1、在项目任意位置创建index.ts文件
2、导入要到处的组件，使用vue提供的install 功能全局挂在；

import GWButton from "@/views/GWButton.vue";
import GWAbout from "@/views/AboutView.vue";

const components = {
  GWButton,
  GWAbout,
};

function install(Vue: any) {
  const keys = Object.keys(components);
  keys.forEach((name) => {
    // eslint-disable-next-line @typescript-eslint/ban-ts-comment
    // @ts-ignore
    const component = components[name];
    Vue.component(component.name || name, component);
  });
}

export default {
  install,
  ...components,
};

3、package.json中添加如下命令
完整代码

{
  "name": "gw-components",
  "version": "0.1.0",
  "private": false,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "test:unit": "vue-cli-service test:unit",
    "test:e2e": "vue-cli-service test:e2e",
    "lint": "vue-cli-service lint",
    "package": "vue-cli-service build --target lib --dest lib src/components/index.ts"
  },
  "main": "lib/gw-components.umd.min.js",
  "dependencies": {
    "axios": "^1.6.6",
    "core-js": "^3.8.3",
    "element-plus": "^2.5.3",
    "lodash": "^4.17.21",
    "register-service-worker": "^1.7.2",
    "vue": "^3.2.13",
    "vue-class-component": "^8.0.0-0",
    "vue-router": "^4.0.3",
    "vuex": "^4.0.0"
  },

• 将private设置为false，否则无法发布到npm
• 将name修改为我们的组件库的名字
• version为组件库的版本，每次打包发布注意都要更新
• 增加main为lib/like-ui.umd.min.js，我们组件库打包好的入口文件。 build:like-ui命令中
• –target 允许将项目中的任何组件构建为库或Web组件。
• –dest 打包后的输出文件夹
• 最后就是我们组件库的入口文件src/components/index.js

4、配置完成后，进行打包
打包后会生成如下文件

npm run package

5、上传npm

1、）登陆NPM，输入账号密码

npm login

2）、发布

//这里我上传的私服，上传公网步骤一样；
npm publish --registry http://xx.xx.xx.xx:4873

5、在另一个项目中使用

//使用npm 下载
npm install gw-components@0.1.0

在main.ts 中挂载

import { createApp } from "vue";
import App from "./App.vue";
import "./registerServiceWorker";
import router from "./router";
import store from "./store";
// eslint-disable-next-line @typescript-eslint/ban-ts-comment
// @ts-ignorey
import ElementPlus from "element-plus";
import "element-plus/dist/index.css";
// eslint-disable-next-line @typescript-eslint/ban-ts-comment
// @ts-ignorey
import GWComponents from "gw-components";
import "gw-components/lib/gw-components.css";

createApp(App)
  .use(store)
  .use(router)
  .use(GWComponents)
  .use(ElementPlus)
  .mount("#app");

在组件中直接使用即可

<template>
  <div class="home">
    <GWButton></GWButton>
  </div>
</template>

<script lang="ts">
import { Options, Vue } from "vue-class-component";
import HelloWorld from "@/components/HelloWorld.vue"; // @ is an alias to /src

@Options({
  components: {
    HelloWorld,
  },
})
export default class HomeView extends Vue {}
</script>
