Trilateral API Expanded

This example includes several Lambda functions, a Kinesis stream and an API Gateway

This example builds on the implementation of the Trilateral API presented in Cloud Native Development Patterns and Best Practices

Steps

1. Execute: npm install
2. Execute: npm run dp:dev:e
3. In the AWS console review the various tabs for the following:
   • Cloudformation Stack: cndp-trilateral-api-dev
   • Lambda functions: cndp-trilateral-api-dev-*
   • API Gateway: cndp-trilateral-api
4. Invoke POST api from the API Gateway console by pressing the Invoke URL link:
   • APIs > dev-cndp-trilateral-api (...) > Stages > dev > /things > POST
5. Inspect the DynamoDB dev-cndp-trilateral-api-t1 table for the new contents
   • Copy an id for step 6
   • Verify that none of the records are flagged as deleted
6. Inspect the Lambda Monitoring tab and logs for function: cndp-trilateral-api-dev-publish
7. Invoke GET api from the API Gateway console by pressing the Invoke URL link:
   • APIs > dev-cndp-trilateral-api (...) > Stages > dev > /things/{id} > GET
8. Inspect the Lambda Monitoring tab and logs for function: cndp-trilateral-api-dev-query
9. Invoke Lambda function cndp-trilateral-api-dev-produce-category-deleted from the AWS console by pressing the Test button
   • Accept the defaults if asked.
10. Inspect the Lambda Monitoring tab and logs for function: cndp-trilateral-api-dev-subscribe
11. Inspect the DynamoDB dev-cndp-trilateral-api-t1 table for the new updates
    • Verify that the records with the "widgets" category are flagged as deleted
12. Execute: npm run rm:dev:e
