Bug: Vite 8 runtime error for versions greater >=0.23.0 (can't access lexical declaration '__buffer_polyfill' before initialization)

[mtmacdonald]

Summary

When using the upcoming version of Vite (either the vite-rolldown package, or the Vite 8 beta package) I get a runtime error in apps that use vite-plugin-node-polyfills. Things work on version 0.22.0 of this package, but later versions break for me.

Uncaught ReferenceError: can't access lexical declaration '__buffer_polyfill' before initialization
    <anonymous> http://localhost:5173/@fs/Users/mark/pDev/docgen/node_modules/.vite/deps/vite-plugin-node-polyfills_shims_process.js

To reproduce this, use either "vite": "npm:rolldown-vite@latest" or "vite": "npm:rolldown-vite@8.0.0-beta.5" in package.json (instead of Vite 7x) and use the latest version of vite-plugin-node-polyfills.

I've seen PR139 which I think concerns fixing this, but I couldn't see any direct reference to the error details, so hope it's okay to open a ticket to capture that. I also see there is a related ticket in the Vite project on this (asking for it to be fixed here): #518.

Small update on this one: in PR189 I tried upgrading all packages to latest versions, include regenerating yarn.lock from scratch, prompted by this reply pointing out that my yarn.lock file actually had an older version of rolldown-vite.

I am now able to build my project again (albeit with some warnings about deprecated esbuild options).

I'll leave this ticket open until I've tried in another project where I faced this - if that goes well too, I'll close this ticket.

I can confirm in all my projects that I no longer see Uncaught ReferenceError: can't access lexical declaration runtime errors when using the latest versions "vite": "8.0.0-beta.8" and "vite-plugin-node-polyfills": "0.25.0".

The solution was to upgrade the Vite package.

I'll close this ticket (sorry for noise).
