Building an AI Chatbot Interface in React Using AWS Bedrock

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);

Enter fullscreen mode Exit fullscreen mode

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.
