Usage
Via polyfill-fastly.io
You can use polyfill-fastly.io URL Builder to create a polyfill script tag for Intl.PluralRules
. By default the created URL does not come with any locale data. In order to add locale data, append Intl.PluralRules.~locale.<locale>
to your list of features. For example:
<!-- Polyfill Intl.PluralRules, its dependencies & `en` locale data -->
<script src="https://polyfill-fastly.io/v3/polyfill.min.js?features=Intl.PluralRules,Intl.PluralRules.~locale.en"></script>
Simple
import '@formatjs/intl-pluralrules/polyfill'
import '@formatjs/intl-pluralrules/locale-data/en' // locale-data for en
Dynamic import + capability detection
import {shouldPolyfill} from '@formatjs/intl-pluralrules/should-polyfill'
async function polyfill(locale: string) {
const unsupportedLocale = shouldPolyfill(locale)
// This locale is supported
if (!unsupportedLocale) {
return
}
// Load the polyfill 1st BEFORE loading data
await import('@formatjs/intl-pluralrules/polyfill-force')
await import(`@formatjs/intl-pluralrules/locale-data/${unsupportedLocale}`)
}
