How can i catch an fs.readFileSync error if a requested file is not available on sd-card? Right now i get the same result for an empty file and if the file is not available.

You can't at the moment - the best you could do is require("fs").readdir().indexOf("foo")>=0

Perhaps it should return undefined rather than an empty string if the file doesn't exist?

I would prefer to get a 'undefined' instead of an empty string. This way its easier and cleaner to decide if the operation was successful and what actions to take. e.g. send 200 vs. 404.

fs.readFileSync in v1.51 now returns undefined if the file is not found. Thanks a lot Gordon.
