It's easy to send an event from an HTTP client to a server: just send an HTTP request. However, sending events from the server to the client requires more sophisticated approaches. Server-sent events are a standardized way of pushing events from the server to the client.
This package allows your Yesod application to easily send
server-sent events. On the client side, you may use the
or a polyfill for browsers that don't (we support Remy's
polyfill out-of-the-box, although that requires you to
explicitly support it).
