## What it is
The official TypeScript/JavaScript SDK for accessing Anthropic's Claude language model APIs from server-side applications. It provides a typed client for creating messages, streaming responses, and other Claude API operations across Node.js, Deno, Bun, and edge runtimes.

## Use cases
- call the claude api from a node.js app
- build a chatbot with anthropic claude in typescript
- stream claude responses in a serverless function
- integrate claude into a cloudflare worker
- send messages to claude and get completions
- use anthropic llm api with deno or bun

## When to choose
- you are building a server-side TypeScript or JavaScript application that needs Claude API access
- you want an officially maintained, typed client with streaming support
- you deploy to Node.js, Deno, Bun, or edge runtimes like Cloudflare Workers or Vercel Edge

## When to avoid
- you need to call Claude from React Native, which is not supported
- you want to run Claude calls directly in the browser without exposing API keys
- you are using a different language ecosystem with an official SDK available
