@jitl/quickjs-browser-release-asyncify-singlefile
ESModule for browsers or browser-like environments
This generated package is part of quickjs-emscripten.
It contains a variant of the quickjs WASM library, and can be used with quickjs-emscripten-core.
import variant from "@jitl/quickjs-browser-release-asyncify-singlefile"
import { newQuickJSAsyncWASMModuleFromVariant } from "quickjs-emscripten-core"
const QuickJS = await newQuickJSAsyncWASMModuleFromVariant(variant)
This variant was built with the following settings:
Library: quickjs
The original bellard/quickjs library.
Release mode: release
Optimized for performance; use when building/deploying your application.
Module system: esm
This variant exports an ESModule, which is standardized for browsers and more modern browser-like environments. It cannot be imported from CommonJS without shenanigans.
Build run through the ASYNCIFY WebAssembly transform. Larger and slower. Allows synchronous calls from the WASM runtime to async functions on the host. The extra magic makes this variant slower than sync variants. Note that both variants support regular async functions. Only adopt ASYNCIFY if you need to!
Single-file, or separate .wasm file? singlefile
The WASM runtime is included directly in the JS file. Use if you run into issues with missing .wasm files when building or deploying your app.
