Hi,

I looked at the documentation and typings in the code on my Uppy instance but I’m unable to find something telling me “an upload is ongoing”.

My use case is I want to prevent submitting a form (or leaving the page) while some uploads are still ongoing.

A workaround would be to list all files and try to see for each:

- `isPaused` is true OR if `progress.percentage === 100`

But it seems a bit hacky, no?

Thank you,

---

Hi. I think you can use the `upload` event [Uppy — Uppy](https://uppy.io/docs/uppy/#upload) to set your bool to true

then `complete` [Uppy — Uppy](https://uppy.io/docs/uppy/#complete) to set the bool to false again

Sounds like a good idea @mifi , a bit surprized there is no simple boolean for this but I’m fine with your solution 🙂

I tried to implement it but it seems I have a weird behavior for events with React: [Uppy + Transloadit immediately triggers "complete" event but no upload · Issue #4130 · transloadit/uppy · GitHub](https://github.com/transloadit/uppy/issues/4130#issuecomment-1437198535)
