Syntax

WebAssembly.Module.imports(module);

Examples

Using imports

The following example (see imports.html source code; see it live also) compiles the loaded simple.wasm module. This module is then queried for its imports.

WebAssembly.compileStreaming(fetch('simple.wasm'))
.then(function(mod) {
  var imports = WebAssembly.Module.imports(mod);
  console.log(imports[0]);
});

The output looks like this:

{ module: "imports", name: "imported_func", kind: "function" }
