digitalmars.D - Nginx to D ?

Hello,

I am not really confident on this one, but could D be interfaced 
with Nginx ?

It would be nice to replace python but if not easily doable, then 
it is a no-no for me.

Any clue on it ?

Thanks

Sure you can. There are three options:
1. Make nginx act as a reverse proxy forwardind all traffic to some 
socket. You can use vibe.d this way
2. Make a D fastcgi process and point nginx to it. There is Adam 
Ruppe's cgi.d implementation for example.
3. Write an extension for nginx and use its internal api. Nginx is 
written in C and D can easily interface with C

Yeah, my cgi.d can interface with nginx through fastcgi, scgi, or 
reverse proxy pretty well.

Though my code doesn't scale as well as vibe.d, it is fairly 
simple to use and isn't particularly slow (vibed wins because it 
scales well and is fast more than because my code is slow :P )

If you're interested, here's the file:
https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff/blob/master/cgi.d

my github also has other miscellaneous D modules for things like 
png images, mysql database access, html dom manipulation, and 
more. Not super well documented but if you have questions feel 
free to ask here or on the chat and I can answer them.


But if you are going for high load, probably best to try 
http://vibed.org/ as it scales better and they offer async libs 
for database and stuff too.

Let me add a bit more of context : I currently use UWSGI but I 
would like to accelerate python replacing it with D.

Less memory consumption and so on..

I need something as robust as uwsgi.

If there is none, then, no go. :)

Thanks !

you want http://vibed.org/
the same as in the tutorial links i posted.

Now, the next question : are those implementations robust ?

Do they bite (are they reliable )?
Do many people use it ?

Remember, I am coming from python where everything is easy and am 
already learning D and decided to give it a jump.

Probably only current information about vibe.d performance is 
this article : 
https://atilanevesoncode.wordpress.com/2013/12/05/go-vs-d-vs-erlang-vs-c-in-real-life-mqtt-broker-implementation-shootout/

I have been doing some basic benchmarking ~year ago but I have 
removed those because vibe.d has changed too much since then and 
I have no infrastructure to reproduce them right now. But 
comparing to Python performance are likely to skyrocket even it 
has become twice slower since then (it was faster then CPython + 
Tornado more than 10x)

Reliability is still an issue but it is being worked on as one of 
priorities. Both vibe.d own website and forum run this very 
software so it is at least that reliable.

Well it is relatively new, and not many people know about D and fewer
about Vibe.d. If you use it others will think it is more commonly
used :-)

Being one of the pioneers won't make me cry.

I had a look at it. This project seems like it deserves a bit
more work :

http://forum.rejectedsoftware.com/groups/rejectedsoftware.vibed/thread/7556/

This is particularly annoying and a show stopper for me.

I will definitely look for its evolution though..


I think D is a good language, pretty easy to work with, without
all the cryptic of c++, and really well performing when compiled
with the right options.

To me, it is another world from python.

But when I look at UWSGI, it is directly tied to nginx so no need
to manage yet another server and so on. It just works as is,
redirects to the app and boom, executes the script.

I don't think I want another server behind nginx. But I will lose
the async capability..

tough..

There is no practical difference - uWSGI has own protocol, 
reverse proxy mode uses HTTP for it. But usage remains pretty 
similar - you just run the app and redirect requests to it, 
that's all. With added benefit that it is still a 100% feature 
complete and capable application even without any kind of 
application server or reverse proxy.

You don't necessarily need nginx, vibe.d is quite capable to act 
as only server. It is recommended to put it behind nginx to 
reduce possible security concerns and because nginx has a lot 
more options to configure HTTP behavior.

Not many, as not many people use D in general. No negative 
feedback from those who have tried so far though ;) You may want 
to contact developer(s) directly via 
http://forum.rejectedsoftware.com/groups/rejectedsoftware.vibed/ 
for any detailed information.
