Maybe it can be compatible with non-websocket mode? Some CDNs do not allow websocket connections.

If you use long polling, you will have the following advantages:
better compatibility
The server does not have multiple sets of time.Tick
Have smaller dependencies

Another option is to use server-sent events.

good idea,use server-sent events changes much less than long polling

The server does not have multiple sets of time.Tick

Statsviz uses a single timer. How would that change with any other solution?
Unless I'm missing something you will still send stats at a given frequency, and you need a timer for that?

Can't you circumvent CDN restrictions by using a proxy?

Server side events are a solution but they're one way only iirc, which would work with the current feature set but would prevent potential features we have in mind.

When I open multiple pages, the custom indicator is called multiple times per second, which causes errors in some of my statistics. Using other solutions has nothing to do with this. Maybe I should open a separate issue.

I don't have that access.

Can you give an example? If the client needs to send data, it can be solved through a new request.

That's what I think, too.

My main reason for wanting that improvement is to avoid dependency on github.com/gorilla/websocket.

I'm thinking if the browser needs to send data to statsviz. For now it doesn't need to but SSE are a one way street (app->browser)

What custom indicator?

[mzzsfy]

What custom indicator?

userPlots
statsviz.TimeSeries.GetValue is called multiple times per second

[arl]

What custom indicator?

userPlots statsviz.TimeSeries.GetValue is called multiple times per second

Uhm ok that's not normal. Could you please open an issue for this? And post a simple reproducer if you can?

Open 2 web pages and you can see the phenomenon .
I'll create a new issue
