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 🙏

Animation for Fitbit

This library allows you create complex animations in Fitbit apps and clockfaces.

Example

Installation

Install the library with npm i fitbit-animate

Usage

Function fitbit_animate accepts sequence of animations in form of array where each element is an object with properties:

elem: G Container containing GUI elements you want to animate

prop: groupTranform property, such as "translate" or "scale"

subprop: actual propety you want to animate, such as x or y.

from: numeric value indicating animation start such as x or y coordinate or scale

to: numeric value indicating animation end

dur: duration of animation in milliseconds

Animation sequence can include multiple different GUI elements (G Containers) and each element can animate at different speed. Function returns a promise that resolves when all animation in the sequence are finished.

resources/index.gui

    <g id="coolGroup">
        <circle r="5" fill="white" /> 
    </g> 

app/index.js

    import { fitbit_animate } from 'fitbit-animate';

    let element = document.getElementById('coolGroup');

    let sequence = [
        {
            elem: element,
            prop: "translate",
            subprop: "x",
            from: 50,
            to: 100,
            dur: 1000
        },
        {
            elem: element,
            prop: "translate",
            subprop: "y",
            from: 50,
            to: 100,
            dur: 1000
        },
        {
            elem: element,
            prop: "scale",
            subprop: "x",
            from: 1,
            to: 2,
            dur: 1000
        }
    ];

    fitbit_animate(sequence).then(()=>{
        console.log("Animation complete!")
    })

The above example will move circle from position (50, 50) to (100,100) while increasing its size twice, for the duration of 1 second.
