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 🙏

markstream-react

v0.0.20-beta.8

Published

React Markdown renderer optimized for large documents with progressive Mermaid rendering, streaming diff code blocks, and fast real-time preview. Built on stream-markdown AST for consistent rendering across frameworks. Perfect for documentation sites, AI

Readme

markstream-react

React renderer that consumes the structured AST output from stream-markdown-parser and renders it with lightweight semantic HTML components. This is the React counter-part to the Vue renderer that powers markstream-vue.

Development

pnpm --filter markstream-react dev

Build

pnpm --filter markstream-react build

Usage

import NodeRenderer from 'markstream-react'
import 'markstream-react/index.css'

export default function Article({ markdown }: { markdown: string }) {
  return (
    <NodeRenderer content={markdown} />
  )
}

You can also pass a pre-parsed nodes array if you already have AST data.

Tailwind

  • Non-Tailwind projects: keep importing markstream-react/index.css (includes precompiled utilities for the renderer).
  • Tailwind projects (avoid duplicate utilities): import markstream-react/index.tailwind.css and add require('markstream-react/tailwind') to your tailwind.config.js content.

Custom components (e.g. <thinking>)

Custom tag-like blocks are exposed as nodes with type: 'thinking' (the tag name, no angle brackets) when you register the tag in customHtmlTags or register a custom component mapping for it.

import type { NodeComponentProps } from 'markstream-react'
import NodeRenderer, { setCustomComponents } from 'markstream-react'

function ThinkingNode(props: NodeComponentProps<{ type: 'thinking', content: string }>) {
  const { node, ctx } = props
  return (
    <div className="thinking-node">
      <div className="thinking-title">Thinking</div>
      <NodeRenderer
        content={node.content}
        customId={ctx?.customId}
        isDark={ctx?.isDark}
        typewriter={false}
        batchRendering={false}
        deferNodesUntilVisible={false}
        viewportPriority={false}
        maxLiveNodes={0}
      />
    </div>
  )
}

setCustomComponents('chat', { thinking: ThinkingNode })
