5-6: Consider optimizing the memoization implementation

While using React.memo is a good practice for performance optimization, the current implementation could be improved. The onClick handler and className composition are recreated on every render, potentially negating the benefits of memoization.

Consider this optimization:

+const handleReload = () => {
+  window.location.reload();
+};

-export const RefreshButton = React.memo(
-  ({ className }: { className?: string }) => {
+export const RefreshButton = React.memo(({ className }: { className?: string }) => {
+  const buttonClassName = clsx(
+    `transition font-extrabold bg-orange-700 text-lg text-white`,
+    className,
+  );

    return (
      <Button
-       onClick={() => {
-         window.location.reload();
-       }}
-       className={clsx(
-         `transition font-extrabold bg-orange-700 text-lg text-white`,
-         className,
-       )}
+       onClick={handleReload}
+       className={buttonClassName}
        name="Reload page"
      >
        Reload page
      </Button>
    );
-  },
);

8-19: Consider enhancing user experience and accessibility

The button implementation could benefit from additional UX considerations:

  1. Add a confirmation dialog before reloading to prevent accidental clicks
  2. Provide visual feedback during the reload process
  3. Enhance accessibility with additional ARIA attributes

Consider this enhancement:

 <Button
-  onClick={() => {
-    window.location.reload();
-  }}
+  onClick={() => {
+    if (window.confirm('Are you sure you want to reload the page?')) {
+      window.location.reload();
+    }
+  }}
   className={clsx(
     `transition font-extrabold bg-orange-700 text-lg text-white`,
     className,
   )}
   name="Reload page"
+  aria-label="Reload page"
+  role="button"
 >
   Reload page
 </Button>
vitest.config.ts (2)

8-8: Consider expanding test file patterns

The current pattern might miss some test files. Consider adding support for .spec files which are commonly used in the ecosystem.

-    include: ["**/*.test.?(c|m)[jt]s?(x)"],
+    include: ["**/*.{test,spec}.?(c|m)[jt]s?(x)"],

18-21: Consider enhancing type checking configuration

While the current setup with dts: true is good, consider adding explicit type checking options for better IDE support.

    AutoImport({
      imports: ["vitest"],
      dts: true, // generate TypeScript declaration
+     // Add type checking options
+     typeCheck: true,
+     dtsDir: './types',
    }),
packages/urlstate/parseSPObj.test.ts (1)

Line range hint 23-35: Consider adding more error test cases.

While the migration to Vitest is correct, consider adding more error test cases to improve coverage:

  • Test with malformed JSON structures
  • Test with unexpected data types
  • Test with missing required fields

Would you like me to help generate additional test cases?

packages/urlstate/subscribers.ts (2)

30-31: Consider improving type safety of the get method

The current implementation uses type casting which could mask potential type errors. Consider a more type-safe approach.

Here's a suggested improvement:

-  get: function <T extends JSONCompatible | undefined>(objKey: T): T | undefined {
-    return _stateMap.get(objKey as JSONCompatible) as T;
+  get: function <T extends JSONCompatible>(objKey: T): T | undefined {
+    return _stateMap.get(objKey) as T | undefined;

This change:

  1. Narrows the input type to just JSONCompatible
  2. Makes the undefined return type explicit
  3. Reduces unnecessary type casting

Line range hint 6-8: Consider documenting the subscription lifecycle management

The TODO comment raises valid concerns about clarity. While keeping React 17 compatibility is important, consider:

  1. Adding documentation about the subscription lifecycle
  2. Implementing safeguards against potential memory leaks
  3. Creating a migration plan for future React 18+ support

Would you like me to help create:

  1. Documentation explaining the current subscription model
  2. A proof-of-concept using useSyncExternalStore for future reference
packages/example-nextjs14/src/app/layout.tsx (2)

Line range hint 24-31: Review HTML structure and meta tags placement.

