| # 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 | |
| ``` | |
