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 🙏

components-extent

v1.1.2-beta.43

Readme

npm version

全局安装

import componentsExtent from 'components-extent';
app.use({option}, componentsExtent);

推荐components-extent引入放在main.js最上方,否则extend.js方法异常

option:

uploadFunction:上传文件的方法,返回格式为 {hash: filePath}

fileHashFunction:验证文件md5方法, 返回格式为 {hash: filePath}

axiosInstance:axios请求工具对象

按需引入

请查看 index.js文件

注意

element-ui 相关的组件需要单独注册

import ElementExtent from 'components-extent/element/index.js';
app.use(ElementExtent);

表格工具

import {ElTableExt} from 'components-extent';
ElTableExt.setApi(Api); // 必须设置API,或者在data中设置api属性
mixins: [ElTableExt]

默认自动获取表格数据(调用api中的page方法),可以设置autoInit: false关闭

<div>
    <div class="table-button">
      <div class="table-button-left" @keydown.enter="getTableList">
        <div class="table-button-item">
          <label>名称</label>
          <el-input v-model="queryParam.name_like" clearable size="small"></el-input>
        </div>
      </div>
      <div class="table-button-right">
        <el-button @click="getTableList" size="small" type="primary">搜索/刷新</el-button>
      </div>
    </div>
    <el-table ref="table" :data="table.list" :max-height="table.height"
      :default-sort="defaultOrder"
      v-loading="table.loading"
      class="h-table"
      border
      @sort-change="defaultSortMethod"
      @select="handerSelect">
      <h-table-column prop="newsTitle" label="标题" sortable="custom"></h-table-column>
      <el-table-column fixed="right" label="操作" width="120">
        <template #default="{row}">
          <el-button type="text" size="small" @click="toEditPage(row)" >编辑</el-button>
          <el-button type="text" class="error-text" size="small" @click="deleteRow(row)">删除</el-button>
        </template>
      </el-table-column>
    </el-table>

    <h-pageination :page="page" align="right" :refresh="getTableList"></h-pageination>
  </div>

from工具

import {ElFormExt} from 'components-extent';
mixins: [ElFormExt]

提供监听表单数据修改功能

contextmenu 右键菜单

let menus = [
  {
    name: '菜单',
    params: 123
    click: function(params, ...args){
    }
  }
]
import {contextmenu} from 'components-extent';
contextmenu.handerContextmenu(event, menus, 'aaa');

FileUtil 文件工具

提供上传和文件路径处理, 需要先设置 uploadFunction 和 fileHashFunction 方法 设置方式一、全局引入时设置 方式二、

import {extentContext} from 'components-extent';
extentContext().uploadFunction = function(){}

方式三、 调用时传入 import {FileUtil} from 'components-extent'; FileUtil.upload(file, {uploadFunction: Function});

file 可以是InputHTMLEleement, File, Blob, Array

emitter 事件处理

import {emitter} from 'components-extent';

emitter.post('xxx', 123);
emitter.on('xxx', Function);

TemplateApi

模板API封装了通用的Api方法

MaxFileUploader

超大文件上传,上传步骤:

  1. 初始化
  2. 计算总任务数
  3. 分片
  4. 请求开启分片上传任务
  5. 依次上传分片
  6. 请求合并分片
  7. 获取结果
  • 用法
import {MaxFileUploader} from 'components-extent';
let uploder = new MaxFileUploader({
  url: 'xxx',
  md5Url: new URL('./md5.js', location),
  params: {},
  axios
});

uploader.progress((params, status, count, total, message) => {
  // 进度
})

uploader.then((params, res) => {
  // 上传完成
})

uploader.finally((params) => {
  // 最终调用
})

uploader.reserve((param)=>{
  // 不满足分片规则时调用
})

// 销毁
uploder.destroy()
  • 构造函数参数:config
{
  // 每个分片大小,单位字节,默认20M
  chunkSize: 20971520,
  // 设置文件最小多大才开始分割,单位字节,默认100M
  thresholdSize: 104857600,
  // 上传时并发数,默认10个
  concurrency: 10,
  // 基础的url,非空,接口必须准守规则
  url: null,
  // 开启分片上传任务请求配置
  startRequest: {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
  },
  // 上传分片文件请求配置
  uploadRequest: {
    method: 'PUT',
  },

  // 获取结果请求配置
  resultRequest: {
    method: 'GET',
  },

  // 开始合并请求配置
  mergeRequest: {
    method: 'GET',
  },

  // MD5的url,用于计算分片的hash值,类型必须是URL
  md5Url: null,

  // 是否自动关闭线城池
  autoCloseThreadPool: true,
  // 线程池,默认自动创建
  threadPool: null
}

retry

重试工具

  • 用法
import {utils} from 'components-extent';

utils.retry(function(){
  // 业务代码
}, {maxCount: 100});
  • 方法参数
retry(fn, options)
fn {Funtion} 执行方法
options {Object} 配置
  maxCount: Number, // 最大重试次数,默认3次
  exceptionOut: 出现异常退出,默认false
  interval: 间隔多久一次

ThreadPool

js线城池

  • 参数

    • 构造参数config

      // 线城池大小默认4个
      coreSize: 4
    • init和submit

      submit(fn, ...args)
      fn {Function} 执行的方法,如果调用submit,方法中必须调用postMessage方法,参数为对象success和args
      args {...Any} 方法需要的参数
  • 用法

import {ThreadPool} from 'components-extent';
let threadPool = new ThreadPool(config)
// 初始化
threadPool.init((args1, args2)=>{
  // 初始化代码
}, args1, args2)

// 提交任务
threadPool.submit((args1, args2)=>{
  // 执行代码
  // 执行完成需要调用
  postMessage({
    success: true,
    args: {}
  })
}, args1, args2).then(res => {
  // 执行成功后
})

// 销毁
threadPool.destroy()
