2024-01-09 - Frontend GraphNav requesting relNodes

Frontend SitePage Element - GraphNavigation

graphNavigation useRef

• graphNavigation has Ref focusedNodes that stores array of focused nodes for each graphNav
• graphNavigation has Ref for all nodes sent relNode request to backend (so not double up requests)

initialNodes processing

• initialNodes sets focusedNodes for each graphNav as all initialNodes shown in that graphNav (objTypes)
• initialNodes setGraphNode(s)
• setGraphNode triggers a useEffect that newNodeAdded

newNodeAdded useEffect

• check ref if already sent request to backend?

for each GraphNav start

• check this node shown in that graphNav (objTypes)
• find shortest # hops to newNode from all focusedNodes
• if shortest hops is < graphNav hopLimit, need to request backend

for each GraphNav end

if any graphNav need to request backend

• check ref if already sent request to backend again, in case updated during processing (?)
• add to sent request ref
• send request

after get backend result

for each relNode

• setGraphRelationship
• setGraphNode (must do after setGraphRelationship)
• setGraphNode triggers a useEffect that newNodeAdded

for each GraphNav start

• check this node shown in graphNav (objTypes)
• check this relationship Type shown in graphNav
• find shortest # hops to newNode from all focusedNodes
• if shortest hops is < graphNav hopLimit, setGraphRelationshipPerGraphNav and setGraphNodePerGraphNav

for each GraphNav end for each relNode end
