Configuration
Once you have created your scraping browser, you can get started by following this guide.
To get started, you need your API credentials, your Username and Password. You can find these credentials in the Access Parameters tab of newly created Scraping Browser.
Installation
Sample Code
Try running the example script below (swap in your credentials, zone, and target URL):
Run the Script
Save the above code as script.js
and run it using this command:
node script.js
View live browser session
The Scraping Browser Debugger enables developers to inspect, analyze, and fine-tune their code alongside Chrome Dev Tools, resulting in better control, visibility, and efficiency. You can integrate the following code snippet to launch devtools automatically for every session:
// Node.js Puppeteer - launch devtools locally
const { exec } = require('child_process');
const chromeExecutable = 'google-chrome';
const delay = ms => new Promise(resolve => setTimeout(resolve, ms));
const openDevtools = async (page, client) => {
// get current frameId
const frameId = page.mainFrame()._id;
// get URL for devtools from scraping browser
const { url: inspectUrl } = await client.send('Page.inspect', { frameId });
// open devtools URL in local chrome
exec(`"${chromeExecutable}" "${inspectUrl}"`, error => {
if (error)
throw new Error('Unable to open devtools: ' + error);
});
// wait for devtools ui to load
await delay(5000);
};
const page = await browser.newPage();
const client = await page.target().createCDPSession();
await openDevtools(page, client);
await page.goto('http://example.com');
Single Navigation Per Session
Scraping Browser sessions are structured to allow one initial navigation per session. This initial navigation refers to the first instance of loading the target site from which data is to be extracted. Following this, users are free to navigate the site using clicks, scrolls, and other interactive actions within the same session. However, to start a new scraping job, either on the same site or a different one, from the initial navigation stage, it is necessary to begin a new session.
