Networking

Before starting

• Investigate POCO libraries and find a workaround for "not detected compiler features" in emscripten

If POCO is not an option, then

Rely on SDL2_NET with TCP and implement websocket entrypoint (or use websocketify)
A nice wrapper can be used too https://github.com/mwthinker/Network

Interesting resources for SDL_net

• TCP: https://www.stephenmeier.net/2015/12/23/sdl-2-0-tutorial-04-networking/
• UDP: http://headerphile.com/sdl2/sdl2-part-12-multiplayer/

Update:

• The last version of POCO isn't trivial to compile in emscripten. ticket here
• SDL2_net isn't detected by emscripten (there is no SDL_net.h in emscripten includes even tho it appears listed when running emcc --show-ports). Waiting for this ticket

Next steps:

• Try using an older version of POCO that supports WebSockets

• Investigate if adding SDL_net.h manually works

  Adding SDL_net.h manually works well, this might be a way of doing this.
  Problem: SDL2_net doesn't have any websocket layer, so I might need to build it by myself for the server :(

This topic is also being discussed in Corrade repository as it maybe makes sense to create a simple socket abstraction there
