WebAssembly.module.imports

The WebAssembly.imports() function returns an array containing descriptions of all the declared imports of the given Module.

Syntax

var custSec = WebAssembly.Module.imports(module);

Parameters

module

A WebAssembly.Module object.

Return value

An array containing objects representing the imported functions of the given module.

Exceptions

If module is not a WebAssembly.Module object instance, a TypeError is thrown.

Example

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.

fetch('simple.wasm').then(response =>
  response.arrayBuffer()
).then(bytes =>
  WebAssembly.compile(bytes)
).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" }
