By the end of this blog, you will have a deep understanding of how to scrape Alibaba effectively using both Puppeteer and Crawling API with Cheerio. This will allow you to select the most suitable approach based on your specific requirements and preferences.

III. What can you extract from Alibaba?

Before diving into the coding process, it's crucial to familiarize ourselves with the structure of the HTML page of Alibaba's Search Engine Results Page (SERP). By examining the HTML markup, we can identify the key elements necessary for extracting the following details programmatically. For the sake of this blog, we will use this Alibaba URL as an example.

To locate the data we want to scrape in the HTML code, we'll need to inspect the elements on the page using your web browser's developer tools. Here's a general guide on where you might find each piece of information:

1. Titles: Typically, the titles of products are contained within <h3>, <h4>, or similar heading tags within the product listings.
2. Price: Prices are often found within specific <div>, <span>, or <p> elements with a class or ID that indicates they contain price information. i. URL: The URLs of the product listings are usually contained within <a> (anchor) tags, commonly in the href attribute.
3. Product Images: Images are typically located within <img> tags, and the src attribute of these tags holds the URL of the image.
4. Store Name: Store names can be found within specific elements such as <div>, <span>, or <a> tags, often with a class or ID indicating they contain store information.
5. Store Link: Similar to the product URLs, store links are usually contained within <a> tags, typically in the href attribute.
6. Minimum Item: Information about minimum order quantities may vary in its location within the HTML code. Look for specific elements or text that indicate minimum order requirements.
7. Number of Results: This information is often displayed at the top or bottom of the search results page and may be within a <div> or other container with a unique identifier.

Once you identify the relevant HTML elements containing the data you need, you'll need to write code that selects these elements based on their structure, class names, IDs, or other attributes, and then retrieves the text or attribute values from those elements. We’ll show you how it’s done on the next part of this blog.

IV. Scraping using Puppeteer

In this section, we will guide you on how to use Puppeteer for scraping Alibaba's SERP. First, we need to set up a Node.js project and install the Puppeteer package. Follow the steps below:

1. Create a new directory for your project:

mkdir alibaba-serp-scraper

This command will create an empty folder named alibaba-serp-scraper.

1. Navigate into the newly created directory:

cd alibaba-serp-scraper && npm i puppeteer

By using this command we will navigate in the directory and install the puppeteer package including its dependencies into your project..

1. Create a new JavaScript file named index.js where we'll write the scraper's code:

touch index.js

This command creates an empty index.js file in the project directory where you can write your Puppeteer scraper code.

Now that we have set up our project and installed Puppeteer, we can proceed to write the scraper code in the index.js file to extract data from Alibaba's SERP.

Study the code below and copy it into your index.js file:

// Import required modules
const puppeteer = require('puppeteer'),
  fs = require('fs');

// Define an asynchronous function to scrape Bing search results
async function scrapeAlibabaSERP(searchString) {
  // Launch a headless browser
  const browser = await puppeteer.launch(),
    // Create a new page in the browser
    page = await browser.newPage();

  // Navigate to the Alibaba search results page for the specified search string
  await page.goto(`https://www.alibaba.com/trade/search?SearchText=${searchString.replaceAll(' ', '+')}`);

  // Wait for the selector ".seb-pagination" to ensure that the search results are loaded
  await page.waitForSelector('.seb-pagination');

  // Extract relevant data from the search results using page.evaluate
  const results = await page.evaluate(() => {
    // Map over each search result element to create an array of result objects
    return Array.from(document.querySelectorAll('.offer-list-wrapper .J-search-card-wrapper')).map((list, index) => ({
      position: index + 1,
      title: list.querySelector('[data-spm="d_title"]')?.textContent,
      url: `https:${list.querySelector("[data-spm='d_title']")?.getAttribute('href')}`,
      price: list.querySelector('.search-card-e-price-main')?.textContent,
      isVerified: list.querySelector('.verified-supplier-icon') ? true : false,
      image: `https:${list.querySelector('.search-card-e-slider__img')?.getAttribute('src')}`,
      minItem: list.querySelector('.search-card-m-sale-features__item')?.textContent,
      storeName: list.querySelector('.search-card-e-company')?.textContent,
      storeLink: `https:${list.querySelector('.search-card-e-company')?.getAttribute('href')}`,
      reviews: list.querySelector('.search-card-e-review')?.textContent,
    }));
  });
  numberOfResults = await page.evaluate(() => document.querySelector('.seb-refine-result_all')?.textContent);

  // Close the browser after scraping is complete
  await browser.close();

  // Log the results to the console
  console.log({ results, numberOfResults }, 'Result');

  // Write the results to a JSON file for further use
  fs.writeFileSync('alibaba-serp.json', JSON.stringify({ results, numberOfResults }, null, 2));

  // Return the scraped results
  return results;
}

// Call the function with a sample search string (e.g "samsung s24 ultra")
scrapeAlibabaSERP('samsung s24 ultra');

Execute the above code by using a simple command:

node index.js

This should provide you with the JSON data in an easily readable structure.

