What libraries are people using to run webservers other than

I think for D to a have good web story it needs to appeal to
serious backend developers, not hipsters who go after fads
(mongodb is a fad, jade/haml is a fad).
I probably need to combine several libraries, but the features
I'm looking for are:
- Spawn an HTTP server listening on a port, and routing
requests to functions/delegates, without hiding the details of
the http request/response objects (headers, cookies, etc).
- Support for websockets
- Runs delegates in fibers/coroutines
- Basic database connectivity (No "orm" needed; just raw sql).
- When iterating the result set of a sql query, has the ability
to automatically map each row against a struct, and throw if
the structure does not match.
- More generally, map any arbitrary object (such as json) to a
struct. Something like Zewo/Reflection package for swift[0].

I feel like Vibe.d satisfies my first 3 requirements, but for
the rest I will probably have to look for something else.

Don't use these components :-)

Vibe.d does this - just don't use the automatic API generation
feature if you don't like it. Note, you can get access to the
request/response objects even if you do use the API generation by
using an @before method. E.g. in an interface you may have
something like this:
@method(HTTPMethod.POST)
@before!getRequestInfo("requestInfo")
@property Token login(LoginRequestMeta login, RequestInfo
requestInfo);
And then define your getRequestInfo method like this:
static RequestInfo getRequestInfo(HTTPServerRequest req,
HTTPServerResponse res)
{
RequestInfo requestInfo;
requestInfo.headers = req.headers;
requestInfo.ipAddress = req.clientAddress.toAddressString();
requestInfo.userAgent = requestInfo.headers.get("User-Agent",
"");
return requestInfo;
}
In this case I've grabbed the ip address and user agent of the
user, but you could also grab cookies etc.

You can do this with MySQL Native whilst using vibe.d. You might
do something like this:
Prepared prepared = prepare(this.conn, sql);
prepared.setArgs(params);
auto row = prepared.queryRow();
if (row.isNull()) {
throw new Exception("Query returned an empty row");
}
T item;
try {
row.toStruct!T(item);
} catch(Exception e) {
}
Where T is your struct type that you're trying to convert the row
to.
As for the template language, you could try:

There are probably others.
