dynamodb-streams

This example reimplements AWS developer guide tutorial (Process New Items with DynamoDB Streams and Lambda) with slight modification through Serverless Framework.

Source

Deployment

First, clone the project to local:

> git clone [email protected]:m-sureshraj/serverless-examples.git
> cd dynamodb-streams 

Configure environment variables:

> cp .env.sample.yml .env.dev.yml

Add your email address to the EMAIL_SUBSCRIBER: [email protected] variable.

> sls deploy

A successful deployment print a similar output:

✔ Service deployed to stack dynamodb-streams-dev (163s)

endpoint: POST - https://xxxxxxx.execute-api.ap-south-1.amazonaws.com/
functions:
  bark: dynamodb-streams-dev-bark (46 kB)
  dbChangeListener: dynamodb-streams-dev-dbChangeListener (46 kB)

After successful deployment, SNS sends a subscription confirmation email to the configured email address. Click confirm subscription link to subscribe to that topic.

Testing

Get the endpoint from the sls deploy output and send a POST request to it.

curl -X POST https://xxxxxxx.execute-api.ap-south-1.amazonaws.com/ \
-H 'Content-Type: application/json' -d '{ "username": "bar" }'

You should receive the notification email to the configured email address.
