How to do it...

1. Let's look at an example. Suppose we're deleting a file; let's now see how we can formulate our error messages based on the error type:

       //Deleting an image from the bucket.        imageRef.getMetadata()          .then((meta) => {       //Meta function parameter represent our file metadata.                console.log(meta);            })            .catch(err => {                  switch (err.code) {                       case 'storage/unknown':                        break;                       case 'storage/object_not_found':                       breaks;                       case : 'storage/project_not_found':                       breaks;                       case : 'storage/unauthenticated':                       breaks;                       case : 'storage/unauthorized':                       breaks;                       ..                       ...                       ....                  }            });

2. Switching over the err.code type, we'll get a string that represents the error type we're facing. Then we can provide the proper showcasing of the error, with the help of which we can have ...
