synopsis: Display capture hints in router layout
|
||||
prs: #1556
|
||||
|
||||
description: {
|
||||
|
||||
This PR enhances the `Servant.Server.layout` function, which produces a textual description of the routing layout of an API. More precisely, it changes `<capture>` blocks, so that they display the name and type of the variable being captured instead.
|
||||
|
||||
Example:
|
||||
|
||||
For the following API
|
||||
```haskell
|
||||
type API =
|
||||
"a" :> "d" :> Get '[JSON] NoContent
|
||||
:<|> "b" :> Capture "x" Int :> Get '[JSON] Bool
|
||||
:<|> "a" :> "e" :> Get '[JSON] Int
|
||||
```
|
||||
|
||||
we previously got the following output:
|
||||
|
||||
```
|
||||
/
|
||||
├─ a/
|
||||
│ ├─ d/
|
||||
│ │ └─•
|
||||
│ └─ e/
|
||||
│ └─•
|
||||
└─ b/
|
||||
└─ <capture>/
|
||||
├─•
|
||||
┆
|
||||
└─•
|
||||
```
|
||||
|
||||
now we get:
|
||||
|
||||
```
|
||||
/
|
||||
├─ a/
|
||||
│ ├─ d/
|
||||
│ │ └─•
|
||||
│ └─ e/
|
||||
│ └─•
|
||||
└─ b/
|
||||
└─ <x::Int>/
|
||||
├─•
|
||||
┆
|
||||
└─•
|
||||
```
|
||||
|
||||
This change is achieved by the introduction of a CaptureHint type, which is passed as an extra argument to the CaptureRouter and CaptureAllRouter constructors for the Router' type.
|
||||
CaptureHint values are then used in routerLayout, to display the name and type of captured values, instead of just `<capture>` previously.
|
||||
|
||||
N.B.:
|
||||
Because the choice smart constructor for routers can aggregate Capture combinators with different capture hints, the Capture*Router constructors actually take a list of CaptureHint, instead of a single one.
|
||||
|
||||
This PR also introduces Spec tests for the routerLayout function.
|
||||
|
||||
Warning:
|
||||
This change is potentially breaking, because it adds the constraint `Typeable a` to all types that are to be captured. Because all types are typeable since GHC 7.10, this is not as bad as it sounds ; it only break expressions where `a` is quantified in an expression with `Capture a`.
|
||||
In those cases, the fix is easy: it suffices to add `Typeable a` to the left-hand side of the quantification constraint.
|
||||
|
||||
For instance, the following code will no longer compile:
|
||||
```haskell
|
||||
type MyAPI a = Capture "foo" a :> Get '[JSON] ()
|
||||
|
||||
myServer :: forall a. Server (MyAPI a)
|
||||
myServer = const $ return ()
|
||||
|
||||
myApi :: forall a. Proxy (MyAPI a)
|
||||
myApi = Proxy
|
||||
|
||||
app :: forall a. (FromHttpApiData a) => Application
|
||||
app = serve (myApi @a) (myServer @a)
|
||||
```
|
||||
|
||||
Indeed, `app` should be replaced with:
|
||||
```haskell
|
||||
app :: forall a. (FromHttpApiData a, Typeable a) => Application
|
||||
app = serve (myApi @a) (myServer @a)
|
||||
```
|
||||
}

synopsis: Encode captures using toEncodedUrlPiece
|

prs: #1569
|
||||
issues: #1511
|
||||
|
||||
description: {
|
||||
The `servant-client` library now makes direct use of `toEncodedUrlPiece` from `ToHttpApiData`
|
||||
to encode captured values when building the request path. It gives user freedom to implement
|
||||
URL-encoding however they need.
|
||||
|
||||
Previous behavior was to use `toUrlPiece` and URL-encode its output using `toEncodedUrlPiece`
|
||||
from the `Text` instance of `ToHttpApiData`. The issue with this approach is that
|
||||
`ToHttpApiData Text` is overly zealous and also encodes characters, such as `*`, which are perfectly valid in a URL.

