enablePreactPreset(options = {}) {
        webpackConfig.enablePreactPreset(options);

        return this;
    }
If enabled, a Preact preset will be applied to
the generated Webpack and Babel configuration.

```
Encore.enablePreactPreset()
```

If you wish to also use preact-compat (https://github.com/developit/preact-compat)
you can enable it by setting the "preactCompat" option to true:

```
Encore.enablePreactPreset({ preactCompat: true })
```

@param {{preactCompat?: boolean}} options
@returns {Encore}
