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!

let me say: tempus fugit.

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.

The new version 1.0.0 has been released:

Enhancements:

• add migration (da65de4)
• improve the dump and load functions (#154) (e7f2d44)
• use the same timestamps in new/0 function (0db61da)

Bugfix:

• remove a bug in the hello handshake protocol (thanks to fireproofsocks for reporting) (59aa841)
• remove derived attributes in the dump function (c1b60b4)

Breaking changes - Mongo.Repo and Collections Module

Prior to version 0.9.2 the dump/1 function returns atoms as key. Since the dump/1 function is the inverse function of load/1, which uses binary keys as default, the dump/1 function should return binary keys as well.

Prior to version 0.9.2 some Mongo.Repo functions use the dump/1 function for the query (and update) parameter. This worked only for some query that used only the attributes of the document. In the case of nested documents, it didn’t work, so it is changed to be more consistent. The Mongo.Repo module is very simple without any query rewriting like Ecto does. In the case you want to use the :name option, you need to specify the query and update documents in the Mongo.Repo functions following the specification in the MongoDB.

If you upgrade the driver to version 1.0.0 and you use the collection feature, please check you code!

The new version 0.7.0 has been released:

• support for command monitoring
• support for retryable reads
• support for retryable writes

Enhancements:

• refactored the api of Mongo.limits and Mongo.wire_version
• add support for tracking recovery token from response in a sharded transaction
• new function BSON.ObjectId.decode/1 and BSON.ObjectId.encode/1
• new function Mongo.uuid/1
• refactored event notification system
• refactored the test cases
• now using mtools for a MongoDB deployment in the travis ci environment
• Session.commit_transaction returns now :ok or an error {:error, %Mongo.Error{}}
• support for errorLabels
