📝 Walkthrough

Walkthrough

Replaces imports of @tanstack/config/vite with @tanstack/vite-config across the monorepo, updates root package.json and changeset to add @tanstack/vite-config@0.4.3, patches that package, switches a yargs import/initialization in the CLI, and adds two methods to the ServerSsr interface.

Changes

Cohort / File(s)	Summary
Changeset & Root Manifest \.changeset/tasty-falcons-say.md, package.json, patches/@tanstack__vite-config@0.4.3.patch	Adds patch changelog entries, removes @tanstack/config devDependency, adds @tanstack/vite-config@0.4.3 and a local patch file that changes TS compilerOptions.module to Node16.
Vite config import updates packages/*/vite.config.ts, packages/*/vite.config.*.ts, packages/**/.../vite.config.ts	Replaced imports of tanstackViteConfig from @tanstack/config/vite → @tanstack/vite-config across many package Vite config files; no other config logic changed.
Router core interface packages/router-core/src/router.ts	Added two methods to ServerSsr interface: setRenderFinished(): void and cleanup(): void.
CLI import/usage packages/router-cli/src/index.ts	Switched yargs from namespace to default import and initialized the CLI via yargs() (removed prior // @ts-expect-error``).

Poem

🐇 I hopped through modules, swapped each line,
From config/vite to vite-config fine.
Two hooks now waiting where SSR sits,
The CLI learns to call — no more bits.
A tiny patch, a tidy sprint of mine.