# Using generics

module Main (main, api, getLink, routesLinks, cliGet) where
|
||||
|
||||
import Control.Exception (throwIO)
|
||||
import Control.Monad.Trans.Reader (ReaderT, runReaderT)
|
||||
import Data.Proxy (Proxy (..))
|
||||
import Network.Wai.Handler.Warp (run)
|
||||
import System.Environment (getArgs)
|
||||
|
||||
import Servant
|
||||
import Servant.Client
|
||||
|
||||
import Servant.API.Generic
|
||||
import Servant.Client.Generic
|
||||
import Servant.Server.Generic
|
||||
```
|
||||
|
||||
The usage is simple, if you only need a collection of routes.
|
||||
First you define a record with field types prefixed by a parameter `route`:
|
||||
|
||||
```haskell
|
||||
data Routes route = Routes
|
||||
{ _get :: route :- Capture "id" Int :> Get '[JSON] String
|
||||
, _put :: route :- ReqBody '[JSON] Int :> Put '[JSON] Bool
|
||||
}
|
||||
deriving (Generic)
|
||||
```
|
||||
|
||||
Then we'll use this data type to define API, links, server and client.
|
||||
|
||||
## API
|
||||
|
||||
You can get a `Proxy` of the API using `genericApi`:
|
||||
|
||||
```haskell
|
||||
api :: Proxy (ToServantApi Routes)
|
||||
api = genericApi (Proxy :: Proxy Routes)
|
||||
```
|
||||
|
||||
It's recommended to use `genericApi` function, as then you'll get
|
||||
better error message, for example if you forget to `derive Generic`.
|
||||
|
||||
## Links
|
||||
|
||||
The clear advantage of record-based generics approach, is that
|
||||
we can get safe links very conveniently. We don't need to define endpoint types,
|
||||
as field accessors work as proxies:
|
||||
|
||||
```haskell
|
||||
getLink :: Int -> Link
|
||||
getLink = fieldLink _get
|
||||
```
|
||||
|
||||
We can also get all links at once, as a record:
|
||||
|
||||
```haskell
|
||||
routesLinks :: Routes (AsLink Link)
|
||||
routesLinks = allFieldLinks
|
||||
```
|
||||
|
||||
## Client
|
||||
|
||||
Even more power starts to show when we generate a record of client functions.
|
||||
Here we use `genericClientHoist` function, which lets us simultaneously
|
||||
hoist the monad, in this case from `ClientM` to `IO`.
|
||||
|
||||
```haskell
|
||||
cliRoutes :: Routes (AsClientT IO)
|
||||
cliRoutes = genericClientHoist
|
||||
(\x -> runClientM x env >>= either throwIO return)
|
||||
where
|
||||
env = error "undefined environment"
|
||||
|
||||
cliGet :: Int -> IO String
|
||||
cliGet = _get cliRoutes
|
||||
```
|
||||
|
||||
## Server
|
||||
|
||||
Finally, probably the most handy usage: we can convert record of handlers into
|
||||
the server implementation:
|
||||
|
||||
```haskell
|
||||
record :: Routes AsServer
|
||||
record = Routes
|
||||
{ _get = return . show
|
||||
, _put = return . odd
|
||||
}
|
||||
|
||||
app :: Application
|
||||
app = genericServe record
|
||||
|
||||
main :: IO ()
|
||||
main = do
|
||||
args <- getArgs
|
||||
case args of
|
||||
("run":_) -> do
|
||||
putStrLn "Starting cookbook-generic at http://localhost:8000"
|
||||
run 8000 app
|
||||
-- see this cookbook below for custom-monad explanation
|
||||
("run-custom-monad":_) -> do
|
||||
putStrLn "Starting cookbook-generic with a custom monad at http://localhost:8000"
|
||||
run 8000 (appMyMonad AppCustomState)
|
||||
_ -> putStrLn "To run, pass 'run' argument: cabal new-run cookbook-generic run"
|
||||
```
|
||||
|
||||
## Using generics together with a custom monad
|
||||
|
||||
If your app uses a custom monad, here's how you can combine it with
|
||||
generics.
