- Add 17 new integration tests: CORS edge cases (disallowed origins, no-origin header, OPTIONS for disallowed origin), auth (401/pass-through), and error handling (400/502/404) for /v1/chat/completions Closes #14, closes #16 - Add ESLint with flat config, npm run lint script, and Lint job in CI Closes #15 - Improve README with quickstart section, npm install instructions, and corrected package name; add type column to env vars table Closes #17
- Implement streaming for POST /v1/chat/completions (issue #11): subscribe to opencode event stream, pipe message.part.updated deltas as SSE chat.completion.chunk events, finish on session.idle - Implement streaming for POST /v1/responses (issue #11): emit response.created / output_text.delta / response.completed events - Fix provider-agnostic system prompt hint (issue #12): remove 'OpenAI-compatible' wording so non-OpenAI models are not confused - Add TextEncoder and ReadableStream to ESLint globals - Add streaming integration tests (happy path, unknown model, session.error)
- Extract createSseQueue() helper, eliminating duplicated SSE queue pattern in /v1/chat/completions and /v1/responses streaming branches (closes #34) - Add tests for GET /v1/models happy path, empty providers, and error path (closes #33) - Add tests for POST /v1/responses: happy path, validation, streaming, session.error (closes #32) - Fix package.json description to be provider-agnostic (closes #35) - Add engines field declaring bun >=1.0.0 requirement (closes #35) - Line coverage: 55% -> 89%, function coverage: 83% -> 94%
- POST /v1/messages — Anthropic Messages API with streaming (SSE) - POST /v1beta/models/:model:generateContent — Gemini non-streaming - POST /v1beta/models/:model:streamGenerateContent — Gemini NDJSON streaming - New helpers: normalizeAnthropicMessages, normalizeGeminiContents, extractGeminiSystemInstruction, mapFinishReasonToAnthropic/Gemini - 35 new tests (77 -> 112 total, all passing) - Update README to document all supported API formats Closes #38, #39
- Lead with value proposition, ASCII diagram, and feature table - Quickstart reduced to 4 steps; works in under 60 seconds - SDK examples for OpenAI, Anthropic, Gemini (JS+Python), LangChain - UI integration guides: Open WebUI, Chatbox, Continue, Zed - Reference section kept concise; full prose docs moved inline - package.json: sharper description, 20 keywords covering all search terms (openai-compatible, anthropic, gemini, ollama, langchain, open-webui, llm-proxy, ai-gateway, local-llm, github-copilot, model-router, …)

Summary
Access-Control-Allow-Originheader: whenOPENCODE_LLM_PROXY_CORS_ORIGINis set to a specific origin, the header now reflects the actual requestOriginvalue (if it matches) rather than always echoing the configured value verbatim. This is the correct CORS behaviour and ensures browsers accept the response.const allowOrigin = configuredOrigin === "*" ? "*" : configuredOriginwas a no-op — both branches returnedconfiguredOriginunchanged.
