Building Your First AI Product: A Claude-Powered Chatbot With React

Let’s create a foundation you can build your startup upon. We’ll make a professional-grade AI chatbot that you can customize for various use cases:

Technical Setup

# Create a new React project
npm create vite@latest ai-startup-chatbot -- --template react
cd ai-startup-chatbot

# Install required dependencies
npm install @anthropic-ai/sdk
Enter fullscreen mode Exit fullscreen mode

Environment Configuration

Create a .env file:

VITE_ANTHROPIC_API_KEY=your-api-key-here
Enter fullscreen mode Exit fullscreen mode

In this file, you will add your Claude API key. You can get this from here. You can also add other environment variables to this file.


Core Implementation

Create a new react file, implementation.jsx and input the following code in it.

import React, { useState, useCallback } from "react";
import Anthropic from "@anthropic-ai/sdk";

const ClaudeChatbot = () => {
  const [messages, setMessages] = useState([]);
  const [inputText, setInputText] = useState("");
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState(null);

  const anthropic = useCallback(() => {
    const apiKey = import.meta.env.VITE_ANTHROPIC_API_KEY;
    if (!apiKey) {
      throw new Error("Missing Anthropic API key");
    }
    return new Anthropic({
      apiKey,
      dangerouslyAllowBrowser: true,
    });
  }, []);

  const sendMessageToClaude = async () => {
    if (!inputText.trim()) return;

    setLoading(true);
    setError(null);

    try {
      const messageHistory = messages.map((msg) => ({
        role: msg.isUser ? "user" : "assistant",
        content: msg.text,
      }));

      messageHistory.push({
        role: "user",
        content: inputText,
      });

      const response = await anthropic().messages.create({
        model: "claude-3-sonnet-20240229",
        max_tokens: 1024,
        messages: messageHistory,
      });

      if (!response?.content?.[0]?.text) {
        throw new Error("Invalid response from Claude");
      }

      setMessages((prev) => [
        ...prev,
        { isUser: true, text: inputText },
        { isUser: false, text: response.content[0].text },
      ]);
      setInputText("");
    } catch (err) {
      setError(err.message || "An error occurred while sending the message");
      console.error("Error:", err);
    } finally {
      setLoading(false);
    }
  };

  return (
    <div className="p-4 bg-gray-100 rounded-lg shadow-md">
      <h1 className="text-2xl font-bold mb-4 text-blue-500">Claude Chatbot</h1>

      {error && (
        <div
          className="bg-red-100 border border-red-400 text-red-700 px-4 py-3 rounded mb-4"
          role="alert"
        >
          <strong className="font-bold">Error:</strong> {error}
        </div>
      )}

      <div className="mb-4 h-64 overflow-y-auto border rounded-lg bg-white p-4">
        {messages.length === 0 ? (
          <div className="text-gray-400 text-center">
            Start a conversation with Claude!
          </div>
        ) : (
          <div className="flex flex-col space-y-2">
            {messages.map((message, index) => (
              <div
                key={index}
                className={`p-2 rounded-lg shadow-sm max-w-[80%] ${
                  message.isUser
                    ? "bg-blue-100 self-end"
                    : "bg-gray-100 self-start"
                }`}
              >
                <div className="text-xs text-gray-500 mb-1">
                  {message.isUser ? "You" : "Claude"}
                </div>
                {message.text}
              </div>
            ))}
          </div>
        )}
      </div>

      <div className="flex">
        <input
          className="flex-1 p-2 border rounded-lg shadow-sm focus:outline-none focus:ring-2 focus:ring-blue-500"
          placeholder="Type your message..."
          value={inputText}
          onChange={(e) => setInputText(e.target.value)}
          onKeyPress={(e) => {
            if (e.key === "Enter" && !e.shiftKey) {
              e.preventDefault();
              sendMessageToClaude();
            }
          }}
          disabled={loading}
        />
        <button
          className="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded-lg ml-2 shadow-sm focus:outline-none focus:ring-2 focus:ring-blue-500 disabled:opacity-50"
          onClick={sendMessageToClaude}
          disabled={loading || !inputText.trim()}
        >
          {loading ? "Sending..." : "Send"}
        </button>
      </div>
    </div>
  );
};

export default ClaudeChatbot;
Enter fullscreen mode Exit fullscreen mode

With everything running successfully, you should see an interface like this. From here, you can begin prompting.
