I am using 
https://dlang.org/spec/expression.html#import_expressions for 
text files. Don't know if it works on binary files as well.

It works on anything since it just loads in the data (as text I 
think?) from the file. But you can just convert it to a buffer 
etc.

And this works than good together with the vibe framework? So, it's not 
requiring or forcing one to use files or databases?

vibe.d uses this for their templates.

For a VFS you would need to have your own API (can be library) that you 
explicitly use.

Haven't tested it, but something like this:

---
import vibe.core.core : runApplication;
import vibe.http.server;

void handleRequest(scope HTTPServerRequest req, scope 
HTTPServerResponse res)
{
	if (req.path == "/file.txt")
		res.writeBody(import("file.txt"), "text/plain");
}

void main()
{
	auto settings = new HTTPServerSettings;
	settings.port = 8080;
	settings.bindAddresses = ["::1", "127.0.0.1"];

	auto l = listenHTTP(settings, &handleRequest);
	scope (exit) l.stopListening();

	runApplication();
}
---

Of course you may want to use the router or the rest generator 
for this. See the examples in the repo.

Doing it like that is kinda pointless though because you can just 
serve static files.
