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 🙏

textureactives

// ~~~~~~~~~~~~~~~~~~~~~~~
// ZIM

const panel = new TextureActive({
    width:W,
    height:H,
    color:light,
    corner:20
}).addTo();

// pressing the ALT T key will toggle between the 3D and 2D mode
// Usually we would use this during production then turn it off
// Here we add a logo that will also toggle when pressed	
TextureActive.makeLogo("light", true).loc(50,50,panel).tap(()=>{
  textureActives.manager.toggle();
});

new Circle(100, purple)
  .center(panel)
  .drag();    


// ~~~~~~~~~~~~~~~~~~~~~~~
// THREEJS

const three = new Three({
  width:window.innerWidth, 
  height:window.innerHeight, 
  cameraPosition:new THREE.Vector3(0,0,500),
  textureActive:true
});

const renderer = three.renderer;
const scene = three.scene;
const camera = three.camera;
const canvas = three.canvas;
const controls = new OrbitControls(camera, canvas);

// TEXTUREACTIVES
const textureActives = new TextureActives(panel, THREE, three, renderer, scene, camera, controls);

// if the object is a plane then we can use the makePanel
const canvasWindow = three.makePanel({
  textureActive:panel, 
  textureActives:textureActives, 
  curve:50,
  doubleSide:true
})
scene.add(canvasWindow);   

Here are the specific imports if desired:

import { Frame, Circle, TextureActive, TextureActives } from "zimjs"
// ~~~~~~~~~~~~~~~~~~~~~~~
// ZIM

const paper = new TextureActive({
	width:500,
	height:500,
	color:black,
	corner:0,
	borderColor:white,
	borderWidth:2,
	backingOrbit:false
});

const pen = new Pen({color:series(white,purple), size:10, cache:false}).center(paper);
new MotionController({target:pen, type:"pressmove", container:paper});


// ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
// THREEJS

const three = new Three({
	width:window.innerWidth, 
	height:window.innerHeight, 
	cameraPosition:new THREE.Vector3(0,0,500),
	textureActive:true
});

const renderer = three.renderer;
const scene = three.scene;
const camera = three.camera;
const canvas = three.canvas;
const controls = new OrbitControls(camera, canvas);

// TEXTUREACTIVES
const textureActives = new TextureActives(paper, THREE, three, renderer, scene, camera, controls);


// if the object is not a plane then we use the CanvasTexture
const cubeGeometry = new THREE.BoxGeometry(300,300,300);
const cubeTexture = new THREE.CanvasTexture(paper.canvas);
const cubeMaterial = new THREE.MeshBasicMaterial({map:cubeTexture});
const cube = new THREE.Mesh(cubeGeometry, cubeMaterial);           
scene.add(cube); 
textureActives.addMesh(cube);

Here are the specific imports for the example above if desired:

import { Frame, MotionController, TextureActive, TextureActives, series, Pen } from "zimjs"
import zim from "https://zimjs.org/cdn/016/zim_three";
import zim from "zimjs"
import * as THREE from "three" 
import { OrbitControls } from "three/examples/jsm/controls/OrbitControls.js"
import { Three } from "@zimjs/three"
