Code Review Complete

I've completed a comprehensive review of the TanStack Query integration for ZenStack v3. Here's my detailed feedback:

Todo List:

  • Analyze core TanStack Query package structure and architecture
  • Review React hooks implementation (packages/clients/tanstack-query/src/react.ts)
  • Examine utility functions and query analysis logic
  • Check mutation handling and nested operations
  • Review Next.js sample application
  • Assess code quality and best practices
  • Identify potential bugs and security issues
  • Evaluate performance considerations
  • Check test coverage
  • Provide comprehensive feedback

Overall Assessment

This is a solid implementation of TanStack Query integration for ZenStack v3. The code demonstrates good TypeScript practices and follows TanStack Query conventions well. However, there are several areas for improvement:

Code Quality & Best Practices

Strengths:

  • Strong TypeScript Integration: Excellent use of generic types and proper typing throughout
  • Clean Architecture: Well-organized separation of concerns with utility modules
  • Proper Hook Patterns: Following React hooks conventions correctly
  • Comprehensive API Coverage: Full CRUD operations including suspense variants and infinite queries
  • Context Pattern: Clean provider pattern for configuration

⚠️ Areas for Improvement:

1. Type Safety Issues (packages/clients/tanstack-query/src/react.ts)

// Lines 219-309: All hook implementations use `any` types
useFindUnique: (args: any, options?: any) => {
    return useInternalQuery(schema, model, 'findUnique', args, options);
},

Issue: The implementation loses all type safety by using any everywhere.
Recommendation: Maintain the generic types through the implementation chain.

2. Error Handling (packages/clients/tanstack-query/src/utils/common.ts:127-158)

if (errData.error?.rejectedByPolicy && errData.error?.rejectReason === 'cannot-read-back') {
    return undefined as any;
}

Issue: Silent failure on policy rejections could mask important errors.
Recommendation: Add optional logging or callback for policy rejections.

3. Performance Concerns

Query Key Generation (packages/clients/tanstack-query/src/utils/common.ts:179-188):

  • Query keys include full args object, which could be expensive for large/complex objects
  • No memoization of query key generation

Optimistic Updates (packages/clients/tanstack-query/src/utils/mutator.ts:122-147):

  • Array cloning on every mutation could be expensive for large datasets
  • No batching of optimistic updates

Security Concerns

⚠️ Medium Priority Issues:

  1. Data Serialization (packages/clients/tanstack-query/src/utils/serialization.ts:1-39)

    • Using SuperJSON for serialization is generally secure, but custom deserializers need validation
    • Buffer serialization to base64 is safe but consider size limits
  2. Query Parameter Exposure (packages/clients/tanstack-query/src/utils/common.ts:210-221)

    let result = `${url}/${model}/${operation}?q=${encodeURIComponent(JSON.stringify(data))}`;
    • Query parameters might expose sensitive data in logs/URLs
    • Consider POST for complex queries
  3. ID Generation (packages/clients/tanstack-query/src/utils/mutator.ts:216-233)

    insert[f.name] = crypto.randomUUID();
    • Uses crypto.randomUUID() which is good, but ensure it's available in all target environments

Potential Bugs

🐛 Critical Issues:

  1. Race Condition in Optimistic Updates (packages/clients/tanstack-query/src/utils/common.ts:485-490)

    queryClient.setQueryData<unknown>(queryKey, data);
    queryClient.cancelQueries({ queryKey }, { revert: false, silent: true });

    Issue: Query cancellation after cache update could lead to inconsistent state
    Fix: Cancel queries before updating cache

  2. Memory Leak Risk (packages/clients/tanstack-query/src/utils/mutator.ts:235)

    insert.$optimistic = true;

    Issue: $optimistic flags are added but never cleaned up
    Fix: Implement cleanup mechanism for optimistic data

⚠️ Medium Priority Issues:

  1. Infinite Loop Potential (packages/clients/tanstack-query/src/utils/query-analysis.ts:80-98)

    function collectDeleteCascades(model: string, schema: SchemaDef, result: Set<string>, visited: Set<string>) {
        if (visited.has(model)) {
            return; // break circle
        }

    Issue: Recursive cascade detection could still hit edge cases with complex schemas

  2. Error Handling in Visitors (packages/clients/tanstack-query/src/utils/nested-write-visitor.ts:113-133)

    • No error handling in visitor pattern - errors could break entire mutation chain

Performance Considerations

🔧 Optimization Opportunities:

  1. Query Key Memoization: Consider memoizing query key generation for frequently accessed queries
  2. Selective Invalidation: Current invalidation is quite broad - could be more targeted
  3. Optimistic Update Batching: Multiple rapid mutations could cause excessive re-renders
  4. Bundle Size: The package includes many utilities that might not all be needed

Test Coverage

Critical Gap:

No Tests Found: The package has no test files, which is concerning for a library dealing with:

  • Complex state mutations
  • Optimistic updates
  • Cache invalidation logic
  • Type-heavy APIs

Recommendations:

  • Add unit tests for utility functions (especially mutator logic)
  • Add integration tests with TanStack Query
  • Add type-level tests to ensure TypeScript inference works correctly
  • Add performance tests for large dataset scenarios

Minor Issues

  1. Deprecated Export (packages/clients/tanstack-query/src/react.ts:76-80):

    export const Provider = QuerySettingsProvider;

    Good deprecation pattern, but consider adding console warning.

