[![dotenv-vault](https://badge.dotenv.org/works-with.svg?r=1)](https://www.dotenv.org/r/github.com/dotenv-org/dotenv-vault?r=1) # dotenv-expand

Dotenv-expand adds variable expansion on top of [dotenv](http://github.com/motdotla/dotenv). If you find yourself needing to expand environment variables already existing on your machine, then dotenv-expand is your tool. [![BuildStatus](https://img.shields.io/travis/motdotla/dotenv-expand/master.svg?style=flat-square)](https://travis-ci.org/motdotla/dotenv-expand) [![NPM version](https://img.shields.io/npm/v/dotenv-expand.svg?style=flat-square)](https://www.npmjs.com/package/dotenv-expand) [![js-standard-style](https://img.shields.io/badge/code%20style-standard-brightgreen.svg?style=flat-square)](https://github.com/feross/standard) [![Featured on Openbase](https://badges.openbase.com/js/featured/dotenv-expand.svg?token=BGZJQVRDGu24cWu/F8LIrCmZvIhC1yUc03IUkk9/sUM=)](https://openbase.com/js/dotenv-expand?utm_source=embedded&utm_medium=badge&utm_campaign=rate-badge) ## Install ```bash # Install locally (recommended) npm install dotenv-expand --save ``` Or installing with yarn? `yarn add dotenv-expand` ## Usage Create a `.env` file in the root of your project: ```dosini PASSWORD="s1mpl3" DB_PASS=$PASSWORD ``` As early as possible in your application, import and configure dotenv and then expand dotenv: ```javascript var dotenv = require('dotenv') var dotenvExpand = require('dotenv-expand') var myEnv = dotenv.config() dotenvExpand.expand(myEnv) console.log(process.env) ``` That's it. `process.env` now has the expanded keys and values you defined in your `.env` file. ### Preload You can use the `--require` (`-r`) [command line option](https://nodejs.org/api/cli.html#cli_r_require_module) to preload dotenv & dotenv-expand. By doing this, you do not need to require and load dotenv or dotenv-expand in your application code. This is the preferred approach when using `import` instead of `require`. ```bash $ node -r dotenv-expand/config your_script.js ``` The configuration options below are supported as command line arguments in the format `dotenv_config_
