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 🙏

对话 UI(UAiChat)与 UI 无关的 useChat 状态机。按 transport 形态接入两种工具来源。

客户端驱动

传入函数型 ChatTransport(通常 createOpenAITransport)和带 execute 的 ChatTool[]。前端持有历史,每轮把全量消息发给 OpenAI 兼容 SSE 端点,并在本地执行工具、维护队列与 needsConfirm。

import { createOpenAITransport, type ChatTool } from '@veltra/ai'

const transport = createOpenAITransport({
  providers: [{ id: 'openai', label: 'OpenAI', endpoint: '/ai/chat/completions', models: [...] }]
})

const tools: ChatTool[] = [
  {
    name: 'ping',
    description: '探测',
    parameters: { type: 'object', properties: {} },
    execute: async () => ({ ok: true })
  }
]

已有调用方无需改代码:ChatTransport / ChatTool.execute 必填签名不变。

服务端驱动

传入 createServerTransport(adapter)。adapter 只做协议翻译(订阅事件流、把 send / cancel / respond / selectModel / fetchHistory 打到远端)。包内完成 seq 校验、断线补拉、动作去重,再 fold 成消息 / 队列 / 作业。

import { createServerTransport, type ChatSessionAdapter } from '@veltra/ai'

const transport = createServerTransport(adapter)

此模式下 tools 只作按 name 的可选渲染元信息(ChatToolMeta),前端不定义、不执行工具。未注册的工具名走通用工具卡片。

本包不含 bedrock / DSH 桥

不实现、不导出 createBedrockTransport。DeepSeek harness(DSH)的 HTTP/WS 与 bedrock 适配由其它仓库提供 ChatSessionAdapter。
