SSR / server-side rendering

The widget is browser-only. In server-rendered frameworks (Next.js, Nuxt, SvelteKit), initialize it inside a lifecycle hook that runs only in the browser: useEffect in React, onMounted in Vue, or afterNavigate in SvelteKit. Never call new ChatWidget() at the module level.

IE11

Internet Explorer 11 is not supported and there is no planned polyfill path. Shadow DOM and Custom Elements are not available in IE11.
