Datadog support for Lambda Web Adapter

This folder contains examples using Lambda Web Adapter and Datadog instrumentation, in nodejs (expressjs) and python (flask).

The examples use aws cdk to deploy and curl to test, so make sure they are installed.

How to use

Instructions are for expressjs, similarly use the flask folder for the python example

Install dependencies

cd expressjs/cdk
npm i
cd -

Install Datadog dependencies

cd expressjs/lambda-asset/src
npm i

Deploy and Run

Deploy with

cd expressjs/cdk
cdk deploy
cd -

After confirming the deployment, a log will show a public Lambda URL to invoke the endpoint with

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)

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

cd expressjs/cdk
cdk destroy
cd -

after the example test is done
