Neo4j Browser visualizes all nodes + edges if you query: 'match (a:thing),(b:action) return *'
I want that node & edge data, but formatted separately, like:
{
nodes:['dog','cat','rat'],
edges:[['dog','does','bite'], ['cat','does','scratch'],['dog','chases','cat']]
}
I'm come up with a monstrous cypher query below... but it only returns (a:thing)-[r:does]-(b:action) and does not return ['dog','chases','cat'] (which would be (a:thing)-[r1:chases]-(a:thing)
Please help.. there must be an easier or more elegant way to fetch separate node/edge data?
MATCH (a:thing),(b:action)
OPTIONAL MATCH (a)-[r]-(b)
OPTIONAL MATCH (a)-[r1]-(a)
OPTIONAL MATCH (b)-[r2]-(b)
WITH
COLLECT(DISTINCT a) + COLLECT(DISTINCT b) as elcol,
COLLECT(DISTINCT r) + COLLECT(DISTINCT r1) + COLLECT(DISTINCT r2) as relcol
UNWIND elcol as ellist
UNWIND relcol as rellist
RETURN
COLLECT(DISTINCT [ellist.name, labels(ellist)]) as els,
COLLECT(DISTINCT [startnode(rellist).name, type(rellist), endnode(rellist).name]) as rels
