reading-time

Calculate the amount of time a string would take to read.

Installation

npm i --save @hugodf/reading-time

Usage

const { readingTime } = require("reading-time");
// or
import { readingTime } from "reading-time";

const time = readingTime("My text...");
// 1, time to read in minutes

Advanced Usage

Pass a custom wordCount -> readingTime function

const readingTimeFunction = wordCount => {
  return wordCount / 100;
  // default divides by 200 and rounds to nearest integer > 0
};
const time = readingTime("My text...", readingTimeFunction);
// 0.02

Accessing the average reading time function

There is a built-in averageReadingTime function which uses 200 words per minute (average reading time).

This can be used to create a function to format the output without using a custom readingTime function eg. if the formatting in whole minutes is not acceptable

const { readingTime, averageReadingTime } = require("reading-time");
// or
import { readingTime, averageReadingTime } from "reading-time";

const roundedDownAverageReadingTimeFn = wordCount => {
  // Always round down the minutes.
  return Math.floor(averageReadingTime(wordCount));
};
const time = readingTime("My text...", roundedDownAverageReadingTimeFn);
// 0
