Path-to-RegExp

Turn an Express-style path string such as /user/:name into a regular expression.

Usage

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.

var keys = [];
var exp = pathToRegexp('/foo/:bar', keys);
//keys = ['bar']
//exp = /^\/foo\/(?:([^\/]+?))\/?$/i
