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 🙏

add-doom-fire

adicione doom fire ao seu projeto react.js (ou outro framework) ou js puro

JS Puro:

Download do arquivo fire.js e remova a linha module.exports = Fire

Adicione o script no arquivo html:

    <body>
        <canvas width="300" height="300"></canvas>
        <script src="./fire.js"></script>

        <script>
            const canvas = document.querySelector("canvas"); //Tag canvas
            const context = canvas.getContext("2d"); //Contexto 2d do canvas

            const fireWidth = canvas.width; //largura do canvas
            const fireHeight = canvas.height; //altura do canvas
            const proportionalValue = 5; //Tamanaho do quadro que o fogo vai renderizar (padrão 5 ou 10)
            const backgroundIntensity = 0; //Fundo do canvas, cores disponíves: { 0, 1, 2... 36 }

            fire = new Fire(context, fireWidth, fireHeight, proportionalValue, backgroundIntensity);
            fire.Start(); 
        </script>
    </body>

Exemplo com React.js:

Adicione o add-doom-react

    yarn add add-doom-fire

Or

    npm install add-doom-fire

Importe o useRef do react e o add-doom-fire

    import React, { useRef } from 'react';
    import Fire from "add-doom-fire";

Crie um userRef

    const canvasHTMLElement = useRef();
    let fire;

Retorne um HTML com uma tag canvas

Passe o atributo ref na tag canvas e adicione dois botões com uma função de click

    return (
        <div className="App">
            <canvas ref={canvasHTMLElement} width="300" height="300"></canvas>
            <button onClick={createFire}>Start Fire</button>
            <button onClick={stopFire}>Stop Fire</button>
        </div>
  );

Manipule o objeto pra criar o fogo ao clicar no botão

  function createFire() {
    const canvas = canvasHTMLElement.current; //Tag canvas
    const context = canvas.getContext("2d"); //Contexto 2d do canvas

    const fireWidth = canvas.width; //largura do canvas
    const fireHeight = canvas.height; //altura do canvas
    const proportionalValue = 5; //Tamanaho do quadro que o fogo vai renderizar (padrão 5 ou 10)
    const backgroundIntensity = 0; //Fundo do canvas, cores disponíves: { 0, 1, 2... 36 }
    
    fire = new Fire(context, fireWidth, fireHeight, proportionalValue, backgroundIntensity);
    fire.Start(); //Inicia o fogo do DOOM
  }

  function stopFire() {
    fire.Stop() // Para o fogo do doom
  }