The current structure mixes <link>, <meta>, and <script> tags in a non-standard order. Consider reorganizing the head section for better maintainability:

    <html lang="en">
+     <head>
+       <meta name="google-site-verification" content="NKunqTB4Sd_Bp6zoIbzKvw_WoGB-v2-MXxC5mbKJKJw" />
+       {isVercel && <link rel="canonical" href={vercelUrl}></link>}
        <link rel="preconnect" href="https://fonts.googleapis.com" />
        <link rel="preconnect" href="https://fonts.gstatic.com" crossOrigin="" />
-       {/* {!isProd && <script src="https://unpkg.com/react-scan/dist/auto.global.js" async /> } */}
-       {isVercel && <link rel="canonical" href={vercelUrl}></link>}
-       <meta name="google-site-verification" content="NKunqTB4Sd_Bp6zoIbzKvw_WoGB-v2-MXxC5mbKJKJw" />
+     </head>
      <body className={`${roboto.className}`}>

Line range hint 30-31: Consider combining analytics conditions.

The separate conditional renders for Google Analytics and Vercel Analytics could be combined for better readability:

-      {isProd ? <GoogleAnalytics gaId="G-5N8Y565DXK" /> : null }
-      {isProd && isVercel ? <Analytics /> : null}
+      {isProd && (
+        <>
+          <GoogleAnalytics gaId="G-5N8Y565DXK" />
+          {isVercel && <Analytics />}
+        </>
+      )}
packages/example-nextjs14/src/app/Status.tsx (1)

Line range hint 8-52: Consider adding error handling and prop validation

A few suggestions to improve robustness:

  1. Add prop validation for the urlState object to handle potential undefined values
  2. Consider wrapping the JSON.stringify calls in try-catch blocks
  3. The pre element has a hardcoded height which might cause content truncation

Here's a suggested implementation:

 export const Status = React.memo(({
   className,
   sp,
   ghLink
 }: {
   className?: string;
   sp?: object;
   ghLink: string;
 }) => {
   const { urlState } = useUrlState(form, {
     searchParams: sp,
     replace: false,
   });
+
+  const safeStringify = (value: unknown) => {
+    try {
+      return JSON.stringify(value);
+    } catch (error) {
+      console.error('Failed to stringify value:', error);
+      return '""';
+    }
+  };
+
+  if (!urlState) {
+    return <div>Loading...</div>;
+  }

   return (
     <div className={`flex relative shadow-md hover:shadow-lg ${className} `}>
       <div className="font-semibold mb-2 ">
         Other client component
       </div>
       <h3>Types and structure of data are presered</h3>

       <div className="flex-none">
         <pre
           className="max-h-[330px] text-sm overflow-y-auto
          text-gray-600 bg-white p-4 rounded-md shadow-inner
           break-all whitespace-pre-wrap"
           data-testid="parsed"
         >
           <div>{'{'}</div>
             <div className="ml-4">
-              <div><b>name:</b> {urlState.name}</div>
-              <div><b>age:</b> {urlState.age}</div>
-              <div><b>agree:</b> {JSON.stringify(urlState.agree_to_terms)}</div>
-              <div><b>tags:</b> {JSON.stringify(urlState.tags, null, 2)}</div>
+              <div><b>name:</b> {urlState.name ?? ''}</div>
+              <div><b>age:</b> {urlState.age ?? ''}</div>
+              <div><b>agree:</b> {safeStringify(urlState.agree_to_terms)}</div>
+              <div><b>tags:</b> {safeStringify(urlState.tags)}</div>
             </div>
           <div>{'}'}</div>
         </pre>
       </div>
packages/urlstate/useSharedState/useSharedState.ts (1)

55-58: Consider enhancing type safety in setState implementation

The current implementation is functionally correct, but there's room for improvement in type safety:

Consider this alternative implementation for better type inference and runtime safety:

