    Library to load graph from simple json format

    Build Status

    usage

    // JSON string can be produced by `ngraph.tojson` library
    // https://github.com/anvaka/ngraph.tojson
    var jsonString = ' {"nodes":[{"id":"hello"},{"id":"world"}],"links":[{"fromId":"hello","toId":"world"}]}'
    
    var fromJSON = require('ngraph.fromjson');
    var graph = fromJSON(jsonString)
    
    graph.getNode('hello'); // returns a node;
    graph.getLinksCount(); // 1

    You can also provide custom transform functions for deserializer:

    var jsonString = {
      "nodes":[[1,"Custom data"],[2,null]],"links":[[1,2,"Custom link data"]]
      };
    
    var fromJSON = require('ngraph.fromjson');
    // each element in the input json array is an array. Provide custom transformers
    // to parse arrays:
    var graph = fromJSON(jsonString,
      function nodeLoadTransform(node) {
        return { id: node[0], data: node[1] };
      },
      function linkLoadTransform(link) {
        return { fromId: link[0], toId: link[1], data: link[2] };
      });
    
    graph.getNode(1); // returns a node, and its data is set to "Custom Data";
    graph.hasLink(1, 2); // Returns link, and its data is set to "Custom link data"
