@beacio/detect

Detect the WebBLE Safari Web Extension on iOS and guide users through install — extension state checks, an install banner, and a React provider.

Requires iOS 26.0+ Safari with the WebBLE app for the extension path. On browsers with native Web Bluetooth (Chrome, Edge) detection is a no-op.

Install

npm install @beacio/detect

Zero-config auto mode

Import once in your browser entry file. It detects the extension and, when missing on iOS Safari, shows a guided install prompt:

import '@beacio/detect/auto';

The auto entry reads an optional API key from <meta name="ioswebble-key" content="wbl_xxxxx"> or window.__IOSWEBBLE_KEY__.

Manual detection

import {
  getExtensionInstallState,
  isExtensionInstalled,
  isIOSSafari,
} from '@beacio/detect';

if (isIOSSafari()) {
  const state = await getExtensionInstallState();
  // 'not-installed' | 'installed-inactive' | 'active'

  if (state !== 'active') {
    // show your own UI, or use showInstallBanner() below
  }
}

Install banner

import { showInstallBanner, removeInstallBanner } from '@beacio/detect';

showInstallBanner({
  mode: 'sheet',              // 'sheet' (iOS bottom sheet, default) or 'banner'
  operatorName: 'FitTracker', // your app name shown in the prompt
  dismissDays: 14,            // suppress after dismiss
});

The banner's default CTA opens the guided setup flow at https://ioswebble.com/setup (install → enable the Safari extension → return to your page). Override with startOnboardingUrl or appStoreUrl.

Full init

import { initBeacio } from '@beacio/detect';

await initBeacio({
  operatorName: 'FitTracker',
  banner: { mode: 'sheet' },  // or false to disable
  onReady: () => console.log('extension active'),
  onInstalledInactive: () => console.log('installed, needs Safari activation'),
  onNotInstalled: () => console.log('not installed'),
});

State changes also dispatch a ioswebble:statechange CustomEvent on window.

React

import { BeacioProvider, useBeacio } from '@beacio/detect/react';

export default function Layout({ children }) {
  return <BeacioProvider>{children}</BeacioProvider>;
}

function Status() {
  const { state } = useBeacio();
  return <span>{state}</span>;
}
