Stackery CRUD Demo - NodeJS 8.10

This is a sample template for a serverless AWS Lambda application, written in JavaScript.

The application implements a CRUD interface in front of an AWS DynamoDB table that manages a simple user record. An API Gateway distributes requests to the various AWS Lambda functions based on their HTTP paths and methods.

The application architecture is defined in template.yaml, a Serverless Application Model (SAM) template which can be managed through the Stackery UI at app.stackery.io.

Clone this stack in Stackery, deploy it, and test as follows:

  • Set STAGE_LOCATION from the deployed Rest Api resource properties.

  • Create a user:

      curl --header "Content-Type: application/json" \
      --request POST \
      --data '{"id": "unique001", "firstName": "Alice", "lastName": "Smith", "color": "blue"}' \
      ${STAGE_LOCATION}/users
    
  • List users:

      curl ${STAGE_LOCATION}/users
    
  • Read a user:

      curl ${STAGE_LOCATION}/users/unique001
    
  • Update a user:

      curl --header "Content-Type: application/json" \
      --request PUT \
      --data '{"firstName": "Alice", "lastName": "Smith", "color": "green"}' \
      ${STAGE_LOCATION}/users/unique001
    
  • Delete a user:

      curl --request DELETE ${STAGE_LOCATION}/users/unique001
    
You can’t perform that action at this time.
