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 🙏

DXF 解析、修改、生成工具包

Readme

dxf-kit

🚀 现代 JavaScript DXF 解析 & 写入工具库
支持浏览器 & Node.js


✨ 特性

  • ✅ 支持 20+ DXF 实体(LINE / CIRCLE / ARC / SPLINE 等)
  • ✅ 解析 DXF → JSON
  • ✅ JSON → DXF 写回
  • ✅ 按图层分组
  • ✅ 浏览器直接下载

📦 安装

npm install dxf-kit

🚀 快速开始
解析 DXF
parseDxf
const data = await parseDxf(dxfString)
console.log(data.entities)
数据结构
  {
    blocks: 字符串,无需在意
    classes: 字符串,无需在意
    entities: 一维数组对象[{}]存储了所有图形对象,
    grouped: parseDxf函数已经数据处理后,可直接在前端方便使用的json数据
    header: 字符串,无需在意
    headerVars:存储了dxf头部所有信息
    layerDefs: 存储了图层信息
    objects: 字符串,无需在意
    tables: 字符串,无需在意 
  }



写回 DXF
------ data必须是整个由parseDxf解析出来的数据 ,
------ 所以你在修改dxf的json数据,从某种意义上来讲,删除新增修改图形操作是在 entities层的数据上进行操作
------ 所以前端在使用 grouped 渲染dxf,操作dxf,需要删除 grouped 内的数据才会有ui效果,同时删除 entities 内对应的那条删除才会在dxf文件内存在删除效果
writeDxf
const dxf = writeDxf(data) 

// 下载dxf文件
downloadDxfFile
downloadDxfFile(dxf, fileName.value || '文件名.dxf')

本地运行:
\```bash
cd demo
npm install
npm run dev
\```
