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.
