Synopsis

clientIn :: HasClient m api => Proxy api -> Proxy m -> Client m api Source #

clientIn allows you to produce operations to query an API from a client within a RunClient monad.

type MyApi = "books" :> Get '[JSON] [Book] -- GET /books
        :<|> "books" :> ReqBody '[JSON] Book :> Post '[JSON] Book -- POST /books

myApi :: Proxy MyApi
myApi = Proxy

clientM :: Proxy ClientM
clientM = Proxy

getAllBooks :: ClientM [Book]
postNewBook :: Book -> ClientM Book
(getAllBooks :<|> postNewBook) = myApi `clientIn` clientM

class RunClient m => HasClient m api where Source #

This class lets us define how each API combinator influences the creation of an HTTP request.

Unless you are writing a new backend for servant-client-core or new combinators that you want to support client-generation, you can ignore this class.

If you use a Capture in one of your endpoints in your API, the corresponding querying function will automatically take an additional argument of the type specified by your Capture.

You can control how values for this type are turned into text by specifying a ToHttpApiData instance for your type.

Example:

type MyApi = "books" :> Capture "isbn" Text :> Get '[JSON] Book

myApi :: Proxy MyApi

getBook :: Text -> ClientM Book
getBook = client myApi
-- then you can just use "getBook" to query that endpoint

If you use a CaptureAll in one of your endpoints in your API, the corresponding querying function will automatically take an additional argument of a list of the type specified by your CaptureAll. That function will take care of inserting a textual representation of this value at the right place in the request path.

You can control how these values are turned into text by specifying a ToHttpApiData instance of your type.

Example:

type MyAPI = "src" :> CaptureAll Text -> Get '[JSON] SourceFile

myApi :: Proxy

(KnownSymbol sym, ToHttpApiData a, HasClient m api, SBoolI (FoldRequired mods)) => HasClient m (Header' mods sym a :> api) Source #

If you use a Header in one of your endpoints in your API, the corresponding querying function will automatically take an additional argument of the type specified by your Header, wrapped in Maybe.

That function will take care of encoding this argument as Text in the request headers.

All you need is for your type to have a ToHttpApiData instance.

Example:

newtype Referer = Referer { referrer :: Text }
  deriving (Eq, Show, Generic, ToHttpApiData)

           -- GET /view-my-referer
type MyApi = "view-my-referer" :> Header "Referer" Referer :> Get '[JSON] Referer

myApi :: Proxy MyApi
myApi = Proxy

viewReferer :: Maybe Referer -> ClientM Book
viewReferer = client myApi
-- then you can just use "viewRefer" to query that endpoint
-- specifying Nothing or e.g Just "http://haskell.org/" as arguments

(KnownSymbol sym, HasClient m api) => HasClient m (QueryFlag sym :> api) Source #

If you use a QueryFlag in one of your endpoints in your API, the corresponding querying function will automatically take an additional Bool argument.

If you give False, nothing will be added to the query string.

Otherwise, this function will insert a value-less query string parameter under the name associated to your QueryFlag.

Example:

type MyApi = "books" :> QueryFlag "published" :> Get '[JSON] [Book]

myApi :: Proxy MyApi
myApi = Proxy

getBooks :: Bool -> ClientM [Book]
getBooks = client myApi
-- then you can just use "getBooks" to query that endpoint.
-- 'getBooksBy False' for all books
-- 'getBooksBy True' to only get _already published_ books

(KnownSymbol sym, ToHttpApiData a, HasClient m api, SBoolI (FoldRequired mods)) => HasClient m (QueryParam' mods sym a :> api) Source #

If you use a QueryParam in one of your endpoints in your API, the corresponding querying function will automatically take an additional argument of the type specified by your QueryParam, enclosed in Maybe.

If you give Nothing, nothing will be added to the query string.

If you give a non-Nothing value, this function will take care of inserting a textual representation of this value in the query string.

You can control how values for your type are turned into text by specifying a ToHttpApiData instance for your type.

Example:

type MyApi = "books" :> QueryParam "author" Text :> Get '[JSON] [Book]

myApi :: Proxy MyApi
myApi = Proxy

getBooksBy :: Maybe Text -> ClientM [Book]
getBooksBy = client myApi
-- then you can just use "getBooksBy" to query that endpoint.
-- 'getBooksBy Nothing' for all books
-- 'getBooksBy (Just "Isaac Asimov")' to get all books by Isaac Asimov

(KnownSymbol sym, ToHttpApiData a, HasClient m api) => HasClient m (QueryParams sym a :> api) Source #

If you use a QueryParams in one of your endpoints in your API, the corresponding querying function will automatically take an additional argument, a list of values of the type specified by your QueryParams.

If you give an empty list, nothing will be added to the query string.

Otherwise, this function will take care of inserting a textual representation of your values in the query string, under the same query string parameter name.

You can control how values for your type are turned into text by specifying a ToHttpApiData instance for your type.

Example:

type MyApi = "books" :> QueryParams "authors" Text :> Get '[JSON] [Book]

myApi :: Proxy MyApi
myApi = Proxy

getBooksBy :: [Text] -> ClientM [Book]
getBooksBy = client myApi
-- then you can just use "getBooksBy" to query that endpoint.
-- 'getBooksBy []' for all books
-- 'getBooksBy ["Isaac Asimov", "Robert A. Heinlein"]'

If you use a ReqBody in one of your endpoints in your API, the corresponding querying function will automatically take an additional argument of the type specified by your ReqBody. That function will take care of encoding this argument as JSON and of using it as the request body.

All you need is for your type to have a ToJSON instance.

Example:

type MyApi = "books" :> ReqBody '[JSON] Book :> Post '[JSON] Book

myApi :: Proxy MyApi
myApi = Proxy

addBook :: Book -> ClientM Book

(//) :: a -> (a -> b) -> b infixl 1 Source #

Helper to make code using records of clients more readable.

Can be mixed with (/:) for supplying arguments.

Example:

type Api = NamedRoutes RootApi

data RootApi mode = RootApi
  { subApi :: mode :- NamedRoutes SubApi
  , …
  } deriving Generic

data SubApi mode = SubApi
  { endpoint :: mode :- Get '[JSON] Person
  , …
  } deriving Generic

api :: Proxy API
api = Proxy

rootClient :: RootApi (AsClientT ClientM)
rootClient = client api

endpointClient :: ClientM Person
endpointClient = client // subApi // endpoint

(/:) :: (a -> b -> c) -> b -> a -> c infixl 2 Source #

Convenience function for supplying arguments to client functions when working with records of clients.

Intended to be used in conjunction with (//).

Example:

type Api = NamedRoutes RootApi

data RootApi mode = RootApi
  { subApi :: mode :- Capture "token" String :> NamedRoutes SubApi
  , hello :: mode :- Capture "name" String :> Get '[JSON] String
