# 发布一个自己的NPM包 #

用了这么多次别人发布的包，今天咱们自己发布一个npm包

## 首先检查npm源 ##

npm get registry
    # 如果不是这个地址https://registry.npmjs.org 需要设置官网源
    npm config set registry https://registry.npmjs.org
    复制代码

如果是使用第三方源请设置npm官方源 `(注)：第三方源只提供下载功能`

## 创建模块 ##

npm init 
    
    # package.json 内容
    {
      "name": "isnumber-lpz",
      "version": "1.0.0",
      "description": "Number\u001b[D\u001b[D\u001b[D\u001b[D\u001b[D\u001b[D\u001b[D\u001b[D\u001b[D\u001b[C\u001b[C\u001b[Cis\u001b[C\u001b[C\u001b[Number",
      "main": "index.js",
      "scripts": {
        "test": "echo \"Error: no test specified\" && exit 1"
      },
      "repository": {
        "type": "git",
        "url": "git+https://github.com/lanpangzhi/isNumber-lpz.git"
      },
      "author": "lanpangzhi",
      "license": "ISC",
      "bugs": {
        "url": "https://github.com/lanpangzhi/isNumber-lpz/issues"
      },
      "homepage": "https://github.com/lanpangzhi/isNumber-lpz#readme"
    }
    
    # 创建 index.js
    touch index.js
    
    function isNumber(number) {
      number = parseFloat(number)
      return number === number && typeof number === 'number' 
    }
    
    module.exports = isNumber
    复制代码

[npm使用介绍][npm]里面有里面的字段，这里就省略了，`(注)：包的name不要重名建议先去[https://www.npmjs.com/](https://www.npmjs.com/)搜索下`

## 注册npm账号（有账号跳过这步） ##

npm adduser用于在npmjs.com注册一个用户。

npm adduser
    # Username: 用户名
    # Password: 密码
    # Email: 邮箱
    
    # 登录
    npm login
    复制代码

## 发布包 ##

npm publish
    复制代码

`(注)：发布的时候版本号要和上次的不一样，默认的发布标签是latest、前模块是一个beta版，比如2.1.1-beta，那么发布的时候需要使用tag参数`

## 安装并使用 ##

npm i isnumber-lpz
    
    const isNumber = require('isnumber-lpz')
    
    console.log('12', isNumber(12))   true
    console.log('12.2', isNumber(12.2))    true
    console.log('x12.2', isNumber('x12.2'))   false
    console.log('xacsa', isNumber('xacsa'))   false
    复制代码