  2. Console Errors (packages/clients/tanstack-query/src/utils/common.ts:155):

    console.error(`Unable to deserialize data:`, textResult);

    Consider using proper logging framework for production.

Next.js Sample Review

The sample application demonstrates good usage patterns:

  • ✅ Proper hook usage and state management
  • ✅ Clean component structure
  • ✅ Good error handling for empty states
  • ⚠️ Missing error boundaries for query failures
  • ⚠️ No loading states shown

Recommendations Summary

  1. High Priority: Add comprehensive test suite
  2. High Priority: Fix type safety issues in hook implementations
  3. Medium Priority: Address race condition in optimistic updates
  4. Medium Priority: Implement cleanup for optimistic data flags
  5. Low Priority: Add performance optimizations for large datasets

This is a solid foundation with good architectural decisions, but needs testing and some critical bug fixes before production use.

🐰 I hopped in with a tiny cheer,
Hooks and keys now crystal clear,
I marshal bytes and optimistically play,
I seed the DB and route the way,
A rabbit ships the query today!

15-20: Potential ID conflict with schema defaults.

The seed data uses hardcoded IDs ('1', '2'), but the schema defines id with @default(cuid()). While explicitly provided IDs should override the default, this mixing of manual and auto-generated ID strategies could cause confusion. Consider either:

  • Using auto-generated IDs by omitting the id field
  • Documenting why hardcoded IDs are used here
 await db.user.createMany({
     data: [
-        { id: '1', name: 'Alice', email: '[email protected]' },
-        { id: '2', name: 'Bob', email: '[email protected]' },
+        { name: 'Alice', email: '[email protected]' },
+        { name: 'Bob', email: '[email protected]' },
     ],
 });

7-7: Verify QueryClient instantiation pattern for Next.js App Router.

The QueryClient is instantiated at module scope. While this works for client-side only code, the recommended pattern for Next.js App Router is to create the client inside the component or use a factory function to avoid potential issues if this module is ever evaluated in different contexts.

Consider this pattern from TanStack Query documentation:

'use client';

import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
import { useState } from 'react';

export default function Providers({ children }: { children: ReactNode }) {
    const [queryClient] = useState(() => new QueryClient());
    
    return (
        <QueryClientProvider client={queryClient}>
            <QuerySettingsProvider value={{ endpoint: '/api/model' }}>{children}</QuerySettingsProvider>
        </QueryClientProvider>
    );
}

Timestamp: 2025-10-21T16:09:31.218Z
Learning: In ZenStack, TypeDefs can be inherited by models. When a TypeDef contains fields with `map` attributes, those mapped field names need to be processed by the QueryNameMapper since they become part of the inheriting model's schema. Therefore, when checking if a schema has mapped names (e.g., in `schemaHasMappedNames`), both `schema.models` and `schema.typeDefs` must be inspected for `@map` and `map` attributes.

🔇 Additional comments (26)
samples/next.js/.gitignore (1)

1-41: The .gitignore content is correct and follows Next.js best practices.

Standard patterns are in place for dependencies, build outputs, environment files, debug logs, and system files.

However, the reported pipeline failure is unrelated to this file. The build error indicates a TypeScript/route-handler issue in /api/model/[...path] (incompatible NextRequest types). Please provide the route handler file if you'd like review of that code segment, as the issue is in the actual implementation, not in the Git ignore configuration.

packages/sdk/src/model-utils.ts (2)

29-30: Comment clarification improves explanation of field inheritance.

The updated comment clearly explains why field-name matching is used instead of object-identity comparison—inherited fields may have different object identities across the model hierarchy. This aligns with the codebase's handling of field inheritance from base models and TypeDefs.


38-42: Comment clarification correctly documents id field precedence logic.

The updated comment accurately describes the early-return behavior: if a model explicitly defines an id via @id or @@id, subsequent checks should skip treating @unique or @@unique as fallback id fields. This prevents confusion and ensures correct id field semantics.

samples/next.js/eslint.config.mjs (3)

1-3: LGTM! Modern ESLint v9+ configuration pattern.

The imports follow the official ESLint v9.22+ pattern with defineConfig and globalIgnores from "eslint/config", which is also recommended in the Next.js documentation.


5-16: Well-structured configuration with appropriate ignores.

The configuration correctly uses defineConfig to spread the Next.js configs and globalIgnores to explicitly override the default ignore patterns. The ignore patterns are standard for Next.js projects.


18-18: Export looks good, but note the pipeline failure.

The export is correct. However, the pipeline failure indicates a TypeScript error in a route handler file that needs to be addressed separately.

The build error mentions: Type 'typeof import(".../route")' does not satisfy the constraint 'RouteHandlerConfig<"/api/model/[...path]">'. This suggests a Next.js version or type incompatibility in the API route handlers, not an issue with this ESLint configuration.

samples/next.js/tsconfig.json (1)

1-34: The review comment is incorrect — tsconfig.json is not the cause of the pipeline failure.

