I think there's a few errors here, but the biggest seems to be that Vite 6 is treating all .json files as being a tsconfig.json and then reloading the server when such a file changes. @dominikg had a PR out for this here: vitejs/vite#17317

[benmccann]

The changes to the esbuild plugin have been reverted so the prior issue with tsconfck is gone. We're down to two errors now:

  [chromium-dev] › client.test.js:448:2 › Invalidation › server-only load functions are re-run following forced invalidation 
  [chromium-dev] › client.test.js:461:2 › Invalidation › server-only load functions are re-run following goto with forced invalidation 

This can be reproduced locally by running playwright on just that one test (just need to do pnpm install beforehand):

packages/kit/test/apps/basics$ pnpm test:dev -g "server-only load functions are re-run following forced invalidation"

This is the line that's failing while running this route:

kit/packages/kit/test/apps/basics/test/client.test.js

Line 450 in 6056ba3

expect(await page.textContent('h1')).toBe('a: 0, b: 1');

It seems that Vite is loading the same module twice: once by the +layout.server module, then again by the +page.server module. However, it should only be loaded once by +layout.server then re-used by +page.server so that they are both incrementing the same count variable.

You can test this by adding a console.log(count) statement at the top level, spin up a dev server, and see it log twice when you access the page for the first time.

SvelteKit is now green in vite-ecosystem-ci. Upgrading to vite@6.0.0-alpha.22 should work out the issues in this PR.
