fromJS

function Graph.fromJS(data: {
    nodes: Node[];
    edges: [NodeType, NodeId, NodeType, NodeId, EdgeData][];
}): Graph

Creates a graph from a plain JavaScript object representation. Useful for deserializing graphs from JSON or other storage formats.

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 data = {
    nodes: [
        { type: "Project", id: "1" },
        { type: "Task", id: "1", title: "My Task" },
        { type: "Task", id: "2", title: "Another Task" },
    ],
    edges: [
        ["Project", "1", "Task", "1", undefined],
        ["Project", "1", "Task", "2", undefined],
    ],
};

const graph = Graph.fromJS<Nodes, Edges>(data);

Graph.hasNode(graph, ["Project", "1"]); // true
Graph.hasEdge(graph, ["Project", "1"], ["Task", "1"]); // true
