WebSockets starter for Rust

Implements WebSocket passthrough.

Platform:
Compute@Edge
Language:
Rust
Repo:
https://github.com/fastly/compute-starter-kit-rust-websockets

Use this starter

Using the Fastly CLI, create a new project using this starter somewhere on your computer:

$ fastly compute init --from=https://github.com/fastly/compute-starter-kit-rust-websockets

Or click the button below to create a GitHub repository, provision a Fastly service, and set up continuous deployment:

Deploy to Fastly

Setup

The app expects a configured backend named backend that points to a WebSocket server. For example, if the WebSocket server is available at domain websockets.example.com, then you'll need to create a backend on your Compute@Edge service named backend with the destination host set to websockets.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 to the backend.

Note

This app is not currently supported in Fastly's local development server, as the development server does not support WebSockets features. To experiment with WebSockets, you will need to publish this project to your Fastly Compute@Edge service, using the fastly compute publish command.
