Bevy 0.5 doesn't natively support compiling for wasm. You need bevy-webgl for that. The pipelined-renderer branch does support it with the newel renderer that uses the latest wgpu version.

Near-duplicate of #88. :)

@bjorn3 I tried using bevy_webgl2 as well and it did not solve the compilation issue

[bjorn3]

Maybe you need to disable the bevy_wgpu feature of bevy?

[TheButlah]

Sorry, I see what you mean - bevy_webgl2 is intended to be a web friendly alternative for bevy_wgpu. So my issue would be better restated as "I cannot figure out how to use bevy and bevy_webgl2 together on WASM". I can close and reopen a different issue

@TheButlah see https://bevy-cheatbook.github.io/platforms/wasm.html for an excellent guide.