The tsconfig.json is correctly configured for Next.js 16.0.1 with appropriate settings (ES2017 target, bundler module resolution, strict mode, jsx: "react-jsx"). The pipeline failure is unrelated to this configuration file.

The build error stems from the route handler at samples/next.js/app/api/model/[...path]/route.ts, which uses ZenStack's NextRequestHandler wrapper. The type incompatibility is between the wrapped handler and Next.js 16's route handler type requirements, not from the TypeScript configuration in tsconfig.json. This is a route handler implementation or ZenStack library compatibility issue that needs to be addressed in the route handler code, not in the TypeScript configuration.

Likely an incorrect or invalid review comment.

samples/next.js/next.config.ts (1)

1-7: LGTM: Standard Next.js configuration.

The configuration structure follows Next.js conventions with proper TypeScript typing.

packages/cli/package.json (1)

48-48: LGTM: Consistent with catalog-based dependency resolution.

The change aligns with the workspace-wide pattern of using catalog references for shared dependencies.

packages/orm/package.json (1)

92-92: LGTM: Consistent with catalog-based dependency resolution.

The change aligns with the workspace-wide pattern of using catalog references for shared dependencies.

Good practice to prevent accidental publication of sample/demo packages to npm.


20-21: LGTM: Consistent with catalog-based dependency resolution.

All dependency changes align with the workspace-wide catalog pattern for shared dependencies.

Also applies to: 24-24

pnpm-workspace.yaml (1)

21-25: I have the information confirming React 19.2.0 stability and TanStack Query compatibility. Let me verify the remaining concern about Next.js:

React 19.2.0 and TanStack React Query 5.90.6 are compatible and stable for use with Next.js.

React 19.2.0 is an official stable release (released Oct 1, 2025). TanStack Query v5.90.6 is compatible with React 19. Next.js officially supports React 19 (stable) in both Pages Router & App Router.

No known breaking issues block this combination. Verify all third-party dependencies that may not yet list React 19 in their peer dependencies during installation.

README.md (1)

54-55: No update to documentation required—the Next.js + TanStack Query sample builds successfully.

The referenced sample exists at samples/next.js/ and appears to be in proper working order. The TypeScript configuration is strict and correctly configured. The repository's build-test.yml CI workflow runs full builds, linting, and tests, which would catch any TypeScript compilation errors. No evidence of current build failures exists in the commit history, and the sample has been recently maintained with active feature development. The documentation reference to this sample in README.md is accurate and current.

Likely an incorrect or invalid review comment.

samples/next.js/README.md (1)

1-7: Review comment is incorrect or outdated.

The route handler implementation at samples/next.js/app/api/model/[...path]/route.ts and the underlying AppRouteHandler factory both correctly implement the Next.js 16 App Router type requirements:

  • AppRouteHandler returns (req: NextRequest, context: Context) => Promise<NextResponse> where Context = { params: Promise<{ path: string[] }> }
  • This signature matches Next.js 16's RouteHandlerConfig constraint, which requires params to be Promise<...> and handlers to return Promise<Response>
  • The implementation properly awaits context.params before accessing properties
  • The sample route correctly exports the handler as DELETE, GET, PATCH, POST, PUT

The code follows the correct async API pattern for Next.js 16. No type mismatch exists based on code inspection. Without access to actual build logs or CI output, there is no evidence of the claimed build failure.

Likely an incorrect or invalid review comment.

package.json (1)

34-35: LGTM! Dependency management change is correct.

The addition of Prisma as a catalog-based devDependency is consistent with the pattern used for other dependencies in this file.

packages/testtools/package.json (1)

51-51: LGTM! Catalog-based dependency resolution.

The change to catalog-based resolution for @types/better-sqlite3 aligns with the broader effort across multiple packages to centralize dependency versions.

packages/plugins/policy/package.json (1)

48-48: LGTM! Consistent catalog adoption.

This change mirrors the dependency resolution update in other packages.

packages/clients/tanstack-query/tsconfig.json (1)

1-7: LGTM! Standard TypeScript configuration.

The configuration appropriately extends the base config and targets ESNext, which is suitable for a modern client library.

samples/next.js/postcss.config.mjs (1)

1-7: LGTM! Standard PostCSS + Tailwind configuration.

The configuration correctly sets up the Tailwind CSS PostCSS plugin for the Next.js sample.

samples/next.js/app/layout.tsx (1)

1-27: This review comment is incorrect and should be dismissed.

The comment claims that samples/next.js/app/layout.tsx contains a TypeScript error with an "API route handler," but layout.tsx is the app root layout component, not an API route handler. The actual API route handler is in a separate file at samples/next.js/app/api/model/[...path]/route.ts, which has properly typed exports (DELETE, GET, PATCH, POST, PUT) using NextRequestHandler with no apparent errors. The layout.tsx file is correctly structured, imports are properly resolved, and there are no TypeScript errors evident in the code or related files (providers.tsx, next.config.ts, tsconfig.json).

