mongodbjs vs mongoosejs

the native mongodb driver
performance better than mongoose
no schema fixed, e.g. two product, t-shirt vs digital camera
different kind of products have different property sets, which require flexible document model

higher level interface to MongoDB, it actually uses mongodb.js
fixed schema, like order, account,
coding level, schema can be easily changed
ODM, object document modeling tool
schema&model instantiate the same object whenever you need to create and save something
development faster than mongodbjs

it’s better to use the mongoDB native drivers while still using mongoose for the good stuff.
