From 2b2eccfd1da15abba404d87449f467ede55836ae Mon Sep 17 00:00:00 2001 From: Kyle Mathews Date: Thu, 31 Jul 2025 15:31:31 -0600 Subject: [PATCH 1/2] Add comprehensive nested object query tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Added extensive test coverage for querying nested objects across all major query operations: ## Test Coverage Added ### basic.test.ts (6 new tests) - Querying nested object properties with WHERE clauses - Selecting nested object properties - Handling live updates to nested object properties - Spread operator usage with nested objects - Filtering based on deeply nested properties - Computed fields with nested properties ### where.test.ts (6 new tests) - Filtering by nested object properties and arrays - Null checks in nested properties - Combining nested and non-nested conditions - Live updates to nested properties - Computed expressions on nested properties - OR conditions with nested properties ### select.test.ts (7 new tests) - Selecting nested object properties - Selecting deeply nested properties - Spread operator with nested objects - Combining nested and computed properties - Nested arrays and objects with aliasing - Optional chaining with nested properties - Partial nested object selection ### order-by.test.ts (8 new tests) - Ordering by nested object properties (asc/desc) - Ordering by deeply nested properties - Multiple nested properties ordering - Ordering by coordinates (nested numeric) - Handling null/undefined nested properties - Live updates maintaining order - String ordering on nested properties ### group-by.test.ts (7 new tests) - Grouping by nested object properties - Grouping by deeply nested properties - Aggregation with nested properties - Multiple nested properties grouping - Boolean nested properties grouping - Conditional nested properties grouping - Live updates with nested group by ## Enhanced Data Models Updated all test data models with comprehensive nested structures: - User profiles with preferences and statistics - Address information with coordinates - Contact information with emergency contacts - Customer tier information with preferences - Shipping information with tracking details ## Current Test Status Total: 34 new tests added (1,563+ lines) Status: Tests currently fail due to incomplete nested object support in query compiler ### Known Issues Found - "Unknown expression type: undefined" errors for nested property access - Spread operators not supported on nested objects - Null coalescing operators not working in nested contexts - Optional chaining compilation issues These tests serve as a comprehensive specification for nested object querying functionality that needs to be implemented in the query compiler. 🤖

Subject: [PATCH 2/2] Add nested object query tests for TanStack DB MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Added comprehensive test coverage for querying nested objects across WHERE, SELECT, GROUP BY, and ORDER BY operations.
