Übersicht

Accessibility (a11y) for CometChat UI Kit integrations across all families — React, React Native, Angular, Android (V5/V6), iOS, Flutter. Covers WCAG 2.1 AA targets, keyboard navigation in chat, screen reader announcements (live regions for new messages), color contrast, focus management on call screens, motion-reduction support, and the cross-family checks that catch the common production a11y bugs. Cross-family — applies wherever the agent is checking accessibility.

Purpose

Accessibility for CometChat integrations. Out-of-the-box, the UI Kit components are mostly accessible — the kit's own buttons, inputs, and lists ship with semantic markup. Production gaps appear in the wiring around the kit: custom call surfaces, navigation, focus management on screen transitions, and contrast in custom themes.

Target: WCAG 2.1 AA. The skill writes code that meets this baseline.

The five gaps that trip integrations (any family)

Color contrast in custom themes. A brand color picked for "looks nice in the brand book" may be 3.2:1 against the text — fails AA's 4.5:1 minimum.
Focus management on chat screen entry. Tab/screen reader user lands on the chat screen but focus stays on the previous trigger button. They have to manually navigate into the message list every time.
No live region announcement for new messages. Screen reader users don't know a new message arrived unless they navigate the message list and hear the new item.
Keyboard-only users can't navigate the conversation list. Click handlers bound to <div> instead of <button> skip keyboard events.
Reduced-motion users see decorative animations. Typing-indicator dots, message bubble entrance animations, transition effects — should respect prefers-reduced-motion.

This skill addresses each one across families.

1. Color contrast — the theme audit

CometChat themes are CSS variables (web/RN) or color tokens (native/Flutter). Override a single color and you might fail AA.

Web / Angular — CSS variable contrast check

// scripts/check-contrast.ts (run in CI or as a one-shot)
function contrastRatio(hex1: string, hex2: string): number {
  const luminance = (hex: string) => {
    const rgb = hex.match(/\w\w/g)!.map(c => parseInt(c, 16) / 255).map(c =>
      c <= 0.03928 ? c / 12.92 : ((c + 0.055) / 1.055) ** 2.4
    );
    return 0.2126 * rgb[0] + 0.7152 * rgb[1] + 0.0722 * rgb[2];
  };
  const l1 = luminance(hex1);
  const l2 = luminance(hex2);
  return (Math.max(l1, l2) + 0.05) / (Math.min(l1, l2) + 0.05);
}

// Pull the values from your CSS variables
const fg = getComputedStyle(document.documentElement).getPropertyValue("--cometchat-text-color").trim();
const bg = getComputedStyle(document.documentElement).getPropertyValue("--cometchat-background-color").trim();
const ratio = contrastRatio(fg, bg);
if (ratio < 4.5) {
  console.warn(`Text/background contrast ${ratio.toFixed(2)}:1 fails WCAG AA (need ≥4.5:1)`);
}

In CI, add this to your test suite. The skill writes a starter version into tests/a11y/contrast.test.ts.

React Native / native / Flutter — manual audit at theme-design time

Use a contrast-checker tool (browser extensions, https://webaim.org/resources/contrastchecker/) on the theme tokens before shipping. There's no runtime DOM to audit on native.

The kit's default theme tokens pass AA. Custom palettes need the audit.

Common fail: brand purple #6750A4 against white background = 6.6:1 (passes). Same purple against #F0F0F0 light gray = 5.7:1 (passes). Same purple against #999999 muted gray = 2.8:1 (FAILS). Watch for muted backgrounds in dark-mode toggles, secondary buttons, and "subtle" surfaces.

2. Focus management on chat screen entry

When the user navigates to a chat screen (clicked a conversation, opened the chat tab, accepted a deep link), focus should land on a meaningful control — usually the message composer or the latest message.