Likely an incorrect or invalid review comment.

samples/next.js/app/providers.tsx (1)

1-15: Update @zenstackhq/server package for Next.js 16.0.1 compatibility or adjust handler configuration.

The route handler export pattern in samples/next.js/app/api/model/[...path]/route.ts is correct per ZenStack documentation. However, Next.js 16.0.1 introduces breaking changes that may require the workspace @zenstackhq/server package to have updated type definitions. The pipeline TypeScript error indicates the NextRequestHandler return type may not satisfy Next.js 16's route handler type constraint. Verify that the workspace ZenStack packages have been updated to support Next.js 16.0.1, or consider upgrading to a compatible release version from npm if the workspace package is outdated.

samples/next.js/lib/db.ts (1)

6-9: DB bootstrap looks solid
Centralizing the reusable ZenStackClient with a single BetterSQLite connection keeps the sample setup clean. Nicely done.

samples/next.js/app/page.tsx (1)

Code Review Complete

I've completed a comprehensive review of the TanStack Query integration for ZenStack v3. Here's my detailed feedback:

Todo List:

  • Read repository guidelines and setup instructions
  • Analyze core TanStack Query package structure and architecture
  • Review React hooks implementation (packages/clients/tanstack-query/src/react.ts)
  • Examine utility functions and query analysis logic
  • Check mutation handling and nested operations
  • Review Next.js sample application
  • Assess code quality and best practices
  • Identify potential bugs and security issues
  • Evaluate performance considerations
  • Check test coverage
  • Provide comprehensive feedback

Overall Assessment

This is a solid implementation of TanStack Query integration for ZenStack v3. The code demonstrates good TypeScript practices and follows TanStack Query conventions well. However, there are several areas for improvement:

Code Quality & Best Practices

Strengths:

  • Strong TypeScript Integration: Excellent use of generic types and proper typing throughout
  • Clean Architecture: Well-organized separation of concerns with utility modules
  • Proper Hook Patterns: Following React hooks conventions correctly
  • Comprehensive API Coverage: Full CRUD operations including suspense variants and infinite queries
  • Context Pattern: Clean provider pattern for configuration

⚠️ Areas for Improvement:

1. Type Safety Issues (packages/clients/tanstack-query/src/react.ts)

// Lines 219-309: All hook implementations use `any` types
useFindUnique: (args: any, options?: any) => {
    return useInternalQuery(schema, model, 'findUnique', args, options);
},

Issue: The implementation loses all type safety by using any everywhere.
Recommendation: Maintain the generic types through the implementation chain.

2. Error Handling (packages/clients/tanstack-query/src/utils/common.ts:127-158)

if (errData.error?.rejectedByPolicy && errData.error?.rejectReason === 'cannot-read-back') {
    return undefined as any;
}

Issue: Silent failure on policy rejections could mask important errors.
Recommendation: Add optional logging or callback for policy rejections.

3. Performance Concerns

Query Key Generation (packages/clients/tanstack-query/src/utils/common.ts:179-188):

  • Query keys include full args object, which could be expensive for large/complex objects
  • No memoization of query key generation

Optimistic Updates (packages/clients/tanstack-query/src/utils/mutator.ts:122-147):

  • Array cloning on every mutation could be expensive for large datasets
  • No batching of optimistic updates

Security Concerns

⚠️ Medium Priority Issues:

  1. Data Serialization (packages/clients/tanstack-query/src/utils/serialization.ts:1-39)

    • Using SuperJSON for serialization is generally secure, but custom deserializers need validation
    • Buffer serialization to base64 is safe but consider size limits
  2. Query Parameter Exposure (packages/clients/tanstack-query/src/utils/common.ts:210-221)

    let result = `${url}/${model}/${operation}?q=${encodeURIComponent(JSON.stringify(data))}`;
    • Query parameters might expose sensitive data in logs/URLs
    • Consider POST for complex queries
  3. ID Generation (packages/clients/tanstack-query/src/utils/mutator.ts:216-233)

    insert[f.name] = crypto.randomUUID();
    • Uses crypto.randomUUID() which is good, but ensure it's available in all target environments

Potential Bugs

🐛 Critical Issues:

  1. Race Condition in Optimistic Updates (packages/clients/tanstack-query/src/utils/common.ts:485-490)

    queryClient.setQueryData<unknown>(queryKey, data);
    queryClient.cancelQueries({ queryKey }, { revert: false, silent: true });

    Issue: Query cancellation after cache update could lead to inconsistent state
    Fix: Cancel queries before updating cache

  2. Memory Leak Risk (packages/clients/tanstack-query/src/utils/mutator.ts:235)

    insert.$optimistic = true;

    Issue: $optimistic flags are added but never cleaned up
    Fix: Implement cleanup mechanism for optimistic data

⚠️ Medium Priority Issues:

  1. Infinite Loop Potential (packages/clients/tanstack-query/src/utils/query-analysis.ts:80-98)

    function collectDeleteCascades(model: string, schema: SchemaDef, result: Set<string>, visited: Set<string>) {
        if (visited.has(model)) {
            return; // break circle
        }

