require.dir

documentation - install - why

Say we have the following tree

./folder
├── a.js
├── a.json
├── module
│   └── index.js
└── module.js

and each module exports its basename, i.e.

// ./folder/a.js
module.exports = 'a';

then

var requireDir = require('require.dir');
 
requireDir('./folder') // =>
{
  a: 'a',
  ajson: {
    a: 'a'
  },
  module: 'module',
  modulejs: 'module'
}

documentation

Require directories that may or may not have modules inside.

The basename of each file/module is used for the exported object. When in the given directory, if so happens, are files that have the same basename the extension is used for that key of the exported object.

Recurse folders if passed as an option.

The caller's path is always excluded.

Note that modules are not recursed.
Only folders that either do not have a package.json or an index file

spec

The module.exports a function

function requireDir([string dirname, object options])

arguments

• dirname, type string optional, directory to inspect and require

• options, type object optional, properties are:

  • dot whether to include pathnames starting with a .dot
  • test, type regexp, test each pathname found, that is not .dot
  • recursive, whether continue recursively on next folders

  defaults

  • dirname to the caller's directory

  when

  • options.dot is falsy dotfiles/folders are excluded
  • options.test is false that pathname is skipped

    require('./folder', {test: /\.js$/}) // js files

throws

• When the first dirname does not exists

returns

• object with all the exports

why

I've used require-dir but wanted to have it also return modules by default without recursing.

install

With npm

npm install --save require.dir

test

npm test

require.dir
  basic
    ✓ should return folder exports
  camelCase
    ✓ should camelCase folder exports
  recursive
    ✓ should recurse folder exports given {recursive: true}
  sameBasename
    ✓ should add lowerCase extension if basename existed
