I don't mean remove a document or documents. I mean remove the model entirely so that mongoose is no longer aware of it. After declaring a model I can't figure out how to make mongoose forget that model so that it could be recreated.
mongoose.model('Book', bookSchema);
mongoose.model('Book', bookSchema);
Currently the above throws an exception.
OverwriteModelError: Cannot overwrite 'Book' model once compiled.
I'd like to be able do something like this...
mongoose.model('Book', bookSchema);
mongoose.removeModel('Book');
mongoose.model('Book', bookSchema);
...and not get any errors. Any ideas?

Mongoose | remove() Function The remove() function is used to remove the documents from the database according to the condition.
There is currently no method called deleteById() in mongoose. However, there is the deleteOne() method with takes a parameter, filter , which indicates which document to delete. Simply pass the _id as the filter and the document will be deleted.
Mongoose | findOneAndDelete() FunctionThe findOneAndDelete() function is used to find a matching document, remove it, and passes the found document (if any) to the callback. Installation of mongoose module: You can visit the link to Install mongoose module. You can install this package by using this command.
try this
delete mongoose.connection.models['Book'];
and then re-register/re-initialize it . it will work fine
