Summary
In this chapter, we discussed how to streamline serverless development by using a local express server and LocalStack for a local cloud environment. We provided step-by-step instructions for installing and running LocalStack and cdklocal
, configuring the DynamoDB endpoint to point to LocalStack, and importing the same function used in the deployed Lambda function to the local server. Additionally, we showed how to run commands and make requests to the local development server to test the code’s functionality. The overall objective of this process is to enable the local testing and development of AWS cloud infrastructure without incurring costs or impacting production resources. In the next chapter, we will introduce the concept of indestructible serverless application architecture (ISAA), a design pattern for building serverless applications that are highly resilient and can scale infinitely.
