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 🙏

🚀 快速开始

1. 准备术语表

创建 content/glossary.yml:

version: 1
terms:
  - id: mla
    label: MLA
    definition: |
      **Multi-head Latent Attention (MLA)** 是 DeepSeek-V2 引入的注意力机制创新。
      通过低秩压缩将 Key 和 Value 投影到潜在空间,大幅降低 KV Cache 显存占用。
    aliases:
      - Multi-head Latent Attention
      - 多头潜在注意力
    tags: [DeepSeek, Attention, KV Cache]
    sources:
      - type: paper
        title: "DeepSeek-V2: A Strong, Economical, and Efficient Mixture-of-Experts Language Model"
        url: "https://arxiv.org/abs/2405.04434"
    related: [kvcache, mqa, gqa]
    seeAlso: [/lab/deepseek-mla]

  - id: kvcache
    label: KV Cache
    definition: **Key-Value Cache** 是 Transformer 推理时缓存的 Key/Value 投影,随序列长度线性增长。
    aliases: [Key-Value Cache, 键值缓存]
    tags: [Inference, Memory]
    related: [mla, mqa, gqa]

2. 构建时集成

Next.js (App Router)

// lib/mdx.ts
import { rehypeTermTooltip } from '@wulutech/term-tooltip/rehype'

export const mdxOptions = {
  rehypePlugins: [[rehypeTermTooltip, { glossaryPath: 'content/glossary.yml' }]],
}

Astro

// astro.config.mjs
import rehypeTermTooltip from '@wulutech/term-tooltip/rehype'

export default defineConfig({
  markdown: {
    rehypePlugins: [[rehypeTermTooltip, { glossaryPath: 'content/glossary.yml' }]]
  }
})

通用 (unified/rehype)

import { unified } from 'unified'
import rehypeParse from 'rehype-parse'
import rehypeStringify from 'rehype-stringify'
import { rehypeTermTooltip } from '@wulutech/term-tooltip/rehype'

const html = await unified()
  .use(rehypeParse, { fragment: true })
  .use(rehypeTermTooltip, { glossaryPath: 'content/glossary.yml' })
  .use(rehypeStringify)
  .process('<p>MLA 优化了 KV Cache</p>')

3. 生成术语表 JSON

# 单次生成
npx @wulutech/term-tooltip generate --input content/glossary.yml --output public/glossary.json

# 开发模式监听
npx @wulutech/term-tooltip generate --input content/glossary.yml --output public/glossary.json --watch

或在 package.json 中:

{
  "scripts": {
    "generate:glossary": "@wulutech/term-tooltip generate --input content/glossary.yml --output public/glossary.json",
    "postinstall": "npm run generate:glossary"
  }
}

4. 客户端初始化

// app/layout.tsx (Next.js) 或 layouts/BaseLayout.astro
'use client'
import { initTermTooltip } from '@wulutech/term-tooltip/client'
import { useEffect } from 'react'

export function TermTooltipProvider() {
  useEffect(() => initTermTooltip({
    trigger: 'hover focus',
    delay: { show: 150, hide: 100 },
    debug: process.env.NODE_ENV === 'development',
  }), [])
  return null
}

🎨 主题定制

通过 CSS 变量覆盖(建议在全局 CSS 中):

:root {
  --term-tooltip-bg: #1a1f2e;
  --term-tooltip-border: #c9a962;
  --term-tooltip-text: #e8e4da;
  --term-tooltip-muted: #9ca3af;

  --term-tooltip-max-width: 320px;
  --term-tooltip-font: inherit;
  --term-tooltip-z-index: 9999;
}

/* 触发元素样式 */
.term-tooltip {
  border-bottom: 1px dotted var(--term-tooltip-border);
  cursor: help;
}
.term-tooltip:hover,
.term-tooltip:focus {
  border-bottom-style: solid;
  border-bottom-width: 2px;
}
