struct Dash <: Any

Representation of Dash application

@callid_str"

Macro for crating Dash CallbackId. Parse string in form "[{State1[, ...]}] Input1[, ...] => Output1[, ...]"

#Examples

    id1 = callid"{inputDiv.children} input.value => output1.value, output2.value"

callback!(func::Function, app::Dash, id::CallbackId; pass_changed_props = false)

Create a callback that updates the output by calling function func.

If pass_changed_props is true then the first argument of callback is an array of changed properties

Examples

app = Dash("Test") do
    html_div() do
        dcc_input(id="graphTitle", value="Let's Dance!", type = "text"),
        dcc_input(id="graphTitle2", value="Let's Dance!", type = "text"),
        html_div(id="outputID"),
        html_div(id="outputID2")

    end
end
callback!(app, CallbackId(
    state = [(:graphTitle, :type)],
    input = [(:graphTitle, :value)],
    output = [(:outputID, :children), (:outputID2, :children)]
    )
    ) do stateType, inputValue
    return (stateType * "..." * inputValue, inputValue)
end

You can use macro callid string macro for make CallbackId :

callback!(app, callid"{graphTitle.type} graphTitle.value => outputID.children, outputID2.children") do stateType, inputValue

    return (stateType * "..." * inputValue, inputValue)
end

Using changed_props

callback!(app, callid"graphTitle.value, graphTitle2.value => outputID.children", pass_changed_props = true) do changed, input1, input2
    if "graphTitle.value" in changed
        return input1
    else
        return input2
    end
end

make_handler(app::Dash; debug = false)

Make handler for routing Dash application in HTTP package

#Arguments

• app::Dash - Dash application
• debug::Bool = false - Enable/disable all the dev tools

#Examples

julia> app = Dash("Test") do
    html_div() do
        html_h1("Test Dashboard")
    end
end
julia> handler = make_handler(app)
julia> HTTP.serve(handler, HTTP.Sockets.localhost, 8080)
