Puppeteer is a powerful tool for web scraping and automated testing, but sometimes you may need to use a proxy to avoid being blocked or to access geo-restricted content. In this article, we will explore how to use Puppeteer proxy, set proxy, rotating proxy, and proxy-chain to enhance your web scraping capabilities. Puppeteer provides the ability to set up a proxy for your web scraping tasks. By using the 'puppeteer-extra-plugin-proxy' plugin, you can easily configure and use proxies with Puppeteer. This allows you to rotate through a list of proxies, making it more difficult for websites to detect and block your scraping activities. Additionally, the 'puppeteer-extra-plugin-anonymize-ua' plugin can be used to rotate user agents along with proxies, further enhancing your scraping capabilities. Another option for using proxies with Puppeteer is the 'proxy-chain' library, which provides a simple API for creating HTTP/HTTPS proxies. With proxy-chain, you can easily set up rotating proxies and manage proxy authentication. By combining Puppeteer with rotating proxies and proxy-chain, you can significantly improve the success rate of your web scraping efforts. In conclusion, using Puppeteer proxy, set proxy, rotating proxy, and proxy-chain can greatly enhance your web scraping capabilities, allowing you to access and extract data from websites more efficiently and reliably.
