最终效果如下

一、先创建vue2项目

1、 可以用vue-cli自己来创建；也可以直接使用我开源常规的vue2后台管理系统模板

以下我以 wocwin-admin-vue2 项目为例

修改目录结构，最终如下

2、修改vue.config.js文件

module.exports = {
// 修改 src 目录 为 examples 目录
  pages: {
    index: {
      entry: 'examples/main.js',
      template: 'public/index.html',
      filename: 'index.html'
    }
  },
    // 强制内联CSS（使用组件时，不需要再引入css）
  css: {
    extract: false
  },
  // 别名
  configureWebpack: config => {
    config.resolve.alias['@'] = resolve('examples')
    config.resolve.alias['components'] = resolve('examples/components')
    config.resolve.alias['~'] = resolve('packages')
    // 生产环境配置
    if (isProduction) {
      config.mode = 'production'
      // 打包文件大小配置
      config.performance = {
        maxEntrypointSize: 10000000,
        maxAssetSize: 30000000
      }
    }
  }
}

二、组件开发

1、首先需要创建一个 packages 目录，用来存放组件

2、需要注意的是，组件必须声明 name，这个 name 就是组件的标签

3、这里以组件 TTable 为例，完整的 packages/table 目录结构如下：

4、每个组件都应该归类于单独的目录下，包含其组件源码目录 src，和 index.js 便于外部引用

import TTable from './src'

TTable.install = function (Vue) {
  Vue.component(TTable.name, TTable)
}
export default TTable

5、packages 目录下存放每个组件单独的开发目录，和一个 index.js 整合所有组件，并对外导出

1、导入组件，组件必须声明 name

import TAntConfigform from './config-form'
import TAntLayoutConditional from './layout-conditional'
import TLayoutPage from './layout-page'
import TLayoutPageItem from './layout-page-item'
import TAntLayoutTable from './layout-table'
import TAntRangePicker from './range-picker'
import TCalendar from './calendar'
import TDatePicker from './date-picker'
import TDialog from './dialog'
import TEditTable from './edit-table'
import TComplexEditTable from './complex-edit-table'
import TForm from './form'
import TIcon from './icon'
import TInput from './input'
import TInputSearch from './input-search'
import TLayout from './layout'
import TPhone from './phone'
import TProtocol from './protocol'
import TQueryCondition from './query-condition'
import TSearch from './search'
import TStepWizard from './step-wizard'
import TSticky from './sticky'
import TTable from './table'
import TTimerBtn from './timer-btn'
import TTreeTable from './tree-table'
import TUploadFile from './upload-file'
import UploadFile from './UploadFile'
import TAntLayoutForm from './layout-form'
import TModuleForm from './module-form'
import TBtnDate from './btn-date'
import TSelect from './select'
import TPaginationSelect from './pagination-select'
import TDetail from './detail'
import { TAntModal, TAntProtocol } from './modal'
import TSelectTable from './select-table'
import TTreeSelect from './tree-select'
import TButton from './button'
import { version } from '../package.json'
// 存储组件列表
const components = [
  TAntConfigform,
  TAntLayoutConditional,
  TLayoutPage,
  TLayoutPageItem,
  TAntLayoutTable,
  TAntRangePicker,
  TCalendar,
  TDialog,
  TDatePicker,
  TForm,
  TIcon,
  TInput,
  TInputSearch,
  TLayout,
  TPhone,
  TProtocol,
  TQueryCondition,
  TSearch,
  TStepWizard,
  TSticky,
  TTable,
  TTimerBtn,
  TTreeTable,
  TUploadFile,
  UploadFile,
  TAntLayoutForm,
  TAntModal,
  TAntProtocol,
  TModuleForm,
  TComplexEditTable,
  TEditTable,
  TBtnDate,
  TSelect,
  TPaginationSelect,
  TDetail,
  TSelectTable,
  TButton,
  TTreeSelect
]

2、定义 install 方法，接收 Vue 作为参数。如果使用 use 注册插件，则所有的组件都将被注册

const install = function (Vue) {
  // 判断是否安装
  if (install.installed) return
  install.installed = true
  // 遍历注册全局组件
  components.map(component => Vue.component(component.name, component))
}

// 判断是否是直接引入文件
if (typeof window !== 'undefined' && window.Vue) {
  install(window.Vue)
}

3、导出的对象必须具有 install，才能被 Vue.use() 方法安装（全局使用）

export default {
  version,
  // 导出的对象必须具有 install，才能被 Vue.use() 方法安装
  install
}

4、按需引入

export {
  TAntConfigform,
  TAntLayoutConditional,
  TLayoutPage,
  TLayoutPageItem,
  TAntLayoutTable,
  TAntRangePicker,
  TCalendar,
  TDialog,
  TDatePicker,
  TForm,
  TIcon,
  TInput,
  TInputSearch,
  TLayout,
  TPhone,
  TProtocol,
  TQueryCondition,
  TSearch,
  TStepWizard,
  TSticky,
  TTable,
  TTimerBtn,
  TTreeTable,
  TUploadFile,
  UploadFile,
  TAntLayoutForm,
  TAntModal,
  TAntProtocol,
  TModuleForm,
  TComplexEditTable,
  TEditTable,
  TBtnDate,
  TSelect,
  TPaginationSelect,
  TDetail,
  TSelectTable,
  TButton,
  TTreeSelect
}

