Claude TypeScript SDK
Quick Start
bash
npm install @anthropic-ai/sdk
export ANTHROPIC_API_KEY='your-key'
typescript
import Anthropic from '@anthropic-ai/sdk';
const client = new Anthropic();
const message = await client.messages.create({
model: 'claude-opus-4-5-20251101',
max_tokens: 1024,
messages: [{ role: 'user', content: 'Hello!' }],
});
Core Patterns
Basic Message
typescript
const message = await client.messages.create({
model: 'claude-opus-4-5-20251101',
max_tokens: 1024,
messages: [{ role: 'user', content: 'Your prompt' }],
});
console.log(message.content[0].type === 'text' && message.content[0].text);
Streaming
typescript
const stream = client.messages.stream({
model: 'claude-opus-4-5-20251101',
max_tokens: 1024,
messages: [{ role: 'user', content: 'Write a poem' }],
});
stream.on('text', (text) => process.stdout.write(text));
const final = await stream.finalMessage();
Tool Use
typescript
const tools: Anthropic.Tool[] = [{
name: 'get_weather',
description: 'Get weather for a location',
input_schema: {
type: 'object',
properties: {
location: { type: 'string', description: 'City name' },
},
required: ['location'],
},
}];
const response = await client.messages.create({
model: 'claude-opus-4-5-20251101',
max_tokens: 1024,
tools,
messages: [{ role: 'user', content: 'Weather in NYC?' }],
});

Error Handling
typescript
try {
const message = await client.messages.create({...});
} catch (error) {
if (error instanceof Anthropic.APIError) {
console.error(`Status: ${error.status}, Message: ${error.message}`);
}
}
