DynamoDB table scan and display web application

This is a dynamic s3 website which uses API gateway and Lambda to scan a Dynamodb Table and displays in tabular format.

Before deploying the Stack::

Zip up function.js
Create an S3 bucket and upload the function.zip file
Update template.yaml - bucket-name ( in CodeUri)

Deployment using Cloudformation

aws cloudformation deploy --template-file template.yaml --stack-name <<STACK-NAME>>--capabilities CAPABILITY_IAM

Identify "api-gateway-url" from the output

aws cloudformation describe-stacks --stack-name <<STACK-NAME>>  --query Stacks[].Outputs[].OutputValue[] --output text

After deploying the Stack::

 Update the <<api-gateway-url>> in index.html
 Upload to s3 bucket and enable website.

Browse the s3 website.

Javascript within index.html calls the API gateway to read the table and display in the browser. Initally the table is empty. The MySamInsertFunction can be manually invoked used to 'put a sample item' into the DynamoDB table.

Now refresh the browser to display the table contents.

sam-ddb-display's Issues

The template is using unsupported runtime (nodejs6.10)

Error from CloudFormation: The runtime parameter of nodejs6.10 is no longer supported for creating or updating AWS Lambda functions. We recommend you use the new runtime (nodejs12.x) while creating or updating functions.