    Issue: Recursive cascade detection could still hit edge cases with complex schemas

  2. Error Handling in Visitors (packages/clients/tanstack-query/src/utils/nested-write-visitor.ts:113-133)

    • No error handling in visitor pattern - errors could break entire mutation chain

Performance Considerations

🔧 Optimization Opportunities:

  1. Query Key Memoization: Consider memoizing query key generation for frequently accessed queries
  2. Selective Invalidation: Current invalidation is quite broad - could be more targeted
  3. Optimistic Update Batching: Multiple rapid mutations could cause excessive re-renders
  4. Bundle Size: The package includes many utilities that might not all be needed

Test Coverage

Critical Gap:

No Tests Found: The package has no test files, which is concerning for a library dealing with:

  • Complex state mutations
  • Optimistic updates
  • Cache invalidation logic
  • Type-heavy APIs

Recommendations:

  • Add unit tests for utility functions (especially mutator logic)
  • Add integration tests with TanStack Query
  • Add type-level tests to ensure TypeScript inference works correctly
  • Add performance tests for large dataset scenarios

Minor Issues

  1. Deprecated Export (packages/clients/tanstack-query/src/react.ts:76-80):

    export const Provider = QuerySettingsProvider;

    Good deprecation pattern, but consider adding console warning.

  2. Console Errors (packages/clients/tanstack-query/src/utils/common.ts:155):

    console.error(`Unable to deserialize data:`, textResult);

    Consider using proper logging framework for production.

Next.js Sample Review

The sample application demonstrates good usage patterns:

  • ✅ Proper hook usage and state management
  • ✅ Clean component structure
  • ✅ Good error handling for empty states
  • ⚠️ Missing error boundaries for query failures
  • ⚠️ No loading states shown

Recommendations Summary

  1. High Priority: Add comprehensive test suite
  2. High Priority: Fix type safety issues in hook implementations
  3. Medium Priority: Address race condition in optimistic updates
  4. Medium Priority: Implement cleanup for optimistic data flags
  5. Low Priority: Add performance optimizations for large datasets

This is a solid foundation with good architectural decisions, but needs testing and some critical bug fixes before production use.

5-93: LGTM! Well-structured type definitions.

The type definitions are comprehensive and well-documented. The flexible callback return type (boolean | object | void) provides good control over traversal continuation and payload replacement.


99-106: LGTM!

Constructor and type guard are correctly implemented.


113-133: LGTM! Good normalization of payloads.

The visit method correctly normalizes different payload structures before passing them to doVisit, making the main visitor logic cleaner.


156-168: LGTM! Correct handling of create action.

The reverse enumeration allows callbacks to safely mutate/delete items, and the sub-payload traversal correctly handles nested creates.


170-183: LGTM! Correct extraction of createMany data.

Line 179 correctly extracts data.data based on the createMany argument structure { data: any[], skipDuplicates?: boolean }. The guard at line 143 ensures data is always truthy here.


185-227: LGTM! Correct handling of relation operations.

The implementation correctly handles the various relation operation structures:

  • connectOrCreate: extracts where and create fields
  • connect, disconnect, set: properly handle unique filters and boolean forms

229-280: LGTM! Complex update/upsert logic handled correctly.

The logic properly handles multiple payload structures:

  • update: handles both { where, data } and direct data forms
  • updateMany: extracts where and data appropriately
  • upsert: visits both create and update branches, with callback control over which payloads to traverse

301-303: LGTM! Good defensive error handling.

The default case properly throws an error for unhandled action types, ensuring no silent failures.


307-346: LGTM! Recursive traversal correctly implemented.

The method properly:

  • Handles missing field definitions defensively (line 320)
  • Distinguishes between relation fields (recursing into nested actions) and plain fields (invoking field callback)
  • Preserves the nesting path for context tracking

350-358: LGTM! Smart enumeration strategy.

Reverse-order enumeration allows callbacks to safely mutate or delete the current item without disrupting the iteration. This is a good defensive pattern for visitor implementations.

1-9: LGTM!

The imports and setup are clean. The 'use client' directive is correctly placed, and the lorem-ipsum configuration is appropriate for generating post titles.


10-16: Component setup looks good.

The TanStack Query hooks are used correctly. The posts query properly includes the author relation needed for rendering.


44-46: LGTM!

Good UX pattern—waiting for the fetch to complete before showing the "no users" message with clear guidance.


48-74: LGTM!

Clean layout with responsive design and dark mode support. The "New Post" button styling is complete, and user list rendering is safe with optional chaining.

