Playwright

Playwright is a powerful open-source library for automating web browsers. It allows you to write browser automation scripts in various programming languages, such as JavaScript, Python, and C#. Playwright provides a consistent and reliable API for interacting with browsers, including Chrome, Firefox, and WebKit.

With Playwright, you can automate tasks like filling out forms, clicking buttons, navigating through pages, taking screenshots, scraping data, and running end-to-end tests on web applications. It offers cross-browser support, meaning you can write scripts that work seamlessly across different browsers.

Here's a basic example of using Playwright in JavaScript to open a web page, fill in a form, and submit it:

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

(async () => {
  // Launch a new browser instance
  const browser = await chromium.launch();

  // Create a new browser context
  const context = await browser.newContext();

  // Create a new page
  const page = await context.newPage();

  // Navigate to a website
  await page.goto('https://example.com');

  // Fill in a form field
  await page.fill('input[name="username"]', 'myusername');

  // Click a button to submit the form
  await page.click('button[type="submit"]');

  // Wait for navigation to complete
  await page.waitForNavigation();

  // Take a screenshot
  await page.screenshot({ path: 'example.png' });

  // Close the browser
  await browser.close();
})();
