forEachNode

function Graph.forEachNode(
    graph: Graph,
    type: NodeType,
    fn: (node: Node) => void,
): Graph

Iterates over all nodes of a specific type, executing a function for each node. Returns the graph unchanged (for chaining).

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>();
let g = Graph.setNode(graph, { type: "Task", id: "1", title: "First Task" });
g = Graph.setNode(g, { type: "Task", id: "2", title: "Second Task" });
g = Graph.setNode(g, { type: "Task", id: "3", title: "Third Task" });

Graph.forEachNode(g, "Task", (task) => {
    console.log(task.title);
});
// Logs:
// "First Task"
// "Second Task"
// "Third Task"
