The Road to WASM

[Sam Gammon (sgammon)]

This discussion ticket can serve as a central place to keep track of Elide's incoming support for WASM. This includes compiling to WASM as well as loading and executing WASM components.

Blockers which need to be handled:

• Groundwork in Elide
  • Move annotations to universal package, or otherwise make them accessible
  • Abstraction of server package
  • Break up base library or make dependencies WASM-compatible
    • Kotlin MPP uuid
    • KotlinX api(...) exports
    • wasm target support feat: add wasm target support #343
      • uuid
      • core
      • base
      • test
      • model
      • ssr
      • proto-core
      • proto-kotlinx
• Research re/compile targets, runtimes
  • Wasmer
  • WasmEdge
  • Fermyon
  • CloudFlare Workers
  • Binaryen/Bazel/Gradle
• Upstream support (file blockers so we can track them)
  • WASM support is still experimental in Kotlin
  • GVM execution of WASM is still experimental
  • native-image can't yet compile to WASM as a target
  • GC proposal for WASM in browsers is still experimental
  • GC support is on the way for GraalVM
  • GVM will gain WASI support soon
  • GVM WASM component model support
