getNode

function Graph.getNode(
    graph: Graph,
    node: [NodeType, NodeId] | { type: NodeType, id: NodeId },
): Node | undefined

Retrieves a node from the graph. Returns undefined if the node doesn't exist.

Example

import { Graph } from "@monstermann/graph";

type Nodes =
    | { type: "Task"; id: string; title: string }
    | { type: "Section"; id: string }
    | { type: "Project"; id: string };

type Edges = {
    Project: { Task: void };
    Section: { Task: void };
};

const graph = Graph.create<Nodes, Edges>();
const withNode = Graph.setNode(graph, {
    type: "Task",
    id: "1",
    title: "My Task",
});

const task = Graph.getNode(withNode, ["Task", "1"]);
// task: { type: "Task", id: "1", title: "My Task" }

const missing = Graph.getNode(withNode, ["Task", "2"]);
// missing: undefined
