Ethical web data extraction via the best datacenter proxies, residential and mobile IPs is a mandatory stage of making well-considered business decisions. The choice of tools depends on the particular case, as well as programming methods or languages preferred by experts. The credible Dexodata infrastructure offers to buy residential and mobile proxies with SOCKS5 and HTTPS support and 100% compatibility with online scrapers and automation software in various programming languages.
The knowledge of Ruby stays one of the most well-paid hard skills on the IT market, according to the Stackoverflow survey. This language suits for internet scraping due to its object-oriented core and understandable syntax. Today, we will emphasize Ruby benefits for acquiring online knowledge.
Ruby is an interpreted, open-source computing language involved in almost 4 million sites’ architecture. Simplicity and versatility make this solution a part of both frontend and backend software development. Advantages of Ruby for web scraping include:
- Eloquent syntax
- Robust libraries
- Proxy servers management
- Rapid development
- Testing tenacity
- Multi-threading mastery
- CSS supremacy.
The following chapter is devoted to details and technologies comprising each of the listed strengths for obtaining internet insights via residential and mobile proxies one buys.
Object-oriented nature makes Ruby as a language easy-readable and highly-maintainable. It supports regular expressions for comparing and obtaining particular information from online sources along with tools to process strings, arrays, etc. Readability and expressiveness are achieved thanks to the plain English, which stands for simple coding with optional parentheses. Understandable method calls are allowed, in particular, for deploying free trial proxies and controlling them.
Ruby offers a treasure trove of libraries for online analytics where “gems” stands for additional frameworks operated by the RubyGems application. E.g. to install a library operating the best datacenter proxies, paste into console:
gem install faraday
Other extensions crucial for harvesting online insights include:
- Nokogiri to maintain HTML and XML
- Watir to automate browsers and make screenshots
- Capybara to simulate users’ actions via API
- RSelenium to exploit Selenium WebDriver
- MetaInspector to collect meta information from provided URL at once
- HTTParty to operate JSON and HTML requests.
The Faraday gem allows users to buy residential and mobile proxies, change external IPs, prescribe them to particular scraping threads, and pass authentication. This library assists in performing ethical web data harvesting on an expert level. Here is an example of leveraging intermediate IP addresses:
# Replace with your proxy server details
proxy_url = 'http://dexodata-proxy-server.com:port'
proxy_username = 'your-dexodata-username'
proxy_password = 'your-dexodata-password'
# Create a Faraday connection with proxy settings
conn = Faraday.new(url: 'https://example.com') do |faraday|
# Set the proxy URL
# Set up basic authentication with your proxy username and password
faraday.request :basic_auth, proxy_username, proxy_password
# Other connection settings as needed
# Make an HTTP request using the proxy
response = conn.get('/')
Ruby includes Rails, a versatile MVC framework allowing to develop web applications operating XML and JSON. Ruby on Rails interacts with target pages, captures, and operates gained knowledge through object-relational mapping (ORM), supports other libraries and proxy free trial’s features. That boosts scraping tool’s development and deployment.
The computing solution presents an integral testing ecosystem with gems like FakeWeb and Capybara. These addons facilitate comprehensive unit tests and additional internet crawling via Selenium or WebKit. Ask for a proxy free trial to test your project’s performance.
Ruby supports concurrent threads during automated internet objects’ extraction, parallelizing tasks. Through the Threads or Parallel libraries experts optimize efficiency applying the ‘map’ method. Such features unite the described language with Python which holds leading positions in collecting data online through the best datacenter proxies.
The Nokogiri gem wields exceptional support for CSS selectors and serves scraping objectives. Nokogiri can:
- Target specific elements on online platforms
- Handle complex HTML or XML sources due to XPath compatibility
- Support uncommon character encodings
- Integrate additional frameworks seamlessly.
