RavenDB.Specifications 🚀

NuGet License: MIT

A robust library implementing the Specification Design Pattern specifically for RavenDB. Decentralize your business logic from data access infrastructure with reusable, testable, and combinable queries.

🚀 Key Features

Feature Description
Search Abstraction Automatically converts Contains criteria to RavenDB's .Search() API for optimized full-text matching.
Rich Operators Built-in support for Equal, NotEqual, GreaterThan, LessThan, In, Between, etc.
Logical Composition Easily combine multiple business rules using And, Or, and Not methods.
SQL-to-Spec Parse simple SQL-like strings into Specification objects for dynamic filtering.
RavenDB Native Deep integration with IAsyncDocumentSession and IDocumentSession.

🛠️ Usage Example

1. Define Business Rules

public class ActivePremiumProductsSpec : Specification<Product>
{
    public override Expression<Func<Product, bool>> ToExpression()
    {
        return p => p.IsActive && p.Price > 100;
    }
}

// Or use built-in ones:
var brandSpec = new EqualSpecification<Product>("Brand", "Dell");
var searchSpec = new ContainsSpecification<Product>("Name", "Monitor");

2. Combine and Execute

var finalSpec = brandSpec.And(searchSpec).Or(new ActivePremiumProductsSpec());

using var session = documentStore.OpenAsyncSession();
var results = await Queries<Product>
    .Filter(session, finalSpec)
    .ToListAsync();

🔍 SQL-to-Specification

Convert dynamic SQL filter strings into strongly-typed specifications. Supports AND, OR, NOT, IN, IS NULL, and LIKE (with % wildcards).

string sql = "Brand = 'Dell' AND (Price < 1000 OR Category IN ('Electronics', 'IT')) AND Name LIKE '%Monitor%'";
var spec = SqlToSpecificationConverter.Convert<Product>(sql);

var products = await Queries<Product>.Filter(session, spec).ToListAsync();
