+Additionally you would need to add the following `transform` properties to your `.swcrc` file: `legacyDecorator`, `decoratorMetadata`:
+
+```json
+{
+  "$schema": "https://json.schemastore.org/swcrc",
+  "sourceMaps": true,
+  "jsc": {
+    "parser": {
+      "syntax": "typescript",
+      "decorators": true,
+      "dynamicImport": true
+    },
+    "transform": {
+      "legacyDecorator": true,
+      "decoratorMetadata": true
+    },
+    "baseUrl": "./"
+  },
+  "minify": false
+}
+```
+
 If you use NestJS CLI Plugins in your project, you'll have to run `PluginMetadataGenerator` manually. Navigate to [this section](/recipes/swc#monorepo-and-cli-plugins) to learn more.
