url-value-parser

UrlValueParser

A helper ES6 class letting you extract values from URL paths, leaving the other parts untouched.

It uses an internal class ValueDetector determining what is a value and what is not. By default the following path chunks are considered values:

• decimal numbers
• strings in UUID format
• hex numbers consisting of 7 or more characters and consistent lower or upper case

You can customize all of the logic by providing options, overriding methods or providing your own value detector. See the source - it's easy, i promise.

Usage

const UrlValueParser = require('url-value-parser');
const parser = new UrlValueParser(/* {options} */);

parser.parsePathValues('/some/path/154/userId/ABC363AFE2');
/*
 here the values would be 154 and ABC363AFE2
 thus it returns:

  {
    chunks: ['some', 'path', '154', 'userId', 'ABC363AFE2'],
    valueIndexes: [2, 5]
  }
*/

parser.replacePathValues('/some/path/154/userId/ABC363AFE2', '#id');
// returns: /some/path/#id/userId/#id
