server-sent-events v1.0.1

server-sent-events

Express middleware to push events/messages from the server to the browser, using EventSource.

This middleware will keep the request stream open indefinitely, pad the initial response stream for IE and flush the response if the compression middleware is in use.

Detailed information on how to setup the browser/client can be found here.

Installation

$ npm install -g server-sent-events

Usage (with express)

// require sse
var sse = require('server-sent-events');
var express = require('express');

var app = express();

app.get('/events', sse, function(req, res) {
	// res.sse is made available via the middleware
	res.sse('data: im from the server\n\n');
});
