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 🙏

React Event Components

Join the chat at https://gitter.im/pagarme/react-event-components

A set of components designed as an idiomatic way of working with global, raw input (keyboard, mouse, touch, etc) in React.

Example

A live demo can be found at https://pagarme.github.io/react-event-components

Install

yarn add react-event-components

or

npm install react-event-components --save

Usage

Key Events

Call the handler everytime a key event happen.

import { KeyDown } from './react-event-components'
import React, { Component } from 'react'

export default class KeyDownExample extends Component {
  constructor() {
    super()
    this.state = {
      x: 0,
      y: 0,
      totalTime: 0,
      color: 'rgb(0,0,0)',
      lastKeyPressed: 'None'
      }
  }

  move(position) {
    this.setState(position)
  }

  render() {
    const {x, y, color} = this.state
    return (
      <div>
        <p>Total time: {Math.floor(this.state.totalTime * 100)/100}</p>
        <p>Last key pressed: {this.state.lastKeyPressed}</p>

        <h1 style={{
          transform: `translate(${x}px, ${y}px)`,
          color: color
        }}>
          Try WASD or QEZC
        </h1>

        <KeyDown when="*" do={(key) => this.setState({ lastKeyPressed: key })} />
        <KeyDown when="w" do={() => this.move({ y: y - 10 })} />
        <KeyDown when="a" do={() => this.move({ x: x - 10 })} />
        <KeyDown when="s" do={() => this.move({ y: y + 10 })} />
        <KeyDown when="d" do={() => this.move({ x: x + 10 })} />
        <KeyDown when="q" do={() => this.move({ x: x - 10, y: y - 10})} />
        <KeyDown when="e" do={() => this.move({ x: x + 10, y: y - 10})} />
        <KeyDown when="z" do={() => this.move({ x: x - 10, y: y + 10})} />
        <KeyDown when="c" do={() => this.move({ x: x + 10, y: y + 10})} />
      </div>
    )
  }
}

Timer Events

Runs a function recurrently. Passes the delta time to handler.

import React, { Component } from 'react'
import { Every } from './react-event-components'

export default class EveryExample extends Component {
  constructor() {
    super()
    this.state = {
      totalTime: 0,
      color: 'rgb(0,0,0)'
    }
  }

  handleTotalTime(dt) {
    const totalTime = this.state.totalTime + dt
    this.setState({
      totalTime: totalTime,
      displayTime: Math.floor(totalTime * 100)/100
    })
  }

  handleColor() {
    const randomHex = () => Math.round(Math.random() * 255)
    this.setState({
      color: `rgb(${randomHex()},${randomHex()},${randomHex()})`
    })
  }

  render() {
    return (
      <div>
        <p style={{ color: this.state.color }}>Total time: { this.state.displayTime }</p>

        <Every frame do={(dt) => this.handleTotalTime(dt)} />
        <Every s="1" ms="500" do={() => this.handleColor()} />
      </div>
    )
  }
}

DeviceOrientation

Call do property every time device orientation changes

import React, {Component} from 'react'
import {DeviceOrientation} from './react-event-components'

export default class DeviceOrientationExample extends Component {
  constructor() {
    super()
    this.state = {
      deviceOrientation: {}
    }
  }

  handleDeviceOrientation = ({beta, gamma, alpha, absolute}) => {
    this.setState({
      deviceOrientation: {
        beta,
        gamma,
        alpha,
        absolute
      }
    })
  }

  render() {
    return (
      <div>
        <DeviceOrientation do={this.handleDeviceOrientation} />

        <h2>DeviceOrientation</h2>

        <p>
          beta: {this.state.deviceOrientation.beta}
          <br />
          gamma: {this.state.deviceOrientation.gamma}
          <br />
          alpha: {this.state.deviceOrientation.alpha}
          <br />
          absolute: {this.state.deviceOrientation.absolute}
        </p>
      </div>
    )
  }
}

WindowResize

Triggered when the user resizes the window, it can be called when the user changes the orientation from portrait to landscape.

import React, { Component } from 'react'
import { WindowResize } from './react-event-components'

export default class WindowResizeExample extends Component {
  constructor() {
    super()
    this.state = {
      title: 'Resize Your Window',
      innerWidth: window.innerWidth
    }
  }

  handleWindowResize(window) {
    this.setState(Object.assign({}, this.state, {
      innerWidth: window.innerWidth
    }))
  }

  render() {
    return (
      <div>
        <WindowResize do={this.handleWindowResize.bind(this)} />

        <p>{this.state.title} {this.state.innerWidth}px</p>
      </div>
    )
  }
}

Battery Status

It will give you the battery status of the user API, if it is available

import { BatteryStatus } from './react-event-components'
import React, { Component } from 'react'

export default class BatteryStatusExample extends Component {
  constructor() {
    super()
    this.state = { }
  }

  render() {
    const {
      charging,
      chargingTime,
      dischargingTime,
      level
    } = this.state

    return (
      <section>
        <BatteryStatus do={this.handleBatteryChange.bind(this)} />

        <h2>BatteryStatus</h2>
        <div>charging: {charging}</div>
        <div>chargingTime: {chargingTime}</div>
        <div>level: {level}%</div>
      </section>
    )
  }

  handleBatteryChange (battery) {
    this.setState({ ...battery })
  }
}
