How do I integrate Claude AI with a Node.js project

1. Install the `claude-ai` package via npm: `npm install claude-ai`[2]

2. Initialize a new Claude instance in your Node.js code, providing your Anthropic API key:

javascript
const { Claude } = require('claude-ai');
const claude = new Claude({ apiKey: 'your_anthropic_api_key' });

3. Use the Claude instance to start new conversations, send messages, and access the Claude API:

javascript
// Start a new conversation
const conversation = await claude.createConversation();

// Send a message to Claude
const response = await conversation.sendMessage('Tell me a haiku about trees.');

// Log the response from Claude
console.log(response.text);

4. (Optional) Implement a chatbot interface that prompts the user for input and displays Claude's responses:

javascript
const readline = require('readline');

const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout
});

rl.on('line', async (input) => {
  const response = await conversation.sendMessage(input);
  console.log(response.text);
});

5. (Optional) Define custom tools that extend Claude's capabilities by creating a `tools.js` file and integrating them into your conversation:

javascript
// tools.js
const tools = {
  myTool: {
    schema: { /* ... */ },
    handler: async ({ input }) => {
      // Implement custom tool logic here
      return 'Custom tool response';
    }
  }
};

module.exports = tools;

// index.js
const tools = require('./tools');
const response = await conversation.sendMessage('Call myTool with input', { tools });
console.log(response.text);

By following these steps, you can easily integrate the Claude AI Toolkit into your Node.js project and leverage Claude's natural language processing and generation capabilities to build intelligent applications.
