To fix CometChat React UI Kit initializing twice in StrictMode, apply one-time init and login guards around the CometChatUIKit provider setup to prevent duplicate WebSocket connections and login request errors during development mounts.

To integrate CometChat with React Router v6, mount the provider at the app root and wire a specific route like /messages to the chat page using either createBrowserRouter or standard Routes and Route components.

CometChat message lists overflow the viewport in Vite when flexbox constraints are missing; applying minHeight zero and minWidth zero rules to your chat panels prevents the composer and message lists from breaking layout.

Yes, you need to import CometChat CSS variables manually in a CRA app by importing the cometchat chat-uikit-react css-variables css file exactly once at the root level to ensure correct UI rendering.

The best way to mount CometChatProvider in a plain React app is at the app root with one-time init guards and environment variables configured for Vite or CRA to safely handle routing and layout constraints.
