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 🙏

Readme

@agents-js/a2ui-host

Browser-side A2UI v0.9 host and bridge for agents-js.

Installation

bun add @agents-js/a2ui-host

API

Classes

  • A2uiBridge — Wires an {A2uiHost} onto a transport. The bridge owns no host state of its own — it is pure glue.
  • A2uiHost — Renders a live SurfaceGroupModel into a DOM mount point, applying A2UI lifecycle messages as they arrive.
  • SurfaceSession

Functions

  • createA2uiToolCallContentHandler
  • createBridgeSurfaceAdapter — Build a {HostSurfaceAdapter} that forwards every incoming A2UI lifecycle message through the given bridge. Pass the returned adapter into createA2uiToolCallContentHandler({ surfaceAdapter }) and ...

Interfaces

  • A2uiBridgeOptions — Options for constructing an {A2uiBridge}.
  • A2uiHostOptions — Options for constructing an {A2uiHost}.
  • CreateA2uiToolCallContentHandlerOptions
  • HostSurfaceAdapter
  • SurfaceEventSink — Minimal shape of a sink that can ferry surface events back to the agent. The <P> generic narrows the payload envelope. Consumers that know their wire contract at the wiring site can narrow once h...
  • SurfaceSessionOptions

Types

  • A2uiHostEventHandler — Callback invoked when a rendered ACP primitive emits an action. The <P> generic narrows the surface-event payload envelope so consumers that know their wire contract can typecheck payloads end-to...
  • SurfaceRenderer — Renderer function matching renderSurface from -js/a2ui-renderer. Injected so the host module stays renderer-agnostic (and unit-testable without a DOM-capable lit import chain). The renderer's...
