I tried a simple example to run a Pluto notebook with a WGLMakie interactive plot.
When Pluto is run locally, the plots show just fine. On the other hand, if the notebook is launched on a remote machine (connection through a ssh tunnel), the plots are just blank and I get the warning

┌ Warning: Waiting for page sessions to load.
│                 This can happen for the first cells to run, or is indicative of faulty state
└ @ JSServe ~/.julia/packages/JSServe/bo3OG/src/display.jl:158

What I tried is the following (Pluto cells delimited by begin…end blocks):

begin
  using JSServe
  Page(listen_url="0.0.0.0")
end
begin
  using WGLMakie
  f(x, y) = sin(x^2+y^2)
  xs = range(-2,2; length=40)
  ys = xs
  zs = f.(xs, ys’)
  surface(xs, ys, zs)
end

Maybe I didn’t understand how to configure the server with JSServe.
Thanks for any help.

I think @koehlerson figured out a running setup?

This works for me

using JSServe
external_ip = #yourip e.g. "192.158.1.38/"
port = #somefreeport e.g. "10000"
JSServe.JSSERVE_CONFIGURATION.listen_port[] = port
JSServe.JSSERVE_CONFIGURATION.external_url[] = "http://$(external_ip)$(port)/"
JSServe.JSSERVE_CONFIGURATION.content_delivery_url[] = JSServe.JSSERVE_CONFIGURATION.external_url[]
import WGLMakie

JSServe.Page(;external_url="http://$(external_ip)$(port)/",listen_port=port, content_delivery_url=JSServe.JSSERVE_CONFIGURATION.external_url[])

Cool :) I'm going to leave this issue open, since this should all be handled in a reasonable way by Page or actually by better integrating with Pluto.

Which configuration do you have? For me it’s still not working. With the same configuration below, it does not even work locally.

I tried that on a fresh environment, here the Project.toml (I’m using Julia 1.6.0):

   Status `~/.../Project.toml`
  [8197267c] IntervalSets v0.5.3
  [824d6782] JSServe v1.2.2
  [c3e4b0f8] Pluto v0.14.7
  [7f904dfe] PlutoUI v0.7.9
  [276b4fcb] WGLMakie v0.3.9

What do you mean by that? That configuration can't work locally...
What did you actually try?

Sorry, I did not explain it well. I tried what @koehlerson suggested running Pluto on a remote machine and it wasn’t working, so I wanted to try again if it works locally. I tried the following.

begin
	using JSServe, WGLMakie
	Page()
end
begin
	xs = 1:100
	ys = xs
	f(x,y) = exp(x-y)*sin(x-y)
	zs = f.(xs,ys')
	surface(xs, ys, zs)
end

By the configuration I meant the environment configuration in Project.toml: I tried with the same versions of the packages both locally and remotely.

Now locally I get these errors:

Can you try locally to set a different port for JSServe or Pluto?

@nicolamos

You mean change only the listen_port, or should I provide also a different URL?
If I run Page(listen_url=1235), having Pluto on 1234, it does not work either.

How long did you actually wait for the plot to show up? These warnings should be non fatal, and it may take a while for the first plot to compile and show up...

Well I waited quite long I think. I tried now to follow one of the examples of JSServe using WGLMakie… This works fine, even if it takes a bit.

@SimonDanisch

So, do I understand it correctly that it works now?

@nicolamos

Sorry, no. I am trying different things to understand better how it works. I tried to reproduce one of the examples here, deploying an app in the browser. But, still, with Pluto no luck.

With Pluto I end up with the errors I’ve shown you and a blank output.

Can you try something super simple like:

And Pluto v0.14.7.

I just tested this and it works well:

Btw, are you on safari by any chance?
That's the only platform specific thing that comes to my mind, which could make things not turn up.

If you do that, please take note if it just stays blank but interactive (can execute Julia code), or stays blank and freezes the notebook...

Ok I tried your example and it works fine now. Thank you very much for the trouble. I don’t really know what was happening. I am using Chrome, btw.

I also tried to use Pluto remotely again and it works! The following should work fine, for real this time.

I guess you were on the wrong versions then ;)
