feat: createServerEntry

[TkDodo]

type-safe createServerEntry that will help with adding try/catch internally later on without users having to change a thing.

Summary by CodeRabbit

• Documentation

  • Updated server entry guide and examples to show the new wrapped export pattern and clarify request handler usage.

• Refactor

  • Server entry export now uses a lightweight wrapper/factory approach for request handlers, replacing the previous direct-object export to improve interoperability and consistency.

Walkthrough

Replaces direct server-entry object exports with a createServerEntry(factory) wrapper across React Start and Solid Start packages and updates documentation to show exporting default via createServerEntry({ fetch(...) { ... } }).

Changes

Cohort / File(s)	Summary
Documentation updates docs/start/framework/react/guide/server-entry-point.md	Reworked examples and narrative to use createServerEntry(...) from @tanstack/react-start/server-entry instead of exporting a plain ServerEntry object; updated request context and custom handler examples.
React Start server entry packages/react-start/src/default-entry/server.ts	Added export type ServerEntry = { fetch: RequestHandler<Register> }; introduced export function createServerEntry(entry: ServerEntry): ServerEntry and changed default export to export default createServerEntry({ fetch }) (removed concrete serverEntry export).
Solid Start server entry packages/solid-start/src/default-entry/server.ts	Added export type ServerEntry = { fetch: RequestHandler<Register> }; introduced export function createServerEntry(entry: ServerEntry): ServerEntry and changed default export to export default createServerEntry({ fetch }) (removed concrete serverEntry export).

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Multiple similar edits across packages and docs reduce cognitive overhead, but reviewers should verify:
  • Type signatures for ServerEntry and RequestHandler<Register> consistency
  • Default export behavior change and any downstream import sites
  • Documentation examples compile and match runtime behavior

Poem

🐰 I wrapped my fetch in cozy thread,
A little factory for calls ahead.
Now entries hop with tidy cheer,
Wrapped and ready — spring is near! 🥕

Learning: In packages/start-client-core/src/client/hydrateStart.ts, the `import/no-duplicates` ESLint disable is necessary for imports from `#tanstack-router-entry` and `#tanstack-start-entry` because both aliases resolve to the same placeholder file (`fake-start-entry.js`) in package.json during static analysis, even though they resolve to different files at runtime.

🔇 Additional comments (3)

packages/solid-start/src/default-entry/server.ts (1)

10-21: LGTM! Clean wrapper pattern for future extensibility.

The createServerEntry factory provides a type-safe abstraction that maintains the current pass-through behavior while establishing a clear extension point for adding error handling (try/catch) in the future. The async/await pattern and the helpful comment about RequestHandler import specificity are both well-considered.

packages/react-start/src/default-entry/server.ts (1)

10-21: LGTM! Consistent implementation across frameworks.

The implementation mirrors the solid-start version, providing the same type-safe wrapper pattern with future extensibility. The consistency across frameworks ensures a uniform API surface for users.

docs/start/framework/react/guide/server-entry-point.md (1)

27-27: The import path is correctly configured and verified.

The export configuration exists in packages/react-start/package.json: the ./server-entry export is properly mapped to ./dist/default-entry/esm/server.js, which corresponds to the implementation at packages/react-start/src/default-entry/server.ts. The documentation's import statement is valid.
