Help: Running from a firebase cloud function

[Toolenaar]

Hi I would like to run this from a firebase cloud function (node), where it fetches an audiofile from a storage bucket and generates the waveform data. But I have no clue where to start, would this even be possible ? Can anyone nudge me into the right direction? Any help is really appriciated

I don't know anything about Firebase, but the general steps would be:

1. Install audiowaveform (e.g, as described in https://github.com/bbc/audiowaveform#installation). If this is anything like AWS Lambda, though, you'll need to compile and upload a statically linked build of audiowaveform suitable for whatever OS Firebase uses, together with your Node.js code
2. Write a Node script to fetch the audio file, run it through audiowaveform, then store the waveform data somewhere, presumably to another storage bucket

@Toolenaar Have you had any success with this? I'm looking into doing something similar.

From what I can tell, Firebase Functions have a defined set of system packages that will be installed, that can't be changed: https://cloud.google.com/functions/docs/reference/system-packages

I'm thinking of setting up a micro service with the more flexible Cloud Run, which could have access to storage / be called from a function: https://cloud.google.com/workflows/docs/run/tutorial-cloud-run
