Masterly.NonEmptyList.EntityFrameworkCore

Entity Framework Core integration for Masterly.NonEmptyList. Provides value converters, comparers, and extension methods to seamlessly store and retrieve NonEmptyList<T> and ImmutableNonEmptyList<T> collections in your database.

Installation

dotnet add package Masterly.NonEmptyList.EntityFrameworkCore

Features

  • JSON Value Conversion: Store NonEmptyList<T> as JSON strings in the database
  • Change Tracking: Proper change detection with custom value comparers
  • Relationship Support: Configure one-to-many and many-to-many relationships
  • Validation Interceptor: Ensure non-empty constraints on save
  • Query Extensions: Convert query results to NonEmptyList<T>
  • Auto-Configuration: Convention-based setup for all properties

Quick Start

JSON Value Conversion

public class Product
{
    public int Id { get; set; }
    public string Name { get; set; }
    public NonEmptyList<string> Tags { get; set; } = new("default");
}

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Product>()
        .Property(p => p.Tags)
        .HasNonEmptyListConversion();
}

One-to-Many Relationships

modelBuilder.Entity<Order>()
    .HasNonEmptyManyWithOne(
        o => o.Items,
        i => i.Order,
        i => i.OrderId);

Query Extensions

NonEmptyList<Product> products = await context.Products
    .Where(p => p.IsActive)
    .ToNonEmptyListAsync();
