equivalent to `/`, but sometimes it just lets you chain another combinator.
Tip: If your endpoint responds to `/` (the root path), just omit any combinators
that introduce path segments. E.g. the following api has only one endpoint on `/`:
``` haskell
type RootEndpoint =
Get '[JSON] User
```
We can also describe APIs with multiple endpoints by using the `:<|>`
combinators. Here's an example:

@ -151,21 +151,120 @@ so we need a `Proxy` for our API type `API'` without its `Raw` endpoint.
Very similarly to how one can derive haskell functions, we can derive the
javascript with just a simple function call to `jsForAPI` from
`Servant.JQuery`.
`Servant.JS`.
``` haskell
apiJS :: Text
apiJS = jsForAPI api vanillaJS
apiJS1 :: Text
apiJS1 = jsForAPI api jquery
```
This `Text` contains 2 Javascript functions, 'getPoint' and 'getBooks':
``` javascript
var getPoint = function(onSuccess, onError)
{
$.ajax(
{ url: '/point'
, success: onSuccess
, error: onError
, type: 'GET'
});
}
var getBooks = function(q, onSuccess, onError)
{
$.ajax(
{ url: '/books' + '?q=' + encodeURIComponent(q)
, success: onSuccess
, error: onError
, type: 'GET'
});
}
```
We created a directory `static` that contains two static files: `index.html`,
which is the entrypoint to our little web application; and `ui.js`, which
contains some hand-written javascript. This javascript code assumes the two
generated functions `getPoint` and `getBooks` in scope. Therefore we need to
write the generated javascript into a file:
``` haskell
writeJSFiles :: IO ()
writeJSFiles = do
T.writeFile "static/api.js" apiJS1
jq <- T.readFile =<< Language.Javascript.JQuery.file
T.writeFile "static/jq.js" jq
```
(We're also writing the jquery library into a file, as it's also used by
`ui.js`.) `static/api.js` will be included in `index.html` and the two
generated functions will therefore be available in `ui.js`.
And we're good to go. You can start the `main` function of this file and go to
`http://localhost:8000/`. Start typing in the name of one of the authors in our
database or part of a book title, and check out how long it takes to
approximate pi using the method mentioned above.
## Customizations
Instead of calling `jquery`, you can call its variant `jqueryWith`.
Here are the type definitions
```haskell ignore
jquery :: JavaScriptGenerator
jqueryWith :: CommonGeneratorOptions -> JavaScriptGenerator
```
The `CommonGeneratorOptions` will let you define different behaviors to
change how functions are generated. Here is the definition of currently
available options:
```haskell ignore
data CommonGeneratorOptions = CommonGeneratorOptions
{
-- | function generating function names
functionNameBuilder :: FunctionName -> Text
-- | name used when a user want to send the request body (to let you redefine it)
, requestBody :: Text
-- | name of the callback parameter when the request was successful
, successCallback :: Text
-- | name of the callback parameter when the request reported an error
, errorCallback :: Text
-- | namespace on which we define the js function (empty mean local var)
, moduleName :: Text
-- | a prefix that should be prepended to the URL in the generated JS
, urlPrefix :: Text
}
```
This pattern is available with all supported backends, and default values are provided.
## Vanilla support
If you don't use JQuery for your application, you can reduce your
dependencies to simply use the `XMLHttpRequest` object from the standard API.
Use the same code as before but simply replace the previous `apiJS` with
the following one:
``` haskell
apiJS2 :: Text
apiJS2 = jsForAPI api vanillaJS
```
The rest is *completely* unchanged.
The output file is a bit different, but it has the same parameters,
``` javascript
var getPoint = function(onSuccess, onError)
{
var xhr = new XMLHttpRequest();
xhr.open('GET', '/point', true);
xhr.setRequestHeader("Accept","application/json");
xhr.setRequestHeader(\"Accept\",\"application/json\");
xhr.onreadystatechange = function (e) {
if (xhr.readyState == 4) {
if (xhr.status == 204 || xhr.status == 205) {

We created a directory `static` that contains two static files: `index.html`,
which is the entrypoint to our little web application; and `ui.js`, which
contains some hand-written javascript. This javascript code assumes the two
generated functions `getPoint` and `getBooks` in scope. Therefore we need to
write the generated javascript into a file:
And that's all, your web service can of course be accessible from those
two clients at the same time!
## Axios support
### Simple usage
If you use Axios library for your application, we support that too!
Use the same code as before but simply replace the previous `apiJS` with
the following one:
``` haskell
writeJSFiles :: IO ()
writeJSFiles = do
T.writeFile "static/api.js" apiJS
jq <- T.readFile =<< Language.Javascript.JQuery.file
T.writeFile "static/jq.js" jq
apiJS3 :: Text
apiJS3 = jsForAPI api $ axios defAxiosOptions
```
(We're also writing the jquery library into a file, as it's also used by
`ui.js`.) `static/api.js` will be included in `index.html` and the two
generated functions will therefore be available in `ui.js`.
The rest is *completely* unchanged.
