dotnet-short_url

A C# port of https://github.com/Alir3z4/python-short_url

Excerpt from original project readme:

A bit-shuffling approach is used to avoid generating consecutive, predictable URLs. However, the algorithm is deterministic and will guarantee that no collisions will occur.

The URL alphabet is fully customizable and may contain any number of characters. By default, digits and lower-case letters are used, with some removed to avoid confusion between characters like o, O and 0. The default alphabet is shuffled and has a prime number of characters to further improve the results of the algorithm.

The intended use is that incrementing, consecutive integers will be used as keys to generate the short URLs. For example, when creating a new URL, the unique integer ID assigned by a database could be used to generate the URL by using this module. Or a simple counter may be used. As long as the same integer is not used twice, the same short URL will not be generated twice.

Installation

dotnet add package dotnet-short_url

Usage

Minimal console app example:

using System;
using ShortUrl;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            var encoder = new UrlEncoder();

            int id = 1;
            string key = encoder.EncodeUrl(id);
            Console.WriteLine(key);
            // "867nv"

            int decodedId = encoder.DecodeUrl("867nv");
            Console.WriteLine(decodedId);
            // 1
        }
    }
}
