function App() {
const [name, setName] = createSignal("");
const [debug, setDebug] = createSignal("[debug]");
const [log, setLog] = createSignal("[log]");
const [error, setError] = createSignal("[error]");
let startTime: number;
let unwatch: Promise;
onMount(async () => {
try {
unwatch = watch(
"./",
(event) => {
const elapsedTime = performance.now() - startTime;
setLog(`Elapsed time: ${elapsedTime.toFixed(2)} ms\n` + JSON.stringify(event));
},
