Send SSE

Transmit Server-Sent Events over http.

Installation

npm install send-sse

Usage

var sendSSE = require('send-sse');
var events = require('./events');

http.createServer(function (req, res) {
  sendSSE(req, res, events.onData);
}).listen(8080);

API

sendSSE(request, response, onOpen[, onClose]) -> close

Create an SSE stream on the response object, returning a close method to stop the stream.

request

Required
Type: http.ServerRequest

Request object from http.

response

Required
Type: http.ServerResponse

Response object from http to send the stream down.

onOpen

Required
Type: function (broadcast)

Method called when streaming events begins, passes in a broadcase method as the first parameter which can be used to send events on the stream.

onClose

Optional
Type: function (broadcast)

Called when the connection is closed, either from client or server, passing in the same broadcast method that onOpen receives.

Note: If onClose is not passed in, and onOpen returns a method, this method will be used as the onClose handler. This makes geval events work seamlessly.
