Data-Tree by cchandurkar

Install:

$ npm install data-tree

Then use via require('data-tree') OR use browserified build available at dataTree.min.js in <script/> tag.

Examples:

Following examples will guide you about how to create tree, insert/remove nodes and search/traverse a tree. Don't forget to check Data-Tree reference.

Create tree

dataTree is global variable that can be used to create a tree in following way.

  var tree = dataTree.create();

Insert data

// Insert single value
tree.insert(183);

// Insert array of values
// NOTE: This does not create 3 different nodes. It considers an array as a whole data and puts in a single node.
tree.insert([34, 565, 78]);

// Insert Objects
tree.insert({
  key: '#berries',
  value: { name: 'Apple', color: 'Red'}
});

Create and append node to a parent node that satisfies the given criteria

// Insert data
tree.insert({
  key: '#apple',
  value: { name: 'Apple', color: 'Red'}
});

// New Data
var greenApple = {
  key: '#greenapple',
  value: { name: 'Green Apple', color: 'Green' }
};

// Insert data to node which has `key` = #apple
tree.insertTo(function(data){
  return data.key === '#apple'
}, greenApple);

Create and append node using parent node's instance

// Insert data
var node = tree.insert({
  key: '#apple',
  value: { name: 'Apple', color: 'Red'}
});

// New Data
var greenApple = {
 key: '#greenapple',
 value: { name: 'Green Apple', color: 'Green' }
};

// Insert data to node
// This will create a new node with given data and append to parent node provided
tree.insertToNode(node, greenApple);

Remove Node

// Insert Node
var node = tree.insert({
  key: '#apple',
  value: { name: 'Apple', color: 'Red'}
});

// Remove it
tree.remove(node);

Search BFS

var node = tree.traverser().searchBFS(function(data){
  return data.key === '#apple';
});

Search DFS

var node = tree.traverser().searchDFS(function(data){
  return data.key === '#apple';
});

Traverse BFS

tree.traverser().traverseBFS(function(node){
  console.log(node.data());
});

Traverse DFS

tree.traverser().traverseDFS(function(node){
  console.log(node.data());
});
