I have general questions about how callbacks work. As per examples on Plotly website, a common convention (or maybe correct way) of writing callbacks looks like this: @app.callback( Output('graph-with-slider', 'figure'), Input('year-slider', 'value')) def update_figure(selected_year): f…

HI @parvizalizada as far as I know, the decorator expects a def statement so what you propose won’t work. You could wrap your imported function. I did something like this in the past. It’s maybe not the best way to do it, but it works @app.callback( Output(...), Input(...) ) def up…

@AIMPED , thanks for your answers. Regarding the second point, I wanted to avoid defining functions explicitly (i.e., def some_function:). But if it is the way callbacks work, the code will still look complicated, keeping all these defs in one file and having many callbacks.

hi @parvizalizada , You can define your callback without decorations. Just like this, app.callback()(your_func) Or app.callback()(lambda x: your_func(x))

hi @stu I’m not sure if I understand. Do you mean this is the syntax: import functions app.callback()(functions.function1())

no, don’t pass in the instance, just pointer. import functions app.callback()(functions.function1)

Hi there, I’m aware that I’m reviving an old topic, but I rarely see this syntax being used. [image] stu: app.callback()(your_func) With more compex callbacks or bigger apps, it could be convenient to group certain functions into different modules to help with code readibility. So my quest…

hi bro, In fact, this does not break away from using decorators, it just takes away the sugar ‘@’. The real decorator name is wrap_func, and the parameters it passes in and returns are function pointers. That’s why you can see two pairs of brackets together. I usually use this syntax when I need a …

[image] stu: write some arrow functions to a client callback. Thanks for your answer. What are your referring to with this ^^ ?
