Front end: Is SEO relevant? YES: AWS Lambda generating server rendered HTML behind API Gateway. NO: Vanilla React.JS app hosted on S3

Back End: AWS Lambda behind API Gateway

Database: AWS DynamoDB

Could you elaborate (or link to a framework) for doing the server generated HTML on Lambda?

I mean I'm literally building an AWS lambda function that outputs HTML when it's called via API Gateway. So someone hits https://mydomain.com/mycoolpage, then the MyCoolPage AWS Lambda function is executed, does database queries or reaches out to other lambda functions I've built as microservices and then outputs <html>whatever</html>.

If you're interested, I use https://middy.js.org/ as a middleware engine for my AWS lambda functions which I find helpful.

I use the open sourced serverless framework for doing deploys https://www.serverless.com/ though I'm probably going to move to using AWS SAM in the future.
