Basic table storage system

This module provides a DynamoDB table with three predefined policies for read from, write into and administer it. As usual, it can be deployed standalone or as part of a larger setup

Module components

This module contains a DynamoDB table with a partition key, and priced on-demand. Three policies allow specific access levels to that table - i.e. read, write, and admin, respectively. These policies can be attached to the users that will ultimately interact with the table, being able to assign more tailored permissions into their statements.

Default configuration

By default, a table called MyTable will be created, containing a String primary key called Id.

Getting started

Running in one click

I'm working on preparing automated builds of the modules that could be installed in one click. Stay tuned!

Installing from code

Install the dependency: npm i @cdk-modules/ddb-storage or clone this repository. If you just want to install this module standalone, follow this process

cd cdk-modules/ddb-storage/
npm i
npm run build
cdk deploy

And a new stack will appear in your account containing this module's resources.

Integrating it into your app

If you already have a larger CDK app going - or plan to have it - you can use this module to provide your app with the authecation mechanism you'd need. Just install the deependency into your project, and follow this example:

import { DdbStorage } from '@cdk-modules/ddb-storage'

...
this.storage = new DdbStorage(this, 'DdbStorage', {
  tableName: 'MyTable',
  keyName: 'Id'
});
...

Combine modules

Combine with Cognito Auth

This module, in combination with cognito-auth, will allow you to provide table storage to your users. You could use object-level IAM statement conditions to further limit the access to the table items - i.e. by User Id or OAuth sub.
