Announcing a helper library to support using structs instead of bare maps while using the MongoDB-Driver:

Hex.pm
Github
Demo

Features:

• automatic load and dump function
• reflection functions
• type specification
• support for embedding one and many structs
• support for after load function
• support for before dump function
• support for id generation
• support for default values
• support for derived values

The module creates some boilerplate code, so you can use structs for your data. You call load/1 to convert the map from the driver to your struct. To save your struct to MongoDB you call dump/1 before you call insert_one or insert_many.

Check out the docs!

mongox - DEPRECATED
mongo - 0.5.4 December 1, 2015 (docs)
mongodb_erlang - seems not to support op_msg (since 3.6)

Unfortunately, the libraries are not up-to-date regarding the MongoDB server. Since I use the latest version of my projects and therefore want to use the features of the server, I was looking for a suitable driver. Unfortunately I did not find one, so I searched for the best starting point and developed my own driver.
