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 🙏

一个文件预览插件

Usage

安装

npm install @fast-snail/vue-components

ts 配置

如果在全局 app.use 了,则在全局的 *.d.ts (比如 vite-env.d.ts) 中添加

/// <reference types="@fast-snail/vue-components/es/components.d.ts" />

修改全局配置

import VueCom, { InputNumber, globalConfig } from '@fast-snail/vue-components'

// 组件配置在全局引用前修改
Object.assign(InputNumber.props, {
  tip: {
    type: Boolean,
    default: true
  }
})
app.use(VueCom)

// 其他全局配置项修改
Object.assign(globalConfig, {
  //
})

版本要求

package.json

"element-plus": "^2.4.4",
"vue": "^3.4.0"

API

RowCol

对 el-row 和 el-col 的简写,内部同级元素默认按一行 3 列排布

  • gutter: 每列间距 number 默认 20
  • baseSpan: 每列占据 24 等分的几份 number 默认 8

如果想对但列处理,在列上添加 span 属性

<template>
  <RowCol :gutter="20" :baseSpan="8">
    <div>占据8</div>
    <div v-if="false">占据0</div>
    <div :span="24">占据24</div>
  </RowCol>
</template>

useMountActivated

组件显示或激活的回调,主要因为页面初始化 mount 和 activate 会都执行,但只想要其中一个执行

useMountActivated(
  () => {
    // 页面Mount或Activate执行了
  },
  sources,
  fn
)

sources 和 fn 为非必要。为 watch 的前两个参数

useElementRect

获取元素的位置信息,内部调用了 dom.getBoundingClientRect()方法,如果不在 hook 中则直接使用 getBoundingClientRect

const { rect, updateRect } = useElementRect(el, (interval = true))

watch(
  () => rect.value.top,
  val => {
    console.log('距离顶部', val)
  }
)

interval 为轮训参数,如果知道页面什么时候变动可以直接调用 updateRect

useTableSelect

管理 el-table 的多选事件

<template>
  <el-table
    :data="list"
    row-key="id"
    ref="tableRef"
    @select="toggleSelection"
    @select-all="toggleAllSelection"
  >
    <el-table-column type="selection" width="50" align="center" />
  </el-table>
</template>
<script setup lang="ts">
/**
 * 列表多选变化方法
 * tableData: 表格数据
 * selectData: 选中数据
 * rowKey: 行key
 * ref: 表格ref
 * cb: 选中内容的回调
 *
 * 请将返回值
 * toggleAllSelection, toggleSelection
 * 传递给el-table
 */

const list = ref([]) // 列表数据
const selectData = ref([]) // 选中数据
const tableRef = ref(null) // el-table的ref
const { toggleSelection, toggleAllSelection } = useTableSelect({
  tableData: list,
  selectData,
  ref: tableRef,
  cb: resp => {
    selectData.value = resp || []
  }
})
</script>

useBaseTable 和 useDataTable

处理列表分页和静态数据分页

/**
// 简单使用示例
const { pagination, paginationEvent, rows, loading, query, reset } =
  useBaseTable(api, { handlePlayed: (params) => params.other = '123' });

// 分页使用示例
<div style="text-align: right">
  <el-pagination v-bind="pagination" v-on="paginationEvent" />
</div>
 */

InputNumber

数字输入框

  • min?: number | string
  • max?: number | string
  • precision?: number | string // 精度
  • symbol?: string | boolean // 符号 默认为%
  • tip?: boolean // 大写提示

注意输入框的部分配置会在 globalConfig 中调整

import { globalConfig } from '@fast-snail/vue-components'

Object.assign(globalConfig, {
  MAXLENGTH: 100, // 最大位数,默认16
  MAX_SAFE_INTEGER: 'Infinity', // 最大安全值,默认900...
  DECIMAL_ROUNDING: Decimal.ROUND_DOWN // 默认四舍五入
})

简单的数字输入框和万元输入框改造。

  1. 输入框为字符串,但后端可能要求是数字的情况
  2. 展示金额要求为万元的形式
  3. 注意,此时MAXLENGTHMAX_SAFE_INTEGER请不要调大,只能不调或调小。因为会有精度丢失
<!-- WanInputNumber -->
<template>
  <InputNumber v-model="modelValue" :precision="precision" :symbol="symbol" />
</template>

<script setup lang="ts">
import { defineProps, defineEmits, computed } from 'vue'
import Decimal from 'decimal.js'
import { isEmpty } from '@fast-snail/vue-components'

const props = defineProps<{
  modelValue?: number
  symbol?: string
  precision?: number
}>()

// 是万元,默认保留7位小数到毫
const precision = computed(() => {
  if (props.symbol === '万元') {
    return isEmpty(props.precision) ? 7 : props.precision
  }
  return isEmpty(props.precision) ? undefined : props.precision
})

const emit = defineEmits<{
  (e: 'update:modelValue', value?: number): void
  (e: 'change', value?: number): void
  (e: 'input', value?: number): void
}>()
const modelValue = computed({
  get: () => {
    if (props.symbol === '万元') {
      return isEmpty(props.modelValue)
        ? ''
        : new Decimal(props.modelValue).div(10000).toFixed()
    }
    return isEmpty(props.modelValue) ? '' : props.modelValue.toString()
  },
  set: (val?: string) => {
    const change = (e?: number) => {
      emit('update:modelValue', e)
      emit('input', e)
      emit('change', e)
    }

    if (!val) {
      change(undefined)
      return
    }
    if (props.symbol === '万元') {
      change(new Decimal(val).mul(10000).toNumber())
    } else {
      change(Number(val))
    }
  }
})
</script>

使用

<WanInputNumber v-model="wanInputValue" symbol="万元" />

format-money

数字格式化操作 formatMoney(number, fixed = 2),默认保留两位小数

  • 第一位为数字或字符串
  • 第二位为要保留的小数,默认 2 number。如果为负数则有几位就保留几位

转万元formatMoneyWan(number, fixed = 6, div = 10000)

  • div 表示除以多少 number 默认一万
import { globalConfig } from '@fast-snail/vue-components'

// 调整默认配置
Object.assign(globalConfig.formatMoney, {
  fixed: 4
})
Object.assign(globalConfig.formatMoneyWan, {
  fixed: 4,
  div: 10000
})

numToCapital

数字转汉字numToCapital(number, big?: boolean)

  • 第二位为转大写汉字

checkEllipsis

检查 dom 节点文字是否超出隐藏了,返回 true 或 false

numToCapital(document.querySelector('body'))
