Summary of Changes

Hello @chenjiahan, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves an issue where the splitChunks configuration in the @rsbuild/plugin-vue did not work as expected with Rsbuild v1. The changes involve simplifying the internal logic for splitChunks preset detection and adding a new development dependency to enable comprehensive testing against Rsbuild 1.x, ensuring robust compatibility and correct chunk splitting behavior.

Highlights

  • Rsbuild v1 Compatibility: Ensured that the splitChunks configuration within @rsbuild/plugin-vue functions correctly when used with Rsbuild v1, addressing a previous failure.
  • Dependency Update: Added @rsbuild/core-v1 as a development dependency, aliasing @rsbuild/core@^1.7.2, to facilitate testing against Rsbuild 1.x.
  • Logic Simplification: Refined the isDefaultPreset function in splitChunks.ts by removing an unnecessary condition, simplifying the logic for detecting default splitChunks presets when performance.chunkSplit is active.
  • New Test Case: Introduced a new test case to specifically verify the splitChunks configuration behavior when @rsbuild/plugin-vue is integrated with Rsbuild v1, along with a corresponding snapshot update.

Code Review

This pull request aims to fix an issue where splitChunks configuration in @rsbuild/plugin-vue was not working correctly with Rsbuild v1. The changes include adding a dev dependency for testing against Rsbuild v1, updating a snapshot, and adding a new test case. The core logic change is in isDefaultPreset function to ensure compatibility. While the change fixes the issue for v1, it introduces a potential logic issue for newer versions. I've provided a suggestion to make the implementation more robust and consistent with Rsbuild's core logic across versions.

Pull request overview

This PR fixes a bug in @rsbuild/plugin-vue where the splitChunks configuration was not working correctly with Rsbuild v1 due to an overly restrictive conditional check.

Changes:

  • Simplified the isDefaultPreset function logic in splitChunks.ts to remove an unnecessary empty object check that prevented the plugin from working with Rsbuild v1
  • Added a test to verify splitChunks functionality with Rsbuild v1
  • Added @rsbuild/core-v1 as a dev dependency for testing compatibility
