MongoDB is a widely used database. In a project, we used Feathers-Mongoose, an Object Document Mapper (ODM) for MongoDB. In the second quarter of 2018, MongoDB added support for database transactions. However, this new feature could not be leveraged using Feathers-Mongoose. So, we made the necessary code changes and raised a Pull Request. After a review process, it was accepted and merged to the codebase. It was later released as v7.1.0.
