Reactive apps

app.jl

module App
using GenieFramework
@genietools

function count_vowels(message)
sum([c ∈ ['a', 'e', 'i', 'o', 'u'] for c in lowercase(message)])
end

@app begin
@in message = ""
@out vowels = 0
@onchange message begin
vowels = count_vowels(message)
end
end
@page("/", "app.jl.html")
end

ui.jl

cell([
textfield("", :message, ),
p("Message: {{message}}"),
p("Vowel count: {{vowels}} vowels.")
])

APIs

function predict()
house = data[params(:id), 1:13]
json("MEDV" => model(house))
end

@swagger """
/api/predict/{id}:
get:
description: Predict the MEDV of a house.
parameters:
- in: path
name: id
required: true
description: Numeric ID of the house to get the prediction.

type: integer

route("/api/predict/:id::Int", predict, method=GET)

ui() = render_swagger(swagger_document)
@page("/", ui)

<ul>
   <% for_each(books) do book %>
          <li>$(book.title) by $(book.author)</li>
