Dynamo Entity Manager

A entity manager for AWS Dynamo. It's a class that tracks some entities loaded from dynamo data base (or created to be persisted in that data base), and that when flushing, it persist the state change in that data base.

Use cases:

• Helps managing the persistence with the Dynamo API.
• Helps when you want to persist all the changes at once. Ideally the persist should be transactional, but Dynamo does not allow it. You have te take care of making the services as small as posible, and managing possible persisting errors.

Prerequisites

Requires aws-sdk package (if executed in AWS Lambda, it is already installed). For transactional flush, aws-sdk should be included in your lambda, as installed in cloud is an old version.

npm install --save-dev aws-sdk

npm scripts

Build the js files from typescript:

npm run build

Running tests:

npm run test

Running style check:

npm run style