|
||||
|
||||
```haskell
|
||||
data AppCustomState =
|
||||
AppCustomState
|
||||
|
||||
type AppM = ReaderT AppCustomState Handler
|
||||
|
||||
apiMyMonad :: Proxy (ToServantApi Routes)
|
||||
apiMyMonad = genericApi (Proxy :: Proxy Routes)
|
||||
|
||||
getRouteMyMonad :: Int -> AppM String
|
||||
getRouteMyMonad = return . show
|
||||
|
||||
putRouteMyMonad :: Int -> AppM Bool
|
||||
putRouteMyMonad = return . odd
|
||||
|
||||
recordMyMonad :: Routes (AsServerT AppM)
|
||||
recordMyMonad = Routes {_get = getRouteMyMonad, _put = putRouteMyMonad}
|
||||
|
||||
-- natural transformation
|
||||
nt :: AppCustomState -> AppM a -> Handler a
|
||||
nt s x = runReaderT x s
|
||||
|
||||
appMyMonad :: AppCustomState -> Application
|
||||
appMyMonad state = genericServeT (nt state) recordMyMonad

# Request-lifetime Managed Resources
|
||||
|
||||
Let's see how we can write a handle that uses a resource managed by Servant. The resource is created automatically by Servant when the server recieves a request, and the resource is automatically destroyed when the server is finished handling a request.
|
||||
|
||||
As usual, we start with a little bit of throat clearing.
|
||||
|
||||
|
||||
``` haskell
|
||||
{-# LANGUAGE DataKinds #-}
|
||||
{-# LANGUAGE TypeOperators #-}
|
||||
import Control.Concurrent
|
||||
import Control.Exception (bracket, throwIO)
|
||||
import Control.Monad.IO.Class
|
||||
import Control.Monad.Trans.Resource
|
||||
import Data.Acquire
|
||||
import Network.HTTP.Client (newManager, defaultManagerSettings)
|
||||
import Network.Wai.Handler.Warp
|
||||
import Servant
|
||||
import Servant.Client
|
||||
import System.IO
|
||||
```
|
||||
|
||||
Here we define an API type that uses the `WithResource` combinator. The server handler for an endpoint with a `WithResource res` component will receive a value of that type as an argument.
|
||||
|
||||
``` haskell
|
||||
type API = WithResource Handle :> ReqBody '[PlainText] String :> Post '[JSON] NoContent
|
||||
|
||||
api :: Proxy API
|
||||
api = Proxy
|
||||
```
|
||||
|
||||
But this resource value has to come from somewhere. Servant obtains the value using an Acquire provided in the context. The Acquire knows how to both create and destroy resources of a particular type.
|
||||
|
||||
``` haskell
|
||||
appContext :: Context '[Acquire Handle]
|
||||
appContext = acquireHandle :. EmptyContext
|
||||
|
||||
acquireHandle :: Acquire Handle
|
||||
acquireHandle = mkAcquire newHandle closeHandle
|
||||
|
||||
newHandle :: IO Handle
|
||||
newHandle = do
|
||||
putStrLn "opening file"
|
||||
h <- openFile "test.txt" AppendMode
|
||||
putStrLn "opened file"
|
||||
return h
|
||||
|
||||
closeHandle :: Handle -> IO ()
|
||||
closeHandle h = do
|
||||
putStrLn "closing file"
|
||||
hClose h
|
||||
putStrLn "closed file"
|
||||
```
|
||||
|
||||
Now we create the handler which will use this resource. This handler will write the request message to the System.IO.Handle which was provided to us. In some situations the handler will succeed, but in some in will fail. In either case, Servant will clean up the resource for us.
|
||||
|
||||
``` haskell
|
||||
server :: Server API
|
||||
server = writeToFile
|
||||
|
||||
where writeToFile :: (ReleaseKey, Handle) -> String -> Handler NoContent
|
||||
writeToFile (_, h) msg = case msg of
|
||||
"illegal" -> error "wait, that's illegal!"