    Issue: Query cancellation after cache update could lead to inconsistent state
    Fix: Cancel queries before updating cache

  2. Memory Leak Risk (packages/clients/tanstack-query/src/utils/mutator.ts:235)

    insert.$optimistic = true;

    Issue: $optimistic flags are added but never cleaned up
    Fix: Implement cleanup mechanism for optimistic data

⚠️ Medium Priority Issues:

  1. Infinite Loop Potential (packages/clients/tanstack-query/src/utils/query-analysis.ts:80-98)

    function collectDeleteCascades(model: string, schema: SchemaDef, result: Set<string>, visited: Set<string>) {
        if (visited.has(model)) {
            return; // break circle
        }

    Issue: Recursive cascade detection could still hit edge cases with complex schemas

  2. Error Handling in Visitors (packages/clients/tanstack-query/src/utils/nested-write-visitor.ts:113-133)

    • No error handling in visitor pattern - errors could break entire mutation chain

Performance Considerations

🔧 Optimization Opportunities:

  1. Query Key Memoization: Consider memoizing query key generation for frequently accessed queries
  2. Selective Invalidation: Current invalidation is quite broad - could be more targeted
  3. Optimistic Update Batching: Multiple rapid mutations could cause excessive re-renders
  4. Bundle Size: The package includes many utilities that might not all be needed

Test Coverage

Critical Gap:

No Tests Found: The package has no test files, which is concerning for a library dealing with:

  • Complex state mutations
  • Optimistic updates
  • Cache invalidation logic
  • Type-heavy APIs

Recommendations:

  • Add unit tests for utility functions (especially mutator logic)
  • Add integration tests with TanStack Query
  • Add type-level tests to ensure TypeScript inference works correctly
  • Add performance tests for large dataset scenarios

Minor Issues

  1. Deprecated Export (packages/clients/tanstack-query/src/react.ts:76-80):

    export const Provider = QuerySettingsProvider;

    Good deprecation pattern, but consider adding console warning.

  2. Console Errors (packages/clients/tanstack-query/src/utils/common.ts:155):

    console.error(`Unable to deserialize data:`, textResult);

    Consider using proper logging framework for production.

Next.js Sample Review

The sample application demonstrates good usage patterns:

  • ✅ Proper hook usage and state management
  • ✅ Clean component structure
  • ✅ Good error handling for empty states
  • ⚠️ Missing error boundaries for query failures
  • ⚠️ No loading states shown

Recommendations Summary

  1. High Priority: Add comprehensive test suite
  2. High Priority: Fix type safety issues in hook implementations
  3. Medium Priority: Address race condition in optimistic updates
  4. Medium Priority: Implement cleanup for optimistic data flags
  5. Low Priority: Add performance optimizations for large datasets

This is a solid foundation with good architectural decisions, but needs testing and some critical bug fixes before production use.

Code Review Complete

I've completed a comprehensive review of the TanStack Query integration for ZenStack v3. Here's my detailed feedback:

Todo List:

  • Read repository guidelines and setup instructions
  • Analyze core TanStack Query package structure and architecture
  • Review React hooks implementation (packages/clients/tanstack-query/src/react.ts)
  • Examine utility functions and query analysis logic
  • Check mutation handling and nested operations
  • Review Next.js sample application
  • Assess code quality and best practices
  • Identify potential bugs and security issues
  • Evaluate performance considerations
  • Check test coverage
  • Provide comprehensive feedback

Overall Assessment

This is a solid implementation of TanStack Query integration for ZenStack v3. The code demonstrates good TypeScript practices and follows TanStack Query conventions well. However, there are several areas for improvement:

Code Quality & Best Practices

Strengths:

  • Strong TypeScript Integration: Excellent use of generic types and proper typing throughout
  • Clean Architecture: Well-organized separation of concerns with utility modules
  • Proper Hook Patterns: Following React hooks conventions correctly
  • Comprehensive API Coverage: Full CRUD operations including suspense variants and infinite queries
  • Context Pattern: Clean provider pattern for configuration

⚠️ Areas for Improvement:

1. Type Safety Issues (packages/clients/tanstack-query/src/react.ts)

// Lines 219-309: All hook implementations use `any` types
useFindUnique: (args: any, options?: any) => {
    return useInternalQuery(schema, model, 'findUnique', args, options);
},

Issue: The implementation loses all type safety by using any everywhere.
Recommendation: Maintain the generic types through the implementation chain.

2. Error Handling (packages/clients/tanstack-query/src/utils/common.ts:127-158)

if (errData.error?.rejectedByPolicy && errData.error?.rejectReason === 'cannot-read-back') {
    return undefined as any;
}

Issue: Silent failure on policy rejections could mask important errors.
Recommendation: Add optional logging or callback for policy rejections.

3. Performance Concerns

Query Key Generation (packages/clients/tanstack-query/src/utils/common.ts:179-188):

  • Query keys include full args object, which could be expensive for large/complex objects
  • No memoization of query key generation

Optimistic Updates (packages/clients/tanstack-query/src/utils/mutator.ts:122-147):

  • Array cloning on every mutation could be expensive for large datasets
  • No batching of optimistic updates

Security Concerns

⚠️ Medium Priority Issues:

  1. Data Serialization (packages/clients/tanstack-query/src/utils/serialization.ts:1-39)

    • Using SuperJSON for serialization is generally secure, but custom deserializers need validation
    • Buffer serialization to base64 is safe but consider size limits
  2. Query Parameter Exposure (packages/clients/tanstack-query/src/utils/common.ts:210-221)

    let result = `${url}/${model}/${operation}?q=${encodeURIComponent(JSON.stringify(data))}`;
    • Query parameters might expose sensitive data in logs/URLs
    • Consider POST for complex queries
  3. ID Generation (packages/clients/tanstack-query/src/utils/mutator.ts:216-233)

    insert[f.name] = crypto.randomUUID();
    • Uses crypto.randomUUID() which is good, but ensure it's available in all target environments

