alternative to #16590
fixes #11879
This PR makes the assumption that a catch-all serverless function is deployed with no routes in its manifest (the alternative was an explicit flag). It then exports a helper which should be called in such a serverless function after
server.respondso that it can invoke the correct handler instead of simply returning a 404 since it has no route information in its SSR manifest.The advantage of this approach compared to deploying a middleware that only runs reroute is that it's simpler implementation-wise and it allows the user's
handleFetch,inithooks, etc. to run correctly without any additional effort from us.The disadvantages are that:
reroutewill run twice: once in the catch-all function then again in the correct function. We could choose to skip the secondreroutebased on someheadervalue or context (if any) that can be passed between serverless functions. Otherwise, I chose to omit this so that thereroutehook can't be skipped from outside influence (someone setting the header themselves without runningreroutefirst)reroute. Not that big of an issue I think...Please don't delete this checklist! Before submitting the PR, please make sure you do the following:
