WalkthroughThis change introduces generic typing and a serialization system to the RunCache library, enabling storage and retrieval of any serializable JavaScript value with type safety, instead of just strings. Core types, cache state, middleware, and the RunCache API are updated for generics. Backward compatibility and migration strategies are included. Changes

1-350: Fix ESLint formatting issues in test file.The test coverage is comprehensive and excellent, covering all major scenarios for the typed cache functionality. However, there are multiple formatting issues that need to be addressed:
Apply these fixes for ESLint compliance:
- expect(retrieved).toEqual(user); - + expect(retrieved).toEqual(user); + - const products: Product[] = [ - { id: '1', name: 'Laptop', price: 999.99, category: 'Electronics' }, - { id: '2', name: 'Book', price: 19.99, category: 'Education' }, - ]; + const products: Product[] = [ + { + id: '1', name: 'Laptop', price: 999.99, category: 'Electronics' + }, + { + id: '2', name: 'Book', price: 19.99, category: 'Education' + }, + ]; - const fetchUser = async (): Promise<User> => { - return { - id: 456, - name: 'Jane Doe', - email: 'jane@example.com', - age: 25, - }; - }; + const fetchUser = async (): Promise<User> => ({ + id: 456, + name: 'Jane Doe', + email: 'jane@example.com', + age: 25, + });Also remove trailing spaces throughout the file and add a final newline at the end.
src/run-cache.ts (1)
116-116: Fix formatting issues flagged by ESLint.Please address the following:
- Add blank line after line 116
- Remove trailing spaces from lines 200, 209, 216, 245, 252, 256, 268
- Add parentheses around arrow function parameter on line 259
Apply this fix for line 259:
- return result.map(item => { + return result.map((item) => {Also applies to: 200-200, 209-209, 216-216, 245-245, 252-252, 256-256, 259-259, 268-268

MiddlewareContext<T>properly aligns the method signature with the class's generic type parameter, ensuring type consistency throughout the middleware execution chain.src/types/events.ts (2)
36-53: LGTM: Well-designed generic event parameter type.The addition of generic typing to
EventParamwith proper JSDoc documentation and theserializedValueproperty for compatibility is a solid design choice. This maintains backward compatibility while enabling type-safe event handling.

EventFntype correctly implements the generic pattern with proper JSDoc documentation, maintaining consistency with theEventParam<T>changes.src/types/cache-state.ts (2)
9-22: LGTM: Excellent generic source function implementation.The generic
SourceFn<T>type with comprehensive JSDoc examples clearly demonstrates both synchronous and asynchronous usage patterns. The documentation quality is particularly strong.
28-59: LGTM: Well-structured generic cache state type.The
CacheState<T>implementation is excellent:
- Clear separation between typed
valueandserializedValuefor internal use- Proper generic typing of
sourceFnproperty- Comprehensive JSDoc documentation
- Maintains all existing properties while adding type safety
src/types/middleware.ts (4)
8-26: LGTM: Well-designed generic middleware context.The
MiddlewareContext<T>interface correctly implements generic typing with proper JSDoc documentation. The addition ofserializedValuefor compatibility while maintaining the typedvalueproperty is a good design choice.
32-39: LGTM: Consistent generic middleware function type.The
MiddlewareFunction<T>type properly integrates with the generic context type, maintaining type safety throughout the middleware chain.
43-71: LGTM: Complete generic middleware manager interface.The
MiddlewareManager<T>interface correctly implements all generic method signatures, ensuring type consistency across the middleware management system.
73-80: LGTM: Consistent generic lifecycle middleware types.The lifecycle middleware types (
BeforeMiddleware,AfterMiddleware,ErrorMiddleware) correctly implement generic typing, maintaining consistency with the overall middleware type system.src/core/serialization.ts (3)
10-34: Well-designed serialization adapter interface!The interface provides a clean contract for custom serialization with proper type safety and extensibility.
40-72: Excellent backward compatibility approach!The default adapter correctly preserves string values as-is while supporting JSON serialization for other types. The fallback behavior in deserialization ensures robustness.
78-134: Robust serialization manager implementation!Good design choices:
- LIFO adapter ordering for intuitive override behavior
- Optional type hint for deserialization
- Defensive copy in
getAdapters()prevents external mutationssrc/run-cache.ts (3)
190-222: Excellent backward-compatible generic implementation!The method preserves string behavior while transparently serializing typed values. The sourceFn wrapping ensures consistent serialization throughout the cache lifecycle.
249-276: Robust deserialization with proper error handling!The implementation gracefully handles both single values and arrays from wildcard patterns. The fallback to original strings ensures backward compatibility even if deserialization fails.
619-745: Clean type-safe interface implementation!The
TypedCacheInterfaceprovides an elegant wrapper for typed cache operations. The event callback casting is handled appropriately to maintain compatibility with the underlying event system.game-plan.md (1)
1-490: Comprehensive and well-structured implementation plan!This plan effectively outlines the migration strategy from string-only to generic type-safe caching while maintaining backward compatibility. The phased approach minimizes risk and the examples clearly demonstrate the intended usage patterns.

