构建npm包

1. 新建文件夹，进入文件夹，执行命令

npm init

2. 完善项

{
  "name": "xvpackage", //包名
  "version": "0.0.1", //版本号
  "description": "", //描述
  "main": "index.js", //入口js
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",  //作者
  "license": "MIT"  //协议
}

3. 目录结构

• xvpackage
  • lib
    • index.js
  • test
    • test.js
  • node_modules
  • package.json
  • README.md
  • History.md

4. 新建lib/chineseOrderBy.js文件

'use strict';
//标记es6写法
Object.defineProperty(exports, "__esModule", {
  value: true
});
exports.default = tableOnSort;

    /**
   * 表格排序
   * @param {*数字字段名数组} numArr
   * @param {*数据集合} tableDataList
   * @param {* 字段名} dataIndex
   * @param {* 排序名} order
   */
function tableOnSort(numArr=[],tableDataList,dataIndex,order){
    let dataSource = tableDataList.sort(function(a, b) {

      if(numArr.includes(dataIndex)){
        let result = a[dataIndex] - b[dataIndex];
        return order === "asc" ? (result > 0 ? 1 : -1) : result > 0 ? -1 : 1;
      }

      return order === "asc" ? String(a[dataIndex]).localeCompare(String(b[dataIndex])) : String(b[dataIndex]).localeCompare(String(a[dataIndex]));
    });
    return dataSource;
  }
  module.exports = exports['default'];

5. 完善lib/index.js文件

'use strict';

Object.defineProperty(exports, "__esModule", {
  value: true
});

var _ChineseOrderBy1 = require('./chineseOrderBy.js');
var _ChineseOrderBy2 = _interopRequireDefault(_ChineseOrderBy1);



function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; }

exports.default =_ChineseOrderBy2.default;
module.exports = exports['default'];

6. test/test.js

7. 初次发布

• npm官网创建账号
• 执行 npm adduser 发布（输入用户名，账号，邮箱）
• 激活邮件
• npm public

8. 再次发布

• 修改代码
• 修改package.json中的version
• npm publish