5、packages/index.js完整代码

import TAntConfigform from './config-form'
import TAntLayoutConditional from './layout-conditional'
import TLayoutPage from './layout-page'
import TLayoutPageItem from './layout-page-item'

import TTimerBtn from './timer-btn'
import TTreeTable from './tree-table'
// import TUploadExcel from './upload-excel'
import TUploadFile from './upload-file'
import UploadFile from './UploadFile'
import TAntLayoutForm from './layout-form'
import TModuleForm from './module-form'
import TBtnDate from './btn-date'
import TSelect from './select'

import { TAntModal, TAntProtocol } from './modal'
import TSelectTable from './select-table'
import TTreeSelect from './tree-select'
import TButton from './button'
// import TTheme from './theme'
import { version } from '../package.json'
// 存储组件列表
const components = [
  TAntConfigform,
  TAntLayoutConditional,
  TLayoutPage,
  TLayoutPageItem,
  TAntLayoutTable,
  TAntRangePicker,
  TCalendar,
  TDialog,
  TDatePicker,
  TForm,
  TIcon,
  TInput,
  TInputSearch,
  TLayout,
  TPhone,
  TProtocol,
  TQueryCondition,
  TSearch,
  // TSimpleForm,
  TStepWizard,
  TSticky,
  TTable,
  TTimerBtn,
  TTreeTable,
  // TUploadExcel,
  TUploadFile,
  UploadFile,
  TAntLayoutForm,
  TAntModal,

  TComplexEditTable,
  TEditTable,
  TBtnDate,
  TSelect,
  TPaginationSelect,
  TDetail,
  TSelectTable,
  TButton,
  TTreeSelect
  // TTheme
]

// 定义 install 方法，接收 Vue 作为参数。如果使用 use 注册插件，则所有的组件都将被注册
const install = function (Vue) {
  // 判断是否安装
  if (install.installed) return
  install.installed = true
  // 遍历注册全局组件
  components.map(component => Vue.component(component.name, component))
}

// 判断是否是直接引入文件
if (typeof window !== 'undefined' && window.Vue) {
  install(window.Vue)
}
// 按需引入
export {
  TAntConfigform,
  TAntLayoutConditional,
  TLayoutPage,
  TLayoutPageItem,
  TAntLayoutTable,
  TAntRangePicker,
  TCalendar,
  TDialog,
  TDatePicker,
  TForm,
  TIcon,
  TInput,
  TInputSearch,
  TLayout,
  TPhone,
  TProtocol,
  TQueryCondition,
  TSearch,
  // TSimpleForm,
  TStepWizard,
  TSticky,
  TTable,
  TTimerBtn,
  TTreeTable,
  // TUploadExcel,
  TUploadFile,
  UploadFile,
  TAntLayoutForm,
  TAntModal,
  TAntProtocol,
  TModuleForm,
  TComplexEditTable,
  TEditTable,
  TBtnDate,
  TSelect,
  TPaginationSelect,
  TDetail,
  TSelectTable,
  TButton,
  TTreeSelect
  // TTheme
}
export default {
  version,
  // 导出的对象必须具有 install，才能被 Vue.use() 方法安装
  install
}

三、修改package.json文件

1、package.json 文件里面有很多字段要填写，否则不能正确发布。最重要的是以下几个：

1. name: 包名，该名字是唯一的。可在 npm 官网搜索名字，如果存在则需换个名字。
2. version: 版本号，不能和历史版本号相同。
3. main: 入口文件，默认为 index.js，这里改为 lib/t-ui-plus.umd.cjs。
4. module: 模块入口，这里改为 lib/t-ui.umd.min.js。
5. private:false
6. repository----仓库地址
7. homepage----组件文档或demo示例
8. keywords-----关键字（便于搜索）

2、在package.json 文件scripts里面新增一条lib打包命令：

Vue CLI 中提供了构建库的方法，你可以通过下面的命令将一个单独的入口构建为一个库：

vue-cli-service build --target lib --name myLib [entry]

target: 改为 lib 可启用构建库模式应用模式
name: 构建库输出的文件名；
dest: 构建的输出目录，默认为 dist；
entry: 打包入口文件路径；

"scripts": {
   "lib": "vue-cli-service build --target lib --name t-ui --dest lib packages/index.js",
 }

npm_381">四、发布到npm

npm__registry_382">1、先查看 npm 的 registry

npm config get registry

npm__registry__386">2、设置 npm 的 registry 为官方源

npm config set registry https://registry.npmjs.org

npm_login__npm_390">3、执行命令 npm login 登录到 npm

npm_publish__npm_391">4、执行命令 npm publish 发布到 npm

如出现以下信息，则证明包发布成功:

npm__72__72__394">5、注：上传的 npm 包，在 72小时 后不可删除，如果是测试用的包，记得 72小时 内删除。

五、安装使用

// 先安装
npm i @wocwin/t-ui
// 1、 在main.js中按下引入(全局使用)
import Tui from '@wocwin/t-ui'
Vue.use(Tui)
// 2、按需引入，在单个vue文件如下引入，在注册；或者在main.js中如下引入在注册，皆可！
import { TTable, TLayoutPage, TLayoutPageItem, TForm, TQueryCondition } from '@wocwin/t-ui'
