The query is also [Browserslist compatible](https://github.com/browserslist/browserslist). See [Browserslist Best Practices](https://github.com/browserslist/browserslist#best-practices) for more details.

If it's not set, plugin-legacy will load [the browserslist config sources](https://github.com/browserslist/browserslist#queries) and then fallback to the default value.

Note: if additional polyfills are needed for both the modern and legacy chunks, they can simply be imported in the application source code.

### `ignoreBrowserslistConfig`

- **Type:** `boolean`
- **Default:** `false`

`@babel/preset-env` automatically detects [`browserslist` config sources](https://github.com/browserslist/browserslist#browserslist-):

- `browserslist` field in `package.json`
- `.browserslistrc` file in cwd.

Set to `true` to ignore these sources.
