3-9: Verify error handling andRunner.preLoadmethod implementation.The new
preLoadfunction introduces specific error handling by modifying the error message. Ensure that the error objecteis always an instance ofErrorto safely modify its message property. Additionally, verify that theRunnerclass'spreLoadmethod correctly handles thedependenciesparameter and integrates well with this function.core/types/lifecycle/EggObjectLifecycle.ts (1)
7-10: Approve addition ofpreStandaloneLoadmethod.The new
preStandaloneLoadmethod enhances lifecycle management capabilities by allowing for pre-loading logic. Ensure that all implementations of theEggObjectLifecycleinterface handle the optional nature of this method correctly, and consider adding default behavior or documentation on how to implement it effectively.core/lifecycle/src/decorator/index.ts (1)
13-22: ApprovecreateStaticLifecyclefunction and suggest verification.The new
createStaticLifecyclefunction is well-designed for creating lifecycle hooks for static methods. Verify the integration with existing lifecycle management utilities to ensure that the lifecycle hooks are correctly registered and triggered.Verification successful
Integration of
createStaticLifecyclewith Lifecycle Management Utilities VerifiedThe
createStaticLifecyclefunction is correctly integrated with the lifecycle management utilities through the use ofLifecycleUtil.setLifecycleHook. The function is designed to register lifecycle hooks for static methods, and its implementation aligns with this purpose. No issues were found in the integration.Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Description: Verify the integration of `createStaticLifecycle` with existing lifecycle management utilities. # Test: Search for the usage of `LifecycleUtil.setLifecycleHook` in the context of `createStaticLifecycle`. rg --type typescript -A 5 $'LifecycleUtil.setLifecycleHook'Length of output: 93

standalone/standalone/test/fixtures/lifecycle/foo.ts (1)
13-70: Comprehensive Review of ClassFooThe class
Foois well-structured with appropriate use of lifecycle decorators. Each method is correctly implemented to handle specific lifecycle events. The use of static forpreStandaloneLoadand instance methods for other lifecycle events is consistent with typical usage patterns in frameworks like Egg.js.However, the method
initat lines 48-50 is not decorated and contains a misleading log statement. This might be an oversight or intentional for debugging. It's recommended to clarify this method's purpose or correct its implementation if it's meant to be part of the lifecycle.Consider verifying the actual usage and impact of the
initmethod in the lifecycle to ensure it behaves as expected.core/lifecycle/src/LifycycleUtil.ts (1)
101-105: Review of MethodgetStaticLifecycleHookThe addition of the
getStaticLifecycleHookmethod is a valuable enhancement to theLifecycleUtilclass. It correctly usesSymbol.forto ensure the uniqueness of lifecycle hooks and leveragesMetadataUtil.getMetaDatafor retrieving metadata, which aligns with the framework's standards.This method facilitates easier and more efficient retrieval of lifecycle metadata in a static context, which can significantly improve the management of lifecycle events in larger applications.
standalone/standalone/test/index.test.ts (1)
279-300: Review of New Lifecycle TestsThe new test suite titled "lifecycle" is a significant addition to the test file. It includes comprehensive tests for the
preLoadandmainfunctions, ensuring that the lifecycle methods are invoked in the correct order and behave as expected.The use of
deepStrictEqualin line 287 to verify the static method invocation is particularly noteworthy, as it ensures that the lifecycle methodpreStandaloneLoadis correctly triggered and modifies the static state as intended.Overall, these tests are well-implemented and provide essential coverage for the new lifecycle functionality.

1-1: Review import statements.The import of
deepStrictEqualfromnode:assertandpreLoadfrom the parent module are appropriate for the new tests added. Ensure that these imports are used correctly in the test cases.
280-307: Review new test suite "lifecycle".The new test suite "lifecycle" includes two test cases:
preLoad should work: This test case checks that thepreLoadfunction correctly invokes a static method on theFooclass, asserting thatFoo.staticCalledcontains the expected value.should work: This test case verifies that themainfunction returns an array of lifecycle method names in the correct order.Both test cases are well-structured and use
deepStrictEqualfor assertions, which is suitable for comparing complex objects or arrays. The use ofrequireinside abeforeEachblock to dynamically load theFooclass is a good practice to ensure that the module is reloaded before each test, avoiding state leakage between tests.However, the comment from the previous review by "killagu" suggests that there might be an expectation for a
preloadfunction or similar functionality. It's important to verify if this has been addressed adequately in the new test cases.Run the following script to verify if the
preloadfunction or similar functionality is adequately addressed:Verification successful
Verification of
preLoadFunctionalityThe
preLoadfunction is adequately addressed in the codebase. It is defined and used in multiple locations, including the test suite and the main application logic. The function is part of the lifecycle management, and its usage in the test suite aligns with its intended functionality.
- Definition and Usage:
- The
preLoadfunction is defined instandalone/standalone/src/main.tsand is used in the test suitestandalone/standalone/test/index.test.ts.- It is also part of the lifecycle hooks in
standalone/standalone/src/Runner.ts, where it is invoked as part of the lifecycle management process.The test suite correctly tests the
preLoadfunctionality, ensuring that it is invoked and behaves as expected. The previous review comment's concern about thepreloadfunction has been addressed, as thepreLoadfunction is implemented and tested.Scripts executed

