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 🙏

[ 更新日志 ]

一、安装使用

1. 安装

# npm 安装
npm install vue-cropper
# yarn 安装
yarn add vue-cropper

如果你没有使用 npm

在线例子vue-cropper + vue.2x

在线例子vue-cropper@next + vue.3x

服务器渲染 nuxt 解决方案 设置为 ssr: false

module.exports = {
  ...
  build: {
    vendor: [
      'vue-cropper
    ...
    plugins: [
      { src: '~/plugins/vue-cropper', ssr: false }
    ]
  }
}

2. 引入 Vue Cropper

Vue 3 组件内引入

npm install vue-cropper@next
import 'vue-cropper/dist/index.css'
import { VueCropper }  from "vue-cropper";

Vue3 全局引入

import VueCropper from 'vue-cropper'; 
import 'vue-cropper/dist/index.css'

const app = createApp(App)
app.use(VueCropper)
app.mount('#app')

Vue3 CDN 方式引入

<style type="text/css" src="https://cdn.jsdelivr.net/npm/[email protected]/dist/index.css"></style> 
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/vue.global.js"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/vue-cropper.umd.js"></script>
const app = Vue.createApp({...});
app.component('vue-cropper', window['vue-cropper'].VueCropper);

Vue2 组件内引入

import { VueCropper }  from 'vue-cropper' 
components: {
  VueCropper
}

Vue2 全局引入

import VueCropper from 'vue-cropper'
Vue.use(VueCropper)

Vue2 CDN 方式引入

<script src="//cdn.jsdelivr.net/npm/[email protected]/dist/index.js"></script>
Vue.use(window['vue-cropper'].default)

nuxt 引入方式

if(process.browser) {
  vueCropper = require('vue-cropper')
  Vue.use(vueCropper.default)
}

3. 代码中使用

重要! 需要关掉本地的 mock 服务, 不然图片转化会报错 重要! 需要使用外层容器包裹并设置宽高

<vueCropper
  ref="cropper"
  :img="option.img"
  :outputSize="option.size"
  :outputType="option.outputType"
></vueCropper>

二、文档

1. props

目前还不知道什么原因项目里面开启 mock 会导致 file 报错,建议使用时关掉 mock

2. 可用回调方法

  • @realTime 实时预览事件
  • @imgMoving 图片移动回调函数
  • @cropMoving 截图框移动回调函数
  • @imgLoad 图片加载的回调, 返回结果 success, error

@realTime 实时预览事件

    height: previews.h + "px",
    overflow: "hidden",
    margin: "0",
    zoom: 100 / preview.w

    height: previews.h + "px",
    overflow: "hidden",
    margin: "0",

  this.previews = data
}
<div class="show-preview" :style="{'width': previews.w + 'px', 'height': previews.h + 'px',  'overflow': 'hidden',
    'margin': '5px'}">
