Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Data Tree

Data oriented tree structure that unleashes the power of callbacks to create, search and traverse tree. Data tree keeps the track of current node which updates upon insertion and deletion of the node from tree.

Install:

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

Examples:

Following examples will guide you to create tree, insert/remove nodes and search/traverse a tree. Don't forget to checkout 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());
});

Find common parent

var commonParent = tree.findCommonParent(fromNode, toNode);

  1. Clone this repositoy and cd into it
  2. npm install
  3. npm run build to build browserify files OR npm run dev-server to start a development server.
