Quick Start

// Parse JSON from frontend
var request = QueryRequestParser.Parse(json);

// SqlKata
var result = new Query("products").ExecutePaged(db, request);

// EF Core
var result = await dbContext.Products.ExecutePagedAsync(request);

JSON:

{
  "filters": [
    { "field": "is_active", "operator": "Eq", "value": true },
    { "field": "price", "operator": "Gte", "value": 100 }
  ],
  "sort": [{ "field": "price", "direction": "Desc" }],
  "pagination": { "page": 1, "pageSize": 10 }
}

Response:

{
  "rows": [{ "id": 1, "name": "MacBook Pro", "price": 2499.99 }, ...],
  "total": 42,
  "page": 1,
  "pageSize": 10,
  "totalPages": 5,
  "hasNextPage": true
}

Package Downloads
Nedo.AspNet.Authorization

Authorization engine for ASP.NET Core: roles as a code-ring tree, organization scoping, per-page and per-field grants, row-level data filters with an expression language, delegations, and an admin API over the whole model. Table and column names are the host's to choose; migrations belong to the application, not to this package.
Nedo.AspNet.QueryEngine.ApiContracts

Bridge between Nedo.AspNet.ApiContracts and Nedo.AspNet.QueryEngine: maps the API-facing QueryRequest and PaginationQuery onto the engine's own request model. A separate package so the engine never depends on the API contracts, and an application that uses only one of the two takes only that one.
