| 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. | |

| ## Install | |
| ```bash | |
| npm install dotenv --save | |
| npm install dotenv-expand --save | |
| ``` | |
| ## Usage | |
| As early as possible in your application, require dotenv and dotenv-expand, and | |
| wrap dotenv-expand around dotenv. | |
| ```js | |
| var dotenv = require('dotenv') | |
| var dotenvExpand = require('dotenv-expand') | |
| var myEnv = dotenv.config() | |
| dotenvExpand(myEnv) | |
| ``` | |
| See [test/.env](./test/.env) for examples of variable expansion in your `.env` | |
| file. | |
