Firebase Storage-How to delete file from storage with node.js? - node.js

Question

I want to delete a folder in firebase storage with node js because this is a firebase function.
For example :
storageRef.child(child1).child(child2).delete();
something like this, but firebase documentation doesn't tell anything.
One more question:
When initialize storage documentation node js requires my admin json, but realtime database doesn't want this wonder why?

Answer 1

Have a look at the Node.js client API Reference for Google Cloud Storage and in particular at the delete() method for a File.

Answer 2

You can do it like this using Node.js:
const firebase = require('firebase-admin');
async function deleteImageFromFirebase(imageName) {
await firebase.storage().bucket().file("folderName/"+imageName).delete();
}
And like this client side:
// Create a reference to the file to delete
var desertRef = storageRef.child('images/desert.jpg');
// Delete the file
desertRef.delete().then(function() {
// File deleted successfully
}).catch(function(error) {
// Uh-oh, an error occurred!
});

Answer 3

This might be late but at least on Web (so basically what you need), there is new API to delete the whole folder.
I tested deleting a folder with 2 pictures inside and it works. I then tried a folder-A with contents: folder-B + picture-A. Folder-B also has a picture-B inside; it still deleted folder-A with all of its contents.
Solution:
const bucket = admin.storage().bucket();
return bucket.deleteFiles({
prefix: `posts/${postId}`
);
I couldn't find this on the official documentation (perhaps is really new API) but really cool article where I found the solution:
Automatically delete your Firebase Storage Files from Firestore with Cloud Functions for Firebase

import { storage } from "./firebaseClient";
import { bucket } from "./firebaseServer";
//Let's assume this is the URL of the image we want to delete
const downloadUrl = "https://storage.googleapis.com/storage/v1/b/<projectID>.appspot.com/o/<location>?"
//firebase delete function
const deleteImages = async ({ downloadUrl }) => {
const httpsRef = storage.refFromURL(downloadUrl).fullPath;
return await bucket
.file(httpsRef)
.delete()
.then(() => "success")
.catch(() => "error")
}
//call the deleteImages inside async function
const deleteStatus = await deleteImages({ downloadUrl: oldImage });
console.log(deleteStatus) //=> "success"
