How to update App state from JS about seed

[David-OConnor]

Ran into this myself last night while experimenting with fetch - there's no way, and I'd like to add this soon. Currently, all state changes after the initial load are tracked by elements with attached listeners. I'm not sure if the best approach is to somehow expose the app state (eg allow calling vdom::App:update_dom from the API), or exploit the current listener system for events that 'fire instantly'.

The api example you posted is appropriate (eg call something like seed::update_state().

For your specific example, if you only need to process the state on initial load, you may be able to workaround by calling seed::run() inside your then block. eg something like:

#[wasm_bindgen]
pub fn render() {
    my_exported_Js_bridge(payload();
  
}

#[wasm_bindgen]
pub fn my_exported_js_bridge(my_paylod: &str) -> () {
    // create or process model here. 
   let mut model = Model::dafault();
    // ....
    // then:
    seed::run(model, update, view, "main", None);
}

If you need to do this after init load, need to wait for a fix.

Thanks. For init load I actually did something similar as you described, but I will also need this after init load.

Lastest commit has a working soln to this, but it requires a breaking change to the view func (additional param) I'll publish once cleaned up. (see server integration example)

Updated as v0.1.12.

Works great now. Gonna close this.
