claude-code-proxy

The Claude/Anthropic proxy layer on top of the generic core-proxy engine. It provides anthropicProfile — the config filename, tier order/fallback, tier regex, env-var prefix, default context/output limits, and the native Anthropic-shaped 429 response that the engine needs to route requests for Claude Code. It is consumed by claude-code-loader as a git submodule and installed/run by the dashboard sidecar.

This is a library repo consumed as a git submodule and bundled from source (the same treatment as core / core-auth / core-loader / core-proxy) — it is not published to npm.

This project carries no generic engine code — the routing engine (:34567 daemon, tier→provider chains, rate-limit fallback, model rewrite, the node↔web request adapter) lives entirely in core-proxy, nested here as a submodule. claude-code-proxy only supplies the Claude-specific profile that parameterizes that engine.

Structure

• core-proxy/ — the generic routing engine, nested as a git submodule (compiled separately into core-proxy/dist, excluded from this project's own tsconfig.json).
• src/profiles/anthropic.ts — anthropicProfile(), the Anthropic RoutingProfile (config file, tier order/fallback, tier regex, env prefix, default context/output, nativeRateLimit).
• src/index.ts — the public barrel: re-exports the entire core-proxy API plus anthropicProfile, so consumers import everything from one place.
• dist/ — compiled output (gitignored, never committed).

Usage

import { createProxyServer, makeDynamicResolver, anthropicProfile } from "./claude-code-proxy/dist/index.js";

const profile = anthropicProfile();
const resolveHandler = makeDynamicResolver(() =>
  listProviders().map((p) => ({ provider: p.provider, handlerPath: p.handlerPath }))
);
const server = createProxyServer({ configDir, profile, port: 34567, resolveHandler });
await server.listen();

Testing

npm run build && npx vitest run — builds the nested core-proxy engine first, then this project's own src, then runs the moved anthropicProfile tests plus a barrel smoke test asserting the re-exported surface.
