[bug] Failed to pass an enum as argument in command

[amrbashir]

sounds like an issue in your frontend code, what is the value of projectInfo.value in your frontend code?
it should look something like this:

{
  name: "Project name",
  template: "rustBinary"
}

if it doesn't look like this, then your frontend is the issue, otherwise please provide a minimal repro and ping me

It's something like this:

enum Template {
  RustBinary,
  RustLibrary,
  ...
}

const projectInfo: ComputedRef<ProjectInfo> = computed(() => {
  const template =
    Template[projectTemplateInput.value as keyof typeof Template];
  return {
    name: projectName.value, // string
    template, // Template
  });

Typescript enums are not 1:1 equivalent of Rust enums, so you have to make sure they are equal, there is two ways you can do this:

1. use repr(u16) but will require usage of serde_repr crate so serialization/deserialization could work properly, see https://serde.rs/enum-number.html
2. change the typescript enum definition to match the serialization of rust enum, so it would look like this:

   enum Template {
     RustBinary = "rustBinary",
     RustLibrary = "rustLibrary",
     ...
   }

I have fixed it through the first way.
But I think this is really confusing for tauri user, maybe Tauri should provide a macro like #[derive(tauri::CommandArg)] to do these works(derive Serialize_repr, Deserialize_repr or Serialize, Deserialize traits, and add #[serde(rename_all = "camelCase")]) on-demand?

I think you're looking for https://github.com/oscartbeaumont/tauri-specta which generates typescript definitions for your based on your commands .
