might connect to a database using Playwright in a JavaScript/Node.js environment:

1. Install the necessary database library: Depending on the type of database you're using, you'll need to install a corresponding Node.js library.

For example, if you're using PostgreSQL, you might install `pg`:

   ```bash

   npm install pg

   ```

2. Require/import the database library: In your Node.js script where you're using Playwright, you would also import the database library you installed.

3. Connect to the database: You'll typically need to provide connection details such as host, port, username, password, and database name to connect to your database. - Playwright Automation Online Training

Here's a simple example for PostgreSQL:

   ```javascript

   const { Client } = require('pg');

   const client = new Client({

       user: 'username',

       host: 'localhost',

       database: 'mydatabase',

       password: 'password',

       port: 5432, // Default PostgreSQL port

   });

   async function connect() {

       try {

           await client.connect();

           console.log('Connected to database');

       } catch (error) {

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

       }

   }

   connect();

   ```

4. Perform database operations: Once connected, you can execute SQL queries, insert/update data, etc., as needed within your Playwright scripts. - Playwright Automation Testing Hyderabad

Here's a very basic example of how you might combine Playwright with database connectivity to interact with a web application and store some data in a PostgreSQL database:

```javascript

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

const { Client } = require('pg');

const client = new Client({

    user: 'username',

    host: 'localhost',

    database: 'mydatabase',

    password: 'password',

    port: 5432, // Default PostgreSQL port

});

async function main() {

    const browser = await chromium.launch();

    const page = await browser.newPage();

    await page.goto('https://example.com');

    // Interact with the web page using Playwright

    // Example: extract data from the page

    const title = await page.title();

    console.log('Page title:', title);

    // Connect to the database

    try {

        await client.connect();

        console.log('Connected to database');

        // Insert data into a table

        await client.query('INSERT INTO mytable (column1, column2) VALUES ($1, $2)', ['value1', 'value2']);

        console.log('Data inserted into database');

    } catch (error) {

        console.error('Error connecting to database or inserting data:', error);

    } finally {

        // Close the database connection

        await client.end();

        console.log ('Database connection closed');

    }

    await browser.close();

}

main();

```

Remember to replace `'username'`, `'password'`, `'mydatabase'`, etc., with your actual database credentials and database name. Additionally, adjust the SQL query to match your database schema. - Playwright Online Training