Potential Bugs

🐛 Critical Issues:

  1. Race Condition in Optimistic Updates (packages/clients/tanstack-query/src/utils/common.ts:485-490)

    queryClient.setQueryData<unknown>(queryKey, data);
    queryClient.cancelQueries({ queryKey }, { revert: false, silent: true });

    Issue: Query cancellation after cache update could lead to inconsistent state
    Fix: Cancel queries before updating cache

  2. Memory Leak Risk (packages/clients/tanstack-query/src/utils/mutator.ts:235)

    insert.$optimistic = true;

    Issue: $optimistic flags are added but never cleaned up
    Fix: Implement cleanup mechanism for optimistic data

⚠️ Medium Priority Issues:

  1. Infinite Loop Potential (packages/clients/tanstack-query/src/utils/query-analysis.ts:80-98)

    function collectDeleteCascades(model: string, schema: SchemaDef, result: Set<string>, visited: Set<string>) {
        if (visited.has(model)) {
            return; // break circle
        }

    Issue: Recursive cascade detection could still hit edge cases with complex schemas

  2. Error Handling in Visitors (packages/clients/tanstack-query/src/utils/nested-write-visitor.ts:113-133)

    • No error handling in visitor pattern - errors could break entire mutation chain

192-198: Wrap marshaled payload under data when meta is present.

We’re still flattening the payload whenever serialization metadata exists, so requests become { ...fields, meta } instead of { data, meta }. That breaks the backend contract (and our own unmarshal) for metadata-bearing operations, leaving them unreadable. Please restore the data wrapper exactly as previously requested.

-        return JSON.stringify({ ...(data as any), meta: { serialization: meta } });
+        return JSON.stringify({ data, meta: { serialization: meta } });

508-525: Pass the QueryCache instance, not the Query array.

The setupOptimisticUpdate function expects a QueryCache instance to call methods like find and getAll, but Line 514 is passing queryClient.getQueryCache().getAll() (which returns a Query[]). This will cause a runtime error when the optimistic update logic attempts to invoke cache methods.

Apply this diff:

             setupOptimisticUpdate(
                 model,
                 operation,
                 schema,
                 finalOptions,
-                queryClient.getQueryCache().getAll(),
+                queryClient.getQueryCache(),
                 (queryKey, data) => {
                     // update query cache
                     queryClient.setQueryData<unknown>(queryKey, data);

Timestamp: 2025-10-21T16:09:31.218Z
Learning: In ZenStack, TypeDefs can be inherited by models. When a TypeDef contains fields with `map` attributes, those mapped field names need to be processed by the QueryNameMapper since they become part of the inheriting model's schema. Therefore, when checking if a schema has mapped names (e.g., in `schemaHasMappedNames`), both `schema.models` and `schema.typeDefs` must be inspected for `@map` and `map` attributes.

228-342: Static analysis false positives: factory pattern is valid.

Biome is flagging numerous useHookAtTopLevel errors for this file, but most are false positives. The pattern here uses factory functions (useClientQueries, useModelQueries) that return objects containing hook implementations. The actual hooks (useInternalQuery, useInternalSuspenseQuery, etc.) properly call React hooks at the top level. Consumers will invoke these returned hooks at the top level of their components, which is the correct pattern for dynamic/configurable hooks.

The only legitimate hook violation is the conditional useContext call at line 496, which is addressed separately.

1-70: Generated code looks consistent.

This is an auto-generated file with consistent type alias patterns for all three models (User, Post, Category). The type definitions appear correct and follow a uniform structure.

Code Review Complete

I've completed a comprehensive review of the TanStack Query integration for ZenStack v3. Here's my detailed feedback:

Todo List:

  • Read repository guidelines and setup instructions
  • Analyze core TanStack Query package structure and architecture
  • Review React hooks implementation (packages/clients/tanstack-query/src/react.ts)
  • Examine utility functions and query analysis logic
  • Check mutation handling and nested operations
  • Review Next.js sample application
  • Assess code quality and best practices
  • Identify potential bugs and security issues
  • Evaluate performance considerations
  • Check test coverage
  • Provide comprehensive feedback

Overall Assessment

This is a solid implementation of TanStack Query integration for ZenStack v3. The code demonstrates good TypeScript practices and follows TanStack Query conventions well. However, there are several areas for improvement:

Code Quality & Best Practices

Strengths:

  • Strong TypeScript Integration: Excellent use of generic types and proper typing throughout
  • Clean Architecture: Well-organized separation of concerns with utility modules
  • Proper Hook Patterns: Following React hooks conventions correctly
  • Comprehensive API Coverage: Full CRUD operations including suspense variants and infinite queries
  • Context Pattern: Clean provider pattern for configuration

⚠️ Areas for Improvement:

1. Type Safety Issues (packages/clients/tanstack-query/src/react.ts)

// Lines 219-309: All hook implementations use `any` types
useFindUnique: (args: any, options?: any) => {
    return useInternalQuery(schema, model, 'findUnique', args, options);
},

Issue: The implementation loses all type safety by using any everywhere.
Recommendation: Maintain the generic types through the implementation chain.