90-91: SerializationManager instantiated but not used.The
SerializationManageris imported and initialized but its methods (serialize/deserialize) are never called within this file. Is this intentional for a future phase of implementation, or should the serialization be integrated into the cache operations?Also applies to: 110-110
16-25: Consistent generic type annotations throughout!The explicit
<string>typing forCacheStateand<string | undefined>for middleware contexts maintains type safety and clarity. The distinction appropriately reflects that cache operations may return undefined.Also applies to: 72-72, 84-84, 314-314, 549-549, 578-578, 708-708, 1111-1111, 1136-1136, 1161-1161, 1258-1258, 1267-1267

🧹 Nitpick comments (6)
src/utils/migration.ts (3)
4-145: Consider refactoring to module functions instead of a static-only class.Static analysis correctly identifies that this class contains only static members. Consider refactoring to exported functions for better tree-shaking and clearer intent.
Instead of a class with static methods, consider:
-export class CacheMigrationUtils { - static migrateStringCacheToTyped<T>( +export function migrateStringCacheToTyped<T>( existingData: string, typeConstructor?: new (...args: any[]) => T, ): T { // First, try to detect if this is already a serialized object - const valueType = this.detectValueType(existingData); + const valueType = detectValueType(existingData); // ... rest of the implementation } -} +export function detectValueType(serialized: string): 'string' | 'object' | 'array' | 'primitive' { + // ... implementation +} + +// ... other exported functionsThis would eliminate the static context issues and provide a cleaner API.
16-16: Replacethiswith class name in static context.For better clarity, use the class name instead of
thisin static methods.-const valueType = this.detectValueType(existingData); +const valueType = CacheMigrationUtils.detectValueType(existingData);-if (this.isNumericString(existingData)) { +if (CacheMigrationUtils.isNumericString(existingData)) {-if (this.isNumericString(serialized) - || this.isBooleanString(serialized) +if (CacheMigrationUtils.isNumericString(serialized) + || CacheMigrationUtils.isBooleanString(serialized)Also applies to: 39-39, 63-64
49-53: Remove redundant case clause.The
'string'case has the same implementation asdefault, making it redundant.-case 'string': default: // If it's a plain string, return as-is return existingData as unknown as T;src/core/type-validation.test.ts (1)
472-482: Consider making the performance test more robust.The hard-coded 100ms threshold could cause flaky tests on slower CI environments or under heavy load.
Consider using a more flexible approach:
-// Validation should complete within reasonable time (< 100ms) -expect(end - start).toBeLessThan(100); +// Validation should complete within reasonable time +// Use a higher threshold for CI environments +const maxDuration = process.env.CI ? 500 : 100; +expect(end - start).toBeLessThan(maxDuration);Alternatively, consider focusing on algorithmic complexity by comparing relative performance rather than absolute time.
src/core/type-validation.ts (1)
208-272: Consider using standalone functions instead of a static-only class.While the current implementation works well, the
ValidatorUtilsclass contains only static methods, which could be refactored into standalone functions for better tree-shaking and simpler imports.-export class ValidatorUtils { - /** - * Creates a validator for a literal value - */ - static literal<T extends string | number | boolean>(literalValue: T): TypeValidator<T> { +/** + * Creates a validator for a literal value + */ +export function literal<T extends string | number | boolean>(literalValue: T): TypeValidator<T> { return new SchemaValidator( (value): value is T => value === literalValue, `"${literalValue}"`, ); - } +} - /** - * Creates a validator for string enums - */ - static stringEnum<T extends string>(...values: T[]): TypeValidator<T> { +/** + * Creates a validator for string enums + */ +export function stringEnum<T extends string>(...values: T[]): TypeValidator<T> { return new SchemaValidator( (value): value is T => typeof value === 'string' && values.includes(value as T), `"${values.join('" | "')}"`, ); - } +}This would allow for more flexible imports:

