create-dotenv

dotenv

Written in typescript, full testing.

It can loads environment variables from a .env file into process.env or parse <key>=<value> string

Installation

npm i @jsdotenv/core

Usage

Add your application configuration to your .env file in the root of your project:

S3_BUCKET=YOURS3BUCKET
SECRET_KEY=YOURSECRETKEYGOESHERE

Then in your Nodejs app you can do something like

import dotenv from "@jsdotenv/core";

dotenv.load([__dirname + "/.env"]);
console.log(process.env["S3_BUCKET"]);

If you want to be really fancy with your env file you can do comments and exports (below is a valid env file)

# I am a comment and that is OK
SOME_VAR=someval
FOO=BAR # comments at line end are OK too
export BAR=BAZ

Or finally you can do YAML(ish) style

FOO: bar
BAR: baz

Multiple line is OK.

MULTI_DOUBLE_QUOTED="THIS
IS
A
MULTILINE
STRING"

Expand variables is OK.

OPTION_B=${OPTION_A}
OPTION_C=$OPTION_B
OPTION_D=${OPTION_A}${OPTION_B}
OPTION_E=${OPTION_NOT_DEFINED}

Command Mode

npm i create-dotenv -g

Usage

Execute commands using key-value pairs.

dotenv-cli -v KEY=VALUE -- bash -c 'echo "$BASIC"'

Execute commands using enviroment file.

dotenv-cli -e .env -- bash -c 'echo "$BASIC"'
