 In order for the compiler to know that you are using import maps, you need to import the dependencies as follows:
 
 ```javascript
-import moment from "map:moment";
-import axios from "map:axios";
+import moment from "moment";
+import axios from "axios";
 ```
 
-> **note** this syntax is inspired by how [node js 15](https://nodejs.org/api/esm.html#esm_node_imports) built in modules are imported
+> **note** you can use import maps inside svelte components
 
 ### Manage import maps dependencies via [trex](https://github.com/crewdevio/Trex)
