- route :: ToResponse r => Pattern -> Handler r -> App ()
Documentation
route :: ToResponse r => Pattern -> Handler r -> App () Source #
Run a handler on a matching route.
The handler may return any type which implements ToResponse
If a route matches any actions following it in the App monad will not be run.
Route patterns support pcre regex but do not yet support url parameters.
In the following example if we call helloHarry
then the helloHandler
will run, but NOT the helloHarryHandler since a matching route
ceases further execution.
For this reason the order you define your routes in matters.
app :: App () app = do route "/" indexHandler route "/hello.*" helloHandler route "/helloHarry" helloHarryHandler
