How can I extract data from a paginated table using Puppeteer?

The Puppeteer API method to retrieve the response body of a network request isresponse.text() orresponse.buffer(). Here's a detailed explanation:
1. Launching a new browser instance and creating a new page:

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. Retrieving the response body usingresponse.text() orresponse.buffer():
To retrieve the response body of a network request, you can use either theresponse.text() orresponse.buffer() method, depending on the type of data you expect.
- Usingresponse.text():
This code sets up an event listener usingpage.on('response') to capture network responses. When a response is received, theresponse.text() method is called to retrieve the response body as text. The response body is then logged to the console.
- Usingresponse.buffer():
This code is similar to the previous example, but it usesresponse.buffer() instead ofresponse.text() to retrieve the response body as a buffer. The buffer is then converted to a string usingtoString() before logging it to the console.
By utilizing eitherresponse.text() orresponse.buffer(), you can retrieve the response body of a network request in Puppeteer. These methods allow you to access and process the raw data of the response, whether it's text-based or binary, such as HTML, JSON, images, or other file types.
