 ## Usage within svelte-kit project
 
 When using this component within a svelte-kit application it is necessary to add its two dependencies (`just-throttle` and `dayjs`) to the `config.kit.vite.optimizeDeps.include` array in `svelte.config.js`. Eg: your config should include the following:
 
 ```js
 const config = {
-	kit: {
-		vite: {
-			optimizeDeps: {
-				include: ['just-throttle', 'dayjs']
-			}
-		}
-	}
+  kit: {
+    vite: {
+      optimizeDeps: {
+        include: ['just-throttle', 'dayjs']
+      }
+    }
+  }
 };
 
 export default config;
 ```
