Process Query Results

Methods like gql() and uql() return a Response containing the raw query results from the database and execution metadata. To use the query results in your application, you need to extract and convert them into a usable data structure.

Response includes the following fields:

Extract Query Results

To extract the query results, i.e., the DataItem from Response.items, use the get() or alias() method.

get()

Extracts query results by the alias index.

Parameters

• index: number: Index of the alias.

Returns

• DataItem: The query results.

const response = await driver.gql("MATCH (n)-[e]->() RETURN n, e LIMIT 2");
console.log(response.get(0));

The GQL query returns two aliases (n, e), the get() method gets the DataItem of the alias n at index 0.

DataItem {
  alias: 'n',
  type: 2,
  entities: [
    Node {
      uuid: '6557243256474697731',
      id: 'U4',
      schema: 'User',
      values: [Object]
    },
    Node {
      uuid: '7926337543195328514',
      id: 'U2',
      schema: 'User',
      values: [Object]
    }
  ]
}

alias()

Extracts query results by the alias name.

Parameters

• alias: string: Name of the alias.

Returns

• DataItem: The query results.

const response = await driver.gql("MATCH (n)-[e]->() RETURN n, e LIMIT 2");
console.log(response.alias("e"));

The GQL query returns two aliases (n, e), the alias() method gets the DataItem of the alias e.

DataItem {
  alias: 'e',
  type: 3,
  entities: [
    Edge {
      uuid: '2',
      fromUuid: '6557243256474697731',
      toUuid: '7926337543195328514',
      from: 'U4',
      to: 'U2',
      schema: 'Follows',
      values: [Object]
    },
    Edge {
      uuid: '3',
      fromUuid: '7926337543195328514',
      toUuid: '17870285520429383683',
      from: 'U2',
      to: 'U3',
      schema: 'Follows',
      values: [Object]
    }
  ]
}

Convert Query Results

You should use a as<DataStructure>() method to convert the DataItem.entities into the corresponding data structure.

asNodes()

If a query returns nodes, you can use asNodes() to convert them into a list of Nodes.

const requestConfig: RequestConfig = { graph: "g1" };
const response = await driver.gql("MATCH (n:User) RETURN n LIMIT 2", requestConfig);
const nodes = response.alias("n").asNodes();
for (const node of nodes) {
  console.log(node)
}

Node {
  uuid: '6557243256474697731',
  id: 'U4',
  schema: 'User',
  values: { name: 'mochaeach' }
}
Node {
  uuid: '7926337543195328514',
  id: 'U2',
  schema: 'User',
  values: { name: 'Brainy' }
}

asFirstNode()

If a query returns nodes, you can use asFirstNode() to convert the first returned node into a Node.

const requestConfig: RequestConfig = { graph: "g1" };
const response = await driver.gql("MATCH (n:User) RETURN n", requestConfig);
const node = response.alias("n").asFirstNode();
console.log(node)

Node {
  uuid: '6557243256474697731',
  id: 'U4',
  schema: 'User',
  values: { name: 'mochaeach' }
}

asEdges()

If a query returns edges, you can use asEdges() to convert them into a list of Edges.

const requestConfig: RequestConfig = { graph: "g1" };
const response = await driver.gql("MATCH ()-[e]->() RETURN e LIMIT 2", requestConfig);
const edges = response.alias("e").asEdges();
for (const edge of edges) {
  console.log(edge)
}

Edge {
  uuid: '2',
  fromUuid: '6557243256474697731',
  toUuid: '7926337543195328514',
  from: 'U4',
  to: 'U2',
  schema: 'Follows',
  values: { createdOn: '2024-02-10' }
}
Edge {
  uuid: '3',
  fromUuid: '7926337543195328514',

  to: 'U3',
  schema: 'Follows',
  values: { createdOn: '2024-02-01' }
}

asFirstEdge()

If a query returns edges, you can use asFirstEdge() to convert the first returned edge into an Edge.

const requestConfig: RequestConfig = { graph: "g1" };
const response = await driver.gql("MATCH ()-[e]->() RETURN e LIMIT 2", requestConfig);
const edge = response.alias("e").asFirstEdge();
console.log(edge)

Edge {
  uuid: '2',
  fromUuid: '6557243256474697731',
  toUuid: '7926337543195328514',
  from: 'U4',
  to: 'U2',
  schema: 'Follows',
  values: { createdOn: '2024-02-10' }
}

asGraph()

If a query returns paths, you can use asGraph() to convert them into a Graph.

const requestConfig: RequestConfig = { graph: "g1" };
const response = await driver.gql("MATCH p = ()-[]->() RETURN p LIMIT 2", requestConfig);
const graph = response.alias("p").asGraph();
console.log("Unique nodes:", graph.nodes)
console.log("Unique edges:", graph.edges)
console.log("All paths:", graph.paths)

Unique nodes: Map(3) {
  '6557243256474697731' => Node {
