event-source-stream

EventSource implemented in node as a readable stream

npm install event-source-stream

Usage

var ess = require('event-source-stream')
 
ess('http://server-sent-events-demo.herokuapp.com/update')
  .on('data', function(data) {
    console.log('received event:', data)
  })

Per default it will retry after 3s when the connection terminates. Change this by setting the retry option

// no retries
ess('http://server-sent-events-demo.herokuapp.com/update', {retry:false}).pipe(...)
 
// retry after 10s
ess('http://server-sent-events-demo.herokuapp.com/update', {retry:10000}).pipe(...)

Browser support

It also works in the browser using browserify

var ess = require('event-source-stream') // will use EventSource behind the scene
 
ess('http://server-sent-events-demo.herokuapp.com/update')
  .on('data', function(data) {
    console.log('recevied event in the browser', data)
  })
