Can I write files in companion app

[olegl84]

Is there a possibility in companion app to write files ?
I need to create intermediate buffer before sending data to API.   Of course, I can use localStorage, but I need "append" behavior. Do not want to use memory while getting and setting values in localStorage.

Unfortunately not. It's only localStorage or settingsStorage on the phone side.

Is it still not possible to write a file on companion side of app?

No. In addition to what Jon said, you can use fetch() or WebSocket to send data to a server, which could be an app running on the same device as the companion and which saves the data to a file.