13-13: LGTM!The changes to the
buildAppGraphmethod are approved:
- Changing it from a private instance method to a private static method enhances modularity and clarity.
- Adding the
moduleReferencesparameter makes the method more reusable by explicitly passing the necessary data.Also applies to: 15-15
30-30: LGTM!The changes to the
loadmethod are approved:
- Changing it from an instance method to a private static method enhances modularity and clarity.
- Taking
moduleReferencesas an argument instead of relying on the instance's property makes the method more reusable by explicitly passing the necessary data.- Updating the invocation of
buildAppGraphwithinloadensures that the method works correctly in the new static context.Also applies to: 33-33
49-53: LGTM!The addition of the
preLoadmethod is approved:
- It expands the functionality of the class by introducing a pre-loading mechanism that was not previously present.
- The method enhances the modularity of the class by separating the pre-loading logic from the main loading process.
standalone/standalone/test/index.test.ts (2)
290-293: LGTM!The test case "preLoad should work" is approved:
- It ensures that the
preLoadfunction is working as intended by validating the invocation of the static method on theFooclass.- The assertion verifies that the expected value is present in
Foo.staticCalled, confirming the correct behavior of thepreLoadfunction.
295-306: LGTM!The test case "should work" is approved:
- It ensures that the overall behavior of the
mainfunction is working as intended by validating the order of the lifecycle method invocations.- The assertion verifies that the expected values are present in
Foo.staticCalledin the correct order, confirming the correct behavior of themainfunction.

core/types/lifecycle/LifecycleHook.ts (1)
7-7: LGTM!The addition of the optional
preLoadmethod to theLifecycleObjectinterface is a valid change that enhances the lifecycle management capabilities. The method signature correctly indicates that it is intended for asynchronous operations that may need to occur before the main lifecycle methods. The change is also backward compatible as the method is marked as optional.standalone/standalone/src/EggModuleLoader.ts (3)
Line range hint
13-28: LGTM!The change of the
buildAppGraphmethod from a private instance method to a private static method is a valid refactor that enhances the method's reusability and clarity by explicitly passing the necessary data. The additionalmoduleReferencesparameter is correctly typed and used within the method. The change is not breaking as the method is private and not part of the public API.
Line range hint
30-43: LGTM!The change of the
loadmethod from an instance method to a private static method is a valid refactor that enhances the method's reusability and clarity by explicitly passing the necessary data. ThemoduleReferencesargument is correctly typed and used within the method. The updated invocation ofbuildAppGraphcorrectly reflects the new static context. The change is not breaking as the method is private and not part of the public API.
45-55: LGTM!The addition of the static
preLoadmethod is a valid change that expands the functionality of theEggModuleLoaderclass, allowing for a pre-loading mechanism that was not previously present. The method correctly uses the staticloadmethod to load the modules and iterates over the results to callpreLoadon each load unit if it exists. The method is correctly marked asasyncand returns aPromise<void>.core/metadata/src/impl/ModuleLoadUnit.ts (1)
185-193: LGTM!The addition of the asynchronous
preLoadmethod to theModuleLoadUnitclass is a valid change that enhances the lifecycle management capabilities by allowing for pre-loading operations on classes. The method correctly usesthis.loader.load()to load the classes and iterates over each class to find and call the correspondingpreLoadlifecycle hook if it exists. The method is correctly marked asasyncand returns aPromise<void>.standalone/standalone/test/index.test.ts (2)
280-307: LGTM!The new
describeblock titled "lifecycle" adds comprehensive test coverage for the new lifecycle functionality. The test cases cover the expected behavior of thepreLoadfunction and the overall lifecycle flow. Clearing therequire.cacheensures that each test case starts with a fresh instance of theFooclass, preventing any potential side effects from previous tests.The code changes are well-structured and follow best practices for writing unit tests.
1-5: LGTM!The updated import statements are necessary to support the new test cases added in the "lifecycle"
describeblock.deepStrictEqualis used for asserting the equality of arrays, andpreLoadis the function being tested.
