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 🙏

html2pdf-2img

HTML下载成pdf或者img格式,pdf也是以图片形式生成的,并支持水印,pdf支持配置分页元素自动分页,不会截断元素。

基于jspdf.js和watermark.js二次封装,并且优化了pdf的分割判断方式,不会出现截断元素的问题。 使用方法:

  安装:npm i html2pdf-2img

  import JsPdfImg from 'html2pdf-2img'

  new JsPdfImg("#printPage", "导出的图片名称", {
    watermarkOption: {
      watermark_txt: "水印配置",
      z_index: 97,
      watermark_x: 0,
      watermark_y: 0,
      watermark_x_space: 160,
      watermark_y_space: 160,
      watermark_width: 180,
    },
  }).outImage(() => {
    console.log('结束')
  });
  
  new JsPdfImg("#printPage", "导出的pdf名称", {
    pageBreak: ['.title', '#area', 'li', 'h3'], // 当导出pdf时候,这个参数必填
    pageStartOffset: 20, // 每个页头的留空距离
    watermarkOption: {
      watermark_txt: "水印配置",
      z_index: 97,
      watermark_x: 0,
      watermark_y: 0,
      watermark_x_space: 160,
      watermark_y_space: 160,
      watermark_width: 180,
    },
  }).outPdf(() => {
    console.log('结束')
  });

 水印的配置参数:
 watermarkOption: {
    watermark_id: 'wm_div_id',          //水印总体的id
    watermark_prefix: 'mask_div_id',    //小水印的id前缀
    watermark_txt:"测试水印",             //水印的内容
    watermark_x:20,                     //水印起始位置x轴坐标
    watermark_y:20,                     //水印起始位置Y轴坐标
    watermark_rows:0,                   //水印行数
    watermark_cols:0,                   //水印列数
    watermark_x_space:20,              //水印x轴间隔
    watermark_y_space:20,               //水印y轴间隔
    watermark_font:'微软雅黑',           //水印字体
    watermark_color:'black',            //水印字体颜色
    watermark_fontsize:'18px',          //水印字体大小
    watermark_alpha:0.15,               //水印透明度,要求设置在大于等于0.005
    watermark_width:100,                //水印宽度
    watermark_height:100,               //水印长度
    watermark_angle:15,                 //水印倾斜度数
    watermark_parent_width:0,      //水印的总体宽度(默认值:body的scrollWidth和clientWidth的较大值)
    watermark_parent_height:0,     //水印的总体高度(默认值:body的scrollHeight和clientHeight的较大值)
    watermark_parent_node:null,     //水印插件挂载的父元素element,不输入则默认挂在body上
    monitor:true,                   //monitor 是否监控, true: 不可删除水印; false: 可删水印。
    z_index: 9999999,
    watermark_img: '',
 }
