Emscripten builds to single file, no need for http server, no browser security restrictions

[Pe3ucTop]

Version/Branch of Dear ImGui:

Version: any , Branch: any

Back-ends:

• imgui_impl_glfw.cpp + imgui_impl_opengl3.cpp
• imgui_impl_glfw.cpp + imgui_impl_wgpu.cpp ( with examples/libs/emscripten/shell_minimal.html modifications )

Compiler, OS:

Linux + Emscripten

Full config/build information:

No response

Details:

Suggestion for builds with Emscripten to use Makefile linker flag: LDFLAGS += -sSINGLE_FILE which will result in single html file output (EXE = $(WEB_DIR)/index.html).

Goals of single output file:

• no need for http server, file could be opened directly by Web browser;
• no Web browser security restrictions for hardware use requests (serial port in my condition and should be the same for gamepad / usb / audio / camera / etc );
• easy to redistribute.

Negative aspect:

• output file is bigger then sum of all files of split build because of included binary files got converted to BASE64 format.

You are free to build your app however you like. I don’t think there is value in us providing example apps that use this build method.
