comark-reading-time

A document's word count and reading time, written to meta.readingTime while parsing. A Comark plugin for any renderer.

pnpm add comark comark-reading-time

import { parseMarkdown } from "comark";
import readingTime from "comark-reading-time";

const { meta } = await parseMarkdown(markdown, { plugins: [readingTime({ wordsPerMinute: 200 })] });
meta.readingTime; // { words: 1240, minutes: 7 }

Code blocks, frontmatter, and comments are left out; inline code counts. Chinese, Japanese, and Korean are counted by character, since they're written without spaces between words. minutes is rounded up, and 0 only for a document with no words. countWords(text) counts any string the same way.

It draws nothing and has no components: show the numbers in your layout.
