Mongo helper methods for working with data in a DAO or repository pattern. As well as some required misc helper methods for interacting with mongo.

DAO/Repository Pattern

The primary purpose of this is to abstract the interaction with the Database. This has the following benefits:

  • Easier to mock and DI throughout the app
  • Doesn't depend so heavily throughout the app on setting up Mockgoose
  • Wraps all response objects in a proper class
  • Avoids the messy nature of Mongoose statics/methods


The pattern requires the following on Mongo objects:

  • There is a createdAt and updatedAt field
  • That _id is auto converted to id when toObject() is called
  • That __v is removed when toObject() is called

To do that, there is a helper method that sets those up. Simply call initMongoCleanAndTimestamp() in the models of the app.


See the sample folder. The file/folder structure and files should be all that you need to get started.
