How to use mongo commands in escher.jl?

[n-raghu]

Hi, I have created below sample code to display mongo collection in browser but could not succeed. Can someone identify where am I doing wrong?

import Escher: @api, render
using Mongo,LibBSON, FactCheck

cli = MongoClient("mongodb://localhost:64116")
org = MongoCollection(cli, "FFC", "Org")
stack = find(org, Dict())

app = 
for doc in stack
  println(doc)
end

main(window) = begin
    push!(window.assets, "layout2")
    push!(window.assets, "icons")
    push!(window.assets, "widgets")

    t, p = wire(tabs([hbox(icon("home"), hskip(1em), "Home"),
                      hbox(icon("info-outline"), hskip(1em),  "Notifications"),
                      hbox(icon("info"), hskip(1em), "About")]),
                pages([app, "NO Notifications", "About"]), :tabschannel, :selected)

    vbox(toolbar(["FFC", flex(), iconbutton("face")]),
         maxwidth(116em, t),
         Escher.pad(1em, p))
end

edit: formatting

What should app be? in your case it will be nothing because a for loop always returns nothing. You might want to use join(map(string, stack), "\n") instead.

You don't need import Escher: @api, render or using FactCheck

Thank you, shashi, it works. Even though, we use "\n", I don't see a carriage return applied, all the docs get piled up. Any work around for this?

vbox(map(string, stack)) should do it. Or vbox(intersperse(vskip(1em), map(string, stack))) to give some space between them.

perfect vbox(map(string, stack)) works for me. Thanks for the quick solution.
