• 注册一个npm账号

在npm官网注册https://www.npmjs.com/

  • 给代码库起名字

不可有重复包名,包名重复不能提交

  • 创建项目

需要一个package.json文件,这个文件不仅仅是用来标明依赖和npm script脚本,也可以是一个npm包被外界识别的配置文件。
因为配置文件内容比较多,可以选择自己手写,或者npm init

package.json

{
  "name": "xxx",
  "version": "1.0.1",
  "description": "公共功能的js",
  "main": "index.js",//你要发布到npm上的组件
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint"
  },
  "author": "xxx",
  "license": "ISC",
  "dependencies": {
    "core-js": "^3.6.5",
    "vue": "^2.6.11"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "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"
  ]
}

 

  • 发布代码

先登录你的账号

$ npm adduser    Username: your name Password: your password Email: yourmail
npm publish

如果提交成功

封装组件发布到npm上_json

  • 测试是否发布成功
  1. 到官网上查看有没有
  2. 下载下来
    npm install 你发布的包名 --save

     

  • 常见报错

下面是一些常见报错:

  • npm publish failed put 500 unexpected status code 401

    一般是没有登录,重新登录一下 npm login 即可

  • npm ERR! you do not have permission to publish “your module name”. Are you logged in as the correct user?

    包名被占用,改个包名即可。最好在官网查一下是否有包名被占用,之后再重命名

  • you must verify your email before publishing a new package

    邮箱未验证,去官网验证一下邮箱