|
||||
legalMsg -> liftIO $ do
|
||||
putStrLn "writing file"
|
||||
hPutStrLn h legalMsg
|
||||
putStrLn "wrote file"
|
||||
return NoContent
|
||||
```
|
||||
|
||||
Finally we run the server in the background while we post messages to it.
|
||||
|
||||
``` haskell
|
||||
runApp :: IO ()
|
||||
runApp = run 8080 (serveWithContext api appContext $ server)
|
||||
|
||||
postMsg :: String -> ClientM NoContent
|
||||
postMsg = client api
|
||||
|
||||
main :: IO ()
|
||||
main = do
|
||||
mgr <- newManager defaultManagerSettings
|
||||
bracket (forkIO $ runApp) killThread $ \_ -> do
|
||||
ms <- flip runClientM (mkClientEnv mgr (BaseUrl Http "localhost" 8080 "")) $ do
|
||||
liftIO $ putStrLn "sending hello message"
|
||||
_ <- postMsg "hello"
|
||||
liftIO $ putStrLn "sending illegal message"
|
||||
_ <- postMsg "illegal"
|
||||
liftIO $ putStrLn "done"
|
||||
print ms
|
||||
```
|
||||
|
||||
This program prints
|
||||
|
||||
```
|
||||
sending hello message
|
||||
opening file
|
||||
opened file
|
||||
writing file
|
||||
wrote file
|
||||
closing file
|
||||
closed file
|
||||
sending illegal message
|
||||
opening file
|
||||
opened file
|
||||
closing file
|
||||
closed file
|
||||
wait, that's illegal!
|
||||
CallStack (from HasCallStack):
|
||||
error, called at ManagedResource.lhs:63:24 in main:Main
|
||||
Left (FailureResponse (Request {requestPath = (BaseUrl {baseUrlScheme = Http, baseUrlHost = "localhost", baseUrlPort = 8080, baseUrlPath = ""},""), requestQueryString = fromList [], requestBody = Just ((),text/plain;charset=utf-8), requestAccept = fromList [], requestHeaders = fromList [], requestHttpVersion = HTTP/1.1, requestMethod = "POST"}) (Response {responseStatusCode = Status {statusCode = 500, statusMessage = "Internal Server Error"}, responseHeaders = fromList [("Transfer-Encoding","chunked"),("Date","Thu, 24 Nov 2022 21:04:47 GMT"),("Server","Warp/3.3.23"),("Content-Type","text/plain; charset=utf-8")], responseHttpVersion = HTTP/1.1, responseBody = "Something went wrong"}))
|
||||
```
|
||||
|
||||
and appends to a file called `test.txt`. We can see from the output that when a legal message is sent, the file is opened, written to, and closed. We can also see that when an illegal message is sent, the file is opened but not written to. Crucially, it is still closed even though the handler threw an exception.

# NamedRoutes - Using records to define APIs
|
||||
|
||||
*Available in Servant 0.19 or higher*
|
||||
|
||||
Servant offers a very natural way of constructing APIs with nested records, called `NamedRoutes`.
|
||||
|
||||
This cookbook explains how to implement such nested-record-APIs using `NamedRoutes` through the example of a Movie Catalog.
|
||||
|
||||
First, we start by constructing the domain types of our Movie Catalog.
|
||||
After, we show you how to implement the API type with the NamedRoutes records.
|
||||
Lastly, we make a Server and a Client out of the API type.
|
||||
|
||||
However, it should be understood that this cookbook does _not_ dwell on the built-in servant combinators as the [<Structuring APIs> cookbook ](<https://docs.servant.dev/en/stable/cookbook/structuring-apis/StructuringApis.html>) already covers that angle.
|
||||
|
||||
## Why would I want to use `NamedRoutes` over the alternative `:<|>` operator?
|
||||
|
||||
With `NamedRoutes`, we don’t need to care about the declaration order of the endpoints.
