# Webpack config for Flarum JS/TS compilation
This package generates a [Webpack](https://webpack.js.org) config object that will compile JavaScript for use in Flarum.
## Usage
**webpack.config.js**
```js
var config = require('flarum-webpack-config');
module.exports = config(options);
```
To merge in custom Webpack config options, use [webpack-merge](https://www.npmjs.com/package/webpack-merge).
### Webpack Bundle Analyzer
You can view a visual representation of your JS Bundle by building with Webpack Bundle Analyzer.
Add another build script to your `package.json` like the one below:
```json
{
"analyze": "npx cross-env ANALYZER=true npm run build"
}
```
## Typescript
You'll need to configure a `tsconfig.json` file to ensure your IDE sets up Typescript support correctly.
For details about this, see the [`flarum/flarum-tsconfig` repository](https://github.com/flarum/flarum-tsconfig)
## Options
### `useExtensions`
`Array<string>`, defaults to `[]`.
An array of extensions whose modules should be made available. This is a shortcut to add [`externals`](https://webpack.js.org/configuration/externals/) configuration for extension modules. Imported extension modules will not be bundled, but will instead refer to the extension's exports included in the Flarum runtime (ie. `flarum.extensions["vendor/package"]`).
For example, to access the Tags extension module within your extension:
**forum.js**
```js
import { Tag } from '@flarum/tags/forum';
```
**webpack.config.js**
```js
module.exports = config({
useExtensions: ['flarum/tags'],
});
```
