Websocket to POSIX proxy

[Harsh chopra]

Hi,

I am trying to generate POSIX sockets proxying in "js" ,  use it in Browser and make it act as a server.

The program under "tools/websocket_to_posix_proxy/" use CMake which works perfect when build with "cmake && make" but when I used "emcamke cmake" , it generate Makefile using "node" as the cross_compiler which is fine but when I use "emmake make" it wont build because "node" dont support posix socket.

So is there any other way things could work?

----------CMAKELIST.TXT------------------

 cmake_minimum_required(VERSION 2.8)
project(websocket_to_posix_proxy)
file(GLOB sourceFiles src/*.cpp src/*.h)
add_executable(websocket_to_posix_proxy ${sourceFiles})
find_package(Threads)
target_link_libraries(websocket_to_posix_proxy ${CMAKE_THREAD_LIBS_INIT})

if (WIN32)
    add_definitions(-D_CRT_SECURE_NO_WARNINGS)
    add_definitions(/wd4200) # "nonstandard extension used: zero-sized array in struct/union"
    target_link_libraries(websocket_to_posix_proxy Ws2_32.lib)
endif()

I believe the websocket_to_posix_proxy is designed to run natively on the server, so you want to build with regular `cmake` and not `emcake`.    It doesn't run in JS or compile with emscripten.

I build a simple posix socket server to listen on localhost and convert the program with emcc to make it compatible on browser(Firefox) but nothing worked,  I tried everything upto my potential and I am really confused now.

According to https://emscripten.org/docs/porting/networking.html

Under title - "Full Proxy Sockets over WebSocket Proxy Server"

I believe it's telling us how to allows full POSIX Sockets API access from a web browser.

But I am not able to figure out how.

Please help, guidance required.

Yes, I have tried tcp_echo_client.cpp and it works perfectly with "tools/websocket_to_posix_proxy/" .

Other examples look like client programs
