+# Request js
+## Frontend Helper
+Kleiner Helfer zur einfachen Kommunikation mit dem Backend was einen XCSRF Token erwartet. Durch einfachen aufruf von 'Post' oder 'Get' mit den Parametern 'url' und 'data' kann einfach ein ajax Request abgeschickt werden, der sich automatisch den XCSRF Token aus den Meta Infos des Headers nimmt.
+
+### Beispiel
+
+``` javaScript:
+import {Post} from 'Request.js'
+
+const url = 'https://example.com'; 
+const data = {foo:'bar', hip: 'hop'} 
+
+const {success, content, message} = await new Post(url, data); 
+if (!success) { 
+   // do some code for bad response 
+   return; 
+}
+// do some things with content...
+```
