added --proxy path@url command line argument

[talmobi]

eg: --proxy /api@http://localhost:3000/api

Proxies request to given url from given path (for example when proxying to API server)

working sample:

budo scripts/main.js --live --proxy /api@http://localhost:3030/api -- -t rollupify -t sassr -t babelify

Cool, thanks for PR! I've never used proxies, can you give an example of when it would come in handy? How do I test for it? Is that dependency going to add significant bloat to budo?

Cheers 🙌

This is something better solved with a middleware IMO. I actually made one for this express purpose: https://www.npmjs.com/package/middleware-proxy

That's what I did at first but grew bored of always writing a config. A simple --proxy command line is quick and does all that I need.

If you have any kind of backend or API that your front-end depends on you'd have to write a config to run the budo server in tandem (attach as middleware) with your backend. With the command line you could proxy directly to your backend/api without writing a config.

How do I test for it?

I could write tests for it. Basically could run an express app and see if the proxy works.

Is that dependency going to add significant bloat to budo?

It's a pretty thin lib with full proxy support, <1000LOC, http-proxy depends on;

https://github.com/nodejitsu/node-http-proxy/blob/master/package.json
"dependencies": { "eventemitter3": "1.x.x", "requires-port": "1.x.x" },

..You could move budo's request devDependency to dependencies and write a not really smaller and less complete (like what middleware-proxy does) proxy -- But request is a huge library and would add much more bloat if it were in dependencies.

I added tests and switched to using opts.proxy so it works like the others like --live. The tests uses a node.js http server as a temporary backend api to test against:

Ok so it appears travis passes on all node version except node version 0.8 - probably something to do with the http.createServer... I'll check

[EDIT]: It looks like http-proxy isn't supported on node v0.8 - is node v0.8 support important for anyone still?
