How to use quickjs-emscripten inside an ESM Service Worker? #222
Description
I'm trying to use quickjs-emscripten inside a Service Worker that is written as an ECMAScript module (ESM).
However, it fails to execute due to the use of dynamic import() inside the library.
Since dynamic imports are not allowed in Service Workers, is there any workaround to make quickjs-emscripten work in this environment?
example:
// worker.js
import { getQuickJS } from 'https://esm.sh/quickjs-emscripten@0.31.0';
async function main() {
const QuickJS = await getQuickJS()
const vm = QuickJS.newContext()
const world = vm.newString("world")
vm.setProp(vm.global, "NAME", world)
world.dispose()
const result = vm.evalCode(`"Hello " + NAME + "!"`)
if (result.error) {
console.log("Execution failed:", vm.dump(result.error))
result.error.dispose()
} else {
console.log("Success:", vm.dump(result.value))
result.value.dispose()
}
vm.dispose();
}
main();<!-- index.html -->
