Web Scraping with Node.js and Playwright to easily extract information from Amazon

Let's see how to do some Web Scrapping from Amazon for a simple project.

Prerequisites

1. Create a directory, you can call it "scraping":

mkdir scrapping
cd scrapping

2. Initialize your proyect with npm:

npm init -y

3. Install the dependencies:

npm install playwright

4. (Optional) — You might need to install a few more dependencies (Playwright's browser), I use Ubuntu, these were the steps:

sudo npx playwright install-deps
sudo apt-get install libevent-2.1–7

5. Create the Web Scraper code — we will use the following Node script that you can adapt. Create a file named index.mjs with the following content:

import { chromium } from 'playwright';

const browser = await chromium.launch(
    { headless : true }
);

const page = await browser.newPage();

await page.goto(
    'https://www.amazon.com.mx/s?k=thomas+pynchon&__mk_es_MX=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=23H57HYI5SCAL&sprefix=thomas+pynchon%2Caps%2C143&ref=nb_sb_noss_1'
);

const products = await page.$$eval(
    '.s-card-container',
    (results) => (
        results.map((el) => {
            const title = el.querySelector('h2')?.innerText;

            if (!title) {
                return null;
            }

            const image =…
