  _{Coded with ❤️ by Simone Primarosa.}



## Background

This package aim to let you access to your environment variables as if they were JavaScript object.

See [this guide][12factorsguide] to understand how to use this package to create a [12 Factor compliant][12factors] configuration system for you app.

## Install

```

$ npm install --save env-dot-prop

```

## Usage

```js

const envDotProp = require('env-dot-prop');

// Let's assume process.env contains the following keys

process.env = {

  FOO_BAR: 'unicorn',

  'FOO_DOT.DOT': 'pony',

  'FOO_UND\\_UND': 'whale'

};

console.log(process.env);

// => { FOO_BAR: 'unicorn', 'FOO_DOT.DOT': 'pony', 'FOO_UND\_UND': 'whale' }

envDotProp.get('');

// => { foo: { bar: 'unicorn', 'dot.dot': 'pony', und_und: 'whale' } }

// getter

envDotProp.get('foo.bar');

// => 'unicorn'

envDotProp.get('foo.notDefined.deep');

// => undefined

envDotProp.get('foo.notDefined.deep', 'default value');

// => 'default value'

envDotProp.get('foo.dot\\.dot');

// => 'pony'

// setter

envDotProp.set('foo.bar', 'b');

envDotProp.get('foo.bar');

// => 'b'

envDotProp.get('');

// => { foo: { bar: 'b', 'dot.dot': 'pony', und_und: 'whale' } }

envDotProp.set('foo.baz.e', 'x');

envDotProp.get('foo.baz.e');

// => 'x'

envDotProp.get('foo.baz');

// => { e: 'x' }

envDotProp.get('');

// => { foo: { bar: 'b', baz: { e: 'x' }, 'dot.dot': 'pony', und_und: 'whale' } }

// has

envDotProp.has('foo.bar');

// => true

// deleter

envDotProp.delete('foo.bar');

envDotProp.get('foo');

// => { baz: { e: 'x' }, 'dot.dot': 'pony', und_und: 'whale' }

envDotProp.delete('foo.baz.e');

envDotProp.get('foo.baz');

// => undefined

envDotProp.set('n1', 42, {stringify: false});

envDotProp.get('n1', {parse: false});

// => 42

envDotProp.get('n1', {parse: true});

// => 42

envDotProp.set('n2', 42, {stringify: true});

envDotProp.get('n2', {parse: false});

// => '42'

envDotProp.get('n2', {parse: true});

// => 42

envDotProp.set('n3', 42);

envDotProp.get('n3');

// => 42

envDotProp.set('n4', '42');

envDotProp.get('n4');

// => '42'

envDotProp.get('');

// => { n1: '42', n1: 42, n3: 42, n4: '42', foo: { 'dot.dot': 'pony', und_und: 'whale' } }

console.log(process.env);

// => { 'FOO_DOT.DOT': 'pony', 'FOO_UND\_UND': 'whale', N1: '42', N2: 42, N3: 42, N4: '42' }

```

## API



## get(path, [defaultValue], [opts]) ⇒ any

Gets the values of environment variables at the path specified.

**Kind**: global function  

**Returns**: any - The values of environment variables associated with the path specified.  

**Access**: public  

| Param | Type | Default | Description |

| --- | --- | --- | --- |

| path | string |  | Dot separated path. |

| [defaultValue] | any |  | Default value to return if there is not any environment variable that matches the path provided. |

| [opts] | Object |  | Additional options. |

| [opts.parse] | boolean | false | If true the value retrieved is converted to the proper type. |

| [opts.caseSensitive] | boolean | false | If true no case conversion will be performed from the dot path provided to the env key search. Eg: 'tesT.kEy' will look for tesT_kEy environment variable instead of TEST_KEY. |



## set(path, value, [opts])

Sets an env key at the path specified. If nested keys are present they will

be deleted.

**Kind**: global function  

**Access**: public  

| Param | Type | Default | Description |

| --- | --- | --- | --- |

| path | string |  | Dot separated path. |

| value | string |  | Value to set. |

| [opts] | object |  | Additional options. |

| [opts.stringify] | boolean | false | If true the value provided is converted to string. |

| [opts.caseSensitive] | boolean | false | If true no case conversion is performed from the dot path provided to the env key search. Eg: 'tesT.kEy' will look for tesT_kEy environment variable instead of TEST_KEY. |



## del(path, [opts])

Deletes an env key at the path specified.

If nested keys are present they will be deleted too.

**Kind**: global function  

**Access**: public  

| Param | Type | Default | Description |

| --- | --- | --- | --- |

| path | string |  | A dot separated path. |

| [opts] | object |  | Additional options. |

| [opts.caseSensitive] | boolean | false | If true no case conversion is performed from the dot path provided to the env key search. Eg: 'tesT.kEy' will look for tesT_kEy environment variable instead of TEST_KEY. |



## has(path, [opts]) ⇒ boolean

Returns whether an env key exists at the path specified.

**Kind**: global function  

**Returns**: boolean - true if exists at least one environment variables with that

path prefix.  

**Access**: public  

| Param | Type | Default | Description |

| --- | --- | --- | --- |

| path | string |  | Dot separated path. |

| [opts] | object |  | Additional options. |

| [opts.caseSensitive] | boolean | false | If true no case conversion is performed from the dot path provided to the env key search. Eg: 'tesT.kEy' will look for tesT_kEy environment variable instead of TEST_KEY. |
