Multi-document Atomicity in Mongoose (MongoDB)

A short example to show how to use MongoDB's v4.x multi-document transactions in mongoose.

This was adopted from the official MongoDB example here but instead of the native mongo client we use mongoose.

Setup

Follow the instructions in the "Set Up" section here. Then in your shell:

yarn
DB_URI='your_mongo_atlas_uri' node init
DB_URI='your_mongo_atlas_uri' node transactions
