WaEmbedderEx

Idiomatic Elixir wrapper over wa_embedder, the Erlang WebAssembly→BEAM compiler core. WaEmbedder.compile/1..4 parses a .wasm binary, translates it to Erlang abstract format, compiles and loads it as a native BEAM module, and raises %WaEmbedder.ImportError{} on unsatisfiable imports.

This package is a thin shim; the compiler pipeline lives in the pure-Erlang :wa_embedder core (usable directly from Erlang without Elixir).

Installation

def deps do
  [{:wa_embedder_ex, "~> 0.1"}]
end

Usage

{:module, mod} = WaEmbedder.compile("path/to/module.wasm")
mod.some_exported_fun(arg)

For modules with imports, pass an imports map:

WaEmbedder.compile("mod.wasm", %{"env" => %{"add" => {MyMod, :add}}}, [])
