In this workshop you will create a CRUD API that Creates, Reads, Updates and Deletes items from a DynamoDB table. The API will run serverless, so there is no management of the underlying infrastructure and scaling is done automatically. You will learn how easy it is to create an API on AWS with AWS CDK, all within 60 minutes. The workshop features the creation of a DynamoDB table, HTTP API Gateway and a Lambda function. This workshop is based on https://catalog.us-east-1.prod.workshops.aws/workshops/2c8321cb-812c-45a9-927d-206eea3a500f/en-US. But has been pimped so you can do the same but with AWS CDK code.

1. Build your first CRUD
API in 60 minutes or
less with AWS CDK!
