Deepnest: Open-Source Web Scraping Framework

Deepnest is an open-source web scraping framework for JavaScript. It provides an easy API for extracting data from websites without requiring knowledge of browsers or HTML DOM. Deepnest handles cookies, headers, proxies, automation, and more out-of-the-box.

What is Deepnest?

Deepnest is an open-source web scraping framework built for JavaScript. It aims to make web scraping easy by abstracting away browser internals, HTML DOM handling, cookie and header management, proxies, and more.

Some key features of Deepnest include:

• Simple API - Just point Deepnest to a URL and tell it what data to extract. No need to work directly with the DOM.
• Headless Chromium under the hood - Deepnest launches headless Chrome browsers to render pages and extract data.
• Cookie persistence - Cookies are automatically persisted across page navigations for continuous scraping.
• Proxy support - Rotate proxies or use sticky sessions per browser instance.
• Extensible middleware - Plug in custom middleware for manipulation request/response flow.
• Async iterators - Page methods return async iterators for efficient large dataset scraping.
• Works across platforms - Run on Windows, Mac, Linux without configuration.

Deepnest makes it simple to integrate complex web scraping workflows into any JavaScript application. The headless browser basis provides resilience against obscurity techniques on modern websites. Overall it strikes a good balance between power and ease-of-use for web scraping via JavaScript.
