Driven by my burning desire to tunnel npm install requests through a SOCKSv5 proxy (eg. shadowsocks). Since npmonly support HTTP proxy, I wrote this simple command line module to fire up a HTTP Proxy server, then use it to tunnel requests to my SOCKS proxy.
Supports HTTP and HTTPS requests
Built-in DNS cache
150 loc, does nothing else
npm install kneesocks --production -g
kneesocks port1 port2, eg. kneesocks 10001 10002
port1 is the port your HTTP proxy server listen to on localhost.
port2 is the port of your existing SOCKS proxy, also on localhost.
Then you can set your npm config:
npm config set http http://127.0.0.1:10001
npm config set https-proxy http://127.0.0.1:10001
To revert proxy config, use npm config delete http and npm config delete https-proxy.
To debug, use DEBUG=proxy kneesocks port1 port2
Node v0.10+ required (Node v0.11+ preferred).
Probably not the best solution for day-to-day browsing, due to lack of remote dns and websocket support.