-      const newVal = isFunc ? value(curr as T) : { ...curr, ...value };
-      if (isEqual(curr, newVal)) return void 0;
-      stateMap.set(stateShape.current, newVal);
-      subscribers.get(stateShape.current).forEach((sub) => sub());
+      const currentState = curr as T;
+      if (!currentState) {
+        console.warn('State unexpectedly undefined');
+        return;
+      }
+      const newVal = isFunc 
+        ? value(currentState) 
+        : { ...currentState, ...value };
+      if (isEqual(currentState, newVal)) return;
+      stateMap.set(stateShape.current, newVal);
+      subscribers.get(stateShape.current).forEach((sub) => sub());

This refactor:

  1. Moves type assertion earlier for better type inference
  2. Adds runtime validation for unexpected undefined state
  3. Improves readability by breaking down the ternary operation
  4. Removes redundant void 0
packages/urlstate/encoder/encoder.ts (1)

34-34: Consider adding tests for deeply nested structures.

The recursive handling of nested objects and arrays looks correct, but it would be beneficial to add test cases that verify:

  1. Deep object nesting (>5 levels)
  2. Mixed array/object structures
  3. Edge cases with empty objects/arrays

Would you like me to help generate comprehensive test cases for these scenarios?

Also applies to: 40-40

packages/urlstate/utils.test.ts (1)

Line range hint 133-190: LGTM with suggestions for additional test cases

The test coverage for filterUnknown and filterUnknownParamsClient is comprehensive and well-structured. Consider adding these edge cases:

  1. For filterUnknownParamsClient:
    • URL with malformed parameters
    • Unicode characters in parameters
  2. For filterUnknown:
    • Nested shape objects
    • Array values in entries

Also applies to: 195-234

packages/urlstate/useSharedState/useSharedState.test.ts (2)

9-10: LGTM! Consider consolidating mock setup.

The migration to Vitest mocking is implemented correctly. However, since both mocks use the same options, consider consolidating them:

-vi.mock('../utils', { spy: true });
-vi.mock('../subscribers', { spy: true })
+const mockModules = ['../utils', '../subscribers'] as const;
+mockModules.forEach(module => vi.mock(module, { spy: true }));

29-29: Enhance test descriptions for better clarity.

While the test implementation is solid, some test descriptions could be more descriptive. Consider using the "it should" pattern to make the test's purpose clearer:

-test('always use getInitial', () => {
+test('should always use getInitial value when running on server', () => {

-test('when value empty return value from _getInitial', () => {
+test('should return value from getInitial when stateMap is empty', () => {

-test('should get value from stateMap without getInitial', () => {
+test('should retrieve existing value from stateMap without calling getInitial', () => {

-test('should set value if not in stateMap', () => {
+test('should initialize stateMap with default value when empty', () => {

-test('should return state', () => {
+test('should return current state through both state and getState()', () => {

-test('should set stateMap and subscribers', async () => {
+test('should properly initialize stateMap and setup subscribers', async () => {

Also applies to: 42-42, 57-57, 77-77, 100-100, 108-108

packages/urlstate/encoder/encoder.test.ts (4)

24-24: Consider using structuredClone instead of spread operator

The spread operator performs a shallow clone, which might not be sufficient for nested objects. For consistency with other tests in this file and to ensure deep cloning, consider using structuredClone.

-const obj = { ...obj1 }
+const obj = structuredClone(obj1)

Line range hint 267-273: Remove console.log and consider proper benchmarking

Console.log statements should be removed from test files. For performance testing, consider using Vitest's built-in benchmarking capabilities or a dedicated benchmarking library.

  test('encode/decode', () => {
-   const a1 = performance.now();
    const result = decode(encode(bigObj));
-   const a2 = performance.now();
-   console.log('encode time', a2 - a1 + ' milliseconds');
    expect(result).toStrictEqual(bigObj);
  });

277-277: Fix typo in test description

The test description contains a typo: "specia" should be "special".

