how to check if file exists in Firebase Storage?

Question

When using the database you can do snapshot.exists() to check if certain data exists. According to the docs there isn\'t a similar method with storage.

I've found a nice solution while keeping within the Node.js Firebase Gogole Cloud Storage SDK using the File.exists, taught it would be ideal to share for those searching.

const admin = require("firebase-admin");
const bucket = admin.storage().bucket('my-bucket');

const storageFile = bucket.file('path/to/file.txt');
storageFile
  .exists()
  .then(() => {
    console.log("File exists");
  })
  .catch(() => {
    console.log("File doesn't exist");
  });
