+and add an `ignores` rule containing paths to be ignored. Here is an example preserving default hapi rules:
+```javascript
+import HapiPlugin from '@hapi/eslint-plugin';
+
+export default [
+    {
+        ignores: ['node_modules/*', '**/vendor/*.js'],
+    },
+    ...HapiPlugin.configs.module,
+];
 ```