-  test('should encode with specia symbols', () => {
+  test('should encode with special symbols', () => {

Line range hint 286-294: Consider organizing primitive type tests into separate test cases

The current test combines multiple unrelated primitive types into a single test. Consider splitting these into separate, focused test cases for better readability and maintenance.

describe('primitive type handling', () => {
  test('should handle null and undefined', () => {
    expect(decodePrimitive(null as unknown as string)).toStrictEqual(null);
  });

  test('should handle boolean values', () => {
    expect(decodePrimitive(false as unknown as string)).toStrictEqual(false);
    expect(decodePrimitive(true as unknown as string)).toStrictEqual(true);
  });

  // ... similar groupings for numbers, arrays, objects, strings
});
package.json (1)

354-354: Review coverage reporting strategy

The addition of both @vitest/coverage-istanbul and nyc seems redundant as they serve similar purposes. Consider using only one coverage reporting tool to avoid confusion and potential conflicts.

Additionally, consider pinning exact versions (^ allows minor updates) to ensure consistent builds:

-    "@vitest/coverage-istanbul": "^2.1.5",
-    "happy-dom": "^15.11.6",
-    "nyc": "^17.1.0",
-    "unplugin-auto-import": "^0.18.5",
-    "vitest": "^2.1.5",
+    "@vitest/coverage-istanbul": "2.1.5",
+    "happy-dom": "15.11.6",
+    "nyc": "17.1.0",
+    "unplugin-auto-import": "0.18.5",
+    "vitest": "2.1.5",

Also applies to: 368-368, 371-371, 385-386

packages/urlstate/useUrlStateBase/useUrlStateBase.test.ts (2)

3-3: Remove commented out import statement

The commented import from testUtils appears to be unused and should be removed to maintain clean code.

-// import { advanceTimersByTime } from '../../../tests/testUtils';

45-52: Consider grouping related cleanup operations

The afterEach block contains a good mix of cleanup operations. Consider grouping them by functionality for better readability:

 afterEach(() => {
   // Reset mocks
   router.push.mockReset();
   router.replace.mockReset();
+
   // Reset Vitest state
   vi.resetModules()
   vi.restoreAllMocks()
+
   // Reset timers and globals
   vi.useRealTimers()
   vi.unstubAllGlobals();
 })

packages/example-nextjs14/.eslintrc.json (2)

3-3: LGTM! Verify monorepo structure.

Setting root: true is appropriate for preventing ESLint config inheritance in a monorepo structure.

✅ Verification successful

Setting root: true is correct and properly configured

The root: true setting in packages/example-nextjs14/.eslintrc.json is correctly configured as:

  • The repository follows a monorepo structure with multiple packages
  • The root .eslintrc.cjs explicitly ignores the nextjs14 package
  • The package uses Next.js specific ESLint configuration which should be isolated
🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify monorepo structure and ESLint configurations
# Expected: Multiple package directories and consistent ESLint configurations

# Check for package.json files to confirm monorepo structure
fd package.json packages/

# Check for other ESLint configs to ensure consistency
fd .eslintrc packages/

Length of output: 270


Script:

#!/bin/bash
# Let's check for all ESLint config files including .eslintrc.* variations

4-6: Please document the rationale for disabling react/display-name.

While disabling this rule is sometimes necessary (e.g., when using HOCs or dynamic components extensively), it can impact component debugging. Could you explain the specific use case that requires this change?

✅ Verification successful

Based on the search results, I can see that there are several React components using React.memo() and anonymous components, particularly in the codebase. The most notable examples are:

  1. RefreshButton in packages/shared/components/Refresh.tsx
  2. Status component in packages/example-nextjs14/src/app/Status.tsx

These components use React.memo() with anonymous function components, which would trigger ESLint's react/display-name rule. Disabling this rule makes sense in this context because:

  1. The components are already named through their export declarations
  2. The components are wrapped in React.memo() for performance optimization
  3. The debugging experience isn't significantly impacted as the component names are clear from their exports

The ESLint rule disable is justified for this codebase's architecture and component patterns.

4-23: Verify Jest to Vitest migration completeness

While the Vitest configuration looks good, let's ensure all Jest-specific code has been properly migrated.

