<<<CYPRESS.STDERR.START>>>You or a plugin you are using have set `optimizeDeps.esbuildOptions` but this option is now deprecated. Vite now uses Rolldown to optimize the dependencies. Please use `optimizeDeps.rollupOptions` instead.

Desired behavior
Should be able to run as smoothly as with normal vite
Test code to reproduce
change vite with vite-rolldown latest in any component test
Cypress Version
15.2.0

@eMerzh
Did you follow the instructions in Rolldown Integration when you substituted rolldown-vite?
When I tried this in the simple Vite example https://github.com/cypress-io/github-action/tree/master/examples/component-tests I didn't get any errors.
Edit: To get the dependencies updated correctly, I needed to execute:
npm uninstall vite
npm install vite@npm:rolldown-vite@latest
then it failed. Just updating package.json manually and running npm install doesn't do it.
@eMerzh
I just scaffolded a new project and now I see the same error as you.
Repro here, after substituting "vite": "npm:rolldown-vite@latest" into example and running npm update --save
git clone --branch test/rolldown-vite https://github.com/MikeMcC399/cypress-component-testing-apps
cd cypress-component-testing-apps
cd react-vite-ts
npm ci
npm run cypress:run
According to
https://vite.dev/guide/rolldown.html#reporting-issues
Since this is an experimental integration, you may encounter issues.
https://vite.dev/guide/rolldown.html#future-plans
The rolldown-vite package is a temporary solution to gather feedback and stabilize the Rolldown integration. In the future, this functionality will be merged back into the main Vite repository.
So it may be more practical for Cypress to wait until rolldown-vite is mainstream, presumably with a new major release of Vite.
Yeah rolldown is experminental at this point, but it feels that here the issue lies within cypress, and it's a hint that it wont be compatible with the next version of vite, so i would say it's interesting to try to understand why and fix it if needed.

I see that the Cypress.io team has added the https://github.com/cypress-io/cypress/labels/CT and https://github.com/cypress-io/cypress/labels/type%3A%20feature labels, so I guess this is now queued up for when they have capacity to look at it. I'm an external contributor only though, so can't say anything about their possible scheduling.
I've updated the repro in https://github.com/MikeMcC399/cypress-component-testing-apps/tree/test/rolldown-vite/react-vite-ts to latest versions. As expected, nothing has resolved itself on its own. It's going to need development work to get it compatible. This has generally been the case for previous Vite releases as well to allow them to support component testing:
