Demystify the DX for Lambda functions

You can use AWS Cloud Development Kit (CDK) along with your favorite IDEs like Visual Studio Code or IntelliJ to develop a serverless workload using Lambda functions.

AWS Cloud Development Kit (CDK) is an infrastructure as code tool offered by AWS that allows you to write code in your favorite language. It generates a CloudFormation template for the deployment and provisioning of your code and infrastructure.

You can test your Lambda functions locally using AWS SAM (Serverless Application Model). You can use the command 'SAM local start API' to start a local API for testing.

Using ESBuild with AWS CDK helps to make your bundle size smaller. It allows bundling with configurations that support ESM modules and top-level await.

The 'cdk deploy' command deploys your AWS CDK application to an AWS account. It checks your infrastructure and code changes and updates the deployment accordingly.

You can speed up the deployment process using the 'cdk deploy --watch' command along with the 'hotswap' flag. This allows you to swap your code underneath the Lambda function without passing through CloudFormation, making the feedback loop faster.

AWS Lambda Power Tools is an open-source tool that helps operationalize the observability of your applications by adding tracing, metrics, and logs.

You can visualize your AWS CDK infrastructure using AWS Application Composer. It generates a visual representation of your deployed infrastructure from the CloudFormation template.

Amazon CodeWhisperer is a tool integrated with AWS Toolkit that uses generative AI to assist in creating code based on comments you provide.

Amazon Q is a tool that allows developers to ask questions about their code and receive suggestions for improvements. It can provide explanations, optimizations, and code snippets to enhance code performance.
