# Initialize Crawlbase API with your access token
crawling_api = CrawlingAPI({'token': 'YOUR_CRAWLBASE_TOKEN'})

def make_crawlbase_request(url):
    response = crawling_api.get(url)

    if response['headers']['pc_status'] == '200':
        html_content = response['body'].decode('utf-8')
        return html_content
    else:

Now, let’s get started with setting up your Python environment to scrape healthline.com.

Setting Up Your Python Environment

Before you start scraping healthline.com you need to set up your Python environment. This step will ensure that you have all the tools and libraries you need to run your scraper.

1. Install Python and Required Libraries

Download and install Python from the official Python website. Once Python is installed you can use pip, Python’s package manager, to install the libraries:

1
pip install crawlbase beautifulsoup4 pandas
  • Crawlbase: Handles the interaction with the Crawlbase Crawling API.
  • BeautifulSoup: For parsing HTML and extracting required data.
  • Pandas: Helps structure and store scraped data in CSV files or other formats.

2. Choose an IDE

An Integrated Development Environment (IDE) makes coding more efficient. Popular options include:

  • PyCharm: A powerful tool with debugging and project management features.
  • Visual Studio Code: Lightweight and beginner-friendly with plenty of extensions.
  • Jupyter Notebook: Ideal for testing and running small scripts interactively.

3. Create a New Project

Set up a project folder and create a Python file where you will write your scraper script. For example:

1
2
3
mkdir healthline_scraper
cd healthline_scraper
touch scraper.py

Once your environment is ready, you’re all set to start building your scraper for healthline.com. In the next sections, we’ll go step by step through writing the scraper for listing pages and article pages.

Scraping Healthline.com Articles Listings

To scrape article listings from healthline.com, we’ll use the Crawlbase Crawling API for dynamic JavaScript rendering. Let’s break this down step by step, with professional yet easy-to-understand code examples.

1. Inspecting the HTML Structure

Before writing code, open healthline.com and navigate to an article listing page. Use the browser’s developer tools (usually accessible by pressing F12) to inspect the HTML structure.

Example of an article link structure:

      data-element-event="INTERNAL LINK|SECTION|Any Page|SEARCH RESULTS|LINK|/health-news/antacids-increase-migraine-risk|"
      href="https://www.healthline.com/health-news/antacids-increase-migraine-risk"
    >
      <span class="ais-Highlight">
        <span class="ais-Highlight-nonHighlighted">Antacids Associated with Higher Risk of </span>
        <em class="ais-Highlight-highlighted">Migraine</em>
        <span class="ais-Highlight-nonHighlighted">, Severe Headaches</span>
      </span>
    </a>
  </div>
  <div class="css-1evntxy">
    <span class="ais-Highlight">
      <span class="ais-Highlight-nonHighlighted"
        >New research suggests that people who take antacids may be at greater risk for
      </span>
      <em class="ais-Highlight-highlighted">migraine</em>
      <span class="ais-Highlight-nonHighlighted"> attacks and severe headaches.</span>
    </span>
  </div>
</div>

Identify elements such as:

  • Article titles: Found in an a tag with class css-17zb9f8.
  • Links: Found in href attribute of an a tag.
  • Description: Found in an div element with class css-1evntxy.

2. Writing the Healthline.com Listing Scraper

We’ll use the Crawlbase Crawling API to fetch the page content and BeautifulSoup to parse it. We will use the ajax_wait and page_wait parameters provided by Crawlbase Crawling API to handle JS content. You can read about these parameters here.

options = {
    'ajax_wait': 'true',
    'page_wait': '5000'
}

def scrape_article_listings(url):
    response = crawling_api.get(url, options)

    if response['headers']['pc_status'] == '200':
        html_content = response['body'].decode('utf-8')
        soup = BeautifulSoup(html_content, 'html.parser')

        articles = []
        for item in soup.find_all('a', class_='article-link'):
            article_title = item.text.strip()
            article_url = "https://www.healthline.com" + item['href']
            articles.append({'title': article_title, 'url': article_url})

        return articles
    else:
        print(f"Failed to fetch the page: {response['headers']['pc_status']}")
        return []

# Example usage
url = "https://www.healthline.com/articles"
article_listings = scrape_article_listings(url)
print(article_listings)

3. Storing Data in a CSV File

You can use the pandas library to save the scraped data into a CSV file for easy access.

Scraping Healthline.com Article Page

After collecting the listing of articles, the next step is to scrape details from individual article pages. Each article page typically contains detailed content, such as the title, publication date, and main body text. Here’s how to extract this data efficiently using the Crawlbase Crawling API and Python.

1. Inspecting the HTML Structure

Open an article page from healthline.com in your browser and inspect the page source using developer tools (F12).

Healthline Articles Page Inspect

Look for:

  • Title: Found in <h1> tag with class css-6jxmuv.
  • Byline: Found in a div with attribute data-testid="byline".
  • Body Content: Found in article tag with class article-body.

2. Writing the Healthline.com Article Scraper
