Example that uses an external trigger

[andersr]

Hi, this packages looks very interesting but it's not clear how I would trigger an event from outside the resource route. All the current examples are "self-triggering" ie just using an interval timer. How would I, for example, trigger a new event if something is created in a form in the action of a different route? Thanks for any insights!

Hi @andersr

This is something that I actually came upon myself recently. I have not yet added an example to the repo, but let me have a play around and see how it would work with remix-sse

Ok @andersr

So to answer your question, firstly because Server Sent Events are unidirectional - we cannot send data to the streaming route to say "hey start sending events"

So with that in mind, the solution is as follows

• An action route which receives your form data and stores it somewhere
• A SSE resource route which reads this stored data again and streams events accordingly

If you need more communication than this, then I would recommend a Websocket instead

Heres a quick PR I made that adds an example to the repo

Let me know if you have any other questions!

Have a nice day :)

@dan-cooke thanks so much for looking into this and for posting an example. Yes, using a session store as the "connector" between a non-resource route and the SSE route makes a lot of sense. Going to give that a shot. Thanks again!

Closing this in the meantime!