V. Why Use Crawlbase

When scraping websites, you may encounter bot detection measures, leading to your scraper being blocked eventually. To mitigate this risk, it's essential to hide your real IP address. While using a pool of proxies may get the job done, building and managing such a system on your own can be time-consuming and costly. This is where the Crawling API comes into play.

Crawlbase’s Crawling API is built on top of millions of Datacenter and Residential IPs, providing you with a diverse range of IP addresses to use for each request. This rotation of IP addresses helps avoid detection and enhances the scraping process. Additionally, the API is integrated with AI technology, enabling it to mimic basic human interaction with the target website effectively.

By utilizing the Crawling API, you can enhance your scraping capabilities, unblock websites, minimize the risk of blocks and CAPTCHAs, and ensure a smoother and more reliable scraping experience.

VI. Scrape using Crawling API and Cheerio

To utilize the Crawling API with the code we're creating, the initial step is to sign up and obtain the API key. Follow these steps:

1. Sign Up for Crawlbase API: Start by signing up for the Crawlbase API. Navigate to their website and follow the registration process to create an account.
2. Obtain API Credentials: After registering, obtain your API credentials from your account documentation. These credentials are essential for making requests to the Crawling API service.
3. API Key and Secret: Your API credentials typically consist of an API key and a secret key. These credentials authenticate your requests to the Crawling API service.
4. Keep Credentials Secure: Ensure that you keep your API credentials secure, as they are a crucial part of the web scraping process. Avoid sharing them publicly or exposing them in your code.

Once you have acquired the API tokens for the Crawling API, you can proceed with setting up the coding
environment using the following commands:

1. Create a Directory: This command creates a new directory named alibaba-serp-scraper where we'll organize our project files.

mkdir alibaba-serp-scraper

1. Navigate to the Directory: Move into the newly created directory to perform further actions.

cd alibaba-serp-scraper

1. Create JavaScript File: This command creates a new JavaScript file named index.js where we'll write our scraping code.

touch index.js

1. Install Dependencies: This command installs the necessary dependencies, including crawlbase for interacting with the Crawling API and cheerio for parsing HTML.

npm install crawlbase cheerio

Once done, you can now copy the code below and paste it in your index.js file. Make sure to study it first to understand each line.

// import Crawlbase Crawling API package
const { CrawlingAPI } = require('crawlbase'),
  cheerio = require('cheerio'),
  // Import the 'fs' module
  fs = require('fs');

// initializing Crawling API
const api = new CrawlingAPI({ token: 'Crawlbase_Token' }), // Replace it with your Crawlbase token
  // Alibaba SERP URL
  alibabaSerpURL = 'https://www.alibaba.com/trade/search?SearchText=samsung+s24+ultra';

// Crawling API get request execution
api
  .get(alibabaSerpURL)
  .then((response) => {
    // Function call to parse data from HTML response
    const scrapedData = parseDataFromHTML(response.body);

    // Writing scraped data to a JSON file
    fs.writeFileSync('alibaba_scraped.json', JSON.stringify({ scrapedData }, null, 2));
  })
  .catch((error) => {
    console.log(error, 'ERROR');
  });

// Function to parse data from HTML response
function parseDataFromHTML(html) {
  try {
    const $ = cheerio.load(html),
      scrapedData = {
        results: [],
        numberOfResults: '',
      };

    // Extracting number of results
    scrapedData['numberOfResults'] = $('.seb-refine-result_all').text().trim();
    $('.offer-list-wrapper .J-search-card-wrapper').each((_, element) => {
      // Extracting data for each search result
      const title = $(element).find("[data-spm='d_title']").text(),
        url = $(element).find("[data-spm='d_title']").attr('href'),
        price = $(element).find('.search-card-e-price-main').text(),
        image = $(element).find('.search-card-e-slider__img').attr('src'),
        minItem = $(element).find('.search-card-m-sale-features__item').text(),
        storeName = $(element).find('.search-card-e-company').text(),
        storeLink = $(element).find('.search-card-e-company').attr('href'),
        reviews = $(element).find('.search-card-e-review').text();

      // Pushing extracted data to results array
      scrapedData['results'].push({
        title,
        url: url.includes('http') ? url : `https:${url}`,
        price,
        image: image.includes('http') ? image : `https:${image}`,
        minItem,
        storeName,
        storeLink: storeLink.includes('http') ? storeLink : `https:${storeLink}`,
        reviews,
      });
    });

    return scrapedData;
  } catch (err) {
    return err;
  }
}

Again, you can execute the code by using the command below:

node index.js

This will provide a response in a readable JSON format structure.
