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 🙏

Victory Animation

victory-animation is a React wrapper component that uses the D3 interpolate and ease libraries to provide transitions between prop sets.

##Examples

The most basic set up you can use will require supplying a data prop and rendering a functional child, as shown below:

<VictoryAnimation data={x: 500}>
  {(data) => {
    return <div style={{left: data.x}}/>
  }}
</VictoryAnimation>

The way victory-animation works is, when you supply the initial value for the data prop, the functional child gets called and your child/children are rendered with that data. Any subsequent data supplied via the data prop is interpolated against the original or current value, and the child is rerendered along a transition sequence until it reaches its final value, which is the prop that was supplied.

For example, lets check out a simple example using a button to toggle between data prop values:

class App extends React.Component {
  constructor(props) {
    super(props);
    this.clickHandler = this.clickHandler.bind(this);
    this.state = {
      x: 0
    };
  }
  clickHandler() {
    this.setState({
      x: this.state.x === 0 ? 150 : 0
    });
  }
  render() {
    return (
      <div>
        <button type="button" onClick={this.clickHandler}>Toggle X</button>
        <VictoryAnimation data={{x: this.state.x}}>
          {(data) => {
            return (
              <div style={{left: data.x}} />
            );
          }}
        </VictoryAnimation>
      </div>
    );
  }
}

We can expand on this by adding multiple values, as VictoryAnimation supports object interpolation with interpolation of any properties contained using any type supported by d3-interpolate:

class App extends React.Component {
  constructor(props) {
    super(props);
    this.clickHandler = this.clickHandler.bind(this);
    this.state = {
      x: 0,
      w: 500,
      h: 500,
      br: 0,
      color: "#3498db",
      rotate: 0
    };
  }
  clickHandler() {
    this.setState({
      x: this.state.x === 0 ? 150 : 0,
      w: this.state.w === 500 ? 200 : 500,
      h: this.state.h === 500 ? 200 : 500,
      br: this.state.br === 500 ? 0 : 500,
      color: this.state.color === "#3498db" ? "#2ecc71" : "#3498db",
      rotate: this.state.rotate === 0 ? 360 : 0
    });
  }
  render() {
    return (
      <div>
        <button type="button" onClick={this.clickHandler}>Toggle X</button>
        <VictoryAnimation data={
          {
            x: this.state.x,
            w: this.state.w,
            h: this.state.h,
            color: this.state.color,
            br: this.state.br,
            rotate: this.state.rotate
          }}>
          {(data) => {
            return (
              <div style={
                {
                  position: "relative",
                  left: data.x,
                  width: data.w,
                  height: data.h,
                  backgroundColor: data.color,
                  color: "white",
                  fontFamily: "Lucida Grande",
                  padding: 40,
                  borderRadius: data.br,
                  textAlign: "center",
                  alignItems: "center",
                  display: "flex",
                  fontSize: 40,
                  transform: "rotate(" + data.rotate + "deg)"
                }}>
                <div style={{textAlign: "center", width: "100%"}}>Test</div>
              </div>
            );
          }}
        </VictoryAnimation>
      </div>
    );
  }
}

simple example

We can even take this a step further, as VictoryAnimation supports arrays of objects as a type for data. This results in chained ordered animations between multiple sets of properties:

class App extends React.Component {
  constructor(props) {
    super(props);
    this.clickHandler = this.clickHandler.bind(this);
    this.state = {
      data: [
        {
          x: 0,
          y: 0
        }
      ]
    };
  }
  clickHandler() {
    this.setState({
      data: [
        {
          x: 0,
          y: 0
        },
        {
          x: 250,
          y: 0
        },
        {
          x: 250,
          y: 250
        },
        {
          x: 0,
          y: 250
        },
        {
          x: 0,
          y: 0
        }
      ]
    });
  }
  render() {
    return (
      <div>
        <button type="button" onClick={this.clickHandler}>Toggle X</button>
        <VictoryAnimation data={this.state.data}>
          {(data) => {
            return (
              <div style={
                {
                  position: "relative",
                  left: data.x,
                  top: data.y,
                  width: 200,
                  height: 200,
                  backgroundColor: "#2ecc71",
                  borderRadius: 500
                }}>
              </div>
            );
          }}
        </VictoryAnimation>
      </div>
    );
  }
}

The resulting render looks like:
