webpack and the Challenge of WebAssembly
summary
webpack integrates WebAssembly by treating .wasm modules as part of its JavaScript module graph, but faces concrete interoperability and lifecycle issues: timing of the imports object (imports are only available after instantiation), engine-specific differences in compilation/instantiation order, and lack of support for exporting memory/tables in some browsers. The talk describes race conditions for globals and function bindings when modules load, trade‑offs between synchronous and asynchronous instantiation for performance, and the need for wrappers, fallbacks, parallel compilation orchestration, and feature‑flagged workarounds while implementation remains work‑in‑progress with partial browser support.
