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 🙏

生成水印

前言

其一:在PC端,对内部系统的截图应该考虑安全问题,截图内容不管是否敏感不可泄露,安全问题也不容忽视。

为整个系统页面增加水印,对于内部人员的截图等敏感操作能够起到一定的提示作用。

其二:对于移动端,类似于渣浪微博在发布动态后会为图片添加带有个人标记的水印。

本库基于canvas提供以上两种添加水印的方式。

Usage

npm i @careteen/watermark -D

then

import waterMark from '@careteen/watermark'
waterMark({
  type: 'page',
  content: 'careteen'
})
// or
waterMark({
  type: 'image',
  url: 'http://localhost:3000/imgs/google.png',
  content: 'careteen',
  cb: (base64Url) => {
    document.querySelector('img').src = base64Url
  }
})