.eslintrc.cjs (1)

25-25: Consider the implications of disabling react/display-name.

While this change aligns with the configuration in packages/example-nextjs14, disabling this rule could impact component debugging and React DevTools experience. Could you clarify the motivation behind this change?

Let's verify the consistency of this rule across the codebase:

If this change is necessary, consider:

  1. Adding a comment explaining why the rule is disabled
  2. Limiting the scope to specific files/patterns using overrides if possible
✅ Verification successful

Disabling react/display-name is consistent with existing configurations

The change is consistent with the configuration in packages/example-nextjs14/.eslintrc.json where the same rule is disabled. Additionally, the root configuration explicitly ignores the Next.js example packages, so this change maintains consistency across the non-example parts of the codebase.

🏁 Scripts executed

The following scripts were executed for the analysis:

Let's ensure the Google Analytics ID is consistently used across the application and that there are no conflicting analytics configurations.

✅ Verification successful

Let me check the actual analytics configurations to ensure there are no conflicts.


Analytics configuration is properly implemented with complementary services

The analytics setup is correctly configured with both Google Analytics and Vercel Analytics working complementarily:

  • Google Analytics (via @next/third-parties) is configured with a unique ID and only runs in production
  • Vercel Analytics is properly configured to run only on Vercel deployments
  • Both packages are correctly listed in dependencies
  • No conflicting configurations found between Next.js 14 and 15 examples

8-8: Good use of React.memo for performance optimization!

The memoization is well-applied here since the component renders primarily based on props and contains expensive operations like JSON.stringify.


Line range hint 8-52: Verify the impact of memoization

Let's verify if this component is being rendered frequently enough to benefit from memoization.

✅ Verification successful

Based on the search results from the previous scripts, I can make a determination about the memoization:

Memoization is justified in this case

The evidence shows that:

  • The Status component is used within Suspense boundaries and ErrorBoundaries in multiple places
  • It's rendered alongside a Form component that likely triggers updates
  • It receives URL search params (sp) and className props that could change
  • There are test cases specifically for remounting the component (Status-for-test.tsx files)
  • It's used in a data display context where preserving render performance is important

The memoization helps prevent unnecessary re-renders when parent components update or when sibling Form components trigger state changes, making it a worthwhile optimization in this case.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Search for parent components that might trigger re-renders
rg -l "Status.*" --type tsx

# Check for potential prop changes in parent components

20-20: LGTM! Vitest types integration looks correct.

The addition of "vitest/globals" aligns with the migration from Jest to Vitest and will provide the necessary type definitions for test files.

packages/urlstate/useSharedState/useSharedState.ts (1)

Line range hint 1-85: Overall implementation looks solid

The hook implementation follows React best practices with proper:

  • Memoization using useCallback
  • Cleanup in useInsertionEffect
  • Type safety considerations
  • Clear documentation
packages/urlstate/encoder/encoder.ts (2)

13-14: LGTM! Good defensive programming practice.

Early return for non-serializable types (function and symbol) prevents potential JSON.stringify errors and improves code robustness.


19-19: Verify browser compatibility for structuredClone.

While using structuredClone is good for preventing mutations, please consider:

  1. Browser compatibility - ensure your target browsers support it
  2. Performance impact for large objects - consider adding size limits or fallback mechanisms
✅ Verification successful

Browser compatibility for structuredClone is sufficient for the target browsers

The package's browserslist configuration in package.json targets modern browsers:

  • Last 5 versions of Chrome and Firefox
  • Firefox ESR
  • Last 2 major versions of Safari and iOS

structuredClone is well-supported in these target browsers, being available since:

  • Chrome 98+
  • Firefox 94+
  • Safari 15.4+

The implementation is also used consistently across the codebase for deep cloning objects, particularly in tests and encoding logic, indicating it's a deliberate choice for the library's functionality.

Script:

#!/bin/bash

105-106: LGTM: Good use of structuredClone!

