How to Fix the Deprecated 'page.waitForTimeout' Method Usage

If you're encountering a deprecation warning regarding the 'page.waitForTimeout' method in Puppeteer, it means that the method is no longer recommended for use and may be removed in future versions of Puppeteer. To address this issue, you should update your code to use an alternative approach for waiting in Puppeteer.

The 'page.waitForTimeout' method has been deprecated in favor of other methods that provide clearer and more explicit ways of waiting in Puppeteer.

Solution:

To fix this issue, you can replace usages of 'page.waitForTimeout' with either 'setTimeout' or 'page.waitFor' depending on your specific use case.

Using setTimeout:

If you simply want to wait for a specified amount of time, you can use the built-in JavaScript 'setTimeout' function:


    const puppeteer = require('puppeteer');

    (async () => {
      const browser = await puppeteer.launch();
      const page = await browser.newPage();
      
      // Wait for 2000 milliseconds (2 seconds)
      await setTimeout(() => {}, 2000);

      await browser.close();
    })();
  

Using page.waitFor:

If you want to wait for a specific condition to be met, such as an element to appear on the page, you can use 'page.waitFor':


    const puppeteer = require('puppeteer');

    (async () => {
      const browser = await puppeteer.launch();
      const page = await browser.newPage();
      
      // Wait for an element with id 'myElement' to appear on the page
      await page.waitFor('#myElement');

      await browser.close();
    })();
  

By updating your code to use 'setTimeout' or 'page.waitFor' instead of 'page.waitForTimeout', you can resolve the deprecation warning and ensure compatibility with future versions of Puppeteer.
