data-net

Serializable (JSON.stringifiable) graph (nodes connected by edges). Multiple connections between the same nodes are possible.

Graph is a set of Nodes connected by Edges:

  Graph                Node              Edge
  .nodes[]             .data             .from
  .get edges[]         .edges[]          .to

  .node()              .remove()         .remove()
  .edge()

  .toJSON()            .toJSON()         .toJSON()
  .create(json)

  .fromJSON(json)      .id               .id
                       .graph            .graph

Examples

Graph serialization/deserialization

This example creates a "triangular" graph (3 nodes, 3 edges).

  const { Graph } = require('data-net')

  let g = Graph.create()
  let n1 = g.node('node1 data')
  let n2 = g.node({name: 'John', age: 24})
  let e1 = g.edge(n1, n2)
  let n3 = g.node(666)
  let e2 = g.edge(n2, n3, 'edge data')
  let e3 = g.edge(n3, n1)

  let sg = JSON.stringify(g)
  console.log(sg)

  let g2 = Graph.create(sg)

console output:

  {
    "nodes": [
      {
        "id": "7470b312c0465758",
        "data": "node1 data"
