I'll create a simple chatbox with a mention functionality for the specified users. We'll use React and the AI SDK to build this component. Here's how we'll implement it:
This implementation creates a simple chatbox with the following features:
useChat hook for handling messages and input.To use this chatbox:
Remember to set up your OPENAI_API_KEY in your environment variables for the chat functionality to work properly.
This implementation provides a basic mention functionality. For a more robust solution in a production environment, you might want to consider using a dedicated mention library or implementing more advanced string matching and positioning algorithms.
I'll modify the chatbox component to display the mentions at the top of the input field, aligned with where the "@" symbol is typed. This will provide a more intuitive user experience for the mention functionality.
In this updated version, I've made the following changes:
mentionPosition state to keep track of where the "@" symbol is typed.Updated the useEffect hook to calculate the position of the "@" symbol:
getTextWidth to calculate the width of the text before the "@" symbol.Modified the rendering of the filtered users list:
mentionPosition.bottom: '100%') and given a small margin for visual separation.This implementation will display the mentions list at the top of the input field, aligned with where the "@" symbol is typed. The list will appear just above the cursor position when you type "@", providing a more intuitive and context-aware user experience.
Remember that this solution assumes a single-line input. For multi-line inputs or more complex scenarios, you might need to use a contenteditable div or a more sophisticated text editor component that can provide precise cursor position information.
