Learn about Fastly Compute with Fanout using a basic starter that sends connections through the Fanout GRIP proxy to a backend.
For more details about this and other starter kits for Fastly Compute, see the Fastly Documentation Hub.
The app expects a configured backend named "origin" that points to an origin server. For example, if the server is available at domain example.com, then you'll need to create a backend on your Fastly Compute service named "origin" with the destination host set to example.com and port 443. Also set Override Host to the same host value.
After deploying the app and setting up the backend configuration, all connections received by the service will be passed through the Fanout proxy to the origin. If WebSocket-over-HTTP mode is enabled on your service, then client WebSocket activity will be converted into HTTP when sending to the origin.
This app is not currently supported in Fastly's local development server, as the development server does not support Fanout features. To experiment with Fanout, you will need to publish this project to your Fastly Compute service. using the fastly compute publish command.
