I was considering a simple example of a plot whose underlying model parameters are given by the output of a slider.
While it was working “before”, now the slider doesn’t seems to have effect any more on the plot and I got the error " nested task error: MethodError: no method matching isopen(::HTTP.WebSockets.WebSocket)".
This is a basic example from a 2019 forum post:
```julia
using Interact, Plots, Mux
mp = @manipulate throttle=.05 for λ=0:.1:5, μ=0:.1:5
xs = range(0.0, 1.0, length = 100)
Plots.plot(xs, x -> λ*x^2 + μ)
end
ui = dom"div"(mp)
WebIO.webio_serve(page("/", req -> ui), 8002)
```
A slighly more complex example, that I am sure it was working some time ago is instead:
```julia
using Interact,Plots,Mux
function myModel(p1,p2)
xrange = collect(-50:+50)
model = p1.*xrange .+ p2.* (xrange) .^2
return model
end
function createLayout()
p1s = slider(-50:50, label = "Par#1 (linear term):", value = 1)
p2s = slider(-5:0.1:5, label = "Par#2 (quad term):", value = 1)
mOutput = Interact.@map myModel(&p1s,&p2s)
plt = Interact.@map plot(collect(-50:50),&mOutput, label="Model output")
wdg = Widget(["p1" => p1s, "p2" => p2s], output = mOutput)
@layout! wdg hbox(plt, vbox(:p1, :p2))
end
function serveLayout(destinationPort)
try
WebIO.webio_serve(page("/", req -> createLayout()), destinationPort)
catch e
if isa(e, IOError)
# sleep and then try again
sleep(0.1)
serveLayout(destinationPort)
else
throw(e)
end
end
end
serveLayout(8001)
```
How do you do basic slider-control-a-plot web page in 2024? I have tried to look at the Genie documentation but there is a huge set of web related terminology/concepts there, including HTML tags, that I would like to avoid (while still coding the page)

Not really, because I actually consider the “plot” a detail here. Sorry I realize I put Plot is in the title…
I am looking for a way to show how can I have some parametrized model, some widget to expose the parameters to a web user, a way to run the model in the back end with such parameters and a way to expose the new output to the user… the simplest thing is a plot, so I am using this in the example, but the output could be a table or could be a file to download…
(for context, I am updating a 2019 book where I was using Plots+Mux+Interact)

Please click through the link to see how WGLMakie uses Bonito.jl to do what you would like.
Someone probably needs to find a working Manifest.toml file for the example you are trying to run.

Thank you I’ll give it a try… I feel it is an issue with either Mux or Interact. There is a similar discussion [here](https://discourse.julialang.org/t/gksqt-problem-help-needed-to-debug/106892/7)

I was able to get this to work by downgrading Mux.jl to v0.7.6 and HTTP.jl to v0.9.17.
Something seems to have been lost as HTTP.jl upgraded to version 1.0.
```julia
(interact_plot_mux) pkg> st
Status `~/julia/discourse/interact_plot_mux/Project.toml`
⌅ [cd3eb016] HTTP v0.9.17
[c601a237] Interact v0.10.5
⌃ [a975b10e] Mux v0.7.6
[91a5bcdd] Plots v1.40.5
Info Packages marked with ⌃ and ⌅ have new versions available. Those with ⌃ may be upgradable, but those with ⌅ are restricted by compatibility constraints from upgrading. To see why use `status --outdated`
```

You can try the fix by grabbing my branch:
```julia
using Pkg
Pkg.add("https://github.com/mkitti/WebIO.jl.git#mkitti-fix-mux-integration")
```
If this goes stale, please feel free to follow up by pinging me here.

While I confirm that using the Manifest you provided the example works, using the latest version with your patch I have the same error:
```julia
using Pkg
cd(@ __DIR__ )
Pkg.activate(".")
Pkg.add(["Interact","Mux","Plots"])
Pkg.add(url="https://github.com/mkitti/WebIO.jl.git#mkitti-fix-mux-integration")
using Interact, Plots, Mux
mp = @manipulate throttle=.05 for λ=0:.1:5, μ=0:.1:5
xs = range(0.0, 1.0, length = 100)
Plots.plot(xs, x -> λ*x^2 + μ)
end
ui = dom"div"(mp)
WebIO.webio_serve(page("/", req -> ui), 8003)
```

Yes I did, but I personally find it too complicated. The documentation seems to be for another target of users, not for data analysis people that want to just expose their models to the web.
I did web development long time ago, and I still find the documentation too difficult, with terminology and concepts that are very far away…

You might need to clear your compile cache for WebIO.jl. It should be under `~/.julia/compiled/v1.10/WebIO`.

done, deleted everything but still got the error arghh…
thank you any how, I will just delete that section… lots of problems also in Genie, really not as simple in Julia as in R Shiny unfortunately :-//

To be fair, R Shiny is incredible and really found a great stack that is robust. I have also been searching for such a stack in julia but not found it. I use Oxygen.jl for my APIs which works well. It’s not as mature as FastAPI but I get to stay in Julia. 🙂 I saw a few cool html generators that could be combined with Oxygen and I think it was HTMX.jl but I might be mistaken. See the following discussion [What can we learn from FastHTML? - #7 by tp2750](https://discourse.julialang.org/t/what-can-we-learn-from-fasthtml/117663/7)

The approach you are taking is not the start of the art for how to do this in Julia.
The leading methods are Pluto.jl and WGLMakie.jl:
1. [Interactivity](https://featured.plutojl.org/basic/plutoui.jl)
2. [Beautiful Makie](https://beautiful.makie.org/dev/examples/dashboards/tesseral_spherical_harmonics)
I would first delete the compiled code for WebIO, and then run the `Pkg` commands in this order. Adding by branch has to come first, otherwise the older code will get compiled and cached.
As I mentioned this is using some older technology.
```julia
using Pkg
cd(@ __DIR__ )
Pkg.activate(".")
Pkg.add(url="https://github.com/mkitti/WebIO.jl.git#mkitti-fix-mux-integration")
Pkg.add(["Interact","Mux","Plots"])
using Interact, Plots, Mux
mp = @manipulate throttle=.05 for λ=0:.1:5, μ=0:.1:5
xs = range(0.0, 1.0, length = 100)
Plots.plot(xs, x -> λ*x^2 + μ)
end
ui = dom"div"(mp)
WebIO.webio_serve(page("/", req -> ui), 8003)
```

I see. Genie was indeed first designed as a full stack web framework, but we’re making an effort to make it easier to create simple apps to interact with your models/data. I’d also suggest that you check out Genie Builder, which lets you create the UI part without having to write any code.
