Stream markdown to HTML using marked that later can be piped to response.

WARNING!!! Markdown wasn't intended to be streamable so this library has a lot of limitations. Splitting markdown in chunks might break code markup, folded lists and link references. Use this library only for very basic markdown. The better approach would be using a string instead. A detailed explanation of why Streamdown is not the best approach is written here.

pnpm i streamdown

import { createServer } from 'http'
import { streamdown } from 'streamdown'
import { createReadStream } from 'fs'

createServer((_, res) => {
  createReadStream('page.md').pipe(streamdown()).pipe(res)
}).listen(3000)

import { streamdown, Streamdown } from 'streamdown'

Create a new Streamdown transform stream with options for transform and MarkedOptions from marked

const md = new Streamdown({
  markedOptions: {
    headerIds: false
  },
  transformOptions: {
    encoding: 'utf8'
  }
})

Create a new Streamdown transform stream and return it.
