#ServiceProxy
###What is it? A small wrapper around request (https://github.com/mikeal/request) that eases proxying services.
###Example
myApp proxies all calls to myService with the same URL scheme used except for all calls proxied to myService have a "/service" prepended to the url.
#myApp.coffee
app.get '/service/resource', serviceController.proxy
app.post '/service/resource', serviceController.proxy
#serviceController.coffee
ServiceProxy = require 'service_proxy'
serviceProxy = new ServiceProxy {
host: "http://localhost:4001"
transformUrl: (host, path) ->
return host + path.replace "/service", ""
onError: (req, res) ->
res.send err.message, 500
}
module.exports.proxy = (req, res) ->
serviceProxy.proxy req, res, { requestOpts: {json: true} }
API
Can either be used as a static method:
ServiceProxy.proxy req, res, opts
or as a class as in the example above
Options
host: the hostname to proxy to (is not required, can be done in transformUrl) transformUrl: a function that returns the route to the service, gets passed the host and request path onError: a function to run when a pipe error occurs requestOpts: a hash of options to be passed to request
