FlexQuery.NET

Dynamic filtering, sorting, paging, and projection for IQueryable in .NET.

FlexQuery.NET is a lightweight and powerful dynamic query engine for .NET. It allows you to transform complex API query parameters into optimized, EF Core-translatable expression trees with a single line of code.

⚡ Key Features

Dynamic Querying: Powerful DSL, JQL, and JSON-based filtering.
IQueryable-Native: 100% server-side translation—no client-side evaluation.
Advanced Projection: Automatic SQL SELECT optimization including nested includes.
Governance & Security: Built-in field-level validation and operator restrictions.
High Performance: Thread-safe expression caching for ultra-low latency.
Explicit Joins: SQL-like join support with alias-aware field resolution.

🚀 Quick Start

1. Installation

dotnet add package FlexQuery.NET
dotnet add package FlexQuery.NET.EFCore
dotnet add package FlexQuery.NET.AspNetCore

2. Simple Usage

Securely execute a dynamic query directly from your controller:

[HttpGet]
public async Task<IActionResult> GetUsers([FromQuery] FlexQueryParameters parameters)
{
    // One-stop shop: Parsing + Validation + Execution
    var result = await _context.Users.FlexQueryAsync(parameters, options => 
    {
        options.AllowedFields = ["Id", "Name", "Email", "Status"];
        options.AllowOperators("Status", FilterOperators.Eq, FilterOperators.In);
    });

    return Ok(result);
}

3. Example Request

GET /api/users?filter=age:gt:18&sort=createdAt:desc&page=1&pageSize=20&select=id,name,email
