Upload into specific folder Firebase Storage NodeJS?

Hey I have found out how to upload into the firebase storage:

admin.initializeApp({
  credential: secret,
  databaseURL: secret,
  storageBucket: secret,
});

var bucket = admin.storage().bucket();


const uploadToFireStorage = (filename, query, fileType, imageURL) => {
  bucket.upload(filename).then(console.log("uploaded"));
};

As you can see with my bucket.upload function I can upload to firebase storage but it gets uploaded into the root folder and I want to put it under /foodImages/myfile.png for example Any ideas ?

Answer

Actually Google Cloud Storage does not have genuine “folders”.

In the Cloud Storage console, the files in your bucket are presented in a hierarchical structure of folders (just like the file system on your local hard disk) but this is just a way of presenting the files: there aren’t genuine folders/directories in a bucket. The Cloud Storage console just uses the different parts of the file paths to “simulate” a folder structure, by using the “/” delimiter character.

So, you need to use an UploadOptions object as shown in the doc with a destination property which is defined with some “/”, as follows:

const destinationFilename = "folder1/myfile.png";
bucket.upload('...', { destination: destinationFilename });
