> Vite, Vitest, Rolldown, tsdown, Oxlint, and Oxfmt

You already use the first, the second you should be using and has existed for years - it's a jest-compatible runner integrated to Vite.

Rolldown is a part of Vite already (since version 8, alongside other implementing tools like lightnincss).

The ox* suite are native replacements for eslint and prettier. The latter has existed for years. Both of them aim to be drop-in compatible soon.

This is a boring stack.

FWIR, prior to the purchase by Vercel (or was it Cloud flare?), Vite+ was going to be a convenient, no fuss, low movement way set up projects that they sold to businesses for funding.
