I'm going off track here but Pulumi have a totally mind-bending feature where you can write the code of a lambda function not only inline, but such that it captures the value of variables from the surrounding infra code at the time the function is serialized.
Seeing the specific examples they use it for (AWS infra glue) makes me think that there is room for infrastructure related lambdas to be defined right in cfn or infra code, with very low ceremony, even if you wouldn't want to deploy "applications" like that.
I'm working with what I think is a similar problem-space, trying to create a Node.js program that produces code to be run on the browser. The code runs in Node.js at "build time" which essentially means constructing the static web-site, which means some JavaScript must be somehow "deployed" to the website to be then later run at "run time".
So deploying to an AWS etc. Lambda seems conceptually similar to deploying from static-site-generator to a static web-site source-code, which is then what the browser will execute. Or is it?
