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 🙏

bee-crop

传统的图片裁剪是每裁剪一次,就需要存储对应的图片资源,当裁剪比较频繁时会造成大量的资源浪费。解决此问题,可以仅存储裁剪坐标数据,如此一来,无论源图片被裁剪多少次,图片资源永远唯一,避免了资源的浪费。

一种方法是在服务器端实现,坐标信息拼接进图片的url里面,后端服务返回所需的图片。

另一种方法是在客户端(web)实现,利用canvas生成裁剪图片

引入

  • npm
npm install bee-crop
# or
cnpm install bee-crop
# or
yarn add bee-crop
import 'bee-crop'