The output file is a bit different,
``` javascript
var getPoint = function()
{
return axios({ url: '/point'
, method: 'get'
});
}
var getBooks = function(q)
{
return axios({ url: '/books' + '?q=' + encodeURIComponent(q)
, method: 'get'
});
}
```
**Caution:** In order to support the promise style of the API, there are no onSuccess
nor onError callback functions.
### Defining Axios configuration
Axios lets you define a 'configuration' to determine the behavior of the
program when the AJAX request is sent.
We mapped this into a configuration
``` haskell
data AxiosOptions = AxiosOptions
{ -- | indicates whether or not cross-site Access-Control requests
-- should be made using credentials
withCredentials :: !Bool
-- | the name of the cookie to use as a value for xsrf token
, xsrfCookieName :: !(Maybe Text)
-- | the name of the header to use as a value for xsrf token
, xsrfHeaderName :: !(Maybe Text)
}
```
## Angular support
### Simple usage
You can apply the same procedure as with `vanillaJS` and `jquery`, and
generate top level functions.
The difference is that `angular` Generator always takes an argument.
``` haskell
apiJS4 :: Text
apiJS4 = jsForAPI api $ angular defAngularOptions
```
The generated code will be a bit different than previous generators. An extra
argument `$http` will be added to let Angular magical Dependency Injector
operate.
**Caution:** In order to support the promise style of the API, there are no onSuccess
nor onError callback functions.
``` javascript
var getPoint = function($http)
{
return $http(
{ url: '/point'
, method: 'GET'
});
}
var getBooks = function($http, q)
{
return $http(
{ url: '/books' + '?q=' + encodeURIComponent(q)
, method: 'GET'
});
}
```
You can then build your controllers easily
``` javascript
app.controller("MyController", function($http) {
this.getPoint = getPoint($http)
.success(/* Do something */)
.error(/* Report error */);
this.getPoint = getBooks($http, q)
.success(/* Do something */)
.error(/* Report error */);
});
```
### Service generator
You can also generate automatically a service to wrap the whole API as
a single Angular service:
``` javascript
app.service('MyService', function($http) {
return ({
postCounter: function()
{
return $http(
{ url: '/counter'
, method: 'POST'
});
},
getCounter: function()
{
return $http(
{ url: '/books' + '?q=' + encodeURIComponent(q), true);
, method: 'GET'
});
}
});
});
```
To do so, you just have to use an alternate generator.
``` haskell
apiJS5 :: Text
apiJS5 = jsForAPI api $ angularService defAngularOptions
```
Again, it is possible to customize some portions with the options.
``` haskell
data AngularOptions = AngularOptions
{ -- | When generating code with wrapInService, name of the service to generate, default is 'app'
serviceName :: Text
, -- | beginning of the service definition
prologue :: Text -> Text -> Text
, -- | end of the service definition
epilogue :: Text
}
```
# Custom function name builder
Servant comes with three name builders included:
- camelCase (the default)
- concatCase
- snakeCase
Keeping the JQuery as an example, let's see the impact:
``` haskell
apiJS6 :: Text
apiJS6 = jsForAPI api $ jqueryWith defCommonGeneratorOptions { functionNameBuilder= snakeCase }
```
This `Text` contains 2 Javascript functions:
``` javascript
var get_point = function(onSuccess, onError)
{
$.ajax(
{ url: '/point'
, success: onSuccess
, error: onError
, type: 'GET'
});
}
var get_books = function(q, onSuccess, onError)
{
$.ajax(
{ url: '/books' + '?q=' + encodeURIComponent(q)
, success: onSuccess
, error: onError
, type: 'GET'
});
}
```
And we're good to go. You can start the `main` function of this file and go to
`http://localhost:8000/`. Start typing in the name of one of the authors in our
database or part of a book title, and check out how long it takes to
approximate pi using the method mentioned above.

-- Maintainer : Alp Mestanogullari <alpmestan@gmail.com>
-- Stability : experimental
-- Portability : portable
--
-- Automatically derive a mock webserver that implements some API type,
-- just from the said API type's definition.
--
-- Using this module couldn't be simpler. Given some API type, like:
--
-- > type API = "user" :> Get '[JSON] User
--
-- that describes your web application, all you have to do is define
-- a 'Proxy' to it:
--
-- > myAPI :: Proxy API
-- > myAPI = Proxy
--
-- and call 'mock', which has the following type:
--
-- @
-- 'mock' :: 'HasMock' api context => 'Proxy' api -> 'Proxy' context -> 'Server' api
-- @
--
-- What this says is, given some API type @api@ that it knows it can
-- "mock", 'mock' hands you an implementation of the API type. It does so
-- by having each request handler generate a random value of the
-- appropriate type (@User@ in our case). All you need for this to work is
-- to provide 'Arbitrary' instances for the data types returned as response
-- bodies, hence appearing next to 'Delete', 'Get', 'Patch', 'Post' and 'Put'.
--
-- To put this all to work and run the mock server, just call 'serve' on the
-- result of 'mock' to get an 'Application' that you can then run with warp.
--
-- @
-- main :: IO ()
-- main = Network.Wai.Handler.Warp.run 8080 $
-- 'serve' myAPI ('mock' myAPI Proxy)
