require-indexify

Description

A tool to automatically require modules in a directory.

Installation

$ npm i require-indexify

Usage

Say we have a diretory structure in our node project:

• app
  • controller
    • controllerA.js
    • controllerB.js
  • midlleware
    • middlewareA.js
    • middlewareB.js
  • util
    • funcA.js
    • funcB.js
    • ...
    • index.js
  • index.js

In general, app/util/index.js may be like this:

module.exports = {
  funcA: require('./funcA.js'),
  funcB: require('./funcB.js'),
  // ... and other modules in app/util
}

And, we have to manually add require when a new .js file is added.

Now with require-inedxify, app/util/index.js is much simpler:

module.exports = require('require-indexify')();

More options

indexify(basePath)

module.exports = indexify('./utl');
// or
module.exports = indexify(__dirname);

basePath can be either relative or absolute, default to '.'.

indexify(config) config.base: equivalent to basePath above.

config.include: an array explicitly specifying which module(s) to require. Default to none, all modules included.

config.exclude: an array explicitly specifying which module(s) not to require. Default to [], none is excluded.

config.recursive: whether to traverse the directory recursively requiring all valid modules. If a directory contains an index.js, it will not be further traversed. Default to false.

config.selfExclude: whether to exclude the file that is calling indexify. Default to true. This option is usefull since, in generall, we only want the index.js file to load its sibling modules.

config.merge: whether to merge all modules(Object.assign used). Default to false. Useful to require *.config.js and merge them into one.

example app/index.js:

module.exports = indexify({
  base: '.',
  include: [
    './controller',  // relative to base dir
    'util'
  ],
  exclude: [ 
    'controller/controllerA.js' // extname needed to indicate a file rather than a directory
  ],
  recursive: true
});
