Playwright Connection Closed

When working with Playwright, a headless browser automation library, the connection to the browser instance can occasionally be closed. Here are a few possible reasons for a closed connection and how to handle it:

  1. Browser crash: If the underlying browser crashes, the connection to the browser will be closed. In this case, you can handle it by restarting the browser and reestablishing the connection. Here’s an example:

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

(async () => {
  const browser = await chromium.launch();
  const context = await browser.newContext();
  const page = await context.newPage();
  
  // Do your automated tasks
  
  // Check if connection is still open
  if (context.isConnected()) {
    console.log('Browser connection is still open');
  } else {
    console.log('Browser connection closed. Restarting browser...');
    await browser.close();
    
    // Restart the browser and reconnect
    const newBrowser = await chromium.launch();
    const newContext = await newBrowser.newContext();
    
    // Continue your automation with the new connection
    // ...
  }
  
  // Close the browser when done
  await browser.close();
})();
  2. Timeout: If there is a long period of inactivity, the connection may be closed due to a timeout. To prevent this, you can set a custom timeout for your actions. Here’s an example:

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

(async () => {
  const browser = await chromium.launch();
  const context = await browser.newContext();
  const page = await context.newPage();
  
  // Set a custom timeout for actions (e.g., 10 seconds)
  page.setDefaultTimeout(10000);
  
  // Do your automated tasks
  
  // Close the browser when done
  await browser.close();
})();
  3. Graceful closure: Sometimes, you may want to gracefully close the browser connection. You can use the browser.close() method to close the connection explicitly. Here’s an example:

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

(async () => {
  const browser = await chromium.launch();
  const context = await browser.newContext();
  const page = await context.newPage();
  
  // Do your automated tasks
  
  // Close the browser gracefully
  await browser.close();
})();

    It’s important to note that Playwright will automatically close the browser connection when the Node.js process exits. However, it’s good practice to explicitly close the connection using browser.close() to free up system resources.
