# Handling Dynamic Content

### Handling Dynamic Content

If your application dynamically loads or changes content, ensure that the stream container is present in the DOM before appending the video element:

```javascript
// Ensure the container is available in the DOM
const container = document.querySelector(`#${containerId}`);
if (!container) {
  // Logic to handle the absence of the container or retry appending
  throw new Error("Container is undefined.");
} else {
  // If the container exists, append the video element
  container.appendChild(application.rootElement);
}
```
