Setting Up Node.js

Setting up Node.js is the first step towards utilizing the power of Bright Data for web scraping. Node.js is a popular JavaScript runtime environment that allows developers to execute JavaScript code outside of a web browser. It provides a vast ecosystem of libraries and tools, making it an ideal choice for building scalable and efficient web scraping applications.

Assuming you have Node.js installed, create a new project directory and run the following commands:

npm init -y 

This will set up your package.json file, where your dependencies will live.

Next, we’ll want to run the following command to install the Bright Data SDK for Node.js:

npm install @brightdata/sdk

This command will download and install the Bright Data SDK from the npm registry.

Setting up Bright Data and Puppeteer

To begin using Bright Data in your Node.js project, you need to initialize the Bright Data SDK and configure it with your Bright Data account details. Follow these steps:

In your the root project, open the entry point file (e.g., “index.js”) in a code editor and import the Bright Data SDK by adding the following line at the top of your file:

const BrightData = require('@brightdata/sdk');

Initialize the Bright Data SDK with your account details. Add the following code snippet:

const brightDataClient = new BrightData.Client('YOUR_API_KEY');

Replace ‘YOUR_API_KEY’ with your actual Bright Data API key, which can be obtained from your Bright Data account dashboard.

With the Bright Data SDK initialized, you can now leverage its capabilities for web scraping. Use the SDK’s functions and methods to configure proxies, handle sessions, and perform web requests through Bright Data’s proxy network.

For example, to make a web request using Bright Data, you can use the following code snippet:

const response = await brightDataClient.request('https://www.example.com');

This code sends a GET request to the specified URL using Bright Data’s proxy network. The response object contains the response body, which you can process and extract the desired data.

To handle dynamic content and interact with web pages, you can leverage Puppeteer in combination with Bright Data. Here’s an example of using Puppeteer with Bright Data for web scraping:

const puppeteer = require('puppeteer');
const BrightData = require('@brightdata/sdk');

(async () => {
  // Initialize Bright Data SDK with your API key
  const brightDataClient = new BrightData.Client('YOUR_API_KEY');

  const browser = await puppeteer.launch({
    args: [`--proxy-server=${brightDataClient.getProxyUrl()}`]

  const page = await browser.newPage();

  // Set Bright Data session using the Bright Data SDK
  await page.authenticate({
    username: brightDataClient.getProxyUsername(),
    password: brightDataClient.getProxyPassword()

  await page.goto('https://www.example.com/products');

  // Wait for the product list to load
  await page.waitForSelector('.product');

  // Extract product names and prices
  const productList = await page.$$('.product');
  const products = [];

  for (const product of productList) {
    const name = await product.$eval('.product-name', (element) => element.textContent);
    const price = await product.$eval('.product-price', (element) => element.textContent);

    products.push({ name, price });


  await browser.close();

First, we initialize the Bright Data SDK with your API key. We launch a Puppeteer browser instance and configure it to use Bright Data’s proxy by passing the proxy server URL obtained from the Bright Data SDK. We authenticate the page using Bright Data’s proxy credentials retrieved from the SDK. Then, we navigate to the target URL where the product list is located.

We use page.waitForSelector() to wait for the product list to load on the page. Once the products are loaded, we use page.$$() to fetch all elements matching the .product selector. Then, we loop through each product element and use element.$eval() to extract the name and price by selecting the respective elements within the product element.

We store the extracted data in the products array and finally log it to the console.

Remember to replace 'YOUR_API_KEY' with your Bright Data API key. Additionally, adjust the selectors and scraping logic according to the structure and markup of the target website you want to scrape.
