I've updated the PR so that it's possible to express a function that would work both in a SSR and WASM context (via FormatterFunction::new_no_args/new_with_args) that wraps the js_sys::Function type. Hopefully this is not too repetitive.

This doesn't seem to compile on wasm because the js_sys::Function type doesn't implement Serialize. I realized you forgot to add #[serde(with = "serde_wasm_bindgen::preserve")] to the js_sys function in the latest force commit

Also, its probably worth adding this from impl:

#[cfg(target_arch = "wasm32")]
impl From<web_sys::js_sys::Function> for FormatterFunction {
    fn from(f: web_sys::js_sys::Function) -> Self {
        FormatterFunction { value: f }
    }
}

@sangelxyz you are using this PR in a leptos project, right? So you are able to use this in a wasm context?

Yes commit 67 does work.

I uploaded a leptos SSR example here.

you can see it in use

You do need a feature tag in order for it to compile in an ssr/wasm context..

@sangelxyz i took a look at your repo, and the charming dependency is specified as a path. I'm thinking your local repo is not up to date with this PR. Are you able to share the FormatterFunction struct definition in your local charming clone here just to clarify it's the same with the latest in this PR
