Hi <a href="https://app.daily.dev/kubeden" data-mention-id="z5gqV71Rc" data-mention-username="kubeden">@kubeden</a>,
i’m new with express and i’m trying to follow the tutorial,
I think there is an error with this:
app.use(express.static(public path));
instead i try with this and it works correctly
app.use(express.static(publicPath));
if I click on the github link in the “Setting up the front-end” part, i have an 404 error

I had to create a chat application using Angular and Spring Boot with Mongodb. I implemented a WebSocket for it and it’s not working as expected. And also I haven’t found any solution yet. I appreciate it if someone could mention a proper article, blog, or something.
Most WebSocket libraries support Node.js but fail to work properly with Java😕
