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 🙏

Js Scroll Effect

Why JS scroll effect?

  • Native javascript
  • Ease to use, ease to custom.
  • Lightweight and powerful.
  • Support all web browsers in pc, mobile, tablet.

Install

  $ npm install js-scroll-effect --save

Basic Usage

Native Js

<html>
  <head>
    <link rel="stylesheet" href="/dist/jse.css" />
  </head>

  <body>
    <h1 data-animation>Js scroll effect</h1>

    <script src="/dist/jse.js"></script>
    <script>
      JSE.init();
    </script>
    <body></body>
  </body>
</html>

ES6

Javascript

import JSE from 'js-scroll-effect';

window.addEventListener('DOMContentLoaded', () => {
  // init scroll effect to all page
  JSE.init();
});

Css

  @import '~/node_modules/js-scroll-effect/dist/jse.css';
  • Then you make css by yourself in your project.
  @keyframes myCustomEffect {
    from {
      opacity: 0;
      transform: translateY(50px);
    }
    to {
      opacity: 1;
      transform: translateY(0);
    }
  }
  • Then put your keyframes name to data-animation-name in your html element attribute.

  • Some default keyframes already in css file:

    • fadeIn
    • fadeInUp
    • fadeInDown
    • fadeInLeft
    • fadeInRight

Html

  <div class="container">
    <div data-animation>Default scroll effect is fadeInUp</div>
    <div data-animation data-animation-name="myCustomEffect">Use your custom effect</div>
  </div>

Custom

Javascript options

import JSE from 'js-scroll-effect';

window.addEventListener('DOMContentLoaded', () => {
  // init scroll effect to all page
  const myElements = Array.from(document.querySelectorAll('.my-element'));
  JSE.init(myElements);
});

Html data attributes

  • If you are using javascript options above so data-animation is unnecessary in your html element.

| Attribute | Default | Required | | :------------------------- | :--------: | ---------: | | data-animation | | required | | data-animation-name | fadeInUp | optional | | data-animation-duration | 500ms | optional | | data-animation-delay | 300ms | optional | | data-animation-fill-mode | forwards | optional |

  • Examples
  <div class="container">
    <h1 data-animation data-animation-name="myCustomEffect" data-animation-duration="1000ms" data-animation-delay="500ms">Use data attributes to control your effect</h1>
  </div>
