Subscribe/Unsubscribe

Subscribe

Use on() to subscribe, the usage is similar to addEventListener(), but is fully typed and returns the corresponding unsubscribe function.

Pointeract utilizes native EventTarget internally, the events are CustomEvents and event data is stored in e.detail.

const hook = (e: typeof pointeract.events.drag) => {
    console.log(e.detail);
};
const unsubscribe = pointeract.on('drag', hook);

Unsubscribe

Use off() or returned unsubscribe functions to unsubscribe, also similar to removeEventListener():

unsubscribe();
// or:
pointeract.off('drag', hook);

TIP

Its good practice to unsubscribe all the events before the disposal of a Pointeract instance.
