How to implement a React-like hook functionality?

[millken]

Hi,

I am currently working with Mithril.js and I came across an interesting feature in React that I would like to replicate. In React, we have hooks, such as useState and useEffect, which provide a convenient way to manage state and perform side effects within a functional component.

I have a specific use case where I want to replicate the functionality of the useDetails hook from React. The code snippet below demonstrates how it is used in React:

<State>
  {([]) => {
    const { getDetailsProps, open, setOpen } = useDetails({ closeOnOutsideClick: true });
    const { onToggle, ...detailsProps } = getDetailsProps();
    const customToggle = e => {
      onToggle(e);
      window.alert('hi');
    };
    return (
      <Details {...detailsProps} onToggle={customToggle}>
        <Button as="summary">{open ? 'Open' : 'Closed'}</Button>
        Hello World
      </Details>
    );
  }}
</State>

This code utilizes the useDetails hook to handle the state and functionality of a Details component. The open state value determines whether the details are open or closed, and the onToggle function is called when the details are toggled. Additionally, an alert is shown with the message “hi” when the toggle happens.

I would like to achieve a similar functionality in Mithril.js but I am not sure how to approach it. Could you please provide guidance on how I can implement a custom hook in Mithril.js to handle this use case?

Thank you in advance for your assistance!
