Answer 1

This is what I currently use, it's simple and it works flawlessly.

You don't need to do anything with Google Cloud. It works out of the box with Firebase..

// Save the base64 to storage.
const file = admin.storage().bucket('url found on the storage part of firebase').file(`profile_photos/${uid}`);
await file.save(base64Image, {
    metadata: {
      contentType: 'image/jpeg',
    },
    predefinedAcl: 'publicRead'
});
const metaData = await file.getMetadata()
const url = metaData[0].mediaLink

EDIT: Same example, but with upload:

await bucket.upload(fromFilePath, {destination: toFilePath});
file = bucket.file(toFilePath);
metaData = await file.getMetadata()
const trimUrl = metatata[0].mediaLink

#update: no need to make two different call in upload method to get the metadata:

let file = await bucket.upload(fromFilePath, {destination: toFilePath});
const trimUrl = file[0].metatata.mediaLink
