AWS Elastic Beanstalk Express Sample App with Dynamo

This sample application uses the Express framework and Bootstrap to build a simple, scalable customer signup form that is deployed to AWS Elastic Beanstalk. The application stores data in Amazon DynamoDB and publishes notifications to the Amazon Simple Notification Service (SNS) when a customer fills out the form.

This example cannot be run locally.

You can get started using the following steps:

  1. Install the AWS Elastic Beanstalk Command Line Interface (CLI).
  2. Add policies to the default instance profile to grant the EC2 instances in your environment permission to access DynamoDB and Amazon SNS:
    • Open the Roles page in the IAM console.
    • Choose aws-elasticbeanstalk-ec2-role.
    • On the Permissions tab, choose Attach policies.
    • Select the managed policy for the additional services that your application uses. For this specific example, add AmazonSNSFullAccess and AmazonDynamoDBFullAccess.
    • Choose Attach policy.
  3. Run eb init --platform node.js --region <region> to initialize the folder for use with the CLI. Replace <region> with a region identifier such as us-east-2 (see Regions and Endpoints for a full list of region identifiers).
  4. Run eb create --sample nodejs-example-express-dynamo to begin the creation of a sample application that contains a load-balanced environment with the default settings for the Node.js platform.
  5. Once the environment creation process completes, run eb open to load the sample environment in your browser to verify the deployment has succeeded and is accessible.
  6. Deploy the source in this bundle using eb deploy.
  7. Once the deployment of this source bundle completes, run eb open to interact with the new webpage.
  8. Run eb terminate --all to clean up.


The code includes several Bootstrap themes from You can dynamically change the active theme by setting the THEME environment variable in the Elastic Beanstalk Management Console:
