How to select node by className along with its edges?

[robswc]

Hey! Maybe I'm over thinking, however I'm trying to do a cy.add('node.ClassName, edge[allEdgesConnectedToThoseNodes]')

If that makes sense. I've tried variations of the above, can't seem to get it to work though :/

Thanks for any and all help!

you can do that in js
something like this (didn't run this code)

const node = cy.add({..new node params...})
node.outgoers().union(node.incomers()).doSomething()

have a look at this code I use in my project to highlight nodes and edges on hover

            cy.on('mouseover', 'node', (e) => {
                if (e.target === null) return
                if (e.target === cy) return
                e.cy.startBatch()
                const sel = e.target;
                /*
                e.cy.elements()
                    .difference(sel.outgoers()
                        .union(sel.incomers()))
                    .not(sel)
                    .addClass('semitransp');
                */
                sel.addClass('highlight')
                    .outgoers()
                    .union(sel.incomers())
                    .addClass('highlight');
                e.cy.endBatch()

            });
