Add a TextArea.Model to your model.

type alias MyModel =
    { myTextArea : TextArea.Model
    }

Add a TextArea.Model to your model.

myInitialModel : MyModel
myInitialModel =
    { myTextArea = TextArea.init -- optionally pipe into State Setters
    }

Add a TextArea.Msg to your Msg.

type MyMsg
    = UpdateMyTextArea TextArea.Msg

Use in your update function.

myUpdate : Msg -> Model -> ( Model, Cmd Msg )
myUpdate msg model =
    case msg of
        UpdateMyTextArea inputMsg ->
            { model | myTextArea = TextArea.update inputMsg mode.myTextArea } ! []

Transform an TextArea.Model into an TextArea.View, which allows us to pipe View Setters on it.

myView : Model -> Html Msg
myView model =
    div
        []
        [ TextArea.view model.myTextArea -- pipe view setters here, for example |> setIsLocked 'your logic here'
        ]

Transforms an TextArea.View into Html TextArea.Msg

myView : Model -> Html Msg
myView model =
    div
        []
        [ TextArea.view model.myTextArea
            |> TextArea.render
            |> Html.map UpdateMyTextArea
        ]
