Created with StackBlitz ⚡️

Setup

pnpm install

Repro

pnpm run reset
pnpm run hijack

Reset

Option A: Run Vitest from the SvelteKit package directory.
Option B: Build SvelteKit.

Afterwards, inspect SvelteKit's internal tsconfig.json

Expected & actual output:

{
  "paths": {
    "$myAlias": ["../src/myAlias"],
    "$myAlias/*": ["../src/myAlias/*"],
    "$lib": ["../src/lib"],
    "$lib/*": ["../src/lib/*"]
  },
  "rootDirs": ["..", "./types"]
}

Hijack

Option A: Run Vitest from the root directory.
Option B: With the VSCode "Vitest" extension running, modify or touch e.g. the root package.json.

Afterwards, again inspect SvelteKit's internal tsconfig.json

Actual (unexpected) output:

{
  "paths": {
    "$myAlias": ["../../z-another-app/src/myAlias"],
    "$myAlias/*": ["../../z-another-app/src/myAlias/*"],
    "$lib": ["../src/lib"],
    "$lib/*": ["../src/lib/*"]
  },
  "rootDirs": ["../../z-another-app", "./types"]
}

Notes

SvelteKit's Vite is configured with an extra plugin that logs process.cwd() and server.config.root.

During reset/hijack, check STDOUT for [cwd-vs-config-root] ... lines.

Logs during reset:

[cwd-vs-config-root] PROCESS CWD: /path-to-repo/packages/my-app
[cwd-vs-config-root] CONFIG ROOT: /path-to-repo/packages/my-app

Logs during hijack:

[cwd-vs-config-root] process.cwd: /path-to-repo/packages/z-another-app
[cwd-vs-config-root] config.root: /path-to-repo/packages/my-app
