API
Entry
miso :: Eq model => (URI -> App model action) -> JSM () Source #
Runs an isomorphic miso application.
Assumes the pre-rendered DOM is already present.
Note: Uses mountPoint as the Component name.
Always mounts to <body>. Copies page into the virtual DOM.
startApp :: Eq model => App model action -> JSM () Source #
Runs a miso application
Initializes application at mountPoint (defaults to <body> when Nothing)
Sink
withSink :: (Sink action -> JSM ()) -> Effect model action Source #
sink allows users to access the sink of the Component or top-level
App in their application. This is useful for introducing IO into the system.
A use-case is scheduling an IO computation which creates a 3rd-party JS
widget which has an associated callback. The callback can then call the sink
to turn events into actions. To do this without accessing a sink requires
going via a Subscription
update FetchJSON = withSink $ \sink -> getJSON (sink . ReceivedJSON) (sink . HandleError)
type Sink action = action -> JSM () Source #
Function to asynchronously dispatch actions to the update function.
Sampling
sample :: Component model action -> JSM model Source #
Read-only access to another Component's model.
This function is safe to use when a child Component wishes access
a parent Components model state. Under this circumstance the parent
will always be mounted and available.
Otherwise, if a sibling or parent Component's model state is attempted
to be accessed. Then we throw a NotMountedException, in the case the
Component being accessed is not available.
Message Passing
notify :: Component model action -> action -> JSM () Source #
Used for bidirectional communication between components.
Specify the mounted Component's App you'd like to target.
This function is used to send messages to Components on other parts of the application
Subscription
type SubName = MisoString Source #
SubName
The name of a Sub (e.g. "websocket")
Effect
issue :: action -> Effect model action Source #
A synonym for tell, specialized to Effect
update :: Action -> Effect Model Action update = \case Click -> issue HelloWorld
Used to issue new action
Since: 1.9.0.0
batch :: [JSM action] -> Effect model action Source #
Smart constructor for an Effect with multiple actions.
io :: JSM () -> Effect model action Source #
Like io_ but doesn't cause an action to be dispatched to
the update function.
This is handy for scheduling IO computations where you don't care
about their results or when they complete.
component :: MisoString -> App model action -> Component model action Source #
Smart constructor for Component construction.
Needed when calling embed and embedWith
component_ :: App model action -> Component model action Source #
Smart constructor for Component construction.
This is a nameless component, which means that it is isolated and
cannot be communicated with by other components via notify or sample.
defaultApp :: model -> (action -> Effect model action) -> (model -> View action) -> App model action Source #
Smart constructor for App with sane defaults.
embed :: Eq model => Component model action -> [Attribute b] -> View b Source #
Used in the view function to embed Components in App
embedKeyed :: Eq model => Component model action -> [Attribute b] -> Key -> View b Source #
Used in the view function to embed Components in App, with Key
getMountPoint :: Maybe MisoString -> MisoString Source #
Convenience for extracting mount point
data App model action Source #

data Attribute action Source #
Attribute of a vnode in a View.
The Sink callback can be used to dispatch actions which are fed back to
the update function. This is especially useful for event handlers
like the onclick attribute. The second argument represents the
vnode the attribute is attached to.

A unique key for a dom node.
This key is only used to speed up diffing the children of a DOM node, the actual content is not important. The keys of the children of a given DOM node must be unique. Failure to satisfy this invariant gives undefined behavior at runtime.

