+# Custom method
+
+This is an example to show how to make a custom method.
+
+This example focus on the `TRACE` method, to send to a remote user all modified/created resources since the last request.
+
+The `ts` file and the `js` file are the same thing. The `js` file displays the example in JavaScript while the `ts` file displays the example in TypeScript.
+
+Note : The methods which can be added are limited to [the supported methods](https://nodejs.org/api/http.html#http_http_methods) in the `http` module.
