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 🙏

CardReader 组件

Readme

CardReader 读卡组件

一个基于Element Plus的读卡组件,包含输入框和读卡按钮,点击读卡按钮会触发读卡事件,具体的读卡逻辑需要用户自行实现。

基础示例

<template>
  <CardReader v-model="cardValue" @read-success="handleReadSuccess" @read-error="handleReadError" />
</template>

<script setup>
import { ref } from 'vue'

const cardValue = ref('')

function handleReadSuccess(data) {
  console.log('读卡成功:', data)
}

function handleReadError(error) {
  console.error('读卡失败:', error)
}
</script>

Props

| 属性名 | 说明 | 类型 | 默认值 | | ----------- | -------------- | ------- | -------------- | | modelValue | 输入框的值(v-model) | string | '' | | buttonText | 读卡按钮文字 | string | '读卡' | | placeholder | 输入框占位符 | string | '请输入或读卡' | | disabled | 是否禁用 | boolean | false |

Events

| 事件名 | 说明 | 回调参数 | | --------------- | -------------- | ----------------------- | | update:modelValue | 输入框值变化时触发 | (value: string) => void | | readSuccess | 读卡成功时触发 | (data: any) => void | | readError | 读卡失败时触发 | (error: any) => void |

使用说明

基础使用

最简单的使用方式,只需要绑定v-model:

<template>
  <CardReader v-model="cardValue" />
</template>

<script setup>
import { ref } from 'vue'

const cardValue = ref('')
</script>

自定义按钮文字和占位符

<template>
  <CardReader
    v-model="cardValue"
    button-text="读取卡片"
    placeholder="请点击按钮读卡"
  />
</template>

实现读卡逻辑

组件提供了readSuccessreadError事件,你需要在组件外部实现具体的读卡逻辑,并通过事件监听来处理读卡结果:

<template>
  <CardReader
    v-model="cardValue"
    @read-success="handleReadSuccess"
    @read-error="handleReadError"
  />
</template>

<script setup>
import { ref } from 'vue'

const cardValue = ref('')

function handleReadSuccess(data) {
  console.log('读卡成功:', data)
  // 处理读卡成功逻辑
}

function handleReadError(error) {
  console.error('读卡失败:', error)
  // 处理读卡失败逻辑
}
</script>
