A Bucketchain middleware for stateless CSRF protection without token.

Installation

Bower

Usage

server :: Effect Server
server = createServer $ middleware1 <<< middleware2

middleware1 :: Middleware
middleware1 = withCSRFProtection
  { host: "example.oreshinya.xyz"
  , origins: [ "http://example.oreshinya.xyz" ]
  }

middleware2 :: Middleware
middleware2 next = do
  http <- ask
  case requestMethod http, requestURL http of
    "POST", "/test" ->
      liftEffect $ Just <$> body "This is test."
    "GET", "/" ->
      liftEffect $ Just <$> body "This is text."
    _, _ ->

This middleware needs 3 headers:
