I am trying to replicate the guide Example: image transformation.
I'm ok until I need to call:
import * as gcs from '@google-cloud/storage';
import * as functions from 'firebase-functions';
export const onFileChange = functions.storage.object().onFinalize(object => {
// this line throws a TypeScript Error
const destBucket = gcs.bucket(fileBucket);
...
}
Property 'bucket' does not exist on type 'typeof Storage'. Did you mean 'Bucket'?
I also tried:
const destBucket = new gcs.Bucket(new gcs.Storage({}), object.bucket);
this compiles but when executing I get an error:
gcs.Storage is not a constructor
It seems as if the API has changed, but I'm updated to the latest versions:
"@google-cloud/storage": "^1.6.0",
"firebase-functions": "^1.0.2",
How can I get a reference to the Bucket so that I can call?:
destBucket
.file(filePath)
.download({ destination: tempFilePath })
.then(() => { ... })
Have you declared gcs with a config object like:
const config = {
projectId: '....',
keyFilename: './.......-adminsdk-0vlsn-34c393497c.json'
};
const storage = require('@google-cloud/storage')(config);
You have to use a service-key.json generated in Firebase, as explained in this Cloud Functions official sample https://github.com/firebase/functions-samples/tree/master/generate-thumbnail
"Go to the Firebase Console, select the gear image > project settings > Service Accounts and click Generate New Private Key to download a Service Account Key JSON document."
In addition the error message most probably means that you have to create an instance of Storage.
