CoreOne.OQuery.Web

ASP.NET Core integration for CoreOne.OQuery. Automatically binds OQuery expressions from the request query string directly to controller action parameters — no manual parsing needed.

Install

dotnet add package CoreOne.OQuery.Web

Setup

Register the model binder in Program.cs:

builder.Services
    .AddControllers()
    .AddOQuery();          // <-- one line

Usage

Add a QueryNode parameter to any action. It is automatically populated from the query query string parameter:

using CoreOne.OQuery.Expressions;
using CoreOne.OQuery.Extensions;

[ApiController]
[Route("api/[controller]")]
public class TicketsController : ControllerBase
{
    private readonly AppDbContext _db;

    public TicketsController(AppDbContext db) => _db = db;

    [HttpGet]
    public IActionResult Get(QueryNode? query)
    {
        var results = _db.Tickets.Apply(query).ToList();
        return Ok(results);
    }
}

Example requests:

GET /api/tickets?query=status = "open" AND priority >= 3 LIMIT 20
GET /api/tickets?query=contains(assignee, "alice") SELECT assignee, priority PAGE 1 PAGESIZE 10
GET /api/tickets                              ← query is null, returns all records

Configuration

By default the binder reads from the query query string key. Change it via OQueryOptions:

builder.Services
    .AddControllers()
    .AddOQuery(options =>
    {
        options.QueryParameterName = "filter";   // now reads from ?filter=...
    });

Query Syntax Reference

Syntax Example
Equality status = "open"
Comparison priority >= 3
IN list label IN ("bug", "urgent")
AND / OR / NOT status = "open" AND NOT priority < 2
Nested property user.address.city = "Berlin"
contains() contains(assignee, "ali")
startsWith() startsWith(status, "op")
endsWith() endsWith(label, "ent")
SELECT projection status = "open" SELECT assignee, priority
Pagination LIMIT 20 OFFSET 0 or PAGE 2 PAGESIZE 25

See CoreOne.OQuery for the full query engine documentation.
