Question: store selected Element as State
zirkelc opened this issue · comments
I'm listening to the select
and unselect
events on nodes
and edges
and saving this as selectedElement
state:
React.useEffect(() => {
cyRef?.on('select unselect', 'node, edge', (event) => {
setSelectedElement(event.target);
});
return () => {
cyRef && cyRef.off('select unselect');
};
}, [cyRef]);
When I check the selectedElement
state on the React Dev Tools, I see that I actually store an reference to an Array:
I think the selectedElement
is type of SingularElementArgument
, so a single item collection.
I was wondering if it does make any sense to store the element reference as state:
Would a second selection of the same element give me the same object reference again?
Would it make more sense to store the element.id()
?
Are there any drawbacks when storing the element ref as state?
