An HTTP proxy written with Node.js (think Squid)

Package Exports

  • proxy
  • proxy/dist/proxy.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (proxy) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

proxy

An HTTP proxy written with Node.js (think Squid)

This module provides standard "HTTP proxy" logic. You can script your own server using the proxy server API. Be sure to take a look at the "Examples" section below.

There is also a companion proxy(1) CLI tool, which spawns an HTTP(s) proxy server with the specified options.

You could think of proxy(1) as similar to some of the other popular open source HTTP proxy software:

Examples

Basic HTTP(s) proxy server

A basic HTTP(s) server with all the default options. All requests are allowed. CONNECT HTTP method works as well.

import * as http from 'http';
import { createProxy } from 'proxy';

const server = createProxy(http.createServer());
server.listen(3128, () => {
  var port = server.address().port;
  console.log('HTTP(s) proxy server listening on port %d', port);
});

CLI Tool Examples

The proxy(1) CLI tool can be used to spawn HTTP(s) proxy server instances with various options.

Port to bind to

Pass the -p/--port option to with a port number to specify a TCP port to bind to. Defaults to 3128 if none is specified.

$ proxy --port 8080

Custom Proxy-Authenticate command

Pass the -a/--authenticate switch with a command to execute when the client Proxy-Authorization header is given. This command determines whether or not the request is authorized based on the "exit code" of the command.

The relevant request authentication information is passed in as PROXY_AUTH_USERNAME, PROXY_AUTH_PASSWORD and PROXY_AUTH_SCHEME environment variables.

For example, to authorize "Basic" authentication with username "foo" and password "bar":

$ proxy --authenticate 'if \
    [ "$PROXY_AUTH_USERNAME" = "foo" ] && \
    [ "$PROXY_AUTH_PASSWORD" = "bar" ]; \
      then exit 0; \
    fi; \
    exit 1;'

Custom outgoing interface

Pass the -l/--local-address argument with an IP address of the network interface to send the outgoing requests through. It is the equivalent of setting a localAddress field in the options when calling http.request().

$ proxy --local-address 192.168.0.10
