eventsource 0.1.0+2

A client and server implementation of Server-Sent Events.

eventsource

A library for using EventSource or Server-Sent Events (SSE). Both client and server functionality is provided.

This library implements the interface as described here.

Client usage

For more advanced usage, see the example/ directory. Creating a new EventSource client is as easy as a single call. The http package is used under the hood, so wherever this package works, this lbirary will also work. Browser usage is slightly different.

EventSource eventSource = await EventSource.connect("http://example.com/events");
// in browsers, you need to pass a http.BrowserClient:
EventSource eventSource = await EventSource.connect("http://example.com/events", 
    client: new http.BrowserClient());

Server usage

We recommend using shelf_eventsource for serving Server-Sent Events. This library provides an EventSourcePublisher that manages subscriptions, channels, encoding. We refer to documentation in the shelf_eventsource package for more information.

This library also includes a server provider for dart:io's HttpServer in io_server.dart. However, it has some issues with data flushing that are yet to be resolved, so we recommend using shelf instead.
