express-sse-stream v0.0.1

express-sse-stream

Middleware for express providing writeable SSE streams.

Use

To use express-sse-stream, first install it from npm: npm install express-sse-stream.

First, you'll want to require the library:

var sse = require('express-sse-stream').sse

Then, to actually create an SSE stream, install it as middleware on whatever routes you want:

app.get('/stream', sse(), function(req, res) {
	// req.sse contains the SSE stream information
	//        .stream is a node object stream you can push SSE data to
	//        .lastEventId is the last event ID specified by the browser, if applicable
	function sendTime() {
		var time = new Date().toLocaleString()
		req.sse.stream.write({ data: time })
	}

	var sender = setInterval(sendTime, 1000)

	req.sse.stream.on 'finish', function() {
		clearInterval(sender)
	}
})

Simple as that!
