Add support to specify initial message about yew HOT 2 CLOSED

Thank you for your feedback! ❤️

Your question is simple and hard simultaneously. Simple, because you can use many approaches to implementa that. Hard, because I don't know which is better to choose, but I will try to offer some.

At first, you can use Model with multiple states and initialize it on user action:

enum Model {
    Uninitialized,
    Initialized(Data),
}

fn update(_: &mut Context, model: &mut Model, msg: Msg) {
    match msg {
        Msg::Ready => {
            let data = Data { };
            *model = Model::Initialized(data);
        }
    }
}

The second approach I've demonstrated in the fresh PR #73. Send messages as many as you want directly to App instance. Source: https://github.com/DenisKolodin/yew/blob/ecc34b9b9944cea9627a2e9a3f5a9f7412064ca5/examples/crm/src/main.rs#L211

I also fixed some bugs to make it possible. Now I initialize stdweb when App::new called and you can use AppSender before App::run calling:

fn main() {
    let mut app = App::new();
    let mut context = Context {
        storage: StorageService::new(Scope::Local),
        dialog: DialogService,
    };
    let database = load_database(&mut context);
    let scene = Scene::Initialization;
    let model = Model { database, scene };
    app.sender().send(Msg::SwitchTo(Scene::ClientsList));
    app.run(context, model, update, view);
}

It's also possible to call Context's services as well.

Awesome,

I think app.sender().send() will do the trick.

Thank you!
