The Puppeteer equivalent ofwindow.location.reload()
ispage.reload()
. Here's a detailed explanation:
1. Launching a new browser instance and creating a new page:
1 2 3 4 5 6 7 8 9 10 11 12 13
const puppeteer = require('puppeteer'); (async () => { const browser = await puppeteer.launch(); const page = await browser.newPage(); // Perform actions with the page here // Close the browser await browser.close(); })();
This code sets up a basic Puppeteer script. It launches a new headless browser instance and creates a new page to work with.
2. Reloading the page usingpage.reload()
:
To reload the page in Puppeteer, you can use thepage.reload()
method. It reloads the current page, similar to callingwindow.location.reload()
in a browser.
1 2 3
await page.reload();
In this example,page.reload()
is called to reload the current page. The method returns a promise that resolves once the page has finished reloading.
3. Controlling the behavior ofpage.reload()
:
Thepage.reload()
method can accept an optionaloptions
object to control the reload behavior. Some commonly used options include:
1 2 3
await page.reload({ waitUntil: 'networkidle0' });
-waitUntil
: Specifies when the reload should be considered complete. Possible values are'load'
,'domcontentloaded'
, and'networkidle0'
.'networkidle0'
waits until there are no more than 0 network connections for at least 500 ms.
You can refer to the Puppeteer documentation for a complete list of available options for thepage.reload()
method.
By following these steps, you can reload a page in Puppeteer. By calling thepage.reload()
method, you can trigger a page reload similar towindow.location.reload()
in a browser. Additionally, you can control the behavior of the reload by passing an options object with desired settings. This functionality allows you to automate page reloading as part of your Puppeteer scripts for various testing or scraping scenarios.
