加载某个目录到一个对象上

加载某个目录到一个对象上

如果我想加载某个目录到一个对象上，需要如何做呢？

准备

mkdir require-dictory
cd require-dictory
ls
npm init
npm i -S require-directory
touch index.js

核心代码

var requireDirectory = require('require-directory');
module.exports = requireDirectory(module);

测试

touch test.js

var obj = require('./index')

console.log(obj);

然后

➜  require-dictory git:(master) ✗ node test.js
{ node_modules: { 'require-directory': { index: [Object], package: [Object] } },
  package:
   { name: 'require-dictory',
     version: '1.0.0',
     description: '',
     main: 'index.js',
     scripts: { test: 'echo "Error: no test specified" && exit 1' },
     author: '',
     license: 'ISC',
     dependencies: { 'require-directory': '^2.1.1' } },
  test: {} }

此时index对象就返回了index和test和package.json里的内容

测试,创建third.js

➜  require-dictory git:(master) ✗ touch third.js
➜  require-dictory git:(master) ✗ node test.js
{ node_modules: { 'require-directory': { index: [Object], package: [Object] } },
  package:
   { name: 'require-dictory',
     version: '1.0.0',
     description: '',
     main: 'index.js',
     scripts: { test: 'echo "Error: no test specified" && exit 1' },
     author: '',
     license: 'ISC',
     dependencies: { 'require-directory': '^2.1.1' } },
  test: {},
  third: {} }

此时，这个模块就写完啦，打印出当前模块下的挂载的所有对象

如何发布npm模块

那么我们来发布一个吧，顺便学习一下如何发布npm模块

• 登陆npm
• 发布

➜  require-dictory git:(master) ✗ nrm use npm

   Registry has been set to: https://registry.npmjs.org/

➜  require-dictory git:(master) ✗ npm login
Username: i5ting
Password:
Email: (this IS public) shiren1118@126.com

一定要注意nrm use npm，源一定要是npmjs，不然是无法登陆成功的。

然后在package.json所在目录里

npm publish .

即可

可以在package.json里增加start，每次发布模块的时候能简单点
