Code Sample

Below is a simple example that connects to a local memgraph instance and creates and then retrieves a simple graph. See Getting started with Memgraph on how to get this running.

 // Connect to the local memgraph instance
let connectParams = ConnectParams(host: "localhost", lazy: false)
let connection = try Connection.connect(params: connectParams)

// Create simple graph.
try connection.executeWithoutResults(query: """
                                            CREATE (p1:Person {name: 'Alice'})-[l1:Likes]->(m:Software {name: 'Memgraph'})
                                            CREATE (p2:Person {name: 'John'})-[l2:Likes]->(m)
                                            CREATE (p3:Person {name: 'Peter'})-[l3:Likes]->(x:Software {name: 'Neo4j'});
                                            """
)

// Fetch the graph.
let columns = try connection.execute(query: "MATCH (n)-[r]->(m) RETURN n, r, m;", params: nil)
print("Columns: \(columns.joined(separator: ", "))")

for record in try connection.fetchall() {
    for value in record.values {
        switch value {
        case .node(let node):
            print("\(node)")
        case .relationship(let edge):
            print("-\(edge)-")
        default:
            print("\(value)")
        }
    }
}
