|
Enabled is a small utility that can check if certain namespace are enabled by
|
|
environment variables which are automatically transformed to regular expressions
|
|
for matching.
|
|
|
|
## Installation
|
|
|
|
The module is release in the public npm registry and can be used in browsers and
|
|
servers as it uses plain ol ES3 to make the magic work.
|
|
|
|
```
|
|
npm install --save enabled
|
|
```
|
|
|
|
## Usage
|
|
|
|
First of all make sure you've required the module using:
|
|
|
|
```js
|
|
'use strict';
|
|
|
|
var enabled = require('enabled');
|
|
```
|
|
|
|
The returned `enabled` function accepts 2 arguments.
|
|
|
|
1. `name` **string**, The namespace that should match.
|
|
2. `pattern` **string**, The pattern that the name should satisfy
|
|
|
|
It will return a boolean indication of a match.
|
|
|
|
#### Examples
|
|
|
|
```js
|
|
var flag = 'foo';
|
|
|
|
enabled('foo', flag); // true;
|
|
enabled('bar', flag); // false;
|
|
|
|
//
|
|
// Use * for wild cards.
|
|
//
|
|
var wildcard = 'foob*';
|
|
|
|
enabled('foobar', wildcard); // true;
|
|
enabled('barfoo', wildcard); // false;
|
|
|
|
//
|
|
// Use - to ignore.
|
|
//
|
|
var ignore = 'foobar,-shizzle,nizzle';
|
|
|
|
enabled('foobar', ignore); // true;
|
|
enabled('shizzle-my-nizzle', ignore); // false;
|
|
enabled('nizzle', ignore); // true;
|
|
```