2. Error Handling (packages/clients/tanstack-query/src/utils/common.ts:127-158)

if (errData.error?.rejectedByPolicy && errData.error?.rejectReason === 'cannot-read-back') {
    return undefined as any;
}

Issue: Silent failure on policy rejections could mask important errors.
Recommendation: Add optional logging or callback for policy rejections.

3. Performance Concerns

Query Key Generation (packages/clients/tanstack-query/src/utils/common.ts:179-188):

  • Query keys include full args object, which could be expensive for large/complex objects
  • No memoization of query key generation

Optimistic Updates (packages/clients/tanstack-query/src/utils/mutator.ts:122-147):

  • Array cloning on every mutation could be expensive for large datasets
  • No batching of optimistic updates

Security Concerns

⚠️ Medium Priority Issues:

  1. Data Serialization (packages/clients/tanstack-query/src/utils/serialization.ts:1-39)

    • Using SuperJSON for serialization is generally secure, but custom deserializers need validation
    • Buffer serialization to base64 is safe but consider size limits
  2. Query Parameter Exposure (packages/clients/tanstack-query/src/utils/common.ts:210-221)

    let result = `${url}/${model}/${operation}?q=${encodeURIComponent(JSON.stringify(data))}`;
    • Query parameters might expose sensitive data in logs/URLs
    • Consider POST for complex queries
  3. ID Generation (packages/clients/tanstack-query/src/utils/mutator.ts:216-233)

    insert[f.name] = crypto.randomUUID();
    • Uses crypto.randomUUID() which is good, but ensure it's available in all target environments

Potential Bugs

🐛 Critical Issues:

  1. Race Condition in Optimistic Updates (packages/clients/tanstack-query/src/utils/common.ts:485-490)

    queryClient.setQueryData<unknown>(queryKey, data);
    queryClient.cancelQueries({ queryKey }, { revert: false, silent: true });

    Issue: Query cancellation after cache update could lead to inconsistent state
    Fix: Cancel queries before updating cache

  2. Memory Leak Risk (packages/clients/tanstack-query/src/utils/mutator.ts:235)

    insert.$optimistic = true;

    Issue: $optimistic flags are added but never cleaned up
    Fix: Implement cleanup mechanism for optimistic data

⚠️ Medium Priority Issues:

  1. Infinite Loop Potential (packages/clients/tanstack-query/src/utils/query-analysis.ts:80-98)

    function collectDeleteCascades(model: string, schema: SchemaDef, result: Set<string>, visited: Set<string>) {
        if (visited.has(model)) {
            return; // break circle
        }

    Issue: Recursive cascade detection could still hit edge cases with complex schemas

  2. Error Handling in Visitors (packages/clients/tanstack-query/src/utils/nested-write-visitor.ts:113-133)

    • No error handling in visitor pattern - errors could break entire mutation chain

Performance Considerations

🔧 Optimization Opportunities:

  1. Query Key Memoization: Consider memoizing query key generation for frequently accessed queries
  2. Selective Invalidation: Current invalidation is quite broad - could be more targeted
  3. Optimistic Update Batching: Multiple rapid mutations could cause excessive re-renders
  4. Bundle Size: The package includes many utilities that might not all be needed

Test Coverage

Critical Gap:

No Tests Found: The package has no test files, which is concerning for a library dealing with:

  • Complex state mutations
  • Optimistic updates
  • Cache invalidation logic
  • Type-heavy APIs

Recommendations:

  • Add unit tests for utility functions (especially mutator logic)
  • Add integration tests with TanStack Query
  • Add type-level tests to ensure TypeScript inference works correctly
  • Add performance tests for large dataset scenarios

Minor Issues

  1. Deprecated Export (packages/clients/tanstack-query/src/react.ts:76-80):

    export const Provider = QuerySettingsProvider;

    Good deprecation pattern, but consider adding console warning.

  2. Console Errors (packages/clients/tanstack-query/src/utils/common.ts:155):

    console.error(`Unable to deserialize data:`, textResult);

    Consider using proper logging framework for production.

Next.js Sample Review

The sample application demonstrates good usage patterns:

  • ✅ Proper hook usage and state management
  • ✅ Clean component structure
  • ✅ Good error handling for empty states
  • ⚠️ Missing error boundaries for query failures
  • ⚠️ No loading states shown

Recommendations Summary

  1. High Priority: Add comprehensive test suite
  2. High Priority: Fix type safety issues in hook implementations
  3. Medium Priority: Address race condition in optimistic updates
  4. Medium Priority: Implement cleanup for optimistic data flags
  5. Low Priority: Add performance optimizations for large datasets

This is a solid foundation with good architectural decisions, but needs testing and some critical bug fixes before production use.
