将 Firebase 存储文件夹下载到 Cloud Functions 临时文件夹

Question

I'm trying to download the entire folder from Firebase Storage so I can zip those files and upload them back to Firebase Storage while generating a download link.

I have read a lot of posts and code but everything seemed getting away from my scope.

Do you have a clear example on how to download a Firebase Storage Folder to a Cloud Functions Temporary Folder or at least some hints on I could do it, keeping in mind that I am targeting a specific folder?

Answer 1

There is no bulk download operation provided by the SDK. The general pattern for downloading all files with some shared prefix using the node SDK for Cloud Storage will be:

1. list the files using getFiles at the prefix (folder) of interest
2. iterate them
3. download each one separately
