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

  1. mkdir require-dictory
  2. cd require-dictory
  3. ls
  4. npm init
  5. npm i -S require-directory
  6. touch index.js

核心代码

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

测试

touch test.js

  1. var obj = require('./index')
  3. console.log(obj);

然后

  1. ➜  require-dictory git:(master) ✗ node test.js 
  2. { node_modules: { 'require-directory': { index: [Object], package: [Object] } },
  3.   package: 
  4.    { name: 'require-dictory',
  5.      version: '1.0.0',
  6.      description: '',
  7.      main: 'index.js',
  8.      scripts: { test: 'echo "Error: no test specified" && exit 1' },
  9.      author: '',
  10.      license: 'ISC',
  11.      dependencies: { 'require-directory': '^2.1.1' } },
  12.   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

  1. ➜  require-dictory git:(master) ✗ touch third.js
  2. ➜  require-dictory git:(master) ✗ node test.js
  3. { node_modules: { 'require-directory': { index: [Object], package: [Object] } },
  4.   package: 
  5.    { name: 'require-dictory',
  6.      version: '1.0.0',
  7.      description: '',
  8.      main: 'index.js',
  9.      scripts: { test: 'echo "Error: no test specified" && exit 1' },
  10.      author: '',
  11.      license: 'ISC',
  12.      dependencies: { 'require-directory': '^2.1.1' } },
  13.   test: {},
  14.   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
  1. ➜  require-dictory git:(master) ✗ nrm use npm
  3.    Registry has been set to: https://registry.npmjs.org/
  5. ➜  require-dictory git:(master) ✗ npm login
  6. Username: i5ting
  7. Password: 
  8. 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

  1. 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
