发布vue 的npm包

1、本地启动一个vue项目

2、在src文件下新建index.js

import xxx from './components/xxx.vue'

export default xxx;

3、在src文件夹同级新建index.js

//xxx 代表你的模块

import xxx from './dist/xxx.umd.js';

export default xxx;

3、修改package.json

注意几点

1、build命令设置打包后的vue组件名称

2、设置main为你的index.js (暴露打包后的模块）

3、files设置npm包的白名单，即npm包中的文件，其他的一些文件不会进入npm包中，尽量减小包的体积

// xxx 代表你的模块
{
  "name": "xxx",
  "version": "0.0.2",
  "main": "index.js",
  "files": [
    "dist",
    "index.js"
  ],
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build --target lib --inline-vue --name xxx src/index.js",
    "lint": "vue-cli-service lint"
  },
  "dependencies": {
    "core-js": "^3.6.5",
    "vue": "^2.6.11"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.12",
    "@vue/cli-plugin-eslint": "~4.5.12",
    "@vue/cli-service": "~4.5.12",
    "babel-eslint": "^10.1.0",
    "eslint": "^6.7.2",
    "eslint-plugin-vue": "^6.2.2",
    "vue-template-compiler": "^2.6.11"
  },
  "eslintConfig": {
    "root": true,
    "env": {
      "node": true
    },
    "extends": [
      "plugin:vue/essential",
      "eslint:recommended"
    ],
    "parserOptions": {
      "parser": "babel-eslint"
    },
    "rules": {}
  },
  "browserslist": [
    "> 1%",
    "last 2 versions",
    "not dead"
  ]
}

4、使用npm publish 命令发布到npm源上
