dotenvdotenv

Zero-dependency lib that loads environment variables from .env.${ENV_NAME} files

Install

npm install dotenvdotenv --save

Usage

Require the lib as early as possible in your app

require('dotenvdotenv');

Create the .env.dev and .env.test files in the root directory and add environment variables on new lines as KEY=VALUE

For example:

REDIS_HOST=localhost
REDIS_PORT=32776

The vars are now available on process.env

redis: {
  host: process.env.REDIS_HOST,
  port: process.env.REDIS_PORT
}

If the .env.${ENV_NAME} files do no exist, an error will be raised

FAQ

Should I commit my .env.${ENV_NAME} files?

No. .env.${ENV_NAME} files should not be committed to version control. Your production environment should use the environment variables

What happens to existing environment variables?

Existing environment variables will not be overwritten
