Formatter::Function does not work on WASM backend

[v3xro]

You can create e.g. an AxisLabel with Formatter::Function in WASM, but it will be rendered as a string with the RAW_MARK prefix/suffix #*#*#*# and will not be available to call from JS. Unsure how to get it to work presently.

Do you have an example of how to use this in wasm ?

[v3xro]

Yes, currently it would look like:

Formatter::Function(js_sys::Function::new_with_args(
                        "arg1, arg2, arg3",
                        r#"return arg1 + arg2 + arg3;"#,
                    ))

However I noticed that my PR does not make the code compatible with non-wasm targets. I think you could probably provide a From<(String, String)> on both WASM and SSR targets, the former calling js_sys::Function::new_with_args and the latter printing out the function definition fully e.g. format!("function ({args}) { {body} }", ..). I might update the PR with that as it seems a simple enough workaround for the types needing (necessarily) to be different.

Nice, thank you. I'll keep an eye on the update. I'm only using wasm with a leptos project.

Hi, is there any updates on this? Currently I don't think I can provide my own function for this

You can try out the PR referenced above. But this is not yet fixed/implemented on main.

I'm using the PR in a leptos project, it's working great.

Can you provide a small example? And do you know if the formatter functions work with ssr? If you don't know, I will check it myself.

sure, i'll make a simple SSR example and post tomorrow.

formatter functions work with ssr

it will fail without a feature flag.
