Is it possible to use a callback in a JSON type?

[irakliasatiani]

There are many components in react that are using callback functions inside objects, it seems it's not working with web component JSON format, which is in fact expectable since it's just text, and it can't understand what is the function in the JSON. but would be really nice if we could use function as a object param like this.

    <web-app
      obj-prop='{ "very": "object", "such": "wow!", "callback": "myFunction:function"}'
    >
    </web-app>

is there any other way other than using the function param only as top level param?

I think what you want to achieve is communication between web components or with a web component. I would use something like Custom Event or Broadcast Channel to communicate inside/outside the component, just like what you would do with iframes.

https://wataruoguchi.github.io/poc-spa-gh-pages/ uses runneljs, a Broadcast Channel based library, to demonstrate that the two web components are communicating each other by displaying "Total Count". I hope it's helpful.

I think they need to parse json object in the same way they're parsing the parameters. So, any function prop inside json will be parsed and mapped correctly.

Also, they can do a better job in how defining R2WCOptions<HeaderProps> to not need to pass string values for property types. So: instead of onClick: 'function' we will have onClick: WcTypes.Function.
