Building for WebAssembly

[tupini07]

As the title says, is there any possibility building a project using raylib-zig to wasm ? Any examples of how to accomplish this?

[Not-Nik]

Should be possible, at least with some hacks. Raylib currently uses emscripten for web apps iirc. I'll check on this when I get back from vacation later this week.

I'd also like to know. I would like to try Zig in a gamejam but I think WASM is essential for that.

Any news on this front?

[Not-Nik]

Currently not possible, since raylib's build.zig only offers support for Windows, Linux, macOS and *BSD. I have created an issue on its repository: raysan5/raylib#2884

[Not-Nik]

raylib now has support for building for emscripten since raysan5/raylib#2901 was merged, but Zig can't generate the required extra files that create the required JS functions (for OpenGL etc.) so at least the link step for the final "executable" has to be done with emscripten.

On the Zig side ziglang/zig#10836 tracks this issue.

I was able to get it to work: https://github.com/bluesillybeard/ZigAndRaylibSetup

It's a hassle to set up and it's also pretty janky, but it does work.

Edit: Forgot to mention, I didn't use this wrapper, but instead used Raylib by itself

If you can neatly integrate it into the current build script, don't hesitate to open a PR
