index.js

// 路径  是否查找子目录  找.vue的文件
const requireComponent = require.context('./', true, /\.vue$/);
const install = (Vue) => {
    window.console.log(1212, requireComponent.keys())
    //判断是否注册过 若注册过返回
    if (install.installed) return
    //注册
    install.installed;
    requireComponent.keys().map(component => {
        //获取组件
        const config = requireComponent(component);
        const componentName = config.default.name;
        //注册组件
        Vue.component(componentName, config.default || component);
    })
}
export default install

main.js

import Vue from 'vue'
import App from './App.vue'

import plugins from './plugins/index.js'

Vue.config.productionTip = false

Vue.use(plugins)

new Vue({
  render: h => h(App),
}).$mount('#app')

package.json
注意：name属性不能和已存在的插件重复，每次修改后需要修改version的版本号才能再次发布。

关于README.md 文件，介绍如何使用插件，会体现在插件上传后的网页中，提示用户如何使用该插件。

3. 设置源

//设置源
npm config set registry https://registry.npmjs.org
cnpm config set registry http://registry.npm.taobao.org
//查看源
npm config get registry
cnpm config get registry

发布包时用npm，平时用cnpm

4. 发布包

第一次和非第一次发布包有区分

//第一次发布包，注册用户
npm adduser
//非第一次发布包，登录
npm login

npm publish --access public

5. 撤销包

1. 发布包72小时之内可以撤销

//npm unpublish 插件名称
npm unpublish @bairong-im/bairong-im-demo1@1.0.0 // 删除某个版本
npm unpublish @bairong-im/bairong-im-demo1 --force // 删除整个包

2. 发布包72小时之后，用户可以搜索到包，但是不能下载，在下载时提示用户信息

npm deprecate br-im-demo1 'I no longer maintain this package' --force

6. npm 可以建立Originations

想要上传插件到组织上，需要

1. npm scope初始化目录

npm init --scope=组织名

2. 转移源文件，在package.json 配置name值

"name": "@组织名/插件名",
"description": "插件描述",
