{export: 'buffer'}
import wasmCode from "./lib.wasm"; WebAssembly.compile(wasmCode).then(module => { const instance = new WebAssembly.Instance(module); console(instance.exports.add(1, 2)); // 3 });
{export: 'module'}
import wasmModule from "./lib.wasm"; const instance = new WebAssembly.Instance(wasmModule); console(instance.exports.add(1, 2)); // 3
{export: 'instance'}
import wasm from "./lib.wasm"; console(wasm.exports.add(1, 2)); // 3
{export: 'async'}
import wasmInstantiate from "./lib.wasm"; wasmInstantiate(importObject | undefined).then(({ instance, module }) => { console(instance.exports.add(1, 2)); // 3 // create different instance, extra will be called in different environment const differentInstance = new WebAssembly.Instance(module); console(differentInstance.exports.add(1, 2)); // 6 });
{export: 'async-instance'}
import wasmInstantiate from "./lib.wasm"; wasmInstantiate(importObject | undefined).then(instance => { console(instance.exports.add(1, 2)); // 3 });
{export: 'async-module'}
import wasmInstantiate from "./lib.wasm"; wasmCompile(importObject | undefined).then(module => { const differentInstance = new WebAssembly.Instance(module); console(differentInstance.exports.add(1, 2)); // 3 });