This ensures proper backward compatibility with existing string-only cache data.
src/types/cache-config.ts (1)
52-97: Well-designed type-safe configuration interface!The
TypedCacheConfig<T>interface provides excellent flexibility for configuring type validation and serialization behavior. The JSDoc comments clearly explain each property and their defaults, making it easy for users to understand and configure typed caches.src/utils/migration.test.ts (1)

170-176: Simplify the arrow function to improve readability.Apply this diff to use a more concise arrow function style:
- const mockApiCall = async (): Promise<ApiResponse> => { - // Simulate API call - return { - data: ['item1', 'item2', 'item3'], - timestamp: Date.now() - }; - }; + const mockApiCall = async (): Promise<ApiResponse> => ({ + // Simulate API call + data: ['item1', 'item2', 'item3'], + timestamp: Date.now(), + });
553-553: Add newline at end of file.Add a newline character at the end of the file to comply with ESLint rules.
src/examples/serialization-adapters.test.ts (1)
365-406: Consider adding a test for adapter priority in CompositeSerializationAdapter.The composite adapter adds adapters to the front of the array for priority. It would be good to test this behavior explicitly.
Add a test case to verify adapter priority:
it('should respect adapter priority order', () => { const composite = new CompositeSerializationAdapter(); // Create two adapters that can handle the same type const adapter1 = { serialize: (value: string) => `adapter1:${value}`, deserialize: (serialized: string) => serialized.replace('adapter1:', ''), canHandle: (value: any) => typeof value === 'string' && value.startsWith('test') }; const adapter2 = { serialize: (value: string) => `adapter2:${value}`, deserialize: (serialized: string) => serialized.replace('adapter2:', ''), canHandle: (value: any) => typeof value === 'string' && value.startsWith('test') }; // Add adapter2 first, then adapter1 composite.addAdapter(adapter2); composite.addAdapter(adapter1); // adapter1 should be used since it was added last (higher priority) const result = composite.serialize('test value'); expect(result).toBe('adapter1:test value'); });src/examples/serialization-adapters.ts (2)
347-393: Consider refactoring the deserialize method for better maintainability.The current implementation has hard-coded type checks for each adapter type, making it difficult to maintain when adding new adapters. Consider letting each adapter handle its own type detection.
Instead of hard-coding type checks, consider this approach:
deserialize(serialized: string): any { // Try to parse and check for __type__ marker try { const parsed = JSON.parse(serialized); if (parsed && typeof parsed === 'object' && parsed.__type__) { // Let each adapter try to deserialize for (const adapter of this.adapters) { try { const result = adapter.deserialize(serialized); // Verify the adapter actually handled it if (result !== undefined && adapter.canHandle(result)) { return result; } } catch { // Continue to next adapter } } // No adapter handled it, return parsed object return parsed; } } catch { // Not valid JSON } // Default handling try { return JSON.parse(serialized); } catch { return serialized; } }This approach:
- Removes tight coupling to specific types
- Makes it easier to add new adapters without modifying the composite adapter
- Lets each adapter decide if it can handle the deserialization
20-30: Consider adding optional error logging for debugging.The adapters silently catch and handle errors, which could make debugging difficult in production.
Consider adding an optional logger or debug mode:
export interface SerializationAdapterOptions { debug?: boolean; logger?: (message: string, error?: any) => void; } export class DateSerializationAdapter implements SerializationAdapter<Date> { constructor(private options: SerializationAdapterOptions = {}) {} deserialize(serialized: string): Date { try { const parsed = JSON.parse(serialized); if (parsed.__type__ === 'Date') { return new Date(parsed.value); } } catch (error) { // Fallback to direct parsing if (this.options.debug) { const logger = this.options.logger || console.warn; logger('Failed to deserialize as typed Date, falling back to direct parsing', error); } } return new Date(serialized); } }Also applies to: 48-58, 76-86

