# Cmd.Extra

Experimental package with helpful functions for working with Cmd.

This package can help you with construction of `Cmd msg` and composition of pair `(model, Cmd msg)` that can be used to streamline your flow of actions in `update`.

```elm

    type Msg

        = NoOp

        | Disarm

        | Fire

        | FireRockets

    update : Msg -> Model -> ( Model, Cmd Msg )

    update msg model =

        case msg of

            DoNothing ->

                Cmd.Extra.pure model

                -- equivalent of (model, Cmd.none)

            Disarm ->

                Cmd.Extra.withTrigger NoOp model

                -- equivalent of (model, Cmd.Extra.perform NoOp)

            Fire ->

                ( model, Cmd.Extra.perform FireRockets )

            FireRockets ->

                Rockets.Nukes.fire

```
