Library to store graph into simple json format
npm install ngraph.tojsonLibrary to store graph into simple json format
`` javascript
var graph = require('ngraph.graph')();
graph.addLink('hello', 'world');
var toJSON = require('ngraph.tojson');
console.log(toJSON(graph));
// Produces output:
// {"nodes":[{"id":"hello"},{"id":"world"}],"links":[{"fromId":"hello","toId":"world"}]}
`
You can also provide a custom transform function to transform nodes/edges before
they are pushed to the output:
` javascript
var g = require('ngraph.graph')();
g.addNode(1, { name: 'John' });
g.addNode(2, { name: 'Jim' });
graph.addLink(1, 2, 'Father');
var json = toJSON(g,
function nodeTransform(node) {
return [node.id, node.data];
},
function linkTransform(link) {
return [link.fromId, link.toId, link.data];
});
console.log(json);
// This will produce array of arrays for nodes:
// {
// "nodes": [
// [1, {"name": "John"}],
// [2, {"name": "Jim"}]
// ],
// "links": [[1, 2, "Father"]]
// }
`
With npm do:
`
npm install ngraph.tojson
