Uploading csv to backend to process and display results

I would like to know how can i upload a csv file through stipple to the backend for processing? Currently, I am working with the example provided by @essenciary which can display a random dataframe to the frontend. However, I want client users to upload their own csv file.

Example Script:

using Genie, Stipple
using StippleUI
using DataFrames

dt = DataFrame(rand(10,2), ["x1", "x2"])
dt_opts = DataTableOptions(columns = [Column("x1"), Column("x2", align = :right)])
# WEB_TRANSPORT = Genie.WebThreads #for AJAX/HTTP

@reactive mutable struct APP <: ReactiveModel
  data::R{DataTable} = DataTable()
  data_pagination::DataTablePagination = DataTablePagination(rows_per_page=50)       
end

function handlers(model)

  on(model.isready) do isready
    isready || return 

    model.data[] = DataTable(dt, dt_opts)
  end

  model
end

function ui(model::APP)
  page(model, 
  [
      heading("Dashboard") 
      
      row([
          cell(class="st-module", [
              h4("Dataset")
              # add your table logic here: 
              table(:data;
              pagination=:data_pagination, 
              style="height: 350px;"
              #dense=true, flat=true, 
              )
          ])
      ])
  ])
end

route("/") do
  APP |> init |> handlers |> ui |> html
end
up(9000)

Thanks would highly appreciate the help! Look forward to the suggestions.

In this discussion you can find an example of uploading a file.

It will be great if there is an example demonstrating how you can upload and process a CSV file.

For example, it will be nice to show you can upload a custom CSV file to perform k-means clustering using the example https://github.com/GenieFramework/StippleDemos/tree/master/IrisClustering but uploading . The CSV file should be uploaded using for example https://github.com/GenieFramework/StippleDemos/tree/master/BasicExamples/CsvUpload
