### options.patterns

The (array of) pattern(s) to glob all files within the context.

* Default: `["**/*.*"]`
* Directly pass to [`glob-all(patterns)`](https://github.com/jpillora/node-glob-all#api)

### options.failOnUnused

Emit _error_ instead of _warning_ in webpack compilation result.

* Default: `false`
* Explicitly set it to `true` to enable this feature

### options.globOptions

The options object pass to second parameter of `glob-all`.

* Default: `{ignore: "node_modules/**/*"}`
* Directly pass to [`glob-all(pattern, globOptions)`](https://github.com/jpillora/node-glob-all#api), which then pass to [`glob(…, globOptions)`](https://github.com/isaacs/node-glob#options)

#### globOptions.ignore

Ignore pattern for glob. Can be a String or an Array of String.

* Default: `"node_modules/**/*"`
* Pass to: [`options.ignore`](https://github.com/isaacs/node-glob#options)

#### globOptions.cwd

Current working directory for glob. If you don't set explicitly, it defaults to the `context` specified by your webpack compiler at runtime.

* Default: `webpackCompiler.context`
* Pass to: [`options.cwd`](https://github.com/isaacs/node-glob#options)
* See also: [`context` in webpack](https://webpack.js.org/configuration/entry-context/#context)
