Node Autoloader

A simple autoloader for node modules.

Install

Local:

npm install modload --save

Global:

npm install modload -g

Examples

• Require all files in a given directory and store the results in an array:

  const load = require('modload')
  
  const plugins = load.asArray({
    dir: path.join(__dirname, 'plugins')
  })
  
  server.register(plugins, (err) => {
    if (err) throw new Error(err)
  })

• Require all files in a given directory and store the results in an object whose structure matches the directory structure:

  const load = require('modload')
  
  const app = load.asObject({
    dir: path.join(__dirname, 'app')
  })

  If the directory structure looks like:

  ./
  |- app
  |- |- routes
  |- |- |- home.js
  |- |- |- login.js
  |- |- plugins
  |- |- |- auth.js

  Then the resulting object will match this structure:

  const app = {
    routes: {
      home: require('./app/routes/home.js'),
      login: require('./app/routes/login.js')
    },
    plugins: {
      auth: require('./app/routes/auth.js')
    }
  }

  This object can be attached to the global object via an optional argument.

API

Modload provides two methods, which both take an options object to configure their behaviour.

asArray(options)

Return

Array of required modules.

Parameters

options

Options object with the following fields:

dir

( String | required )

Root directory of files to require

include

( Array of RegExp | default: null )

RegExp patterns of files to include. Patterns are combined into a single regex pattern with OR. Exclude patterns take precedence over include patterns.

exclude

( Array of RegExp | default: null )

RegExp patterns of files to exclude. Patterns are combined into a single regex pattern with OR. Exclude patterns take precedence over include patterns.

stopfile

( String or RegExp | default: null )

A file in the directory tree matching this pattern is interpreted as the entry point for it's parent directory. Only this file is required; all other files in the same directory, and in sub-directories, are skipped.

es6modules

( Boolean | default: false )

A flag to specify whether modules are exported with ES6 module syntax (i.e. using the export keyword). If true, modload will require the default value (i.e., whatever is exported by export default)

modules

( Array of Strings | default: null )

Array of module names to load. Useful for loading third-party modules at the same time as your own modules. Loaded before custom modules. For example load.asArray({... modules: ['hapi']}) will load the hapi module before any others specified.

asObject(options)

Return

Object of module objects, structured to reflect directory structure.

Parameters

options

Options object with exactly the same fields as for the asArray method, but with the following additional fields:

isglobal

( Boolean | default: false )

If true, the returned object will also be attached to the global object under the key specified by the namespace parameter

namespace

( String | default: 'app' )

Specifies the key of the global object to which the object will be attached.
