Introduction
AI-powered applications are transforming modern software. While much focus is on AI models, the frontend experience plays a critical role in usability.
In this blog, I’ll explain how to build an AI chatbot interface using React while integrating AWS Bedrock from a frontend perspective.
1. Application Architecture
Typical flow:
React UI → Bedrock API → AI Model → Response → UI
Frontend focuses on:
Message handling
UI responsiveness
Error and loading states
2. Designing the Chatbot UI
Essential UI elements:
User and bot message bubbles
Typing indicator
Scroll-to-latest-message
Good UI design improves user trust and engagement.
3. Managing Chat State in React
State includes:
Messages array
Loading state
Error state
Example:
const [messages, setMessages] = useState([]);
const [loading, setLoading] = useState(false);
4. Integrating AWS Bedrock APIs
Key steps:
Send user prompt
Receive AI-generated response
Append response to chat history
Handle failures gracefully to avoid breaking the user experience.
5. Enhancing User Experience
Disable input during response generation
Smooth scrolling
Display fallback messages on errors
Conclusion
AI applications are incomplete without a smooth frontend experience. React developers who understand AI integrations stand out in the job market and future-proof their careers.
