If you target WebGL2 you can likely do it without hand modifying the shaders. In a small test I did I just patched the emscripten library_gl.js to do a very simple search and replace of the version string of shaders and stuff just worked. code: https://github.com/greggman/doodles/tree/master/glfw-imgui https://github.com/greggman/doodles/tree/master/glfw-imgui demo: https://greggman.github.io/doodles/glfw-imgui/out/glfw-imgui.html https://greggman.github.io/doodles/glfw-imgui/out/glfw-imgui... You do have to decide if you want to restructure you code to be event based or if you want it leave it as is and set emscripten to generate really slow code for your main loop https://kripken.github.io/emscripten-site/docs/porting/emterpreter.html#emterpreter-async-run-synchronous-code https://kripken.github.io/emscripten-site/docs/porting/emter...
