wasmer-unity

Aims to provide a C# interface of Wasmer, one of WebAssembly runtimes, integrating as a native plugin for Unity.

Motivation

There is no best library to use Wasm on Unity/C#.

• Wasmtime / wasmtime-dotnet
  • Wasmtime does not support iOS/Android platforms.
  • https://github.com/mochi-neko/wasmtime-dotnet-unity
• Wasmer / WasmerSharp
  • WasmerSharp embeds old version of Wasmter neaby 0.57.0 (2019).
• cs-wasm
  • Original implementation for Wasm by C#, without native plugins.

The following are the best features I think:

• uses a famous Wasm runtime as native plugin,
• maintained to stay close to the latest version of the original,
• supports major platforms: Windows, macOS(Intel/AppleSilicon), Linux, Android(ARM64/ARMv7) and iOS including AoT compilation.

Milestones

1. Implement minimal Wasm API for hello world.
2. Implement native Wasm API with samples.
3. Make demo on Unity.
4. Implement headless in Wasmer API.
5. Prepair Wasmer build environment for Android/iOS.
6. Implement WASI API.
7. Implement features in Wasmer API.
