directory-import

About

A module for the automatic import of files from a directory and its subdirectories (sync and async). The imported modules can be used either from the returned object or in the callback function.

---

Installation

npm install directory-import

After installation, you can use the module in your project:

const { directoryImport } = require('directory-import');

const importedModules = directoryImport('./path/to/directory');

// Outputs an object with imported modules
// For example: { modulePath1: module1, modulePath2: module2, ... }
console.log(importedModules);

or:

import { directoryImport } from 'directory-import';

const importedModules = directoryImport('./path/to/directory');

// Outputs an object with imported modules
// For example: { modulePath1: module1, modulePath2: module2, ... }
console.log(importedModules);

---

Simple usage

Here's a simple example of how to use the library and how it works under the hood:

const { directoryImport } = require('directory-import');

const importedModules = directoryImport('./sample-directory');

console.info(importedModules);

Path to directory from the GIF above

Invoking a callback on each file

This can be handy when, for instance, you need to perform a specific action based on the imported file.

const { directoryImport } = require('directory-import');

directoryImport('./sample-directory', (moduleName, modulePath, moduleData) => {
  console.info({ moduleName, modulePath, moduleData });
});

{Function} Callback properties:

Property	Type	Description
name	String	Module name based on the filename
path	String	Relative module path
data	String	Exported data from the module. (Ex: "module.exports = 'test'")
index	Number	Index of the imported module

{Object} Options properties:

Property	Type	Description
includeSubdirectories	Boolean	If true, the module will import files from subdirectories
targetDirectoryPath	String	The path to the directory from which modules are to be imported
importPattern	RegExp	RegExp pattern to filter files
importMode	String	The import mode. Can be 'sync' or 'async'
limit	Number	Limit the number of imported modules

More examples:

Minimum code needed for use:

const { directoryImport } = require('directory-import');

// Synchronously imports all modules in the same directory from which the code was called
directoryImport();

Asynchronously import files from the specified directory:

const { directoryImport } = require('directory-import');

const result = directoryImport('./path/to/directory', 'async');

// Promise { <pending> }
console.log(result);

Put the result in a variable and invoke a callback on each file:

const { directoryImport } = require('directory-import');

const importedModules = directoryImport('./path/to/directory', (moduleName, modulePath, moduleData) => {
  // {
  //   moduleName: 'sample-file-1',
  //   modulePath: '/sample-file-1.js',
  //   moduleData: 'This is first sampleFile'
  // }
  // ...
  console.info({ moduleName, modulePath, moduleData });
});

// {
//   '/sample-file-1.js': 'This is first sampleFile',
//   ...
// }
console.info(importedModules);
