# Path-to-RegExp
 | 
						|
 | 
						|
Turn an Express-style path string such as `/user/:name` into a regular expression.
 | 
						|
 | 
						|
**Note:** This is a legacy branch. You should upgrade to `1.x`.
 | 
						|
 | 
						|
## Usage
 | 
						|
 | 
						|
```javascript
 | 
						|
var pathToRegexp = require('path-to-regexp');
 | 
						|
```
 | 
						|
 | 
						|
### pathToRegexp(path, keys, options)
 | 
						|
 | 
						|
 - **path** A string in the express format, an array of such strings, or a regular expression
 | 
						|
 - **keys** An array to be populated with the keys present in the url.  Once the function completes, this will be an array of strings.
 | 
						|
 - **options**
 | 
						|
   - **options.sensitive** Defaults to false, set this to true to make routes case sensitive
 | 
						|
   - **options.strict** Defaults to false, set this to true to make the trailing slash matter.
 | 
						|
   - **options.end** Defaults to true, set this to false to only match the prefix of the URL.
 | 
						|
 | 
						|
```javascript
 | 
						|
var keys = [];
 | 
						|
var exp = pathToRegexp('/foo/:bar', keys);
 | 
						|
//keys = ['bar']
 | 
						|
//exp = /^\/foo\/(?:([^\/]+?))\/?$/i
 | 
						|
```
