Firebase: using admin sdk to store images - firebase

Question

I am trying to store images to firebase storage, I am using node.js.
import * as admin from 'firebase-admin';
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: 'https://xxx-app.firebaseio.com',
storageBucket: 'xxxx-app.appspot.com'
});
function storeHeadShots(){
const bucket = admin.storage().bucket();
bucket.upload('./headshots/Acker.W.png', function(err, file){
if (!err){
console.log('file uploaded')
} else {
console.log('error uploading image: ', err)
}
});
}
storeHeadShots();
Now the above works fine, but I have a folder in storage users/ and inside this folder I am storing images. How do I access this folder ?

Answer 1

For anybody who was trying to solve the same problem.
The example is taken from the official documentation here but it doesn't say anything about how to put a file inside a folder. The default example puts the file under the root of the bucket with the same name as the local file.
I had to dig a little deeper into the Cloud Storage class documentation here and I found that for the options a destination parameter exists that describes the file inside the bucket.
In the following example the local file images/bar.png will be uploaded to the default bucket's file /foo/sub/bar.png.
const bucket = admin.storage().bucket();
bucket.upload('images/bar.png', {
destination: 'foo/sub/bar.png',
gzip: true,
metadata: {
cacheControl: 'public, max-age=31536000'
}
}).then(() => {
console.log('file uploaded.');
}).catch(err => {
console.error('ERROR:', err);
});
Hopefully that saved some time for others. Happy uploading!
