vibe.d looks great! Looking through the docs, it feels clean and "hip" like node.js

However, there are a couple refactoring choices I think would have made it even more "hip", consider the home page example:

    import vibe.d;

    void handleRequest(HttpServerRequest req,
                       HttpServerResponse res)
    {
        res.writeBody("Hello, World!", "text/plain");
    }

    static this()
    {
        auto settings = new HttpServerSettings;
        settings.port = 8080;

        listenHttp(settings, &handleRequest);
    }

"vibe.d" as the project name is great, but why have module vibe.d and not simply vibe? Or, why prefix all the types with "HttpServer" when you could separate those objects into a new module and drop the prefix. I think those simple changes would make an already polished library shine a bit brighter:

    import vibe.http;

    void handleRequest(Request req, Response res) {
        res.writeBody("Hellow, World!", "text/plain");
    }

    static this() {
        auto settings = new Settings;
        settings.port = 8080;

        listen(settings, &handleRequest);
    }

the echo server would look like:

    import vibe.tcp;

    static this()
    {
        listen(7, (conn){ conn.write(conn) });
    }

Also, it's great to see MongoDB support built in :D, but isn't there a way to trim down the query object from:

    BSON({"name": BSON("Peter")})

to:

    BSON({"name":"Peter"})

by writing a generic AssosiativeArrayToBSON function? That way you could overload MongoDB's find/save/etc functions to accept arbitrary AAs as queries, which would end up looking a lot slicker in the docs I think. Plus, through CTFE it's possible this conversion could happen at both compile-time and run-time:

    auto db = new MongoDB;
    auto col = db["test.collection"];

    foreach (doc; col.ctFind!(["name":"Peter"])) {

        ...
    }

Just some ideas in case you haven't thought of them already :)


Overall vibe.d looks like a fantastic library. Thank you and Congrats!

More complicated projects/frameworks ontop of vibe which implements it's own main is free to use vibe.all.

But I think...
  import vibe.d;
... makes perfect sense because it contains main()!

It is awesome. I think some part of this could be integrated into phobos after some refactoring. I think about databases for instance, or some http libraries.

This is an ignorant question, but why not the async IO stuff?  It seems like it could be widely useful.  Or is it only designed for this kind of use?

Ah I see, I was thinking the example wasn't the full code. Still, I think doing something like:

    import vibe, vibe.html;

where vibe has main() and vibe.html has html is still better semantics.

This is an ignorant answer, because I didn't looked at the source code, but I guess most of it is highly dependent on vide itself.

Impressive. The website also looks really nice, and it's very fast.

I'll definitely play with it and slowly try to make it into my workplace, hehe.

How did you install it? I can't find the install.sh script anywhere...

How to use it?

Making the installation more automated is planned next, and the install.sh was unfortunately documented before it was written. For now I would recommend to create a symlink to the vibe script in /usr/bin and then create a new project along the lines of the 'first steps' section (http://vibed.org/docs#first-steps). In particular, there should be a source/app.d file.

It's possible that bin directory also needs to be writable because of how rdmd stores its .deps file, which is a bug that will get fixed. Sorry for the slightly bumpy start.
