RabStack Query DevTools

Core DevTools engine for RabStack Query. Observes cache events and builds displayable snapshots of query and mutation state.

This package provides the platform-agnostic CacheObserver and display models. For a ready-to-use UI, install one of:

Installation

dotnet add package RabstackQuery.DevTools

Usage

var observer = new CacheObserver(queryClient, new DevToolsOptions());

observer.SnapshotsChanged += () =>
{
    foreach (var query in observer.Queries)
    {
        Console.WriteLine($"[{query.DisplayStatus}] {query.QueryHash} — observers: {query.ObserverCount}");
    }

    foreach (var mutation in observer.Mutations)
    {
        Console.WriteLine($"[{mutation.Status}] {mutation.MutationId}");
    }
};

// Don't forget to dispose when done
observer.Dispose();

Key Types

Type Description
CacheObserver Subscribes to QueryCache and MutationCache events, rebuilds snapshots on a debounced interval (250ms)
QueryListItem Display model for a single query: hash, key, status, observer count, last update time
MutationListItem Display model for a single mutation: ID, status, variables
QueryDisplayStatus Status classification: Fresh, Stale, Fetching, Paused, Inactive, Error
DevToolsOptions Configuration including DataFormatter (custom serialization for display) and DevToolsColorValues
SortOption Built-in and custom sort configurations

Building a Custom UI

Use this package directly to build DevTools integrations for platforms beyond Blazor and MAUI. The CacheObserver exposes:

  • Queries / Mutations — current snapshot lists
  • QueryCount — total tracked queries
  • SnapshotsChanged — event fired when snapshots are rebuilt
  • FindQueryByHash(string) — look up the underlying Query for detail views
  • ForceRefresh() — trigger an immediate snapshot rebuild
