@socheatsok78/webenv

Loads variables from .env for web projects.

Story

What is Dotenv?

Dotenv is a zero-dependency module that loads environment variables from a .env file into process.env. Storing configuration in the environment separate from code is based on The Twelve-Factor App methodology.

Why Webenv?

While dotenv provide a convenient way of loading environment variables from a .env file for Node.js, however managing runtime environment variables for the web doesn't seem to be any easier.

This project is aimed to fix the those on the web by providing a wrapper to dotenv using fetch to make a request for .env file from your publicly accessible path. It is a highly customized dotenv and dotenv-expand built for the web.

Install

npm install @socheatsok78/webenv --save

Or installing with yarn?

yarn add @socheatsok78/webenv

Usage

Create a .env file in the public folder of your project:

# Please DO NOT store your sensitive data here
# This file must be publicly accessible by anyone
API_BACKEND_ENDPOINT="https://api.example.com"

NOTE:

The webenv do not have access to the server environment variables. You can consider that the webenv is only use for runtime configuration only.

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

import * as webenv from '@socheatsok78/webenv'

(async () => {
    await webenv.config({ path: '/.env' }) // make a fetch request to '/.env' and parse the string response
    console.log(window.env) // remove this after you've confirmed it working
})()