|
||||
For example, with the `:<|>` operator there’s room for error when the order of the API type
|
||||
|
||||
```haskell,ignore
|
||||
type API1 = "version" :> Get '[JSON] Version
|
||||
:<|> "movies" :> Get '[JSON] [Movie]
|
||||
```
|
||||
|
||||
does not follow the `Handler` implementation order
|
||||
|
||||
```haskell,ignore
|
||||
apiHandler :: ServerT API1 Handler
|
||||
apiHandler = getMovies
|
||||
:<|> getVersion
|
||||
```
|
||||
|
||||
GHC could scold you with a very tedious message such as :
|
||||
|
||||
```console
|
||||
• Couldn't match type 'Handler NoContent'
|
||||
with 'Movie -> Handler NoContent'
|
||||
Expected type: ServerT MovieCatalogAPI Handler
|
||||
Actual type: Handler Version
|
||||
:<|> ((Maybe SortBy -> Handler [Movie])
|
||||
:<|> ((MovieId -> Handler (Maybe Movie))
|
||||
:<|> ((MovieId -> Movie -> Handler NoContent)
|
||||
:<|> (MovieId -> Handler NoContent))))
|
||||
• In the expression:
|
||||
versionHandler
|
||||
:<|>
|
||||
movieListHandler
|
||||
:<|>
|
||||
getMovieHandler :<|> updateMovieHandler :<|> deleteMovieHandler
|
||||
In an equation for 'server':
|
||||
server
|
||||
= versionHandler
|
||||
:<|>
|
||||
movieListHandler
|
||||
:<|>
|
||||
getMovieHandler :<|> updateMovieHandler :<|> deleteMovieHandler
|
||||
|
|
||||
226 | server = versionHandler
|
||||
```
|
||||
|
||||
On the contrary, with the `NamedRoutes` technique, we refer to the routes by their name:
|
||||
|
||||
```haskell,ignore
|
||||
data API mode = API
|
||||
{ list :: "list" :> ...
|
||||
, delete :: "delete" :> ...
|
||||
}
|
||||
```
|
||||
|
||||
and GHC follows the lead :
|
||||
|
||||
```console
|
||||
• Couldn't match type 'NoContent' with 'Movie'
|
||||
Expected type: AsServerT Handler :- Delete '[JSON] Movie
|
||||
Actual type: Handler NoContent
|
||||
• In the 'delete' field of a record
|
||||
In the expression:
|
||||
MovieAPI
|
||||
{get = getMovieHandler movieId,
|
||||
update = updateMovieHandler movieId,
|
||||
delete = deleteMovieHandler movieId}
|
||||
In an equation for 'movieHandler':
|
||||
movieHandler movieId
|
||||
= MovieAPI
|
||||
{get = getMovieHandler movieId,
|
||||
update = updateMovieHandler movieId,
|
||||
delete = deleteMovieHandler movieId}
|
||||
|
|
||||
252 | , delete = deleteMovieHandler movieId
|
||||
```
|
||||
|
||||
So, NamedRoutes is more readable for a human, and GHC gives you more accurate error messages.
|
||||
|
||||
What are we waiting for?
|
||||
|
||||
|
||||
## Boilerplate time!
|
||||
|
||||
First, let’s get rid of the the extensions and imports boilerplate in order to focus on our new technique:
|
||||
|
||||
|
||||
```haskell
|
||||
{-# LANGUAGE DataKinds #-}
|
||||
{-# LANGUAGE DeriveAnyClass #-}
|
||||
{-# LANGUAGE DerivingStrategies #-}
|
||||
{-# LANGUAGE DeriveGeneric #-}
|
||||
{-# LANGUAGE OverloadedStrings #-}
|
||||
{-# LANGUAGE TypeOperators #-}
|
||||
|
||||
import GHC.Generics ( Generic )
|
||||
import Data.Aeson ( FromJSON, ToJSON )
|
||||
import Data.Proxy ( Proxy(..) )
|
||||
import Network.Wai.Handler.Warp ( run )
|
||||
|
||||
import Servant ( NamedRoutes
|
||||
, Handler, serve )
|
||||
import Servant.API (Capture, Delete, Get, Put, QueryParam, ReqBody
|
||||
, JSON, NoContent (..)
