Listen in typescript and call from rust

[night galleon]

Is it possible to listen to a event from rust in typescript ? I know i can invoke rust code from typescript but how can i do the reverse. I didn't find anything useful. Basically when i open the window from rust i want to call that function and focus the input box. Simple as that

but how do i call it on the rust side?

using vue it crashes xd

and i cant even see the log lmao

i have this:

const focusInput = await listen<string>("focus", (event) => {
  console.log("Entrou no input")
})

[junior solar]

what crashed? backend or only frontend?

[night galleon]

frontend i think

main_window.emit("focus", "").unwrap();

[junior solar]

so window still exists?

[night galleon]

hm maybe i should unhide to debug this. it starts hidden by default

stays on the tray

[junior solar]

or listen after unhide

3 days on the same app has been killing me lmao

cant even do simple things

@proud latch @visual grotto have you ever needed to do this? The only place that its not crashing is onMounted but then it's not listenting. The console.log won't trigger

and the window crashes otherwise

[visual grotto]

Had to do what, listening in the frontend then emitting events from the Rust side?

[night galleon]

yeah

Kinda like this?

  async mounted() {
    const self = this
    self.unlisten = await listen('system_state_update', (event) => {
      self.systemState = event.payload
    })
    await invoke('setup')
  }

dont know what i did but it worked this time

lmao

[visual grotto]

Always love when that happens x)

[night galleon]

i think i know why

i created a const with a ref this time

instead of creating it onmount

probably that was it
