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 🙏

加强版 img 标签,仿微信小程序 image 标签,多种裁剪、缩放模式,异步加载图片,支持重新加载图片

例子

例:

import Img from '@dyb881/img';
import '@dyb881/img/lib/style.css';

// 直接使用
<Img src="" />
// 不显示图片,只显示占位div
<Img src="" show={false} />
// 提示内容或按钮自定义
<Img src="" loadedTip="加载中" reloadTip="重新加载" />
// 可以完整地将图片显示出来
<Img src="" mode="aspectFit" style={{width: 100, height: 100}} />
// 可以完整地将图片显示出来, 并靠左上角
<Img src="" mode={['aspectFit', 'left', 'top']} style={{width: 100, height: 100}} />
// 不缩放图片, 只显示图片的左上边区域
<Img src="" mode={['left', 'top']} style={{width: 100, height: 100}} />

输入参数

interface IProps {
  src?: string; // 图片地址
  mode?: 'none' | mode | mode[]; // 裁剪、缩放模式 default none
  show?: boolean; // 显示图片 default true
  loadedTip?: React.ReactNode; // 加载提示内容 default 加载中
  reloadTip?: React.ReactNode; // 刷新提示内容 default 重新加载
  [key: string]: any;
}

mode

注!只有在 className 或 style 设置了高宽才能生效

mode 的值可以为数组,任意组合以下模式

scaleToFill 缩放模式,不保持纵横比缩放图片,使图片的宽高完全拉伸至填满 image 元素 aspectFit 缩放模式,保持纵横比缩放图片,使图片的长边能完全显示出来。也就是说,可以完整地将图片显示出来。 aspectFill 缩放模式,保持纵横比缩放图片,只保证图片的短边能完全显示出来。也就是说,图片通常只在水平或垂直方向是完整的,另一个方向将会发生截取。 top 裁剪模式,不缩放图片,只显示图片的顶部区域 bottom 裁剪模式,不缩放图片,只显示图片的底部区域 center 裁剪模式,不缩放图片,只显示图片的中间区域 left 裁剪模式,不缩放图片,只显示图片的左边区域 right 裁剪模式,不缩放图片,只显示图片的右边区域
