Summary by CodeRabbit

  • Refactor
    • Simplified client-side hydration mechanism with a streamlined API. Hydration initialization now uses a single function call, replacing the previous multi-step process and reducing implementation complexity.

Walkthrough

The PR introduces a new clientHydrate() function that abstracts the client-side hydration process, encapsulating the retrieval of a router and rendering of the StartClient component. This function is exported from the solid-start-client package and replaces the manual multi-step hydration sequence in the default client entry point.

Changes

Cohort / File(s) Summary
Core hydration abstraction
packages/solid-start-client/src/StartClient.tsx
Added clientHydrate() export that calls hydrateStart() to obtain a router, then hydrates the app by rendering StartClient with it; imported hydrateStart and hydrate for the implementation.
Public exports
packages/solid-start-client/src/index.tsx
Added clientHydrate export from ./StartClient, replacing the previously exported hydrateStart from external module.
Client entry update
packages/solid-start/src/default-entry/client.tsx
Replaced manual hydration flow with single clientHydrate() call; removed individual imports for hydrate, hydrateStart, and StartClient.

Poem

🐰 A hydration hop so clean and neat,
One function call, the flow's complete,
No tangled chains of import cheer,
Just clientHydrate, crisp and clear!

The PR creates a new clientHydrate() function that abstracts the hydration flow and moves it into the solid-start-client shared package, then updates the client entry point to use this centralized function instead of implementing the hydration logic directly. The title is concise, specific, and clearly conveys the main architectural change without unnecessary details.

10-14: Consider adding an explicit return type annotation.

While TypeScript can infer void for this function, adding an explicit return type would improve code clarity and align with strict type safety practices.

Apply this diff to add the return type:

-export function clientHydrate() {
+export function clientHydrate(): void {
   hydrateStart().then((router) => {
     hydrate(() => <StartClient router={router} />, document)
   })
 }

As per coding guidelines.

1-1: LGTM! Clean public API consolidation.

The export statement correctly exposes both StartClient and the new clientHydrate function, providing a clean public API for the package.

packages/solid-start/src/default-entry/client.tsx (1)

1-3: LGTM! Excellent simplification of the client entry point.

The refactor successfully delegates the hydration logic to the shared clientHydrate() function, making the default entry point minimal and maintainable. This aligns well with the PR objectives of centralizing hydration logic.

packages/solid-start-client/src/StartClient.tsx (1)

2-3: LGTM! Correct imports for the hydration implementation.

The imports of hydrateStart and hydrate provide the necessary functionality for client-side hydration.

⚠️ Potential issue | 🟠 Major

Add error handling for the hydration promise.

The clientHydrate() function lacks error handling for the promise returned by hydrateStart(). If hydration fails, this will result in an unhandled promise rejection, which could silently break the application or cause confusing runtime errors.

Apply this diff to add error handling:

 export function clientHydrate() {
-  hydrateStart().then((router) => {
-    hydrate(() => <StartClient router={router} />, document)
-  })
+  hydrateStart()
+    .then((router) => {
+      hydrate(() => <StartClient router={router} />, document)
+    })
+    .catch((error) => {
+      console.error('Failed to hydrate application:', error)
+      throw error
+    })
 }

🤖 Prompt for AI Agents
In packages/solid-start-client/src/StartClient.tsx around lines 10 to 14,
clientHydrate() currently calls hydrateStart().then(...) without catching
errors; add error handling to avoid unhandled promise rejections by appending a
.catch(...) to the promise chain (or use async/await with try/catch) that logs
the error (using console.error or an existing logger) and optionally handles
fallback behavior (e.g., abort hydration or show a user-facing error), ensuring
the catch provides clear context about the hydration failure.
