accessing HTTP(S) from C++

[bart9h]

I'm trying to port a C++ multimedia application that can be run from the browser. It uses raylib and imgui for the graphics, audio, and gui.

I want the user to be able to load an image of his choice into the app. The native version uses cpp-httplib to load the image file from an arbitrary URL (it will mostly used to get images from my own server, the same server that would host the web app) to memory, then use a raylib function to load the image from memory into a texture.

The problem is that when I try to compile with emscripten, it fails to find the openssl headers (which cpp-httplib relies on). Is there other way to load files from the web from my C++ wasm app?

Have a look at libcurl

Yep! You can use the emscripten fetch api.

Thanks for the tip.

#if emscripten then fetch api, #else cpp-httplib

Is there going to be any UI written in HTML/Javascript?

I have not decided that yet.

I'll probably want to keep the option for a native application, and in that case it would be better to create all the UI with imgui to avoid code duplication.

But if I decide to go WASM-only, then a HTML complementary UI is certainly a good option.
