Validate JSON values with Swagger Schema.

Documentation

validateToJSON :: forall a. (ToJSON a, ToSchema a) => a -> [ValidationError]

Validate ToJSON instance matches ToSchema for a given value. This can be used with QuickCheck to ensure those instances are coherent:

validateToJSON (x :: Int) == []

NOTE: validateToJSON does not perform string pattern validation. See validateToJSONWithPatternChecker.

validateToJSONWithPatternChecker :: forall a. (ToJSON a, ToSchema a) => (Pattern -> Text -> Bool) -> a -> [ValidationError]

Validate ToJSON instance matches ToSchema for a given value and pattern checker. This can be used with QuickCheck to ensure those instances are coherent.

For validation without patterns see validateToJSON.

validateJSON :: Definitions Schema -> Schema -> Value -> [ValidationError]

Validate JSON Value against Swagger Schema.

validateJSON mempty (toSchema (Proxy :: Proxy Int)) (toJSON (x :: Int)) == []

NOTE: validateJSON does not perform string pattern validation. See validateJSONWithPatternChecker.

validateJSONWithPatternChecker :: (Pattern -> Text -> Bool) -> Definitions Schema -> Schema -> Value -> [ValidationError]

Validate JSON Value agains Swagger ToSchema for a given value and pattern checker.

For validation without patterns see validateJSON.
