You can use one lambda to handle multiple API gateway requests. Route to ANY. Then have a bridge that connects to your favorite language router. We do this all the time with NestJS. The down side is you burn some cash when someone calls a 404 resource since your NestJS has to say that it’s missing and that requires at least 100ms of lambda time. You could probably get around this by generating a route maker off the NestJS controller files.
