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 🙏

✨ 特性

  • 🔄 一键转换 - Processing 代码 → Vue 3 组件
  • 实时预览 - 边写边看效果
  • 🎯 p5.js 驱动 - 基于成熟的 p5.js 库
  • 📦 零配置 - 开箱即用,无需复杂设置
  • 🎨 完整支持 - 图形、颜色、坐标变换、动画等
  • 📦 npm 包 - 方便集成到你的项目

🚀 快速开始

方式一:命令行使用

# 安装
npm install -g processing2vue

# 转换单个文件
p2v input.pde output.vue

# 或直接转换(自动命名)
p2v input.pde

方式二:在 Vue 项目中使用

# 安装
npm install p5 processing2vue
<template>
  <MyProcessingSketch />
</template>

<script setup>
import MyProcessingSketch from './MyProcessingSketch.vue'
</script>

方式三:编程方式

import { convert } from 'processing2vue'

const processingCode = `
void setup() {
  size(400, 400);
}

void draw() {
  background(0);
  circle(mouseX, mouseY, 50);
}
`

const vueComponent = convert(processingCode)
console.log(vueComponent)

📖 使用示例

输入 Processing 代码

void setup() {
  size(400, 400);
  background(0);
}

void draw() {
  // 跟随鼠标的渐变圆
  background(0, 20);

  for (int i = 5; i > 0; i--) {
    fill(0, 200, 255, 50);
    circle(mouseX, mouseY, i * 30);
  }
}

输出 Vue 3 组件

<template>
  <div class="processing-wrapper">
    <div ref="canvasContainer"></div>
  </div>
</template>

<script setup>
import { ref, onMounted, onUnmounted } from 'vue'
import p5 from 'p5'

const canvasContainer = ref(null)
let sketchInstance = null

const sketch = (p) => {
  p.setup = () => {
    p.createCanvas(400, 400)
    p.background(0)
  }

  p.draw = () => {
    p.background(0, 20)

    for (let i = 5; i > 0; i--) {
      p.fill(0, 200, 255, 50)
      p.circle(p.mouseX, p.mouseY, i * 30)
    }
  }
}

onMounted(() => {
  if (canvasContainer.value) {
    sketchInstance = new p5(sketch, canvasContainer.value)
  }
})

onUnmounted(() => {
  if (sketchInstance) {
    sketchInstance.remove()
    sketchInstance = null
  }
})
</script>

<style scoped>
.processing-wrapper {
  width: 400px;
  height: 400px;
}
.processing-wrapper canvas {
  display: block;
}
</style>
