If a field doesn't exist, NEDB will create it automatically (e.g. db.update({'foo.bar': 'value'}) will create a field of "bar" inside "foo").

OK but now my issues is i need to check if the filed exist before reading is there any way since my code stop from there when it's didn't find the field. And thank you very much for quick response

Maybe there is a better way to handle this, but without updating your database, you can provide a default value like let x = db.find({key: value}) || value;

I run into the same problem a lot too so I'm also interested to know if anyone has a better solution.
