# Zoom Meeting SDK Web - Client View

Full-page Zoom meeting experience embedded in your web application. Client View provides the familiar Zoom interface with minimal customization needed.

## Overview

Client View uses the `ZoomMtg` global singleton to render a full-page meeting experience identical to the Zoom Web Client.

| Aspect | Details |
|--------|---------|
| **API Object** | `ZoomMtg` (global singleton) |
| **API Style** | Callback-based |
| **UI** | Full-page takeover |
| **Password param** | `passWord` (capital W) |
| **Events** | `inMeetingServiceListener()` |
| **Best For** | Quick integration, standard Zoom UI |

## Installation

### NPM

```bash
npm install @zoom/meetingsdk --save
```

```javascript
import { ZoomMtg } from '@zoom/meetingsdk';
```

### CDN

```html
<script src="https://source.zoom.us/{VERSION}/lib/vendor/react.min.js"></script>
<script src="https://source.zoom.us/{VERSION}/lib/vendor/react-dom.min.js"></script>
<script src="https://source.zoom.us/{VERSION}/lib/vendor/redux.min.js"></script>
<script src="https://source.zoom.us/{VERSION}/lib/vendor/redux-thunk.min.js"></script>
<script src="https://source.zoom.us/{VERSION}/lib/vendor/lodash.min.js"></script>
<script src="https://source.zoom.us/zoom-meeting-{VERSION}.min.js"></script>
```

## Complete Initialization Flow

```javascript
// Step 1: Check browser compatibility
console.log('Requirements:', ZoomMtg.checkSystemRequirements());

// Step 2: Set CDN path (optional - for China or custom hosting)
// ZoomMtg.setZoomJSLib('https://source.zoom.us/{VERSION}/lib', '/av');

// Step 3: Preload WebAssembly modules
ZoomMtg.preLoadWasm();
ZoomMtg.prepareWebSDK();

// Step 4: Load language resources
ZoomMtg.i18n.load('en-US');
ZoomMtg.i18n.onLoad(() => {
  
  // Step 5: Initialize SDK
  ZoomMtg.init({
    leaveUrl: '/meeting-ended',
    patchJsMedia: true,
    disableCORP: !window.crossOriginIsolated,
    success: () => {
      console.log('SDK initialized');
      
      // Step 6: Join meeting
      const joinPayload = {
        signature: signature,
        meetingNumber: meetingNumber,
        userName: userName,
        passWord: passWord,
        success: (res) => {
          console.log('Joined meeting');

          // Step 7: Post-join operations
          ZoomMtg.getAttendeeslist({});
          ZoomMtg.getCurrentUser({
            success: (res) => console.log('Current user:', res.result.currentUser)
          });
        },
        error: (err) => console.error('Join failed:', err)
      };

      // IMPORTANT: only include optional fields when they have real values
      // Passing undefined for some optional fields can cause runtime join errors
      if (userEmail) joinPayload.userEmail = userEmail;
      if (tk) joinPayload.tk = tk;
      if (zak) joinPayload.zak = zak;

      ZoomMtg.join(joinPayload);
    },
    error: (err) => console.error('Init failed:', err)
  });

## Rate Limits

| Method | Limit |
|--------|-------|
| `join()` | 10 seconds |
| `callOut()` | 10 seconds |
| `mute()` | 1 second |
| `muteAll()` | 5 seconds |

## DOM Elements

The SDK automatically adds these elements:
- `#zmmtg-root` - Main meeting container
- `#aria-notify-area` - Accessibility announcements

Do NOT manually create or remove these.

### SPA (React/Next) Overlay Gotcha

If you "join" but see a blank/black area or your app shell instead of the meeting UI, the Zoom UI can be rendering **behind** your app layout. Ensure `#zmmtg-root` occupies the viewport and is above other fixed elements:

```css
#zmmtg-root {
  position: fixed !important;
  inset: 0 !important;
  z-index: 9999 !important;
}
```

### Join Payload Sanitization Gotcha

If `ZoomMtg.join()` succeeds partially but the screen turns black and console shows errors like `Cannot read properties of undefined (reading 'toString')`, sanitize optional fields before calling join.

Do not pass optional keys with `undefined` values (`userEmail`, `tk`, `zak`, etc.). Build a payload and only attach those keys when they are non-empty strings.

Also prefer `defaultView: 'speaker'` during `ZoomMtg.init()` unless you have SharedArrayBuffer/gallery-view prerequisites fully configured.
