A [medium](https://medium.com/)'s like reading time estimator with
internationalization support.

## Documentation

Reading Time Estimator was created to provide an estimate of how long to read an
article or blog as seen on [medium](https://medium.com/).

### Installation

With NPM

```bash
  npm install reading-time-estimator
```

or Yarn

```bash
  yarn add reading-time-estimator
```

### API

The API is fairly simple. `readingTime` accepts the text to analyze plus an optional options object.

Per default the locale is set to english `en`.

Per default the words per minute is set to `200`.

Inputs are parsed as Markdown and sanitized as HTML automatically before word counting.

You can also provide `translations` to override locale strings or `htmlSanitizerOptions` to customize how markup is handled.

At the moment it supports these locales: `'en', 'fr', 'es', 'zh-cn', 'zh-tw', 'ja', 'de', 'pt-br', 'tr', 'ro', 'bn', 'sk', 'cs', 'ru', 'vi', 'it', 'id' and 'hi'`

### Usage

Try it live [here](https://codesandbox.io/s/condescending-rosalind-lll23r?file=/src/App.tsx)

```typescript
import { readingTime } from 'reading-time-estimator'

const text = 'some text to parse'

// custom words per minute
const result = readingTime(text, { wordsPerMinute: 10 })

// output:
// {
//   minutes: 4,
//   words: 43,
//   text: `4 min read`
// }

// with french locale
import { fr } from 'reading-time-estimator/i18n/fr'

const frenchResult = readingTime(text, {
  wordsPerMinute: 10,
  language: 'fr',
  {
    fr,
  },
})

// output:
// {
//   minutes: 4,
//   words: 43,
//   text: `4 min de lecture`
// }
```

## Why Not ...?

### reading-time

This [package](https://www.npmjs.com/package/reading-time) does not offer
internationalization support which was a must for me.
