Multiple Environments

Pass the --env-file flag (shorthand -f) to run any environment from a .env.environment file.

$ dotenv run --env-file=.env.production -- node index.js
[dotenv][INFO] Injecting 12 production environment variables into your application process

Combine multiple .env files if you like.

$ dotenv run --env-file=.env.local --env-file=.env -- node index.js

Usage

Guide

Begin by creating a simple 'hello world' program.

// index.js
console.log(`Hello ${process.env.HELLO}`)

Run it.

$ node index.js
Hello undefined

Run it with dotenv.

$ dotenv run -- node index.js
[dotenv@x.x.x][WARN] ENOENT: no such file or directory, open '/../../.env'
Hello undefined

It warns you when there is no .env file (pass the --quiet flag to suppress these warnings).

Create the .env file.

# env
JELLO="World"

Run it again.

$ dotenv run -- node index.js
[dotenv@x.x.x][INFO] Injecting 0 environment variables into your application process
Hello undefined

Hrm, still undefined. Pass the --debug flag to debug the issue. I'll give you a hint: 🍮

$ dotenv run --debug -- node index.js
[dotenv@x.x.x][VERBOSE] Loading env from /Users/scottmotte/Code/dotenv-org/temp/sandbox2/.env
[dotenv@x.x.x][DEBUG] Reading env from /Users/scottmotte/Code/dotenv-org/temp/sandbox2/.env
[dotenv@x.x.x][DEBUG] Parsing env from /Users/scottmotte/Code/dotenv-org/temp/sandbox2/.env
[dotenv@x.x.x][DEBUG] {"JELLO":"World"}

# Oops, HELLO not JELLO ^^

Fix your .env file.

# .env
HELLO="World"

One last time. Le tired.

$ dotenv run -- node index.js
[dotenv@x.x.x][INFO] Injecting 0 environment variables into your application process
Hello undefined

 

Install

Installing with brew is most straight forward:

brew install dotenv-org/brew/dotenv

Other Ways to Install

• After brew, installing globally using npm is easiest:

npm install @dotenv/dotenv --global

• Or use with npx:

npx @dotenv/dotenv help

• dotenv is a standalone binary, so (if you want) you can just download it directly:

# download it to `./dotenv`
curl -Lo ./dotenv --compressed -f --proto '=https' https://github.com/dotenv-org/dotenv/releases/latest/download/dotenv-$(uname)-$(uname -m).tar.gz

# install it to `/usr/local/bin/dotenv`
sudo install -m 755 dotenv /usr/local/bin

# check it works
dotenv --help
