Nodepp-WASM

Nodepp is a groundbreaking open-source project that simplifies C++ application development by bridging the gap between the language's raw power and the developer-friendly abstractions of Node.js. By providing a high-level API, Nodepp empowers developers to write C++ code in a familiar, Node.js-inspired style.

One of the standout features of Nodepp is its 100% asynchronous architecture, powered by an internal Event Loop. This design efficiently manages Nodepp’s tasks, enabling you to develop scalable and concurrent applications with minimal code. Experience the power and flexibility of Nodepp as you streamline your development process and create robust applications effortlessly!

Examples

Hello world

#include <nodepp/nodepp.h>

using namespace nodepp;

void onMain() {
    console::log("Hello World!");
}

// note that we are using onMain() instead of main()

HTTP Client

#include <nodepp/nodepp.h>
#include <nodepp/fetch.h>

using namespace nodepp;

void onMain() {

    fetch_t args;
            args.url = "https://localhost:8000/";

    fetch::add( args )

    .then([=]( fetch_t res ){
        console::log( "->", res.status );
        console::log( res.headers["Content-Length"] );
    })

    .fail([=]( except_t rej ){
        console::log( rej );
    });

}

Websocket Client

#include <nodepp/nodepp.h>
#include <nodepp/ws.h>

using namespace nodepp;

void onMain() {

    auto srv = ws::connect( "wss://localhost:8000" );
    
    srv.onConnect([=]( ws_t cli ){

        cli.onData([]( string_t data ){
            console::log( data );
        });

        cli.onClose([](){
            console::log( "done" );
        });

    });
