![]() We'll need to follow these steps to make it work: To be able to fetch all quotes, we will need the document.querySelectorAll function instead. Previously we used document.getQuerySelector to select the first matching element (the first quote). Now that we know how to fetch one quote, let's trick our code a bit to get all the quotes and extract their data one by one. Now, let's expand it and fetch all the current page quotes. We did it! Our first scraped element is here, right in the terminal. Output of our script after running node index.js npm init -y Initialize the package.json file using the npm init commandĪfter typing this command, you should find this package.json file in your repository tree. It's helpful to add information to the repository and NPM packages, such as the Puppeteer library. Now, it's time to initialize your Node.js repository with a package.json file. ![]() mkdir first-puppeteer-scraper-example Create a new project folder using mkdir ![]() It'll contain the code of our future scraper. New project.new folder! First, create the first-puppeteer-scraper-example folder on your computer. Let's dive in! □ How to Initialize Your First Puppeteer Scraper It'll improve your learning and understanding of the topic. Prerequisitesīefore diving in and scraping our first page together using JavaScript, Node.js, and the HTML DOM, I'd recommend having a basic understanding of these technologies. I structured the writing to show you some basics of fetching information on a website and clicking a button (for example, moving to the next page).Īt the end of this introduction, I'll recommend ways to practice and learn more by improving the project we just created. I'll introduce the basics of web scraping in JavaScript and Node.js using Puppeteer in this article. For simple data extraction, you can use Axios to fetch an API responses or a website HTML.īut if you're looking to do more advanced tasks including automations, you'll need libraries such as Puppeteer, Cheerio, or Nightmare (don't worry the name is nightmare, but it's not that bad to use □). JavaScript and Node.js offers various libraries that make web scraping easier. Always make sure you're scraping sites that allow it, and performing this activity within ethical and legal limits. Disclaimer: Be careful when doing web scraping. Using scripts, we can extract the data we need from a website for various purposes, such as creating databases, doing some analytics, and even more. Welcome to the world of web scraping! Have you ever needed data from a website but found it hard to access it in a structured format? This is where web scraping comes in.
