All content covered in this post will only work with ESM

// In your first file:
import './example.js?abc=123';

// In your second file, example.js:
const url = new URL(import.meta.url);
const searchParam = url.searchParams.get('abc');

console.log(searchParam); // → '123'

file:///C:/Some/Folder/Path/example.js?abc=123

이것이 어떻게 사용될 수 있습니까?

설치

# install locally (recommended)
npm install dotenv --save

Or installing with yarn? yarn add dotenv

용법

Create a .env file in the root of your project:

S3_BUCKET="YOURS3BUCKET"
SECRET_KEY="YOURSECRETKEYGOESHERE"

As early as possible in your application, import and configure dotenv:

require('dotenv').config()
console.log(process.env) // remove this after you've confirmed it working

.. or using ES6?

import 'dotenv/config' // see https://github.com/motdotla/dotenv#how-do-i-use-dotenv-with-import
import express from 'express'

That's it. process.env now has the keys and values you defined in your .env file:

require('dotenv').config()
.

Instead of:

import dotenv from 'dotenv';
dotenv.config({ debug: true });

import 'dotenv/config?debug=true';
