class ToSchema a where

Convert a type into Schema.

An example type and instance:

{-# LANGUAGE OverloadedStrings #-}   -- allows to write Text literals
{-# LANGUAGE OverloadedLists #-}     -- allows to write Map and HashMap as lists

import Control.Lens
import Data.Proxy
import Data.Swagger

data Coord = Coord { x :: Double, y :: Double }

instance ToSchema Coord where
  declareNamedSchema _ = do
    doubleSchema <- declareSchemaRef (Proxy :: Proxy Double)
    return $ NamedSchema (Just "Coord") $ mempty
      & type_ ?~ SwaggerObject
      & properties .~
          [ ("x", doubleSchema)
          , ("y", doubleSchema)
          ]
      & required .~ [ "x", "y" ]

Instead of manually writing your ToSchema instance you can use a default generic implementation of declareNamedSchema.

To do that, simply add deriving Generic clause to your datatype and declare a ToSchema instance for your datatype without giving definition for declareNamedSchema.

For instance, the previous example can be simplified into this:

{-# LANGUAGE DeriveGeneric #-}

import GHC.Generics (Generic)

data Coord = Coord { x :: Double, y :: Double } deriving Generic

instance ToSchema Coord

Minimal complete definition

Nothing

Methods

declareNamedSchema :: Proxy a -> Declare (Definitions Schema) NamedSchema

Convert a type into an optionally named schema together with all used definitions. Note that the schema itself is included in definitions only if it is recursive (and thus needs its definition in scope).

toNamedSchema :: ToSchema a => Proxy a -> NamedSchema

Convert a type into an optionally named schema.

>>> toNamedSchema (Proxy :: Proxy String) ^. name
Nothing
>>> encode (toNamedSchema (Proxy :: Proxy String) ^. schema)
"{\"type\":\"string\"}"

>>> toNamedSchema (Proxy :: Proxy Day) ^. name
Just "Day"

"{\"example\":\"2016-07-22\",\"format\":\"date\",\"type\":\"string\"}"

schemaName :: ToSchema a => Proxy a -> Maybe Text

Get type's schema name according to its ToSchema instance.

>>> schemaName (Proxy :: Proxy Int)
Nothing

>>> schemaName (Proxy :: Proxy UTCTime)
Just "UTCTime"

toSchema :: ToSchema a => Proxy a -> Schema

Convert a type into a schema.

>>> encode $ toSchema (Proxy :: Proxy Int8)
"{\"maximum\":127,\"minimum\":-128,\"type\":\"integer\"}"

>>> encode $ toSchema (Proxy :: Proxy [Day])
"{\"items\":{\"$ref\":\"#/definitions/Day\"},\"type\":\"array\"}"

toSchemaRef :: ToSchema a => Proxy a -> Referenced Schema

Convert a type into a referenced schema if possible. Only named schemas can be referenced, nameless schemas are inlined.

>>> encode $ toSchemaRef (Proxy :: Proxy Integer)
"{\"type\":\"integer\"}"

>>> encode $ toSchemaRef (Proxy :: Proxy Day)
"{\"$ref\":\"#/definitions/Day\"}"

declareSchemaRef :: ToSchema a => Proxy a -> Declare (Definitions Schema) (Referenced Schema)

Convert a type into a referenced schema if possible and declare all used schema definitions. Only named schemas can be referenced, nameless schemas are inlined.

Schema definitions are typically declared for every referenced schema. If declareSchemaRef returns a reference, a corresponding schema will be declared (regardless of whether it is recusive or not).

inlineSchemasWhen :: Data s => (Text -> Bool) -> Definitions Schema -> s -> s

Inline any referenced schema if its name satisfies given predicate.

NOTE: if a referenced schema is not found in definitions the predicate is ignored and schema stays referenced.

WARNING: inlineSchemasWhen will produce infinite schemas when inlining recursive schemas.

inlineSchemas :: Data s => [Text] -> Definitions Schema -> s -> s

Inline any referenced schema if its name is in the given list.

NOTE: if a referenced schema is not found in definitions it stays referenced even if it appears in the list of names.

WARNING: inlineSchemas will produce infinite schemas when inlining recursive schemas.

inlineAllSchemas :: Data s => Definitions Schema -> s -> s

Inline all schema references for which the definition can be found in Definitions.

WARNING: inlineAllSchemas will produce infinite schemas when inlining recursive schemas.

toInlinedSchema :: ToSchema a => Proxy a -> Schema

Convert a type into a schema without references.

