Vanilla JS quickstart

For non-React apps (or any framework you’d rather drive imperatively).

Booting WebContainer…

1. Install


pnpm add @mushi-mushi/web

2. Initialize

src/mushi.ts


import { initMushi } from '@mushi-mushi/web'
 
const mushi = initMushi({
  projectId: import.meta.env.VITE_MUSHI_PROJECT_ID,
  apiKey: import.meta.env.VITE_MUSHI_API_KEY,
})
 
window.addEventListener('beforeunload', () => mushi.flushOfflineQueueNow())

3. Submit


import { mushi } from './mushi'
 
document.querySelector('#report-bug')?.addEventListener('click', async () => {
  await mushi.submitReport({
    description: 'Login button does nothing on mobile Safari.',
    severity: 'medium',
  })
})

The widget (Shake-to-Report on touch devices, sticky button on desktop) mounts automatically with enableWidget: true, which is the default.