React (web)

import { useEffect, useRef } from "react";

export function ChatScreen() {
  const composerRef = useRef<HTMLElement>(null);

  useEffect(() => {
    // After mount + animations, focus the composer
    const timer = setTimeout(() => {
      composerRef.current?.focus();
    }, 100);
    return () => clearTimeout(timer);
  }, []);

  return (
    <div>
      <CometChatMessageHeader />
      <CometChatMessageList />
      <CometChatMessageComposer ref={composerRef} />
    </div>
  );
}

The kit's CometChatMessageComposer is a plain function component (no forwardRef in v6), so passing it a ref is a no-op. Wrap it in a focusable container and reach the input through the DOM: composerRef.current?.querySelector("input, [contenteditable]")?.focus().

React Native

import { useRef, useEffect } from "react";
import { findNodeHandle, AccessibilityInfo } from "react-native";

export function ChatScreen() {
  const composerRef = useRef(null);

  useEffect(() => {
    const handle = findNodeHandle(composerRef.current);
    if (handle) {
      AccessibilityInfo.setAccessibilityFocus(handle);
    }
  }, []);

  return (
    <View>
      <CometChatMessageHeader />
      <CometChatMessageList />
      <CometChatMessageComposer ref={composerRef} />
    </View>
  );
}

Angular

@Component({...})
export class ChatComponent implements AfterViewInit {
  @ViewChild("composer") composer!: ElementRef;

  ngAfterViewInit() {
    setTimeout(() => this.composer.nativeElement.focus(), 100);
  }
}

Native Android (Kotlin)

override fun onResume() {
  super.onResume()
  composerView.requestFocus()
  composerView.sendAccessibilityEvent(AccessibilityEvent.TYPE_VIEW_FOCUSED)
}

Native iOS (Swift)

override func viewDidAppear(_ animated: Bool) {
  super.viewDidAppear(animated)
  UIAccessibility.post(notification: .screenChanged, argument: composerView)
}

Flutter

final FocusNode _composerFocus = FocusNode();

@override
void initState() {
  super.initState();
  WidgetsBinding.instance.addPostFrameCallback((_) {
    _composerFocus.requestFocus();
  });
}

// Then on the composer widget: focusNode: _composerFocus

3. Live region for new messages

Screen reader users need an audible announcement when a new message arrives — otherwise they have to navigate to the message list and re-read it.

Web / Angular — ARIA live region

<!-- A visually-hidden region that screen readers announce -->
<div
  aria-live="polite"
  aria-atomic="true"
  style="position: absolute; left: -9999px; height: 1px; width: 1px; overflow: hidden;"
  id="message-announcer"></div>

// Listen for new messages and announce
import { CometChat } from "@cometchat/chat-sdk-javascript";

const listenerId = "a11y-message-announcer";
CometChat.addMessageListener(listenerId, new CometChat.MessageListener({
  onTextMessageReceived: (msg: CometChat.TextMessage) => {
    const senderName = msg.getSender().getName();
    const text = msg.getText();
    const region = document.getElementById("message-announcer");
    if (region) {
      // Clearing first ensures the same text re-announces
      region.textContent = "";
      setTimeout(() => {
        region.textContent = `New message from ${senderName}: ${text}`;
      }, 100);
    }
  },
}));

aria-live="polite" waits for the user to finish speaking before announcing. Use aria-live="assertive" only for urgent messages (like incoming calls) — too aggressive for chat.

React Native

import { AccessibilityInfo } from "react-native";

CometChat.addMessageListener(listenerId, new CometChat.MessageListener({
  onTextMessageReceived: (msg) => {
    const text = `New message from ${msg.getSender().getName()}: ${msg.getText()}`;
    AccessibilityInfo.announceForAccessibility(text);
  },
}));

Native Android / iOS / Flutter

Each platform has an equivalent — Android View.announceForAccessibility(text), iOS UIAccessibility.post(notification: .announcement, argument: text), Flutter SemanticsService.announce(text, TextDirection.ltr). Same shape; the SDK callback is the trigger.

