Request Handlers
Last modified: March 28, 2025
Introduction
Communication between the Mendix client and the runtime server happens through various different request handlers.
Standard Request Handlers
The following standard request handlers are used:
| Name | Endpoint | Description |
|---|---|---|
| Resources | / | Serves static files, such as the index.html. |
| XAS | /xas | Handles the client/runtime communication. See Communication Patterns in the Mendix Runtime for more information. |
| File | /file | Handles file uploads and downloads from the Mendix client. |
| Page/Microflow URLs | /p (default) | Handles opening pages and executing microflows that have a URL configured. The endpoint can be configured in the app settings. |
| PWA Manifest | /manifest.webmanifest | Serves the manifest file that is required for PWA applications. |
| Mx Dev Tools | /mxdevtools | Websocket endpoint that handles client logs and nanoflow debugging. Only enabled during development. |
Custom Request Handlers
Custom request handlers can be added using the com.mendix.core.Core#addRequestHandler({name of the request handler}) API call.
