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 🙏

Các entry point

Package được tách thành 3 subpath import để tránh kéo theo dependency không cần thiết:

| Import | Môi trường | Mục đích | | ---------------------- | --------------- | ----------------------------------------------------------------------- | | @v-miniapp/ai/server | Node.js | Khởi tạo MCP server, đăng ký tool / resource / prompt / skill | | @v-miniapp/ai/web | Browser (React) | Hooks và components để xây widget chạy bên trong host AI | | @v-miniapp/ai/apis | Browser | Truy cập trực tiếp adaptor (callTool, openDeeplink, reportAnalytics, …) |

Phía Server — @v-miniapp/ai/server

import {
  McpServer,
  McpTool,
  createStructuredResult,
} from '@v-miniapp/ai/server'
import { z } from 'zod'

const listTodos = new McpTool({
  name: 'list-todos',
  resourceName: 'todo-widget',
  config: {
    title: 'List todos',
    description: 'Trả về danh sách todo hiện tại',
    inputSchema: {},
  },
  handler: async () => {
    const todos = await db.todos.findMany()
    return createStructuredResult({ todos })
  },
})

const addTodo = new McpTool({
  name: 'add-todo',
  resourceName: 'todo-widget',
  config: {
    title: 'Add todo',
    inputSchema: { text: z.string().min(1) },
  },
  handler: async ({ text }) => {
    const todos = await db.todos.create({ text })
    return createStructuredResult({ todos })
  },
})

const server = new McpServer()
  .registerResources(['todo-widget'])
  .registerSkills(['expert-todo'])
  .registerTool(listTodos)
  .registerTool(addTodo)

await server.run()

Phía Widget — @v-miniapp/ai/web

import {
  AppProvider,
  useToolInfo,
  useCallTool,
  useWidgetState,
  getStructuredResult,
} from '@v-miniapp/ai/web'

function TodoWidget() {
  // Quan sát tool do AI gọi (passive)
  const toolInfo = useToolInfo<'list-todos'>()
  const data = getStructuredResult(toolInfo)

  // Gọi tool từ widget (active)
  const addTool = useCallTool('add-todo')

  // State được sync với host
  const [filters, setFilters] = useWidgetState<{ query: string }>({ query: '' })

  if (toolInfo.isPending) return <Skeleton />
  if (toolInfo.isError) return <ErrorView error={toolInfo.error} />

  return (
    <div>
      <input
        value={filters.query}
        onChange={e => setFilters({ query: e.target.value })}
      />
      <ul>
        {data?.todos.map(t => (
          <li key={t.id}>{t.text}</li>
        ))}
      </ul>
      <button
        disabled={addTool.isPending}
        onClick={() => addTool.callTool({ text: 'Buy milk' })}>
        {addTool.isPending ? 'Adding…' : 'Add'}
      </button>
    </div>
  )
}

export default function App() {
  return (
    <AppProvider loadingComponent={() => <Skeleton />}>
      <TodoWidget />
    </AppProvider>
  )
}
