Summary of Changes

Hello, 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 performs a comprehensive renaming operation, changing all instances of 'webpack-dev-server' to 'rspack-dev-server' across the codebase. This ensures consistency in branding and naming conventions, impacting client-side logic, server-side routing, and various testing configurations.

Highlights

• Client-side References: Updated all client-side code to use 'rspack-dev-server' instead of 'webpack-dev-server' for hot module replacement, live reload, and overlay elements.
• Server-side References: Renamed server middleware paths and names, including those for the SockJS bundle, invalidation, and the open-editor functionality, to reflect 'rspack-dev-server'.
• Test Updates: Modified end-to-end tests, including snapshots, built-in routes, hot/live reload, and overlay tests, to align with the new 'rspack-dev-server' naming convention.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request begins the refactoring process of renaming webpack-dev-server to rspack-dev-server. The changes made in the diff are correct. However, the refactoring seems incomplete as there are several other occurrences of the old name throughout the codebase. Since these are outside the changed lines in this pull request, I'm listing them here for your consideration to address in a follow-up:

• src/server.ts: Several references to webpack-dev-server remain.

  • Environment variables WEBPACK_DEV_SERVER_BASE_PORT (line 326) and WEBPACK_DEV_SERVER_PORT_RETRY (line 333) could be renamed to use an RSPACK_ prefix.
  • The IPC socket name webpack-dev-server.sock (line 1092) should be rspack-dev-server.sock.
  • An error message on line 1436 contains a path with webpack-dev-server.

• tests/e2e/hot-and-live-reload.test.js:

  • The constant INVALID_MESSAGE on line 20 is [webpack-dev-server] App updated. Recompiling... and should be updated.

• tests/e2e/__snapshots__/overlay.test.js.snap.webpack5:

  • The snapshot contains multiple instances of <h1>webpack-dev-server is running...</h1> which should be updated. This likely originates from a test fixture that also needs to be updated.

• client-src/utils/sendMessage.ts:

  • The postMessage event type prefix is still webpack on line 19. This could be changed to rspack for consistency.

• client-src/modules/logger/Logger.ts:

  • The class WebpackLogger and its related symbols and error messages could be renamed to use Rspack for consistency.
