The documentation referenced by Yamil - Firebase javascript SDK file upload - recommends using the snapshot's ref property to invoke the getDownloadURL method, which returns a promise containing the download link:

Using your code as a starting point:

fileref.put(file)
   .then(snapshot => {
       return snapshot.ref.getDownloadURL();   // Will return a promise with the download link
   })

   .then(downloadURL => {
      console.log(`Successfully uploaded file and got download link - ${downloadURL}`);
      return downloadURL;
   })

   .catch(error => {
      // Use to signal error if something goes wrong.
      console.log(`Failed to upload file and get link - ${error}`);
   });

I know it seems like unnecessary effort and that you should be able to get the link via a property of the snapshot, but this is what the Firebase team recommends - they probably have a good reason for doing it this way.
