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 🙏

ImageCropper 图片裁剪

image-cropper是一个基于vue3 typescript开发的图片裁剪组件,展示区域,裁剪大小可自由控制。

安装

# via npm
npm i image-cropper-next

# via yarn
yarn add image-cropper-next

# via pnpm
pnpm add image-cropper-next

# via Bun
bun add image-cropper-next

使用,全局导入(main.ts/main.js)

import { createApp } from 'vue'
import ImageCropper from 'image-cropper-next'
const app = createApp(App)
app.use(ImageCropper)

使用,用的地方导入

默认方式,弹窗模式,不穿入任何参数

点击按钮后会打开弹窗,需要在内部选择图片,然后进行裁剪

<template>
  <image-cropper @confirm="confirm"></image-cropper>
  <img style="width: 200px;" :src="imgUrl" :alt="imgUrl">
</template>
<script setup>
import { ImageCropper } from 'image-cropper-next'
const imgUrl = ref('')
const imageCropperRef = ref()
const confirm = (data) => {
  imgUrl.value = data.dataURL
}
</script>

远端图片裁剪,弹窗模式,不穿入任何参数

自定义配置,通过ref触发open方法,需要传入图片地址,不传入则需要在内部选择图片进行裁剪 远端图片需要配置cross-origin为true,cross-origin-header为"anonymous"

<template>
  <button @click="imageCropperRef.open(image)">打开裁剪框</button>
  <image-cropper ref="imageCropperRef" :cross-origin="true" cross-origin-header="anonymous" @confirm="confirm">
    <template #open></template>
  </image-cropper>
  <img style="width: 200px;" :src="imgUrl" :alt="imgUrl">
</template>
<script setup>
import { ImageCropper } from 'image-cropper-next'
const imgUrl = ref('')

const image = new Image()
image.name = 'test'
image.src = 'https://node.wisdoms.xin/static/img/20230627/zb0XVS9bimage.png'

const imageCropperRef = ref()
const confirm = (data) => {
  imgUrl.value = data.dataURL
}
</script>

直接在页面中显示模式

可通过onPrintImg方法实时获取裁剪后的图片信息

<template>
  <image-cropper :isModal="false" @confirm="confirm" @onPrintImg="onPrintImg">
    <template #open></template>
  </image-cropper>
  <img style="width: 200px;" :src="imgUrl" :alt="imgUrl">
</template>

<script lang="ts" setup>
import { ImageCropper } from 'image-cropper-next'
import { ref } from 'vue';

const imgUrl = ref('')
const confirm = (data: any) => {
  console.log(data);
  imgUrl.value = data.dataURL
}
const onPrintImg = (data: any) => {
  console.log(data);
  imgUrl.value = data.dataURL
}
</script>
