# actix-web-sse-broadcast-from-thread

This project is based on the [server-sent-events example of actix-web](https://github.com/actix/examples/tree/master/server-sent-events).

Instead of posting a message to an endpoint to be broadcasted, this project supports a thread from `actix_web::rt::spawn` which broadcasts messages every 200ms, messages which end up sent as server-sent-events.

Use cases could be:

- show the stock-exchange price in real-time

- multiplayer game: sending updates in real time

- ...

### Features

It is interruptible via Ctrl+C (it is necessary to handle `Arc` in threads).

## Run

```sh

cargo run

# go to http://localhost:8080/

```
