Ad-hoc cors proxy

Simple reliable node-based cors proxy.

$ corsproxy www.target.com -p 8080
proxy to http://www.target.com started on port 8080

Why simple reliable? Because it just assembles two well tested and actively maintained middlewares: http-proxy and cors. It's a package you could have written yourself, but this one's ready to use with complete usage instructions (thanks to docopt).

Installation

local testing

$ npm install adhoc-cors-proxy

global install

$ npm install -g adhoc-cors-proxy

Usage

with local install

node bin <target> [--port=<port>] [--origin=<origin>] [--credentials]
node bin -h | --help | --version

with global install

corsproxy <target> [--port=<port>] [--origin=<origin>] [--credentials]
corsproxy -h | --help | --version

Options

-p <port>, --port=<port>        Port number. [default: 9292]
--host=<host>                   Host
-o <origin>, --origin=<origin>  Restrict origin domain
-c, --credentials               access-control-allow-credentials=true

Alternatively, the proxy can be configured entirely using environment variables. Check the sources for a better understanding of configuration priority.

Production

I recommend using Heroku's free tier or pm2 on a virtual-machine cloud-service.

Development

You can hack into this package by installing grunt

$ npm install -g grunt-cli

Starting the server and specifying the target has a slightly different syntax:

$ grunt --target=http://www.target.com -p 8080

Jshint will check your code and the proxy will restart everytime the sources are modified.
