Pagination, Search, and Sorting

Pagination, Search, and Sorting

Backend

Query Parameters

All list endpoints accept:

• page (int, default: 1) — current page number
• pageSize (int, default: 10) — items per page
• search (string?, optional) — text to filter results
• sortBy (string, default varies) — field name to sort by
• sortDirection (string, default: "asc") — asc or desc

Default Sort Orders

• Patients: by lastName then firstName
• Doctors: by specialty then lastName
• Exams: by scheduledDate

Store Implementation

public (IReadOnlyList<T> Items, int TotalCount) GetPaged(int page, int pageSize, string sortBy, string sortDirection)
{
    var totalCount = _collection.Count();
    var items = ApplySort(_collection.FindAll(), sortBy, sortDirection)
        .Skip((page - 1) * pageSize).Take(pageSize).ToList();
    return (items, totalCount);
}

public (IReadOnlyList<T> Items, int TotalCount) SearchPaged(string search, int page, int pageSize, string sortBy, string sortDirection)
{
    var filtered = _collection.FindAll()
        .Where(item => /* case-insensitive string matching on relevant fields */)
        .ToList();
    var totalCount = filtered.Count;
    var items = ApplySort(filtered, sortBy, sortDirection)
        .Skip((page - 1) * pageSize).Take(pageSize).ToList();
    return (items, totalCount);
}

Response Structure

public record {Entity}ListResponse(
    IReadOnlyList<{Entity}Response> Items,
    PaginationInfo Pagination,
    SortInfo Sort,
    IReadOnlyList<Link> Links);

Pagination Links

Use PaginationLinks.Build(basePath, page, pageSize, totalPages, search, sortBy, sortDirection, additionalLinks).

Frontend

List Page Pattern

• State: page, pageSize, search, sortBy, sortDirection, data.
• Fetch with query params appended to the HATEOAS-discovered base URL.
• MUI TablePagination for page navigation.
• MUI TextField + Button for search input.
• MUI TableSortLabel on column headers for sort toggle.
• Clicking a column header cycles: default → asc → desc.
