> Easily remove unused Moment.js locales when building with webpack
## Why
75% (160 minified KBs)¹ of [Moment.js’](https://github.com/moment/moment) size are files used for localization. [They are always included](https://iamakulov.com/notes/webpack-front-end-size-caching/#moment-js) when you build your app with webpack.
You don’t need most of these files if your app is only available in a few languages. Use this plugin to strip these KBs and optimize the app!
¹ – tested with Moment.js 2.18.1
## Install
```sh
npm install --save-dev moment-locales-webpack-plugin
```
## Usage
```js
// webpack.config.js
const MomentLocalesPlugin = require('moment-locales-webpack-plugin');
module.exports = {
plugins: [
// To strip all locales except “en”
new MomentLocalesPlugin(),
// Or: To strip all locales except “en”, “es-us” and “ru”
// (“en” is built into Moment and can’t be removed)
new MomentLocalesPlugin({
localesToKeep: ['es-us', 'ru'],
}),
],
};
```
## Plugin Options
### **`localesToKeep: String[]`**
An array of locales to keep bundled (other locales would be removed).
Locale names follow Moment.js behavior – if a specific locale name (e.g. `ru-ru`) is absent, but a more generic locale (`ru`) is available, the generic one will be kept bundled.
### **`ignoreInvalidLocales: Boolean`**
A flag to ignore invalid or unsupported locales in the `localesToKeep` array.
Be careful! A typo in the `localesToKeep` array with this flag enabled will silently exclude the desired locale from your bundle.
