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 🙏

@ariaflow/livekit-plugin-transport-smartpbx

SmartPBX transport adapter for AriaFlow voice agents.

This package provides a reusable TransportAdapter implementation for SmartPBX-like WebSocket media streams so production code can live in a package, while playground examples stay thin.

Protocol stance:

  • Follow the SmartPBX AI Provider contract documented in SmartPBX AI Provider Docs version 2025.10.29.
  • Treat start, media, and WebSocket close as the normative protocol surface.
  • Do not invent SmartPBX protocol events for agent text or client turn markers.

Exports

  • SmartPBXTransportAdapter
  • SmartPBXAudioInput
  • SmartPBXAudioOutput
  • SmartPBXTextOutput
  • DEFAULT_SMARTPBX_SAMPLE_RATE
  • DEFAULT_WEBSOCKET_OPEN_STATE

Notes

  • This package focuses on transport I/O contract and stream lifecycle.
  • Codec conversion (G.711, Opus, resample strategy) can be composed in the host app through the onAudioFrame callback.
  • audioInput.endCurrentTurn() finalizes the local inbound stream only. It does not emit SmartPBX protocol messages back to the peer.
  • Outbound playback lifecycle is only reported after a frame is actually handed to onAudioFrame, so interruption logic is not driven by undeliverable audio.
  • Agent text is surfaced through an optional onText(text, session) host callback rather than through SmartPBX WebSocket messages, because the official protocol does not define a text event.
