Amazon DynamoDB and AngularJS

Question

So, I created an AWS dynamoDB table (database) and I am ready to get that data with AngularJS. How do I do this with AngularJS? Do I need to setup another service with Amazon? O

Answer 1

Yes, you can access Amazon DynamoDB directly from your AngularJS application using the AWS JavaScript SDK for the Browser. The same code snippet should work for NodeJS as well.

One thing to note is that your application needs to securely authenticate to AWS without embedding security credentials in the code. Amazon Cognito makes it easy and automatically takes care of authentication if you have created an identity pool and configure your application accordingly. Here are some links that will help you get started. We built a demo application with AngularJS on Amazon DynamoDB. It uses Amazon Cognito for authentication and the Document SDK to store and retrieve JSON objects to and from DynamoDB directly, without needing to serialize and deserialize them in client code in the browser.
