Server-Sent Events (EventSource)
Enables push notifications from the server received as DOM events.
Fumio Sagawa commented
Have the server send and write useless programs by polling. Key features in Web applications.
These big doors called SSE need to be open quickly, there is not much to consider. SignalR is a workaround but still just a workaround to functionality that competition already have.

Pretty surprised that Microsoft Edge still does not support SSE. :/ Any updates on when this is going to roll out?
This would be hugely useful. Supported by all other browsers!
SSE is a really nice technology that all modern browsers should support! I expect the promising Microsoft Edge to support SSE and give developers the chance to build cross-browser real-time web apps.

Hello, I just realize that even Edge does not support server-sent events, which is a very useful feature of standard HTML5, I find that unbelievable in 2015 !
Come on Microsoft guys ! Implement it now ! At least in Edge ! (IE 11 also ?)
At this time we tell ALL our customers to switch either to Firefox or to Chrome in order to have a modern UI ... What a pity, that's part of what should be the standard ! Stop being behind the competition !

SSE should be implemented in Microsoft Edge, it is a nice functionality very useful for business. In my current project we make use of it, and should be nice to add IE to our supported Browsers.
Frédéric Zanaroli commented
This is a must.
Modern browsers support it.
You cannot be on the edge and being left behind :

Also the polyfill needs to use XDomainRequest, and not ordinary XHR, and that is really ugly and needs a special not standard solutions on the server side (missing header support and no cookies are send).
So, please consider proper SSE support, at least in edge !
I ditched Websockets in my app because they were not reliable and just too much for my app and replaced them with SSE. I installed Windows 10 and opened my app in Ms Edge and had found that there are no EventSource object. I'm very dissapointed
SSE is extremely important for many business use cases. Currently, we have to resort to polyfills, but would definitely like to see native support for SSE in Edge.
Please add support for SSE! Otherwise Edge will be a superhero on crutches (that is, it needs polyfils to work properly).
Please add SSE support: a lot of our applications use SSE and my company is telling to all clients to use other browsers.
Put all 25 my votes on this!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
SSE the only thing that will help developers on shared hosting actually still be able to build great apps without long polling , something so simple can allow people who do not have vps' and fancy servers to still enhance their dev experience and user experience.

we had built http://phwa.be using eventsource because it is far much stable than websocket in bad connection environment and for an interactive , responsive web app like chatrooms, websocket is overkill.
On our tests , Evensource is pure winner in
- High latency environment
- Ease of Development and maintenance (Evensource implementation in python/tornado is only 10 lines of code , from scratch)
So SSE is very important for Interactive web.

Web apps are more ubiquitous in business settings and our hospital (along with most others) are abandoning IE in favour of "more supported" browsers. Web developers are trying to leverage as many different techniques and protocols to allow data to flow from one application to the next and IE just doesn't cut it in a business setting.
Add SSE to Edge before we are forced to install Firefox on all 3,500+ PCs.
Our web site streams Stock Market Data for Investors. Our software is totally dependent on this feature. We want to include The Edge Browser in our list of compatible browsers. Please add it !!! Thanks.

This feature is definitely a good one. It does not run into issues on the transport layer like websockets sometimes does because of proxies which do not support websockets.
Would appreciate to see this to become part of the next version MS Edge.
Ivan Borisenko commented
This feature is most simpler for realtime notifications than WebSockets and is designed more throughly. All support it.
