Global error handling

Errors and warnings are configured on the instance returned by createApp() and should be completed before mount():

import { createApp } from "@elfui/core";

const app = createApp(App);

app.config.errorHandler = (error, info) => {
  reportError(error, { info });
};

app.config.warnHandler = (message, ...args) => {
  console.warn("[ElfUI]", message, ...args);
};

app.mount("#app");

errorHandler receives component setup/render errors; warnHandler receives framework warnings in the App component context, such as expose overwriting the original host property.

WARNING

Do not put business recovery logic into the global handler. Partially recoverable errors should be handled by onErrorCaptured() or errorBoundary().
