+# Datadog support for Lambda Web Adapter
+
+This folder contains examples using Lambda Web Adapter and Datadog instrumentation in nodejs (expressjs) using a zipfile and layers instead of a container.
+
+The examples use aws cdk to deploy and curl to test, so make sure they are installed.
+
+# How to use
+
+Instructions are for expressjs
+
+## Install dependencies
+
+Install aws cdk dependencies
+
+```sh
+cd expressjs/cdk
+npm i
+cd -
+```
+
+## Deploy and Run
+
+Deploy with
+
+```sh
+cd expressjs/cdk
+cdk deploy
+cd -
+```
+
+After confirming the deployment, a log will show a public Lambda URL to invoke the endpoint with
+
+```sh
+Outputs:
+lwa-stack.LambdaFunctionUrl = https://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.lambda-url.us-east-1.on.aws/
+```
+
+and the function can be invoked with (note the call_lwa at the end of the URL)
+
+```sh
+curl https://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.lambda-url.us-east-1.on.aws/call_lwa
+```
+
+NB
+this deployment will create a publicly accessible URL link with no security restriction and usage limits! Make sure to run
+
+```sh
+cd expressjs/cdk
+cdk destroy
+cd -
+```
+
+after the example test is done

+# Welcome to your CDK TypeScript project
+
+This is a blank project for CDK development with TypeScript.
+
+The `cdk.json` file tells the CDK Toolkit how to execute your app.
+
+## Useful commands
+
+* `npm run build`   compile typescript to js
+* `npm run watch`   watch for changes and compile
+* `npm run test`    perform the jest unit tests
+* `npx cdk deploy`  deploy this stack to your default AWS account/region
+* `npx cdk diff`    compare deployed stack with current state
+* `npx cdk synth`   emits the synthesized CloudFormation template
