StippleTypedArrays

StippleTypedArrays is a Stipple plugin to integrate Javascript TypedArrays.

Typical use cases are buffers that are used, e.g. for downloading files or processing and sending information via binary channels.

StippleTypedArrays introduces an Vector wrapper TypedArray that can be used in type declarations for app variables.

Caveat:

On the backend side all handlers work as normal. However, on the client side javascript cannot watch typed arrays, so any change of the buffer on the client side will not be automatically synchronised.

If you want to sync your data to the server, you have to do it by callin this.push('data') after updating the value.

Demo App

using Stipple, Stipple.ReactiveTools

using StippleTypedArrays
using StippleDownloads

@app begin
    @in data = TypedArray(UInt8[])
    @in data64 = TypedArray(UInt64[])

    @in add_data = false
    @in clear_data = false

    @onbutton add_data begin
        x = rand(0:255)
        push!(data, x)
        notify(data)
        push!(data64, x + 1000)
        notify(data64)
    end

    @onbutton clear_data begin
        data = data64 = []
    end
end

@deps StippleTypedArrays

function ui()
    row(cell(class = "st-module q-ma-md", [
      
        row(class = "q-pa-md bg-green-2", "Data: [{{ data }}]")
        row(class = "q-pa-md q-my-lg bg-green-4", "Data64: [{{ data64 }}]")
