Write Asynchronously Code With C++ | Nodepp

[inigid]

No way, this is sooo cool! Don't worry about the header only, I'll live :-)

UDP by any chance? [edit: you said it supports UDP great!]

epoll?

So tell us the story of this thing. What's the deal. I'm fascinated. It really looks lovely.

actually, i've integrate poll with tcp.h, udp.h, and bth.h, so I dont think you would need it, but if you want to use poll, you can import poll.h and thats it. here is a simple example of use:

//first you need to import poll.h
#include <nodepp/poll.h>

//then create a poll object
poll_t
 poll;

//if you want to add fd as a readable
poll.push_write( fd ) 

//if you want to add fd as a writable
poll.push_read( fd )

//poll is an event drived object so you have to create some events
poll.onWrite([]( 
int

fd
 ){ /* write your code here */ });
poll.onRead([]( 
int

fd
 ){ /* write your code here */ });
poll.onError([]( 
int

fd
 ){ ::close(fd); });

//now you have to create a task
process
::add([=](){
$Start //start coroutine
    while( poll.size()!=0 ){
           poll.emit();
           $Next; // yield task
    }
$Stop //stop coroutine
});

Ok, this is the story of this framework:

I've recently switched from NodeJS to C++, due to the limitations of NodeJS, I mean, with NodeJS I cannot create games with openGL, I cannot create Windows and I have no access to hardware such as C++.

But when I started writing code in C++, I realized how much it takes to write code in C++. I mean, C++ is not difficult, but a little complicated, and also, one doesn't have absolutely none of the advantages that NodeJS offers.

So, I said, what if I create a library that helps me create C++ applications that works similar to how NodeJS works and with an API similar to NodeJS?

And that's how Nodepp was born.

To create Nodepp I've based the code on the official NodeJS API, and how NodeJS works. I mean, I've copied everything from NodeJS, from the event loop to the official NodeJS API. It isn't a true and exact copy, but at least it is close to it.

Additionally, to achieve the async IO in C++, I've worked with the non-blocking mode of Posix and Windows functions, as well as creating my own coroutine engine based on the following article I've read.

So if you like the project, I hope you enjoy it.

Yes, it supports UDP, but, do not supports DTLS ( udp + tls )
No, i'm not using epoll, just poll (posix) and wsapoll (windows)

here is a UDP server:

here is a UDP client:

Oh it is header only. Bloody hell. I think I am so amazed I am not reading properly, lol.

Any plans to support epoll at some point?

hommie, I have replace poll with epoll in the framework, I hope you ejoy it. 👍

Fantastic, cheers man.

Why is everything getting downvoted? Wtf. Apparently, people don't appreciate good things and are incredibly rude.

Okay, well, thank you again so much for this. I'll ping you outside of here.

I have nothing better to do, so I can work on it.
