Estimated Reading Time for Blog Posts, Articles, etc.

A simple Kotlin/Java implementation of Medium's Read Time calculation.

Examples (TL;DR)

import net.thauvin.erik.readingtime.ReadingTime

...

val rt = ReadingTime(htmlText)
println(rt.calcEstimatedReadTime()) // eg: 2 min read

To get the estimated reading time in seconds use the calcReadingTimeInSec() function.
