Hi, i’m attempting to create a single lambda that will serve an express app that renders individual javascript functions. I’m not entirely sure if the approach i’m taking is kosher. Would greatly appreciate any comments/advice! https://github.com/michaelnyu/next-pulumi-test

I’m not sure why you need the express app. I would look into using the AWSX package with the API Gateway. You can make multiple routes including those that serve static content backed by an S3 bucket.
