NdjsonDelta

A .NET library to compute the delta (added, removed, changed objects) between two NDJSON (Newline Delimited JSON) files or strings. Designed for easy integration and NuGet distribution.

Features

  • Compare two NDJSON sources and get added, removed, and changed objects
  • Simple API for file or string input
  • Well-documented public methods

Usage

  1. Add the NuGet package to your project (instructions will be provided after publishing).
  2. Use the NdjsonDeltaCalculator class to compute deltas between NDJSON sources.

Sample Program

Suppose you have two NDJSON files:

file1.ndjson

{"id": 1, "name": "A"}
{"id": 2, "name": "B"}
{"id": 3, "name": "C"}

file2.ndjson

{"id": 1, "name": "A"}
{"id": 2, "name": "B2"}
{"id": 4, "name": "D"}

Sample C# code:

using System;
using System.Text.Json;
using NdjsonDelta;

class Program
{
    static void Main()
    {
        var calculator = new NdjsonDeltaCalculator();
        // Use a key selector for the unique key (e.g., "id")
        NdjsonDeltaResult result = calculator.ComputeDeltaFromFiles(
            "file1.ndjson", "file2.ndjson", obj => obj.GetProperty("id").GetInt32().ToString());

        Console.WriteLine("Added:");
        foreach (var item in result.Added)
            Console.WriteLine(item);

        Console.WriteLine("Removed:");
        foreach (var item in result.Removed)
            Console.WriteLine(item);

        Console.WriteLine("Changed:");
        foreach (var (oldObj, newObj) in result.Changed)
        {
            Console.WriteLine($"Old: {oldObj}");
            Console.WriteLine($"New: {newObj}");
        }
    }
}

Expected Output:

Added:
{"id":4,"name":"D"}
Removed:
{"id":3,"name":"C"}
Changed:
Old: {"id":2,"name":"B"}
New: {"id":2,"name":"B2"}
