How to check if fs.read() is empty

Question

I need to check whether a file is empty before I can put it in JSON.parse().

if (fs.exists('path/to/file')) { // true
   return JSON.parse(fs.read('path/to/file'));
}

I know that the file exists by fs.exists(), but how can I check if the file contains no strings before I can put it in JSON.parse()?

JSON.parse(fs.read('path/to/file'));

Returns:

SyntaxError: JSON Parse error: Unexpected EOF

Try this:

if (fs.exists('path/to/file')) {
    if (fs.read('path/to/file').length === 0) {
        //Code to be executed if the file is empty
    } else {
        return JSON.parse(fs.read('path/to/file'));
    }
}