The replacement of a custom clone function with the native structuredClone is a good improvement:

  • More reliable deep cloning
  • Better standardization
  • Improved maintainability

Also applies to: 119-120, 123-124


129-131: ⚠️ Potential issue

Verify mock reset behavior after migration

The change from jest.resetAllMocks() to vi.resetModules() might not provide equivalent functionality:

  • jest.resetAllMocks() resets mock state
  • vi.resetModules() resets the modules registry

Consider using vi.resetAllMocks() instead to maintain the same behavior.

✅ Verification successful

Mock reset implementation is consistent with other test files

Looking at the codebase, the use of vi.resetModules() is consistent with other test files in the project. In fact, other test files like useSharedState.test.ts and useUrlStateBase.test.ts use vi.resetModules() along with vi.restoreAllMocks() for a complete reset of both modules and mocks. The current implementation follows the project's established patterns for Vitest.

19-20: Optimize cleanup sequence in afterEach

Consider reversing the order of cleanup operations for better reliability:

  afterEach(() => {
-   vi.resetModules()
-   vi.restoreAllMocks()
+   vi.restoreAllMocks()
+   vi.resetModules()
  })

This ensures that mocks are properly restored before module state is reset.


Line range hint 35-37: Enhance readability of spy assertions

Consider using not.toHaveBeenCalled() instead of toHaveBeenCalledTimes(0) for better readability:

- expect(stateSpy).toHaveBeenCalledTimes(0);
- expect(stateSpySet).toHaveBeenCalledTimes(0);
+ expect(stateSpy).not.toHaveBeenCalled();
+ expect(stateSpySet).not.toHaveBeenCalled();

Line range hint 184-195: Enhance subscriber notification test coverage

Consider expanding the test to verify:

  1. The actual value passed to the subscriber
  2. Multiple state updates
  3. The order of notifications

Example:

test('should notify subscribers when state changes', () => {
  const defaultState = { count: 0 };
  const { result } = renderHook(() => useSharedState(defaultState));
  const mockSubscriber = vi.fn();

  subscribers.subscribers.add(defaultState, mockSubscriber);

  act(() => {
    result.current.setState({ count: 5 });
  });
  expect(mockSubscriber).toHaveBeenCalledWith({ count: 5 });

  act(() => {
    result.current.setState({ count: 10 });
  });
  expect(mockSubscriber).toHaveBeenCalledTimes(2);
  expect(mockSubscriber).toHaveBeenLastCalledWith({ count: 10 });
});

Line range hint 262-269: Consider serialization implications and add type documentation

  1. The Date object in the tags array might cause serialization issues when the state is shared or persisted. Consider using ISO string or timestamp instead.
  2. Add JSDoc comments to document the purpose and constraints of each field.

Example:

/** Represents user form data with personal information and preferences */
type Form = {
  /** User's full name */
  name: string;
  /** User's age (optional) */
  age?: number;
  /** Whether user has agreed to terms and conditions */
  agree_to_terms: boolean;
  /** List of user-selected tags with timestamps */
  tags: {
    id: string;
    value: {
      text: string;
      // Consider using string | number instead of Date
      time: Date;
    }
  }[];
};
packages/urlstate/encoder/encoder.test.ts (4)

14-30: Consider making date tests timezone-independent

The test might fail in different timezones because it uses new Date(2024, 10, 1) which is timezone-dependent. Consider using new Date('2024-11-01T00:00:00.000Z') for consistent results across different environments.

-const obj1 = { num: 123, float: 1.55, bool1: false, und: undefined, date: new Date(2024, 10, 1) };
+const obj1 = { num: 123, float: 1.55, bool1: false, und: undefined, date: new Date('2024-11-01T00:00:00.000Z') };

38-52: LGTM on structuredClone usage, but dates need timezone independence

The use of structuredClone is a good practice for deep copying. However, the same timezone issue exists with new Date(2019, 1, 1) and new Date(2021, 1, 1).