|
||||
, FromHttpApiData (..),ToHttpApiData(..)
|
||||
, (:>) )
|
||||
import Servant.API.Generic ( (:-) )
|
||||
|
||||
import Servant.Client ( AsClientT, ClientM, client
|
||||
, (//), (/:) )
|
||||
import Servant.Client.Generic ()
|
||||
|
||||
import Servant.Server ( Application, ServerT )
|
||||
import Servant.Server.Generic ( AsServerT )
|
||||
|
||||
```
|
||||
|
||||
## Domain context
|
||||
|
||||
Now that we’ve handled the boilerplate, we can dive into our Movie Catalog domain.
|
||||
|
||||
Consider a `Movie` constructed from a `Title` and a `Year` of publication.
|
||||
|
||||
``` haskell
|
||||
data Movie = Movie
|
||||
{ movieId :: MovieId
|
||||
, title :: Title
|
||||
, year :: Year
|
||||
}
|
||||
deriving stock Generic
|
||||
deriving anyclass (FromJSON, ToJSON)
|
||||
|
||||
type MovieId = String
|
||||
type Title = String
|
||||
type Year = Int
|
||||
|
||||
```
|
||||
|
||||
|
||||
Let’s forget about the deriving stuff for now and think about the API that we want to make.
|
||||
|
||||
```
|
||||
"version" -> Get Version
|
||||
/
|
||||
api "list" -> Get [Movie] ?sortBy= Title | Year (sort by the Title or the Year)
|
||||
\ /
|
||||
"movies" Get Movie
|
||||
\ /
|
||||
Capture MovieId - Put Movie
|
||||
\
|
||||
Delete MovieId
|
||||
```
|
||||
|
||||
In this example, we create a very simple endpoint for the Version,
|
||||
and several complex endpoints that use nested records for the CRUD part of the movie.
|
||||
|
||||
So, the URLs would look like
|
||||
|
||||
- GET …/version
|
||||
- GET …/movies/list?sortby=Title
|
||||
- GET …/movies/<MovieId>/
|
||||
- PUT …/movies/<MovieId>/
|
||||
- DELETE …/movies/<MovieId>
|
||||
|
||||
### API Type
|
||||
|
||||
Now that we have a very clear idea of the API we want to make, we need to transform it into usable Haskell code:
|
||||
|
||||
``` haskell
|
||||
|
||||
data API mode = API
|
||||
{ version :: mode :- "version" :> Get '[JSON] Version
|
||||
, movies :: mode :- "movies" :> NamedRoutes MoviesAPI
|
||||
} deriving stock Generic
|
||||
|
||||
type Version = String -- This will do for the sake of example.
|
||||
|
||||
```
|
||||
Here, we see the first node of our tree. It contains the two branches “version” and “movies” respectively:
|
||||
|
||||
The “version” branch is very simple and self-explanatory.
|
||||
The “movies” branch will contain another node, represented by another record (see above). That is why we need the `NameRoutes` helper.
|
||||
|
||||
Note:
|
||||
|
||||
The `mode` type parameter indicates into which implementation the record’s `Generic` representation will be transformed—as a client or as a server. We will discuss that later.
|
||||
|
||||
Let's jump into the "movies" subtree node:
|
||||
|
||||
|
||||
``` haskell
|
||||
|
||||
data MoviesAPI mode = MoviesAPI
|
||||
{ list :: mode :- "list" :> QueryParam "SortBy" SortBy :> Get '[JSON] [Movie]
|
||||
, movie :: mode :- Capture "movieId" MovieId :> NamedRoutes MovieAPI
|
||||
} deriving stock Generic
|
||||
|
||||
data SortBy = Year | Title
|
||||
|
||||
instance ToHttpApiData SortBy where
|
||||
toQueryParam Year = "year"
|
||||
toQueryParam Title = "title"
|
||||
|
||||
instance FromHttpApiData SortBy where
|
||||
parseQueryParam "year" = Right Year
|
||||
parseQueryParam "title" = Right Title
|
||||
parseQueryParam param = Left $ param <> " is not a valid value"
|
||||
|
||||
```
|
||||
So, remember, this type represents the `MoviesAPI` node that we’ve connected earlier to the main `API` tree.
