Installation

yarn add @untemps/solid-readotron

Usage

Basic usage

<main>
	<Readotron selector=".text" />
	<section class="text">...</section>
</main>

API

Props	Type	Default	Description
selector	string	(required)	Selector of the element which contains the content to parse. See Selector
lang	string	'default'	Lang of the content. See Lang
template	string	'%time% min read'	Display template which contains dynamic tokens to be replaced by the parsed values. See Template

Selector

selector prop is mandatory as it points to which element contains the text content to parse. You can utilize any selector supported by the Web API querySelector function.
If several elements match the selector, it only parses the text of the first element in the array.

Lang

'lang' is an optional prop that designates the language of the text to parse. The component implements the @untemps/read-per-minute underhand package which returns an estimation based on the lang (language).
Reading rates by lang come from "How many words do we read per minute? A review and meta-analysis of reading rate" by Marc Brysbaert - Department of Experimental Psychology Ghent University

Lang	Rate
default	200
ar	181
zh	260
nl	228
en	236
fi	195
fr	214
de	260
he	224
it	285
ko	226
es	278
sv	218

If a lang is not defined or the provided lang is not listed, the default value (200) will be applied.

Example

<main>
	<Readotron selector=".text" lang="en" />
	<section class="text">...</section>
</main>

Template

You can customize the Readotron display by using the template prop: a template is a string with one or more tokens delimited with %

Available tokens

Token	Description
time	Estimated reading time (in minutes)
words	Number of words

Example

<main>
	<Readotron selector=".text" template="Reading Time: %time% minutes (%words% words)" />
	<section class="text">...</section>
</main>

Children

Another way to customize the Readotron display is to pass down a function as children.

Available arguments

Token	Description
time	Estimated reading time (in minutes)
words	Number of words
error	Parsing error if available

Example

<main>
    <Readotron selector=".text">
      {(time, words, error) => (
      <Show when={!error} fallback={<span class='error'>Oops</span>}>
        <span class='readotron'>
          {time} min read ({words} words)
        </span>
      </Show>``
      )}
    </Readotron>
    <section class="text">
        ...
    </section>
</main>
