Download with SAS token from front end

[QuadmanSWE]

Rather than the backend downloading the file and then streaming it to the front end it could be preferable to download directly from the client using a SAS token that the backend generates.

I can get started on building this if you want.

We don't really need it to work from the front end, we are imagining we will either build our own fork of it or reuse a previous plugin we have. But we were interested in the blob storage interactions of your plugin.

Here is what it looks like when I tried my link generation out in your front end plugin. What do you think?

Here is my branch on it: https://github.com/QuadmanSWE/deepan10-backstage-plugins/tree/directDownloadFromAzure
I rebased off of your new release and made a new branch that I connected on the PR. Linked below...

Awesome 🚀 It's a nice idea to use the SAS token and download it from the Azure Storage account itself. We can remove the Backend download and use the Direct Azure download. Please feel free to raise a PR will ship this out 👍.

It only works if the backend is allowed to generate the sas token though, and the function from microsoft only works if the credentials are of the correct type.

I will need some help with code review to make sure that the changes I am proposing works as intended.

I will still create the PR but I will ping you there so that we can review together when you have the time. Im in CET timezone.