Effect
(#>) :: JSM action -> model -> Effect model action infixr 0 Source #
Effect smart constructor, flipped
(<#) :: model -> JSM action -> Effect model action infixl 0 Source #
Smart constructor for an Effect with exactly one action.
batch :: [JSM action] -> Effect model action Source #
Smart constructor for an Effect with multiple actions.
io :: JSM () -> Effect model action Source #
Like io_ but doesn't cause an action to be dispatched to
the update function.
This is handy for scheduling IO computations where you don't care
about their results or when they complete.
issue :: action -> Effect model action Source #
A synonym for tell, specialized to Effect
update :: Action -> Effect Model Action update = \case Click -> issue HelloWorld
Used to issue new action
Since: 1.9.0.0
runEffect :: Effect model action -> MisoString -> model -> (model, [Sink action -> JSM ()]) Source #
Internal function used to unwrap an EffectCore
scheduleIOFor_ :: Foldable f => JSM (f action) -> Effect model action Source #
Deprecated: Please use for instead
scheduleSub :: (Sink action -> JSM ()) -> Effect model action Source #
Deprecated: Please use withSink instead
withSink :: (Sink action -> JSM ()) -> Effect model action Source #
sink allows users to access the sink of the Component or top-level
App in their application. This is useful for introducing IO into the system.
A use-case is scheduling an IO computation which creates a 3rd-party JS
widget which has an associated callback. The callback can then call the sink
to turn events into actions. To do this without accessing a sink requires
going via a Subscription
update FetchJSON = withSink $ \sink -> getJSON (sink . ReceivedJSON) (sink . HandleError)
type Effect model action = EffectCore model action () Source #
A monad for succinctly expressing model transitions in the update function.
Effect is a RWS, where the State abstracts over manually passing the model
around. It's also a Writer Monad, where the accumulator is a list of scheduled
IO actions. Multiple actions can be scheduled using Control.Monad.Writer.Class.tell
from the mtl library and a single action can be scheduled using scheduleIO.
An Effect represents the results of an update action.
It consists of the updated model and a list of subscriptions. Each Sub is
run in a new thread so there is no risk of accidentally blocking the
application.
Tip: use the Effect monad in combination with the stateful
lens
operators (all operators ending in "="). The following example assumes
the lenses field1, counter and field2 are in scope and that the
LambdaCase language extension is enabled:
myApp = App
{ update = \case
MyAction1 -> do
field1 .= value1
counter += 1
MyAction2 -> do
field2 %= f
scheduleIO $ do
putStrLn "Hello"
putStrLn "World!"
, ...
}

Exception
exception :: SomeException -> JSM JSVal Source #
Exception handler
Used to catch Component mounting exceptions
action `catch` exception
data MisoException Source #
The MisoException type is used to catch Component-related mounting errors.
The two mounting errors that can occur during the lifetime of a miso application are
- Not Mounted Exception
This occurs if a user tries to call sample myComponent when myComponent is currently
not mounted on the DOM.
- Already Mounted Exception
It is a requirement that all Component be named uniquely
(this is to avoid runaway recursion during mounting).
If we detect a Component is attempting to be mounted twice
this exception will be raised.
Other exceptions can arise, but its up to the user to handle them in
the update function. All unhandled exceptions are caught in the event loop
and logged to the console with console.error()

Code corresponding to a closed connection https://developer.mozilla.org/en-US/docs/Web/API/CloseEvent
Constructors
| CLOSE_NORMAL | 1000, Normal closure; the connection successfully completed whatever purpose for which it was created. |
| CLOSE_GOING_AWAY | 1001, The endpoint is going away, either because of a server failure or because the browser is navigating away from the page that opened the connection. |
| CLOSE_PROTOCOL_ERROR | 1002, The endpoint is terminating the connection due to a protocol error. |
| CLOSE_UNSUPPORTED | 1003, The connection is being terminated because the endpoint received data of a type it cannot accept (for example, a textonly endpoint received binary data). |
| CLOSE_NO_STATUS | 1005, Reserved. Indicates that no status code was provided even though one was expected. |
| CLOSE_ABNORMAL | 1006, Reserved. Used to indicate that a connection was closed abnormally (that is, with no close frame being sent) when a status code is expected. |
| Unsupported_Data | 1007, The endpoint is terminating the connection because a message was received that contained inconsistent data (e.g., nonUTF8 data within a text message). |
| Policy_Violation | 1008, The endpoint is terminating the connection because it received a message that violates its policy. This is a generic status code, used when codes 1003 and 1009 are not suitable. |
| CLOSE_TOO_LARGE | 1009, The endpoint is terminating the connection because a data frame was received that is too large. |
| Missing_Extension | 1010, The client is terminating the connection because it expected the server to negotiate one or more extension, but the server didn't. |
| Internal_Error | 1011, The server is terminating the connection because it encountered an unexpected condition that prevented it from fulfilling the request. |
| Service_Restart | 1012, The server is terminating the connection because it is restarting. |
| Try_Again_Later | 1013, The server is terminating the connection due to a temporary condition, e.g. it is overloaded and is casting off some of its clients. |
| TLS_Handshake | 1015, Reserved. Indicates that the connection was closed due to a failure to perform a TLS handshake (e.g., the server certificate can't be verified). |
| OtherCode Int | OtherCode that is reserved and not in the range 0999 |
