Hi there! I followed “Realtime Data Update with NodeJS and WebSockets” for live data refresh.
Now, it works perfectly inside Wappler, it shows the data update in realtime when I add a record from another page, but when I load it in the browser it gives some errors.
I’m using Wappler 4.0.1 with Nodejs + Postgres + Docker Desktop
Please bear with me as I don’t have any experience with this 
.
Can anyone explain me what to do / change / configure? Thanks in advance!
Hello,
Are you sure you have deployed your project? Seems like some file is missing.
Hi Teodor, yes I did, just now did it again but it doesn’t work.
On the Wappler preview mode all works perfectly
Can you send a link to your page where we can check this?
It’s on localhost with the docker desktop. Is that the problem then? do I need special hosting to make websocket work?
No, you only need Nodejs server model, which you are using already.
Update: It works now.
I changed, updated, saved a lot of things so I don’t really know what was the problem / fix though
