    Check-proxy - Advanced Node proxy testing library

    This is an advanced proxy checking library that powers https://gimmeproxy.com

    What it does:

    • checks http, socks4 and socks5 proxies
    • performs actual requests, not just pings
    • checks GET, POST, COOKIES, referer support
    • checks https support
    • checks country
    • checks proxy speed - provides total time and connect time
    • checks anonymity (binary checks - anonymous or not, 1 - anonymous, i.e. doesn't leak your IP address in any of the headers, 0 - not anonymous)
    • checks if proxy supports particular websites - by custom function, regex or substring search
    • allows to set connect timeout and overall timeout

    It will return a promise that is either fulfilled with an array of working proxies and protocols (some proxies support SOCKS4/SOCKS5 on the same port) or rejected if it wasn't able to connect to provided port.

    Installation

      npm install check-proxy --save

    Usage

    Library consists of two parts - client and server. Server runs on a known IP address and client tries to connect to server through proxy you provide.

    This allows to reliably check proxy parameters like GET, POST, COOKIES support. See example directory for server app.

    Additionally it's possible to check if particular websites are working through this proxy. Websites are checked against specified function, regex or string.
