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 🙏

Demo

Installation

Using npm

$ npm install moveto --save

Using Yarn

$ yarn add moveto

Usage

const moveTo = new MoveTo();

const target = document.getElementById('target');

moveTo.move(target);

// Or register a trigger

const trigger = document.getElementsByClassName('js-trigger')[0];

moveTo.registerTrigger(trigger);

Trigger HTML markup

You can pass all options as data attributes with the mt prefix. Option name should be written in kebab case format, for example:

<a href="#target" class="js-trigger" data-mt-duration="300">Trigger</a>

<!-- Or -->

<button type="button" class="js-trigger" data-target="#target" data-mt-duration="300">Trigger</button>

Options

The following options are available:

new MoveTo({
  tolerance: 0,
  duration: 800,
  easing: 'easeOutQuart',
  container: window
})

| Option | Default | Description | |-----------|--------------|--------------------------------------------------------------------------------------| | tolerance | 0 | The tolerance of the target to be scrolled, can be negative or positive | | duration | 800 | Duration of scrolling, in milliseconds | | easing | easeOutQuart | Ease function name | | container | window | The container been computed and scrolled | callback | noop | The function to be run after scrolling complete. Target passes as the first argument |

API

move(target, options)

Start scroll animation from current position to the anchor point.

target

Type: HTMLElement|Number

Target element/position to be scrolled. Target position is the scrolling distance. It must be negative if the upward movement is desired.

options

Type: Object

Pass custom options.

registerTrigger(trigger, callback)

trigger

Type: HTMLElement

This is the trigger element for starting to scroll when on click.

callback

This is the callback function to be ran after the scroll completes. This will overwrite the callback option.

addEaseFunction(name, fn)

Adds custom ease function.

name

Type: String

Ease function name.

fn

Type: Function

Ease function. See Easing Equations for more ease functions.

Examples

document.addEventListener('DOMContentLoaded', function () {
  const easeFunctions = {
    easeInQuad: function (t, b, c, d) {
      t /= d;
      return c * t * t + b;
    },
    easeOutQuad: function (t, b, c, d) {
      t /= d;
      return -c * t* (t - 2) + b;
    }
  }

  const moveTo = new MoveTo({
    duration: 1000,
    easing: 'easeInQuad'
  }, easeFunctions);

  const trigger = document.getElementsByClassName('js-trigger')[0];

  moveTo.registerTrigger(trigger);
});
document.addEventListener('DOMContentLoaded', function () {
  const moveTo = new MoveTo({
    duration: 1000,
    callback: function (target) {
      // This will run if there is no overwrite
    }
  });

  const trigger = document.getElementsByClassName('js-trigger')[0];

  moveTo.registerTrigger(trigger, function (target) {
    // Overwrites global callback
  });

  // Or

  moveTo.move(1200, {
    duration: 500,
    callback: function () {
      // Overwrites global callback
    }
  });
});
document.addEventListener('DOMContentLoaded', function () {
  const moveTo = new MoveTo();

  const trigger = document.getElementsByClassName('js-trigger')[0];

  // Register a trigger
  const unregister = moveTo.registerTrigger(trigger, { duration: 500 });

  // Unregister a trigger
  unregister();
});
document.addEventListener('DOMContentLoaded', function () {
  const moveTo = new MoveTo();
  const triggers = document.getElementsByClassName('js-back-to-top');

  for (var i = 0; triggers.length < i; i++) {
    moveTo.registerTrigger(triggers[i]);
  }
});
<a href="#" class="js-back-to-top" data-mt-duration="300">Back to top!</a>
