vite 7.1.11 causing issues CJS node builtin imports

[BlankParticle]

Describe the bug

Prior to vite 7.1.11, importing CJS libraries produced top level built-in imports

import require$$6 from "path";

but since version 7.1.11, the build output contains code like this

const require$6 = createRequire(import.meta.url);
function __require$5() {
  return require$6("node:path");
}

this in itself is not a problem in node as import.meta.url is defined in node runtime, but in runtimes like workerd, import.meta.url is undefined, which causes createRequire to throw an error

from my investigation this is likely caused by rollup cjs plugin's update (rollup/plugins#1909), which was included in this vite version

this behaviour is causing our deployments on cloudflare to fail, we have rolled back to 7.1.10 until this issue is fixed

cc @jamesopstad, you probably want to know about this as workerd is the main affected runtime

Reproduction

https://github.com/BlankParticle/vite-cjs-import-issue

Steps to reproduce

the project is setup to bundle @slack/web-api, which is the CJS lib I was using
when you build the project, you can see createRequire(import.meta.url) in the output, which is causing the issue

downgrade to 7.1.10 and it produces the correct imports

Thanks @BlankParticle for reporting and @sapphi-red for the quick fix.

[acusti]

just as another data point, i’ve been running into this on (rolldown-vite) v7.1.11 so i tried upgrading to v7.2.0-beta.0 (which seems to include the downgrade fix) and i still saw the same error, but downgrading to v7.1.10 made it go away (all rolldown-vite)

[sapphi-red]

@acusti rolldown-vite does not use the rollup commonjs plugin so I think that's a separate issue.
