@jitl/quickjs-wasmfile-release-asyncify
Variant with separate .WASM file. Supports browser, NodeJS ESM, and NodeJS CJS.
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-wasmfile-release-asyncify"
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.
Exports: require import browser
Exports the following in package.json for the package entrypoint:
- undefined
- undefined
- Exports a browser-compatible ESModule.
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? wasm
Has a separate .wasm file. May offer better caching in your browser, and reduces the size of your JS bundle. If you have issues, try a 'singlefile' variant.
