Provide destroy method

Feature request

I can subscribe on some events inside module, but I can’t unsubscribe with current API

For example, crosstab module subscribes on storage event and this logic will work whole page lifecycle, and I don’t have mechanism to stop it.

Hi, I think this is responsibility of module author to allows “destroy” module. We can imagine multiple different scenarios where the store have to support destroy but only partially, so covering them all from the storeon top level will be hard and will requires changes of api. In my project I’m using such pattern for modals:

let modalModule = store =>
    store.on('openModal', () => {
           const destroy = [
                store.on('confirm', ...
                store.on('help', ...
                store.on('closeModal',() => destroy.forEach(i => i())]
    }

Example on @jeetiss code: or

I realize that I can wrap over createStore function and create destroy method without modifying core logic

Do you need to use Storeon plugins or you write your own? If you have only own modules, this way will work for you.

If you need a “destroy” support in standard plugins, we need something like @destroy event (but still it will be awesome to move it to some submodule, since it is rare feature).
