## Removing unused languages from dynamic import
|
|
|
|
If a locale is imported dynamically, then all locales from date-fns are loaded by webpack into a bundle (~160kb) or split across the chunks. This prolongs the build process and increases the amount of space taken. However, it is possible to use webpack to trim down languages using [ContextReplacementPlugin].
|
|
|
|
Let's assume that we have a single point in which supported locales are present:
|
|
|
|
`config.js`:
|
|
|
|
```js
|
|
// `see date-fns/src/locale` for available locales
|
|
export const supportedLocales = ["en-US", "de", "pl", "it"];
|
|
```
|
|
|
|
We could also have a function that formats the date:
|
|
|
|
```js
|
|
const getLocale = (locale) => import(`date-fns/locale/${locale}/index.js`); // or require() if using CommonJS
|
|
|
|
const formatDate = (date, formatStyle, locale) => {
|
|
return format(date, formatStyle, {
|
|
locale: getLocale(locale),
|
|
});
|
|
};
|
|
```
|
|
|
|
In order to exclude unused languages we can use webpacks [ContextReplacementPlugin].
|
|
|
|
`webpack.config.js`:
|
|
|
|
```js
|
|
import webpack from 'webpack'
|
|
import { supportedLocales } from './config.js'
|
|
|
|
export default const config = {
|
|
plugins: [
|
|
new webpack.ContextReplacementPlugin(
|
|
/^date-fns[/\\]locale$/,
|
|
new RegExp(`\\.[/\\\\](${supportedLocales.join('|')})[/\\\\]index\\.js$`)
|
|
)
|
|
]
|
|
}
|
|
```
|
|
|
|
This results in a language bundle of ~23kb .