10-553: Excellent comprehensive test coverage!The test suite effectively demonstrates:
- Backward compatibility with string-only operations
- Type-safe caching with interfaces and generics
- Complex nested objects and collections
- Custom serialization adapters
- Type validation integration
- Edge cases and mixed usage scenarios
The examples serve as both tests and documentation for the new typed cache functionality.
22-553: Ignore formatting suggestions for trailing whitespace and missing trailing commasBased on our project conventions for the run-cache repo, we don’t enforce trailing-whitespace or missing-trailing-comma rules in test files—please disregard those formatting concerns.
Likely an incorrect or invalid review comment.

19-475: Excellent test coverage for serialization adapters!The test suite is comprehensive and well-structured:
- All adapter types are thoroughly tested
- Edge cases and error conditions are covered
- Type preservation and instanceof checks are verified
- Environment-specific tests (Buffer) are properly handled
- The tests serve as good documentation for adapter usage
src/examples/serialization-adapters.ts (1)
285-324: Well-implemented TypedArraySerializationAdapter!The adapter correctly handles:
- Buffer slicing for array views (handling byteOffset and byteLength)
- Conversion to/from byte arrays for serialization
- Generic support for all typed array types
game-plan.md (1)
1-529: Excellent implementation plan for dynamic types!The document provides:
- Clear phased approach maintaining backward compatibility
- Comprehensive code examples for each feature
- Well-defined testing and migration strategies
- Risk mitigation considerations
- Realistic timeline
This plan effectively guides the transformation of RunCache from string-only to a fully generic, type-safe cache.

src/comprehensive-integration.test.ts (1)
30-45: Clarify the circular reference handling test.The test accepts both successful storage and errors as valid outcomes, but the comment about "fall back to string storage" isn't reflected in the implementation.
Consider being more specific about the expected behavior:
-// This should not crash the cache, but may fall back to string storage +// Circular references aren't serializable with standard JSON.stringify() +// The cache should either: +// 1. Throw an error (which we catch) +// 2. Use a custom serializer that handles circular refs +// 3. Store undefinedgitbook/getting-started/typed-caching.md (1)

659-661:JSON.stringifyas cache key is fragileUsing
JSON.stringifydirectly:
- Throws on circular references.
- Produces very large keys for big objects.
- Leaks PII into the key space.

11-11: Plural agreement nit-- `T` - The type of values that will be cached in this interface +- `T` – The type of value(s) cached by this interfacegame-plan.md (4)
141-157: Simplify the extra type parameter onCacheStore.set
set<K extends T>introduces a second generic that rarely brings additional benefit and makes inference harder (especially whenTis a union). The store is already parameterised byT, so acceptingvalue?: Tis usually sufficient and clearer.- // New generic set method - async set<K extends T>({ + // New generic set method + async set({ key, value, ttl, @@ - }: { + }: { key: string; - value?: K; + value?: T; @@ - sourceFn?: SourceFn<K>; + sourceFn?: SourceFn<T>;
162-165: Clarify the return contract ofCacheStore.get
get<K extends T = T>(key): Promise<K | K[] | undefined>mixes singular and collection return types, forcing the caller to discriminate at runtime. Consider separating concerns:
get<T>(key): Promise<T | undefined>getMany<T>(pattern): Promise<T[]>This keeps each method’s return type unambiguous.
347-347: Hyphenate compound adjective“Backward-compatible string operations” needs a hyphen.
- - Backward compatible string operations + - Backward-compatible string operations
599-606: Plan for concurrency & thread safetyThe roadmap omits risks around concurrent access (multi-worker Node, clustered environments, browser tabs). Serialisation managers and adapter registries should be:
- either immutable after initialisation, or
- protected with synchronisation (e.g.,
Atomics, mutex per process, or message passing).Add a bullet under “Risk Mitigation” to address data races and stale adapter lists.

