Walkthrough

A modification was made in the applyPlugins function within packages/nuxt/src/app/nuxt.ts. Specifically, in the catch block that handles errors occurring during plugin execution, the code was updated to throw the caught error instance e directly instead of throwing a previously declared variable error. No changes were made to the declarations or signatures of exported or public entities.

Timestamp: 2024-11-05T15:22:54.759Z
Learning: In `packages/nuxt/src/components/plugins/loader.ts`, the references to `resolve` and `distDir` are legacy code from before Nuxt used the new unplugin VFS and will be removed.

Timestamp: 2025-04-18T18:33:41.753Z
Learning: In Nuxt, using `rolldownVersion` (not `rollupVersion`) is intentional when detecting if rolldown-vite is being used, even though TypeScript may show an error because the property isn't in standard type definitions yet.

Timestamp: 2024-11-28T21:22:40.496Z
Learning: In `packages/kit/src/template.ts`, when updating the `EXTENSION_RE` regular expression for TypeScript configuration, avoid using patterns like `(\.\w+)+$` as they can result in catastrophic backtracking.

448-448: Excellent fix for the undefined variable bug!

This change correctly throws the caught error e instead of the error variable, which would be undefined at this point in execution since the assignment error ||= e happens on line 450, after the throw statement.
