Demo to run Rust code on the browser without javascript. The game I forked is a local multiplayer co-op twin-stick shooter. I did not write any part of it. I simply use it as an example.

Primary LanguageRust

This is a demo to show how to run Rust on the browser without javascript. The game project I use as example is not mine. It comes from here: https://rhmoller.dev/posts/2020/my-experience-with-rust-and-websys/

Build and run

./build.sh
python3 demo_server/server.py

Open http://localhost:8080/

Requirements

  • Rust
  • wasm-pack
  • binaryen (if you want to run wasm-opt manually)
  • Python3

It has been tested on Linux x86 and x64.

Binary optimizations

Edit build.sh and remove the wasm-opt call if you don't want to optimize the binary. Alternative, you can enable the optimizations in Cargo.toml, setting wasm-opt = true. Be careful though, since this only works if you are running on an x64 platforms. I should warn you that there are precompiled binaries for binaryen x86 in their github, and wasm-pack will try to use them but the packages actually contain x64 files that won't work. Here is the bug report rustwasm/wasm-pack#974
