    Parse query param value.

  8. parseQueryParamMaybe :: FromHttpApiData a => Text -> Maybe a

    http-api-data Web.HttpApiData

    Parse query param value in a Maybe.

Just True

  9. parseQueryParamWithPrefix :: FromHttpApiData a => Text -> Text -> Either Text a

    http-api-data Web.HttpApiData

    Case insensitive. Parse given text case insensitive and then parse the rest of the input using parseQueryParam.
