Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

ti-code-providers

Effect-native provider adapters for ti-code.

The current package includes OpenAI streaming, an experimental OpenAI Responses WebSocket transport, ChatGPT auth/model helpers with Codex Responses WebSocket as the default transport, and the OpenAI Codex OAuth helper used by the CLI. The Anthropic adapter remains deferred while the first vertical slice stays focused on the OpenAI/ChatGPT path.

Exports

  • ti-code-providers - main provider surface.
  • ti-code-providers/openai - OpenAI adapter with HTTP SSE by default and optional Responses WebSocket transport via TI_OPENAI_TRANSPORT=responses-websocket.
  • ti-code-providers/chatgpt - ChatGPT model and request helpers. The default transport is Codex Responses WebSocket with pre-event SSE fallback; pass transport: "sse" to force HTTP SSE.
  • ti-code-providers/auth-storage - file-backed auth storage boundary.
  • ti-code-providers/openai-codex-oauth - provider-neutral OAuth flow.
  • ti-code-providers/openai-codex-oauth-node - Node-specific OAuth helper.

Runtime

The public npm package targets Node.js 20 or newer. Runtime-specific portable bundles are produced by the CLI release workflow rather than this package.

The default OpenAI transport remains HTTP SSE. Responses WebSocket mode requires a runtime whose globalThis.WebSocket accepts handshake headers.

The ChatGPT/Codex Responses WebSocket path is now the default ChatGPT transport and is covered by deterministic provider tests for URL normalization, header/frame construction, event decoding, close errors, and pre-event SSE fallback. A live gpt-5.5 probe passed on 2026-05-24, and the adapter strips max_output_tokens from ChatGPT WebSocket frames because the live endpoint rejected that field. Use the secret-safe probe when validating another account, model, runtime, or header shape:

pnpm exec tsx packages/providers/scripts/probe-chatgpt-codex-wss.ts

See docs/research/chatgpt-codex-wss-validation.md for the evidence boundary and inferred details.
