How to write a GraphQL query from the cypher example using bounding box?

Neo4j Graph Platform Cypher
1

Can someone please show me how to write a graphQL query from this cypher?

MATCH (n:MyNode)

WHERE n.location.latitude > 40.8 AND n.location.latitude <41.5

AND n.location.longitude > -8.7 AND n.location.longitude < -6.8

RETURN n

Rather than using location_LT, I want to be able to use latitude_LT/GT and longitude_LT/GT to constrain the search for nodes based on a bounding box.

Thanks!

Do you mean Neo4J's GraphQL ?

You can use the toolbox?

I will explore the toolbox thank you!

To clarify a little, I've built a GraphQL API (my first), to provide a user-friendly access to a Neo4j Knowledge Graph instance. The part in the GraphQL schema I'm interested in adapting looks like this:

  type MyNode @node {
    Id: String!
    location: Point!
}

  input MyNodeWhere {
    Id: String
    location: PointWhere
    location_LT: PointDistance
    location_GT: PointDistance
    AND: [MyNodeWhere!]
    OR: [MyNodeWhere!]
    NOT: MyNodeWhere
  }
  
  input PointWhere {
    latitude: Float
    longitude: Float
    latitude_LT: Float
    longitude_LT: Float
    latitude_GT: Float
    longitude_GT: Float
    crs: String
  }

But it seems my approach to defining PointWhere is wrong, I'm not sure why.

Any errors you could share?

I recommend you connect to your Neo4j DB using our GraphQL Toolbox

This will

  • Generate Type Definitions using introspection on your Neo4j DB
  • Allow you create queries / mutations using a 'point and click' approach

Please do let us know how you get on and post the Type Defs from the Toolbox back here if you need further assistance