🔇 Additional comments (10)
gitbook/SUMMARY.md (1)
8-8: Documentation structure looks well-organized.The new documentation entries for typed caching features are properly categorized across the appropriate sections. This provides a logical flow for users learning about and migrating to the new typed caching system.
Also applies to: 25-26, 33-34, 40-40
gitbook/api/run-cache.md (4)
52-136: Excellent documentation of the genericset<T>()method.The documentation clearly explains the new generic typing capabilities while maintaining backward compatibility through the default
T = stringparameter. The progression of examples from simple strings to complex typed objects with validation provides a comprehensive guide for users at different adoption stages.
138-199: Clear documentation of the genericget<T>()method.The return type
Promise<T | T[] | undefined>correctly captures the three possible outcomes: typed value for specific keys, array of typed values for pattern matching, or undefined if not found. The examples effectively demonstrate TypeScript's type inference benefits.
657-703: Well-documentedcreateTypedCache<T>()method.This new method provides an elegant way to create type-safe cache instances for specific domain types. The examples effectively demonstrate how TypeScript enforces type correctness at compile time, preventing type mismatches.
715-715: Good catch on the typo fix.Correcting "typitten" to "typescript" ensures proper syntax highlighting in the code block.
gitbook/guides/migration-guide.md (1)
1-480: Comprehensive and well-structured migration guide.This migration guide excellently covers all aspects of transitioning from string-only to typed caching:
- Clear phased approach maintaining backward compatibility
- Practical before/after code examples
- Helpful migration utilities and batch conversion strategies
- Realistic timeline recommendations
- Important coverage of edge cases and pitfalls
The guide will significantly ease the adoption of the new typed caching features.
src/performance.test.ts (2)
46-402: Well-structured performance test suite.The performance tests effectively cover:
- Serialization overhead for different data types and sizes
- Memory usage patterns and efficiency
- Custom serialization adapter performance
- Batch operation scalability
The progressive test sizes and reasonable time thresholds help identify performance regressions. The console.log statements aid in performance debugging.
1-402: Fix the numerous ESLint style violations.The file has many style issues that should be addressed:
- Remove trailing spaces throughout the file
- Add missing trailing commas
- Add newline at end of file
Run the following to auto-fix most issues:
npx eslint src/performance.test.ts --fixFor the arrow function style issues that can't be auto-fixed, you can keep the current block style as it improves readability for complex object generation.

68-96: Good concurrent operations test.This test effectively validates that the cache handles parallel operations correctly without data loss or corruption. The use of 100 concurrent operations provides a reasonable stress test.
1-466: Fix ESLint violations and maintain the excellent test coverage.Like the performance test file, this has numerous style issues that should be fixed with
eslint --fix.The integration test coverage is excellent, particularly:
- Edge case handling for null/undefined/circular references
- Complex TypeScript type scenarios
- Integration with existing features (TTL, tags, events)

228-229: Fix the flaky memory test that's causing pipeline failures.This test is failing because garbage collection timing is non-deterministic. The expectation that
memoryAfterFlush < memoryIncrease * 5is too strict even with the acknowledged leniency.Consider these alternatives:
-// Memory should be mostly cleaned up after flush (very lenient check due to GC timing) -expect(memoryAfterFlush).toBeLessThan(memoryIncrease * 5); +// Option 1: Remove the flaky assertion +// Memory cleanup verification is unreliable due to GC timing +// Option 2: Make it even more lenient +// expect(memoryAfterFlush).toBeLessThan(memoryIncrease * 10); +// Option 3: Only verify that flush was called without checking memory +expect(memoryIncrease).toBeGreaterThan(0); +console.log('Memory was freed but GC timing is non-deterministic');gitbook/advanced/type-validation.md (1)
408-426: Duplicate identifiertransformstill breaks compilation
A private field and a method share the same name. TypeScript forbids this.-class TransformingValidator<TInput, TOutput> implements TypeValidator<TOutput> { - constructor( - public name: string, - private transform: (input: TInput) => TOutput | null, - private baseValidator: TypeValidator<TInput> - ) {} +class TransformingValidator<TInput, TOutput> implements TypeValidator<TOutput> { + constructor( + public name: string, + private transformFn: (input: TInput) => TOutput | null, + private baseValidator: TypeValidator<TInput> + ) {} … - const transformed = this.transform(value); + const transformed = this.transformFn(value); … - transform(value: TInput): TOutput | null { - return this.transform(value); + apply(value: TInput): TOutput | null { + return this.transformFn(value); } }game-plan.md (1)
254-266: Legacy JSON detection heuristic is still lossyJSON strings that lack
__type__metadata (e.g."{"foo":"bar"}") are still classified as legacy, so they are returned unparsed and silently drop typed payloads saved before adapters were added. Consider:
- Attempting
JSON.parse; treat successfully-parsed objects as modern values, or- Always embedding metadata on serialization.
This mirrors earlier feedback.