|
||||
|
||||
In this subtree, we illustrated both an endpoint with a **query param** and also, a **capture** with a subtree underneath it.
|
||||
|
||||
So, let's go deeper into our API tree.
|
||||
|
||||
``` haskell
|
||||
data MovieAPI mode = MovieAPI
|
||||
{ get :: mode :- Get '[JSON] (Maybe Movie)
|
||||
, update :: mode :- ReqBody '[JSON] Movie :> Put '[JSON] NoContent
|
||||
, delete :: mode :- Delete '[JSON] NoContent
|
||||
} deriving stock Generic
|
||||
```
|
||||
|
||||
As you can see, we end up implementing the deepest routes of our API.
|
||||
|
||||
Small detail: as our main API tree is also a record, we need the `NamedRoutes` helper.
|
||||
To improve readability, we suggest you create a type alias:
|
||||
|
||||
``` haskell
|
||||
type MovieCatalogAPI = NamedRoutes API
|
||||
```
|
||||
|
||||
That's it, we have our `MovieCatalogAPI` type!
|
||||
|
||||
Let's make a server and a client out of it!
|
||||
|
||||
### The Server
|
||||
|
||||
As you know, we can’t talk about a server, without addressing the handlers.
|
||||
|
||||
First, we take our handlers…
|
||||
|
||||
```haskell
|
||||
versionHandler :: Handler Version
|
||||
versionHandler = pure "0.0.1"
|
||||
|
||||
movieListHandler :: Maybe SortBy -> Handler [Movie]
|
||||
movieListHandler _ = pure moviesDB
|
||||
|
||||
moviesDB :: [Movie]
|
||||
moviesDB =
|
||||
[ Movie "1" "Se7en" 1995
|
||||
, Movie "2" "Minority Report" 2002
|
||||
, Movie "3" "The Godfather" 1972
|
||||
]
|
||||
|
||||
getMovieHandler :: MovieId -> Handler (Maybe Movie)
|
||||
getMovieHandler requestMovieId = go moviesDB
|
||||
where
|
||||
go [] = pure Nothing
|
||||
go (movie:ms) | movieId movie == requestMovieId = pure $ Just movie
|
||||
go (m:ms) = go ms
|
||||
|
||||
updateMovieHandler :: MovieId -> Movie -> Handler NoContent
|
||||
updateMovieHandler requestedMovieId newMovie =
|
||||
-- update the movie list in the database...
|
||||
pure NoContent
|
||||
|
||||
deleteMovieHandler :: MovieId -> Handler NoContent
|
||||
deleteMovieHandler _ =
|
||||
-- delete the movie from the database...
|
||||
pure NoContent
|
||||
|
||||
```
|
||||
|
||||
And assemble them together with the record structure, which is the glue here.
|
||||
|
||||
```haskell
|
||||
server :: ServerT MovieCatalogAPI Handler
|
||||
server =
|
||||
API
|
||||
{ version = versionHandler
|
||||
, movies = moviesHandler
|
||||
}
|
||||
|
||||
moviesHandler :: MoviesAPI (AsServerT Handler)
|
||||
moviesHandler =
|
||||
MoviesAPI
|
||||
{ list = movieListHandler
|
||||
, movie = movieHandler
|
||||
}
|
||||
|
||||
movieHandler :: MovieId -> MovieAPI (AsServerT Handler)
|
||||
movieHandler movieId = MovieAPI
|
||||
{ get = getMovieHandler movieId
|
||||
, update = updateMovieHandler movieId
|
||||
, delete = deleteMovieHandler movieId
|
||||
}
|
||||
```
|
||||
As you might have noticed, we build our handlers out of the same record types we used to define our API: `MoviesAPI` and `MovieAPI`. What kind of magic is this ?
