Searching for eventsource

UPDATE: With some serious modification to the server end point, Luke Morton was able to achieve a single open event that fires message events as responses are received via a “push” from the server: https://gist.github.com/1002722.

For those of you curious about what can be created or where to use the new JavaScript EventSource API (also known as “Server Sent Events” ) – I’ve developed a very basic chat application that uses jQuery.EventSource.js to provide a simple API to native EventSource where available (and a fallback when not) and Twitter @anywhere […]

…Not natively… but this will work in the meantime: Git it here firefox-event-source.js ;(function (w) { if ( !w[‘EventSource’] ) { // parseUri 1.2.2 // (c) Steven Levithan <stevenlevithan.com> // MIT License var parseUri = function(str) { var o = { key: [‘source’,’protocol’,’authority’,’userInfo’,’user’,’password’,’host’,’port’,’relative’,’path’,’directory’,’file’,’query’,’anchor’], q: { name: ‘queryKey’, parser: /(?:^|&amp;)([^&amp;=]*)=?([^&amp;]*)/g }, parser: { strict: /^(?:([^:\/?#]+):)?(?:\/\/((?:(([^:@]*)(?::([^:@]*))?)?@)?([^:\/?#]*)(?::(\d*))?))?((((?:[^?#\/]*\/)*)([^?#]*))(?:\?([^#]*))?(?:#(.*))?)/ } […]

This is mighty awesome. I’ve put together some test demos, to run them you’ll first need to get this Chromium build: 47357 WIN32 47357 MAC 47357 32-Bit Linux 47357 32-Bit Linux Then download these: https://gist.github.com/415116 client.html <script src=”event-source.js”></script>; event-source.js document.addEventListener(‘DOMContentLoaded’, function () { var eventSrc = new EventSource(‘events.php’); eventSrc.addEventListener(‘open’, function (event) { console.log(event.type); }); eventSrc.addEventListener(‘message’, […]

The test showed up on my desk just like any other. There I was, working with Google’s Web Platform Predictability team to find so-called “flaky” tests in the venerable Web Platform Tests project. I’d run a hundred or so at a time, over and over again, looking for any that reported inconsistent results. It was […]