203-206: Add the missing comma for readability
RunCache supports complex TypeScript types including unions and enumsInsert a comma after “types” so the sentence reads naturally.

210-218: Clarify generic return type to preserve TypedArray information
RunCache.get('audio:sample')returnsanyin the example, losing compile-time safety.
Explicitly parameterising the call keeps TS aware of the expected typed array.-const retrievedAudio = await RunCache.get('audio:sample'); +const retrievedAudio = await RunCache.get<Float32Array>('audio:sample');Same applies to the

21-23: Add missing article for clarity“Reconstructs a value from serialized string” is missing the article “a.”
Recommend updating to “Reconstructs a value from a serialized string” for grammatical correctness.
477-488:TypedArrayis not a global TypeScript type
TypedArrayis a convenience name used in MDN docs but isn’t defined in the DOM lib.
Consider replacing it withArrayBufferViewor the union of concrete typed-array types to avoid confusion for consumers copying this code verbatim.-class TypedArraySerializationAdapter<T extends TypedArray> +class TypedArraySerializationAdapter< + T extends + | Int8Array | Uint8Array + | Int16Array | Uint16Array + | Int32Array | Uint32Array + | Float32Array | Float64Array +>

gitbook/SUMMARY.md (1)
8-8: Documentation structure looks well-organized for the new typed features.The additions properly categorize the new typed caching capabilities across Getting Started, Advanced Features, API Reference, and Guides sections. This provides a logical progression for users learning about the typed features.
Also applies to: 25-26, 33-34, 40-40
gitbook/api/run-cache.md (3)
52-74: Excellent documentation of the genericsetmethod.The type parameter documentation and examples clearly show how to use the new typed functionality while maintaining backward compatibility. The progression from basic string usage to complex typed scenarios is very helpful.
138-199: Comprehensive typedgetmethod documentation.The examples demonstrate various retrieval patterns including single values, arrays, pattern matching, and complex generic types. This provides excellent guidance for developers transitioning to typed caching.
657-704: Well-documentedcreateTypedCache<T>()method.The new method provides a clean way to create strongly typed cache interfaces. The examples with separate
UserandProductcaches clearly demonstrate the type safety benefits and how TypeScript will enforce correct usage.gitbook/guides/migration-guide.md (3)
9-26: Excellent migration strategy overview.The phased approach starting with "No Changes Required" provides confidence to users that their existing code will continue to work. This non-breaking migration strategy is well thought out.
74-238: Comprehensive migration pattern examples.The before/after examples for simple objects, API responses, source functions, and collections provide clear guidance for common use cases. Each example shows the practical benefits of the new typed approach.
390-452: Valuable coverage of common pitfalls.The sections on circular references, Date objects, and function properties address real-world serialization challenges that developers will encounter. The solutions and workarounds are practical.
src/performance.test.ts (2)
1-45: Comprehensive performance test setup with good data generators.The test data generators for large objects, string data, and complex typed data provide realistic scenarios for performance testing. The complex data including Date, Map, Set, and other types covers the serialization system well.
52-181: Thorough serialization performance benchmarks.The tests properly measure performance across different data sizes and types, with reasonable thresholds for operation times. The comparison between string and typed operations provides valuable insight into serialization overhead.
src/comprehensive-integration.test.ts (4)
13-128: Excellent edge case and error handling coverage.The tests cover important scenarios like null/undefined values, circular references, large objects, concurrent operations, and type coercion. These edge cases are crucial for validating the robustness of the typed caching system.
130-244: Comprehensive TypeScript scenario testing.The complex nested interfaces, generic types, arrays, and union types demonstrate that the typed caching system handles sophisticated TypeScript patterns correctly. This builds confidence in the type safety implementation.
246-396: Thorough integration testing with existing features.The integration tests with TTL, source functions, tags, dependencies, and events verify that the new typed features work seamlessly with all existing RunCache functionality. This is critical for maintaining feature compatibility.
398-465: Valuable backward compatibility verification.The tests confirming that legacy string-only usage continues to work alongside new typed usage are essential for validating the non-breaking nature of this enhancement.

