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 🙏

为啥造轮子

背景:由于业务需要,需要在客户端把用户选择的pdf 转成png

  1. 社区发现没有好用的pdf转图片的小而巧库,好不容易找到一个两年前的https://www.npmjs.com/package/convert-pdf-png 完全也跑不同,并且pdf每一页生成一个图片
  2. 在线转的服务:https://app.xunjiepdf.com/pdf2longjpg/ 限制2m文件,并且带水印,去掉这些限制就要买vip

基于1,2,决定封装一个统一的库

功能

在浏览器运行时把pdf文件转成img文件的js

  • 支持转化成长图
  • 无水印
  • 支持转化成png、jpg、jpeg文件

使用

import Pdf2Img from 'mm-pdf-img';
const pdf2Img = new Pdf2Img();

document.querySelector("#upload_pdf").onchange = function (e) {
  // pdf file
  const sourceFile = e.target.files[0];

  pdf2Img.parse(sourceFile).then((file,{
    resolution: 2, //清晰度
  }) => {
   // png file
    console.log(file);
  });
};
