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 🙏

@ai37/copilotkit-md-renderer

v0.1.1

Published

CopilotKit assistant markdown renderer with KaTeX formula support, built on Streamdown. KaTeX core + extension points.

Readme

@ai37/copilotkit-md-renderer

Рендерер markdown ответов ассистента для CopilotKit v2 с поддержкой KaTeX-формул ($…$ / $$…$$) и безопасным sanitize. Обёртка над streamdown.

Ядро + точки расширения: компонент владеет порядком рехайп-пайплайна [rehypeKatex, …extra, rehypeSanitize], а приложение добавляет свои плагины/схему снаружи, не форкая компонент.

Установка

pnpm add @ai37/copilotkit-md-renderer
# peer: react ^18 || ^19

Важно: пакет не несёт CSS KaTeX. Подключи стили один раз в корне приложения:

import "katex/dist/katex.min.css"

Использование

Слот рендерера ассистента <CopilotChat>:

import { AssistantMarkdown } from "@ai37/copilotkit-md-renderer"

<CopilotChat
  chatView={{
    messageView: {
      assistantMessage: { markdownRenderer: AssistantMarkdown },
    },
  }}
/>

Точки расширения

| Проп | Назначение | | --- | --- | | content: string | Markdown-источник. | | extraRemarkPlugins?: PluggableList | Доп. remark-плагины, ПОСЛЕ remark-math. | | extraRehypePlugins?: PluggableList | Доп. rehype-плагины, ПОСЛЕ rehype-katex и ПЕРЕД rehype-sanitize. | | sanitizeSchema?: Schema | Схема финального sanitize. По умолчанию katexSchema. |

remarkPlugins/rehypePlugins намеренно недоступны — базовый KaTeX-пайплайн заменить нельзя, только дополнить.

Пример: своя rehype-надстройка

Если extra-плагин эмитит свою разметку, разреши её в sanitizeSchema (иначе sanitize её срежет):

import { AssistantMarkdown, katexSchema } from "@ai37/copilotkit-md-renderer"
import type { Schema } from "hast-util-sanitize"
import { myRehypePlugin } from "./myRehypePlugin"

const schema: Schema = {
  ...katexSchema,
  tagNames: [...(katexSchema.tagNames ?? []), "section"],
  attributes: {
    ...katexSchema.attributes,
    "*": [...((katexSchema.attributes?.["*"] as string[]) ?? []), "data-foo"],
  },
}

function MyRenderer(props: { content: string }) {
  return (
    <AssistantMarkdown
      {...props}
      extraRehypePlugins={[myRehypePlugin]}
      sanitizeSchema={schema}
    />
  )
}

Спредь katexSchema.attributes целиком — иначе потеряются per-tag KaTeX-атрибуты и формулы сломаются.