246-249: Excellent improvement to address flaky memory test.The much more lenient memory check (15x multiplier with 150MB buffer) properly addresses the non-deterministic garbage collection issue mentioned in the past review comments. This should eliminate the CI failures.
🧹 Nitpick comments (6)
src/performance.test.ts (6)
28-30: Clean up arrow function style for consistency.The ESLint rule suggests simplifying the arrow function by removing unnecessary block statements.
Apply this diff to improve consistency:
-const generateStringData = (size: number) => { - return Array.from({ length: size }, (_, i) => `string-value-${i}`); -}; +const generateStringData = (size: number) => + Array.from({ length: size }, (_, i) => `string-value-${i}`);
32-44: Simplify arrow function and fix Buffer type safety.The function has unnecessary block statements and potential type safety issues with Buffer.
Apply this diff to improve the code:
-const generateComplexTypedData = (size: number) => { - return Array.from({ length: size }, (_, i) => ({ +const generateComplexTypedData = (size: number) => + Array.from({ length: size }, (_, i) => ({ id: i, date: new Date(), map: new Map<string, any>([['key1', 'value1'], ['key2', i]]), set: new Set([1, 2, 3, i]), regex: new RegExp(`pattern${i}`, 'g'), // Remove BigInt to avoid serialization issues in performance tests largeNumber: i * 1000000, url: new URL(`https://example.com/user/${i}`), - buffer: typeof Buffer !== 'undefined' ? Buffer.from(`data${i}`) : null, - })); -}; + buffer: typeof Buffer !== 'undefined' ? Buffer.from(`data${i}`) : undefined, + }));
192-192: Fix Promise executor return value issues.The ESLint rule correctly identifies that return values from Promise executor functions cannot be read.
Apply this diff to fix the Promise usage:
- await new Promise(resolve => setTimeout(resolve, 100)); + await new Promise((resolve) => { setTimeout(resolve, 100); });- await new Promise(resolve => setTimeout(resolve, 1000)); + await new Promise((resolve) => { setTimeout(resolve, 1000); });Also applies to: 228-228
388-388: Fix variable shadowing in batch operations.The
_parameter in the inner map function shadows the outer scope variable.Apply this diff to fix the shadowing:
- data: Array.from({ length: 5 }, (_, j) => `data${j}`), + data: Array.from({ length: 5 }, (__, j) => `data${j}`),
394-396: Improve code formatting for readability.The Promise.all call has inconsistent formatting that affects readability.
Apply this diff to improve formatting:
- const setPromises = testData.map(({ key, value }) => - RunCache.set({ key, value }) - ); + const setPromises = testData.map(({ key, value }) => + RunCache.set({ key, value }), + );
1-422: Address ESLint formatting issues consistently.The file has numerous trailing spaces and missing trailing commas that should be fixed for consistency with the project's linting rules.
Consider running the following command to auto-fix most formatting issues:
#!/bin/bash # Auto-fix ESLint issues npm run lint -- --fix src/performance.test.ts

src/performance.test.ts (2)
142-180: Performance overhead comparison is well-designed.The test properly compares string vs typed operations and ensures serialization overhead stays under 200%. The implementation correctly flushes cache between tests to avoid interference.
77-77: Configure and validate performance thresholdsThe performance tests are currently failing due to a missing
ts-jestpreset, so the 2ms/5ms/10ms thresholds can’t be validated yet. Please:
- Add and configure the
ts-jestpreset in your Jest configuration (e.g. setpreset: "ts-jest"injest.config.js) and installts-jestas a dev dependency.- Re-run the performance tests multiple times (e.g.
npm test -- --testNamePattern="Performance Tests") on your CI environment to confirm the thresholds are realistic, especially on slower systems.Applies to
src/performance.test.tsat lines 77, 107, and 136.
