urldiff v0.1.1

urldiff

URL difference processor, sorter and filter

About

urldiff is a library for parsing, diff'ing and scoring URLs based on their differences. These scores can then be used for comparing similar URLs and then sorting them within result sets.

Install by running npm install urldiff --save.

urldiff is designed to work on Node 6 and up.

Usage

The urldiff package provides a couple of methods for working with URLs and their scores. You can easily calculate the likeness score of 2 URLs by using calcuateURLScore:

const { calcuateURLScore } = require("urldiff");

const score = calcuateURLScore("http://somesite.com/test.html", "https://test.somesite.com/");
// `score` is a number between 0 and 1, where 1 is more similar

You can also sort an array of URLs or objects containing URLs:

const { sortByURL } = require("urldiff");

sortByURL(
    "https://test.com", // reference URL
    [
        { name: "two", url: "http://page.org/sub" },
        { name: "one", url: "http://test.com/page.html" }
    ], // Array of items to sort
    0, // Min diff score
    item => item.url // Getter to fetch the URL
);

// Output would be:
// [
//     { name: "one", url: "http://test.com/page.html" },
//     { name: "two", url: "http://page.org/sub" }
// ]
