Question

I’m preparing a database creation script in Node.js and Mongoose.
How can I check if the database already exists, and if so, drop (delete) it using Mongoose?

I could not find a way to drop it with Mongoose.

Answer 1

There is no method for dropping a collection from mongoose, the best you can do is remove the content of one :

Model.remove({}, function(err) { 
   console.log('collection removed') 
});

But there is a way to access the mongodb native javascript driver, which can be used for this

mongoose.connection.collections['collectionName'].drop( function(err) {
    console.log('collection dropped');
});

Warning

Make a backup before trying this in case anything goes wrong!
