Package Exports

url-value-parser

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (url-value-parser) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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
long base64 encoded strings
JSON Web Tokens (JWT)

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

Options

replaceMasks - use custom masks instead of built-in
extraMasks - add your custom masks additionally to the built-in ones
minHexLength - when using built-in masks, count only long enough HEX values, DEFAULT: 7
minBase64Length - when using built-in masks, count only long enough base64 values, DEFAULT: 66

If strings are provided in an array to replaceMasks and extraMasks, then they're automatically converted into RegExp

Example:

const parser = new UrlValueParser({
  minHexLength: 4,
  extraMasks: [
    /^z_.*$/,
    '^[0-9]+\\.[0-9]+$'
  ]
});
