anthropics/anthropic-sdk-typescript

Access to Anthropic's safety-first language model APIs in TypeScript

What it solves

It provides a standardized way for developers to integrate Claude AI capabilities into server-side TypeScript or JavaScript applications without having to manually construct API requests.

How it works

The SDK acts as a wrapper around the Claude API, allowing developers to initialize a client with an API key and use typed methods (such as messages.create) to send prompts and receive responses from Claude models.

Who it’s for

Software engineers building applications with TypeScript or JavaScript across various runtimes, including Node.js, Deno, Bun, Cloudflare Workers, and Vercel Edge Runtime.

Highlights

  • Support for multiple modern JS runtimes (Node.js, Deno, Bun).
  • Compatibility with edge computing environments like Cloudflare Workers and Vercel Edge.
  • Built-in support for TypeScript 5.0+ for better type safety.
  • Optional browser support via the dangerouslyAllowBrowser flag.

    A marketplace of LSP server definitions that lets Claude Code (Anthropic’s AI coding assistant) provide IDE‑like features—go‑to‑definition, hover, find‑references, etc.—for dozens of languages. Install Claude Code ≥ 2.1.50, run `npx tweakcc --apply` to patch it, add the marketplace via `/plugin marketplace add Piebald‑AI/claude‑code‑lsps`, then install the underlying language‑server binaries (rust‑analyzer, pyright, clangd, etc.) as instructed. The repo includes validation scripts to keep the marketplace JSON in sync with the `.lsp.json` configs.
