Web Scraping Dynamic JS Websites Made Easy with Playwright and Groq AI

Introduction

Web scraping has become an essential skill in today's data-driven world. With the rise of dynamic JavaScript websites, scraping them can be a daunting task. In this article, we'll explore how to make web scraping dynamic JS websites easy using Playwright and Groq AI.

What is Playwright?

Playwright is a Node library that automates browsers. It supports webkit, chromium, and firefox. With Playwright, you can automate browser interactions, take screenshots, and even record video.

What is Groq AI?

Groq AI is a powerful AI-powered parser that can extract data from web pages. It's easy to use and can handle complex HTML structures.

Setting up the Environment

To get started, you'll need to install the following packages:

npm install playwright groq
Enter fullscreen mode Exit fullscreen mode

Playwright Basics

Here's a basic example of how to use Playwright to automate a browser:

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

(async () => {
  const browser = await chromium.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.screenshot({path: 'screenshot.png'});
  await browser.close();
})();
Enter fullscreen mode Exit fullscreen mode

Scraping Dynamic JS Websites with Playwright

To scrape dynamic JS websites, we'll use Playwright to automate the browser and Groq AI to extract the data. Here's an example:

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

(async () => {
  const browser = await chromium.launch();
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await page.click('text=Load more');
  const html = await page.content();
  const data = groq(html);
  console.log(data);
  await browser.close();
})();
Enter fullscreen mode Exit fullscreen mode

Groq AI Configuration

To use Groq AI, you'll need to configure it. Here's an example:

const groq = require('groq');

const config = {
  selector: '.item',
  attributes: ['title', 'description', 'price'],
  filters: {
    price: (value) => value > 100
  }
};

const data = groq(html, config);
console.log(data);
Enter fullscreen mode Exit fullscreen mode
