## yesod-eventsource
|
|
|
|
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](http://www.w3.org/TR/eventsource/) 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
|
|
`EventSource` JavaScript object on browsers that support it
|
|
(https://developer.mozilla.org/en-US/docs/Server-sent_events/EventSource)
|
|
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).
