A programmable HTTP/HTTPS proxy server library for Node.js, similar to Squid, with support for SSL/TLS, SOCKS4/5, authentication, upstream proxy chaining, and custom HTTP responses. It is commonly used to let tools like headless Chrome and Puppeteer work with upstream proxies that require username/password authentication.

Use cases

• run a local proxy server so headless Chrome can use an authenticated upstream proxy
• chain multiple upstream proxies programmatically in Node.js
• build a custom HTTP/HTTPS proxy with dynamic authentication rules
• tunnel arbitrary protocols like HTTPS or FTP through an HTTP proxy
• intercept requests and return custom HTTP responses through a proxy
• collect traffic statistics through a programmable proxy

When to choose

• you need a proxy server whose authentication and chaining logic is defined in code and fully dynamic
• you use Puppeteer or headless Chrome with proxies that require credentials
• you need SOCKS4/5 and HTTP CONNECT tunneling support in a Node.js proxy
• you are building scraping infrastructure on top of residential or datacenter proxy pools

When to avoid

• you just need a simple static forward proxy with a config file - Squid or nginx may be simpler
• you need proxy protocols beyond Basic Proxy-Authorization
• your project is not on the Node.js platform
