A lightweight eleventy plugin to display page/post reading time in minutes. No dependencies.

Install this package

npm i @myxotod/eleventy-plugin-readingtime

Add and register it inside your .eleventy.js config file

// .eleventy.js
const readingtime = require("@myxotod/eleventy-plugin-readingtime");

module.exports = (eleventyConfig) => {
  eleventyConfig.addPlugin(readingtime);
};

Finally use it in your code with the readingtime-filter

<div>Reading time: {{ post | readingtime }}</div>

Example output

<div>Reading time: ~3min</div>

You will have to pass the whole post or page to the filter as shown above.

You can pass several options when adding the plugin in your eleventy config file like so:

eleventyConfig.addPlugin(readingtime, {
  wordsPerMinute: 200,
  suffixDisplay: true,
  suffixText: 'min',
  prefixDisplay: true,
  prefixText: '~',
  verbose: false
});