The kit's components are keyboard-accessible by default. Custom wrapping is what breaks it.

Anti-pattern — `<div onClick>` for clickable items

// ✗ WRONG — keyboard users can't activate
<div onClick={() => openConversation(c)}>{c.name}</div>

// ✓ RIGHT — `<button>` is keyboard + screen-reader native
<button onClick={() => openConversation(c)}>{c.name}</button>

// ✓ ALSO RIGHT — div with explicit ARIA + keyboard handlers
<div
  role="button"
  tabIndex={0}
  onClick={() => openConversation(c)}
  onKeyDown={(e) => {
    if (e.key === "Enter" || e.key === " ") {
      e.preventDefault();
      openConversation(c);
    }
  }}
>
  {c.name}
</div>

Skip links

For long conversation lists, add a skip-to-message-composer link:

<a href="#message-composer" class="skip-link">Skip to message composer</a>

.skip-link {
  position: absolute;
  left: -9999px;
  z-index: 999;
}
.skip-link:focus {
  left: 0;
  top: 0;
  background: white;
  padding: 8px;
}

The kit's components already include skip links where applicable; custom wrapping should preserve them.

Keyboard shortcuts

For productivity apps:

useEffect(() => {
  const handler = (e: KeyboardEvent) => {
    // Cmd/Ctrl + K → focus search
    if ((e.metaKey || e.ctrlKey) && e.key === "k") {
      e.preventDefault();
      searchRef.current?.focus();
    }
    // Escape → close any open thread / modal
    if (e.key === "Escape") {
      closeOpenThread();
    }
  };
  window.addEventListener("keydown", handler);
  return () => window.removeEventListener("keydown", handler);
}, []);

Document the shortcuts in your in-app help — discoverability matters.

5. Reduced motion

Animations help most users; they cause physical discomfort or distraction for users with vestibular disorders, ADHD, or who simply prefer less movement. WCAG 2.1 AA requires honoring the OS preference.

Web / Angular — CSS

@media (prefers-reduced-motion: reduce) {
  /* Disable kit animations + your custom ones */
  * {
    animation-duration: 0.01ms !important;
    animation-iteration-count: 1 !important;
    transition-duration: 0.01ms !important;
  }
}

React Native

import { AccessibilityInfo } from "react-native";

const [reduceMotion, setReduceMotion] = useState(false);

useEffect(() => {
  AccessibilityInfo.isReduceMotionEnabled().then(setReduceMotion);
  const sub = AccessibilityInfo.addEventListener("reduceMotionChanged", setReduceMotion);
  return () => sub.remove();
}, []);

// In animations
<Animated.View
  style={{
    transform: [{ scale: reduceMotion ? 1 : animatedValue }],
  }}
/>

Native iOS

let reduceMotion = UIAccessibility.isReduceMotionEnabled
if !reduceMotion {
  UIView.animate(withDuration: 0.3) { ... }
} else {
  // Apply final state without animation
}

Native Android

val reduceMotion = Settings.Global.getFloat(
  contentResolver, Settings.Global.ANIMATOR_DURATION_SCALE, 1.0f
) == 0.0f

Flutter

final reduceMotion = MediaQuery.of(context).disableAnimations;

Übersicht

Purpose

The five gaps that trip integrations (any family)

1. Color contrast — the theme audit

Web / Angular — CSS variable contrast check

React Native / native / Flutter — manual audit at theme-design time

2. Focus management on chat screen entry

React (web)

React Native

Angular

Native Android (Kotlin)

Native iOS (Swift)

Flutter

3. Live region for new messages

Web / Angular — ARIA live region

React Native

Native Android / iOS / Flutter

4. Keyboard navigation

Anti-pattern — <div onClick> for clickable items

Skip links

Keyboard shortcuts

5. Reduced motion

Web / Angular — CSS

React Native

Native iOS

Native Android

Flutter