-dateObj: new Date(2019, 1, 1),

Line range hint 267-273: Remove console.log and consider moving performance test

The console.log statement should be removed from the test. Consider moving the performance measurement to a separate benchmark suite or using proper performance testing tools.

-const a1 = performance.now();
 const result = decode(encode(bigObj));
-const a2 = performance.now();
-console.log('encode time', a2 - a1 + ' milliseconds');
 expect(result).toStrictEqual(bigObj);

Line range hint 277-294: Improve test descriptions and type handling

The test descriptions could be more descriptive, and the type casting approach could be improved:

  1. "should encode with specia symbols" has a typo and unclear purpose
  2. "should value for other types" is grammatically incorrect
  3. Type casting with as unknown as string could be replaced with proper typing
-test('should encode with specia symbols', () => {
+test('should handle special symbols for undefined and dates', () => {

-test('should value for other types', () => {
+test('should preserve values for various primitive types', () => {

-expect(decodePrimitive(null as unknown as string)).toStrictEqual(null);
+expect(decodePrimitive('null')).toStrictEqual(null);

Line range hint 1-420: Ensure test coverage configuration is updated

The migration from Jest to Vitest requires updating the test coverage configuration. Please verify that a Vitest configuration file exists with appropriate coverage settings.

Let's check for the configuration:

✅ Verification successful

Test coverage configuration is properly set up

The Vitest configuration file (vitest.config.ts) already includes comprehensive coverage settings using Istanbul provider, with appropriate reporting formats (lcov, json, html) and output directory configuration.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify Vitest configuration exists and includes coverage settings

# Look for Vitest config files
fd -g "vitest.config.*"

# Check if coverage is configured in any other config files
rg -l "coverage|vitest" -g "*.config.*"

Length of output: 101


Script:

#!/bin/bash
# Check the content of vitest.config.ts for coverage configuration
cat vitest.config.ts

Length of output: 580

2-2: Good choice switching to esbuild!

The transition from terser to esbuild and the addition of JSON import assertions are solid improvements:

  • esbuild provides significantly faster builds compared to terser
  • The JSON module assertion follows the latest ECMAScript standards and improves type safety

Consider adding the following to maximize esbuild's benefits:

  • Add a treeShaking: true option to further optimize bundle size
  • Consider using esbuild for TypeScript transpilation instead of @rollup/plugin-typescript for even faster builds

28-32: Verify browser compatibility with ES2023 target

The esbuild configuration looks good, but the ES2023 target might be too aggressive depending on your browser support requirements.

Let's check the project's browser support requirements:

✅ Verification successful

Browser compatibility target aligns with project requirements

The project has explicit browserslist configuration targeting modern browsers:

  • Last 5 versions of Chrome and Firefox (desktop & Android)
  • Firefox ESR
  • Last 2 major versions of Safari (desktop & iOS)

These modern browser targets fully support ES2023 features, making the current esbuild configuration appropriate for the project's requirements.

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check browser targets configuration and package.json for browserslist

# Check for browserslist config
echo "Checking for browserslist configuration..."
rg -l "browserslist"

# Check package.json for browser/engines fields

Line range hint 353-386: Clean up remaining Jest dependencies in workspace packages

While the root package.json has been updated with Vitest dependencies, workspace packages might still contain Jest-related dependencies that should be removed.


148-148: Verify test files compatibility with Vitest

The test command has been updated to use Vitest, which is good. However, based on previous reviews, there might still be Jest-style assertions in the test files that need to be updated.

Let's verify the test files migration status:


165-165: Verify Rollup configuration migration completeness

The Rollup configuration has been updated to use .mjs extension, supporting ES modules. Ensure this change is consistent across the workspace packages.

Also applies to: 290-290

✅ Verification successful

Rollup configuration migration is complete and consistent

The codebase has been fully migrated to use the .mjs extension for Rollup configuration. There is only one Rollup config file (rollup.config.mjs) and all references to it are consistent, using the .mjs extension in the package.json scripts.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Check for any remaining .js Rollup configs

# Find any Rollup config files still using .js extension
