[back to package description]Servant-Options

by requesting OPTIONS for routes that are about to be called.

Usage:
module MyApp where

import Servant
import Network.Wai.Middleware.Cors
import Network.Wai.Middleware.Servant.Options
app :: Application
app = logStdoutDev
$ cors (const $ Just policy)
$ provideOptions apiProxy
$ serve apiProxy apiServer
where
policy = simpleCorsResourcePolicy
{ corsRequestHeaders = [ "content-type" ] }