|
||||
|
||||
Remember the `mode` type parameter we saw earlier? Since we need to transform our API type into a _server_, we need to provide a server `mode`, which is `AsServerT Handler` here.
|
||||
|
||||
Finally, we can run the server and connect the API routes to the handlers as usual:
|
||||
|
||||
``` haskell
|
||||
api :: Proxy MovieCatalogAPI
|
||||
api = Proxy
|
||||
|
||||
main :: IO ()
|
||||
main = run 8081 app
|
||||
|
||||
app :: Application
|
||||
app = serve api server
|
||||
|
||||
```
|
||||
Yay! That’s done and we’ve got our server!
|
||||
|
||||
## The Client
|
||||
|
||||
The client, so to speak, is very easy to implement:
|
||||
|
||||
``` haskell
|
||||
movieCatalogClient :: API (AsClientT ClientM)
|
||||
movieCatalogClient = client api -- remember: api: Proxy MovieCatalogAPI
|
||||
```
|
||||
|
||||
Have you noticed the `mode` `AsClient ClientM`?
|
||||
|
||||
We’ve also introduced some operators that help navigate through the nested records.
|
||||
|
||||
`(//)` is used to jump from one record to another.
|
||||
`(/:)` is used to provide a parameter, whether it be a query param or a capture.
|
||||
|
||||
Let’s use those nice helpers for our movie catalog:
|
||||
|
||||
```haskell
|
||||
listMovies :: Maybe SortBy -> ClientM [Movie]
|
||||
listMovies sortBy = movieCatalogClient // movies // list /: sortBy
|
||||
|
||||
getMovie :: MovieId -> ClientM (Maybe Movie)
|
||||
getMovie movieId = movieCatalogClient // movies // movie /: movieId // get
|
||||
|
||||
updateMovie :: MovieId -> Movie -> ClientM NoContent
|
||||
updateMovie movieId newMovie = movieCatalogClient // movies // movie /: movieId // update /: newMovie
|
||||
|
||||
deleteMovie :: MovieId -> ClientM NoContent
|
||||
deleteMovie movieId = movieCatalogClient // movies // movie /: movieId // delete
|
||||
```
|
||||

## Conclusion
|
||||
|
||||
We hope that you found this workbook helpful, and that you now feel more confident using the `NamedRoutes` technique.
|
||||
|
||||
If you are interested in further understanding the built-in Servant combinators, see [Structuring APIs](https://docs.servant.dev/en/stable/cookbook/structuring-apis/StructuringApis.html).
|
||||
|
||||
Since `NamedRoutes` is based on the Generic mechanism, you might want to have a look at [Sandy Maguire’s _Thinking with Types_ book](https://doku.pub/download/sandy-maguire-thinking-with-typesz-liborgpdf-4lo5ne7kdj0x).

Note for Ubuntu users
|
||||
--------
|
||||
|
||||
Ubuntu's packages for `ghc`, `cabal`, and `stack` are years out of date.
|
||||
If the instructions above fail for you,
|
||||
try replacing the Ubuntu packages with up-to-date versions.
|
||||
First remove the installed versions:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
# remove the obsolete versions
|
||||
$ sudo apt remove ghc haskell-stack cabal-install
|
||||
|
||||
Then install fresh versions of the Haskell toolchain
|
||||
using the `ghcup <https://www.haskell.org/ghcup/install/>`_ installer.
|
||||
|
||||
As of February 2022, one easy way to do this is by running a bootstrap script:
|
||||
|
||||
.. code-block:: bash
|
||||
|
||||
$ curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | sh
|
||||
|
||||
The script is interactive and will prompt you for details about what
|
||||
you want installed and where. To install manually,
|
||||
see `the detailed instructions <https://www.haskell.org/ghcup/install/#manual-install>`_.
