  +
  +A 0 dependency wrapper around the Node.JS & Browser `WebAssembly` instance, which adds support for [`asyncify`](https://emscripten.org/docs/porting/asyncify.html), enabling the use of async host import functions.
  +
  +## Usage
  +
  +```typescript
  +import { AsyncWasmInstance } from "@polywrap/asyncify-js";
  +
  +// module.wasm must be asyncify enabled
  +const module: ArrayBuffer = getModule("./module.wasm");
  +const memory = new WebAssembly.Memory({ initial: 1 });
  +
  +const instance = await AsyncWasmInstance.createInstance({
  + module,
  + imports: {
  + my: {
  + custom_import: async (arg: number): Promise<number> => {
  + return await someAsyncCall(arg);
  + }
  + },
  + env: {
  + memory
  + }
  + }
  +});
  +
  +await instance.exports.main();
  +```
