The router alias HTTP [middleware]({{< ref middleware.md >}}) component allows you to convert arbitrary HTTP routes arriving to Dapr to valid Dapr API endpoints.
The router alias HTTP [middleware]({{< ref middleware.md >}}) component allows you to convert arbitrary HTTP routes arriving into Dapr to valid Dapr API endpoints.
## Component format
The router alias middleware metadata contains name/value pairs, where the name describes the HTTP route to expect, and the value describes the corresponding Dapr API the request should be sent to.
