Import all modules from a directory at once [NODE]

Question

MyApp
├── main.js
└── modules
    ├── a.js
    ├── b.js
    ├── c.js
    ├── d.js
    ├── e.js

In my NodeJS app, how can I import all my custom modules (a,b,c,d,e) in my main.js file at once?

I have long list of modules and I dont want to import them all separately.

Answer 1

Create an index.js in the modules/ folder:

const a = require('./a')
const b = require('./b')
const c = require('./c')
const d = require('./d')
const e = require('./e')

module.exports = {
  a,
  b,
  c,
  d,
  e
}

Then just import the module in main.js:

const modules = require('./modules')
modules.a

Alternatively you could loop through the directory and dynamically import each module.

Answer 2

You can dynamically import each module.

const fs = require('fs');

fs
  .readdirSync(`${__dirname}/modules`)
  .filter(file => (file.slice(-3) === '.js'))
  .forEach((file) => {
    require(`./modules/${file}`)
  });
