directory-import v3.3.1

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 });
});

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);
