Here's a basic guide on how to set up Playwright automation with TypeScript:

Step 1: Install Node.js and TypeScript

Make sure you have Node.js installed on your machine. You can download it from [Node.js official website](https://nodejs.org/).

Next, install TypeScript globally using the following command:

```bash

npm install -g typescript

```

Step 2: Create a TypeScript Project

Create a new directory for your project and navigate into it:

```bash

mkdir playwright-automation

cd playwright-automation

```

Initialize a new TypeScript project:

```bash

npm init -y

```

Step 3: Install Playwright

Install Playwright as a dependency:

```bash

npm install playwright

```

Step 4: Write TypeScript Code

Create a TypeScript file, e.g., `example.ts`, and open it in your code editor.

```typescript

// example.ts

import { chromium, Browser, Page } from 'playwright';

async function run() {

  const browser: Browser = await chromium.launch();

  const page: Page = await browser.newPage();

  // Navigate to a website

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

  // Perform automation tasks

  await page.fill('input[name="q"]', 'Playwright automation');

  await page.press('input[name="q"]', 'Enter');

  // Wait for the results page to load

  await page.waitForSelector('h3');

  // Extract information

  const titles = await page.$$eval('h3', (elements) => elements.map((el) => el.textContent));

  // Display the results

  console.log('Search results:', titles);

  // Close the browser

  await browser.close();

}

// Run the script

run().catch(console.error);

```

Step 5: Compile and Run

Compile the TypeScript code into JavaScript:

```bash

tsc

```

Now, you should have a `example.js` file generated in your project directory. You can run it using Node.js:

```bash

node example.js

```
