What is Web Scraping?

Web scraping, also known as web harvesting, refers to the automated extraction of data from websites. This information is collected and then exported into a format that is more useful for the user.

Why is Web Scraping Important?

Web scraping is a powerful tool in today's data-driven world. It enables businesses to access a vast amount of publicly available data, which can provide them with the insights necessary to stay ahead of the competition, adapt to market trends, and make informed decisions.

What is a Worker System?

A worker system is a background process that performs tasks outside of the main flow of a web application. They handle asynchronous tasks, often queue-based, that run in the background without interfering with user interactions. Examples of worker systems include data processing, batch jobs, or even more complicated tasks like web scraping.

How Worker Systems Boost Web Scraping?

Worker systems enhance the functionality and efficiency of web scraping in various ways:

  1. Concurrency and Speed: Worker systems can concurrently process multiple tasks, leading to quicker data retrieval from a number of websites at the same time.
  2. Fault Tolerance: They ensure that if a process fails, it doesn't halt the entire scraping operation.
  3. Asynchronous processing: Worker systems execute a task in the background without interrupting the current application
  4. Scalability: As the amount of data to be scraped increases, worker systems can scale to meet the demands.

Five Real-world Use Cases of Web Scraping

1. Competitive Intelligence

Businesses scrape competitors' websites to understand their strategies, products, and pricing structures. This data can fuel competitive intelligence, enabling businesses to stay ahead.

2. Social Media Monitoring

Web scraping social media platforms can provide insights into customer sentiment and trending topics. Companies can leverage this information to make more informed business and marketing decisions.

3. SEO Monitoring

SEO experts scrape search engine results pages to understand keyword rankings and develop effective SEO strategies.

4. Real Estate Analysis

Web scraping real estate websites can yield data about property prices, trends, and market conditions, aiding real estate investors and firms in decision-making.

5. Weather Forecasting

Scraping weather websites for weather and temperature data can help create accurate and localized forecasts. These can be beneficial for a variety of sectors such as agriculture, retail, and logistics.

  2. Create Your Worker: Write the code for your worker in the language of your choice. Here's a Python snippet that scrapes a test website (example.com). In this example we’re scrapping the “h1” header:
    from bs4 import BeautifulSoup
    import requests
    
    def fetch_header(url):
        response = requests.get(url)
        soup = BeautifulSoup(response.text, 'html.parser')
        header = soup.find('h1').text
        return header
    
    url = "<http://example.com>"
    header = fetch_header(url)
    print(header)
    
  3. Install dependencies. Create the requirements.txt file with the following content:
    bs4
    requests
    

    Run this command to install dependencies into “packages” directory:

    docker run --rm -v "$PWD":/worker -w /worker iron/python:3.6-dev pip3 install -t packages -r requirements.txt
    
  4. Zip and Upload Your Worker. Run this command:
    zip -r web_scrapper.zip .
    iron worker upload --name web_scrapper --zip web_scrapper.zip iron/python:3.6 python web_scrapper.py
    
  5. Schedule or Run Your Worker: Set a schedule for your worker to run on a regular basis or manually trigger it as per your requirements:
    iron worker queue web_scrapper