>>> encode $ toInlinedSchema (Proxy :: Proxy [Day])
"{\"items\":{\"example\":\"2016-07-22\",\"format\":\"date\",\"type\":\"string\"},\"type\":\"array\"}"

WARNING: toInlinedSchema will produce infinite schema when inlining recursive schemas.

inlineNonRecursiveSchemas :: Data s => Definitions Schema -> s -> s

Inline all non-recursive schemas for which the definition can be found in Definitions.

binarySchema :: Schema

Default schema for binary data (any sequence of octets).

byteSchema :: Schema

Default schema for binary data (base64 encoded).

passwordSchema :: Schema

Default schema for password string. "password" format is used to hint UIs the input needs to be obscured.

sketchSchema :: ToJSON a => a -> Schema

Make an unrestrictive sketch of a Schema based on a ToJSON instance. Produced schema can be used for further refinement.

>>> encode $ sketchSchema "hello"

>>> encode $ sketchSchema (1, 2, 3)
"{\"example\":[1,2,3],\"items\":{\"type\":\"number\"},\"type\":\"array\"}"

>>> encode $ sketchSchema ("Jack", 25)
"{\"example\":[\"Jack\",25],\"items\":[{\"type\":\"string\"},{\"type\":\"number\"}],\"type\":\"array\"}"

>>> data Person = Person { name :: String, age :: Int } deriving (Generic)
>>> instance ToJSON Person
>>> encode $ sketchSchema (Person "Jack" 25)
"{\"required\":[\"name\",\"age\"],\"properties\":{\"name\":{\"type\":\"string\"},\"age\":{\"type\":\"number\"}},\"example\":{\"age\":25,\"name\":\"Jack\"},\"type\":\"object\"}"

sketchStrictSchema :: ToJSON a => a -> Schema

Make a restrictive sketch of a Schema based on a ToJSON instance. Produced schema uses as much constraints as possible.

>>> encode $ sketchStrictSchema "hello"

>>> encode $ sketchStrictSchema (1, 2, 3)
"{\"enum\":[[1,2,3]],\"items\":[{\"enum\":[1],\"maximum\":1,\"minimum\":1,\"multipleOf\":1,\"type\":\"number\"},{\"enum\":[2],\"maximum\":2,\"minimum\":2,\"multipleOf\":2,\"type\":\"number\"},{\"enum\":[3],\"maximum\":3,\"minimum\":3,\"multipleOf\":3,\"type\":\"number\"}],\"maxItems\":3,\"minItems\":3,\"type\":\"array\",\"uniqueItems\":true}"

toSchemaBoundedIntegral :: forall a. (Bounded a, Integral a) => Proxy a -> Schema

genericToNamedSchemaBoundedIntegral :: forall a d f. (Bounded a, Integral a, Generic a, Rep a ~ D1 d f, Datatype d) => SchemaOptions -> Proxy a -> NamedSchema

Default generic named schema for Bounded, Integral types.

genericDeclareNamedSchemaNewtype

Arguments

:: forall a d c s i inner. (Generic a, Datatype d, Rep a ~ D1 d (C1 c (S1 s (K1 i inner))))

=> SchemaOptions

How to derive the name.

-> (Proxy inner -> Declare (Definitions Schema) Schema)

How to create a schema for the wrapped type.

-> Proxy a

-> Declare (Definitions Schema) NamedSchema

Declare a named schema for a newtype wrapper.

declareSchemaBoundedEnumKeyMapping :: forall map key value. (Bounded key, Enum key, ToJSONKey key, ToSchema key, ToSchema value) => Proxy (map key value) -> Declare (Definitions Schema) Schema

Declare Schema for a mapping with Bounded Enum keys. This makes a much more useful schema when there aren't many options for key values.

>>> data ButtonState = Neutral | Focus | Active | Hover | Disabled deriving (Show, Bounded, Enum, Generic)
>>> instance ToJSON ButtonState
>>> instance ToSchema ButtonState
>>> instance ToJSONKey ButtonState where toJSONKey = toJSONKeyText (T.pack . show)

"{\"properties\":{\"Neutral\":{\"type\":\"string\"},\"Focus\":{\"type\":\"string\"},\"Active\":{\"type\":\"string\"},\"Hover\":{\"type\":\"string\"},\"Disabled\":{\"type\":\"string\"}},\"type\":\"object\"}"

Note: this is only useful when key is encoded with ToJSONKeyText. If it is encoded with ToJSONKeyValue then a regular schema for [(key, value)] is used.

toSchemaBoundedEnumKeyMapping :: forall map key value. (Bounded key, Enum key, ToJSONKey key, ToSchema key, ToSchema value) => Proxy (map key value) -> Schema
