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 focuses on updating the project's documentation to reflect recent changes in how chunk splitting is configured. It ensures that all references and code examples correctly use the splitChunks option, replacing the older performance.chunkSplit. The updates also clarify how specific plugins, like those for React and Vue, interact with the new default chunk splitting presets, providing a more consistent and accurate guide for users.

Highlights

  • Configuration Update: Migrated documentation and code examples from the deprecated performance.chunkSplit option to the new splitChunks configuration.
  • Plugin Documentation Clarity: Enhanced the React and Vue plugin documentation to accurately describe their chunk splitting behavior using the new default preset.
  • Outdated Link Removal: Eliminated references and links to the performance.chunkSplit configuration that are no longer relevant.

Code Review

This pull request successfully updates the documentation to replace the deprecated performance.chunkSplit with the new splitChunks option. The changes are consistently applied across both English and Chinese documentation, including code examples and reference links. I've identified one minor issue in the Chinese documentation where a code comment was inadvertently changed to English. Besides this, the updates are accurate and well-executed.
