7-7: Update the SvelteKit documentation linkThe link to SvelteKit in the documentation points to the general Svelte site. Updating it to the specific SvelteKit documentation will provide more direct and relevant information.
Apply this diff to correct the link:
* - * [SvelteKit]: https://svelte.dev/ + * [SvelteKit]: https://kit.svelte.dev/ * * @module */
31-31: Correct the import path in the documentation exampleIn the example, the import statement uses
"federation.ts", which may not reflect the actual module path. Ensure the import path is accurate so developers can follow the example without confusion.Consider updating the import statement:
* ``` typescript -import { federation } from "federation.ts"; // Import the `Federation` object +import { federation } from "../federation/federation.ts"; // Import the `Federation` object * * export const handle = fedifyHook(federation, () => undefined); * ```

60-88: Ensure FederationFetchOptions methods match expected signatures
The methods onNotFound and onNotAcceptable inside integrateFetchOptions should align with the expected signatures defined in FederationFetchOptions. Verify that these implementations are correctly typed and handle all necessary parameters.
Please confirm that the FederationFetchOptions interface expects methods with these signatures. If discrepancies exist, adjust the method implementations accordingly.

1-10: Enhance module documentation with more detailsWhile the documentation provides a basic overview, consider adding:
- Purpose and benefits of the integration
- Content negotiation behavior
- Configuration options and examples
- Error handling scenarios
/** * Fedify with SvelteKit * ================ * * This module provides a [SvelteKit] middleware to integrate with the Fedify. + * + * ## Features + * - Seamless integration between Fedify and SvelteKit + * - Content negotiation based on Accept headers + * - Fallback to SvelteKit's default handling for non-federation requests + * + * ## Configuration + * The integration can be configured through the `fedifyHook` function parameters: + * - `federation`: The Federation instance to handle requests + * - `createContextData`: Custom function to provide context data * * [SvelteKit]: https://svelte.dev/ * * @module */
29-34: Enhance example with more realistic use caseThe current example is minimal. Consider expanding it to show:
- Context data creation
- Error handling
- Content negotiation scenarios
* @example hooks.server.ts * ``` typescript * import { federation } from "federation.ts"; // Import the `Federation` object + * + * // Example context creation + * const createContext = (event: RequestEvent) => ({ + * user: event.locals.user, + * // Add other context data + * }); * - * export const handle = fedifyHook(federation, () => undefined); + * export const handle = fedifyHook(federation, createContext); + * + * // The hook will: + * // 1. Handle federation requests with JSON-LD responses + * // 2. Fall back to SvelteKit for HTML responses + * // 3. Return 406 Not Acceptable when content negotiation fails * ```
75-85: Consider enhancing error handling in onNotAcceptableWhile the current implementation handles 404 status, consider:
- Adding error logging for debugging
- Handling other error status codes explicitly
- Including more detailed error messages
async onNotAcceptable(): Promise<Response> { const res = await resolve(event); - if (res.status !== 404) return res; + // Handle specific error cases + switch (res.status) { + case 404: + return new Response("Not acceptable - Resource not found", { + status: 406, + headers: { + "Content-Type": "text/plain", + Vary: "Accept", + "X-Error-Code": "RESOURCE_NOT_FOUND" + }, + }); + case 500: + // Log internal errors but return generic message + console.error("Internal error during content negotiation"); + return new Response("Not acceptable - Internal error", { + status: 406, + headers: { + "Content-Type": "text/plain", + Vary: "Accept", + "X-Error-Code": "INTERNAL_ERROR" + }, + }); + default: + return res; + } - return new Response("Not acceptable", { - status: 406, - headers: { - "Content-Type": "text/plain", - Vary: "Accept", - }, - }); },CHANGES.md (1)

43-54: Verify error handling with Federation framework
The integration looks solid, but let's verify proper error propagation between SvelteKit and Federation.
✅ Verification successful
Error handling is properly implemented in the Federation framework
The integration between SvelteKit and Federation has robust error handling:
- Federation middleware implements comprehensive error handling with proper logging and error propagation
- Errors are caught at multiple levels (JSON parsing, activity processing, signature verification)
- Custom error handlers (
inboxErrorHandler,onOutboxError) allow customization of error handling - HTTP status codes and error responses are properly set for different error scenarios
- Error states are logged with appropriate context for debugging

💡 Codebase verification
The SvelteKit integration needs better documentation coverage
The current documentation for SvelteKit integration is limited to code comments in src/x/sveltekit.ts. While these comments provide basic usage examples, the integration should be documented in the main integration manual alongside other frameworks like Express, Hono, h3, and Fresh.
- Add SvelteKit section to
docs/manual/integration.md - Include detailed explanation of
fedifyHookmiddleware functionality - Document configuration options and content negotiation behavior
- Add code examples similar to other framework integrations
- Consider adding a SvelteKit-specific tutorial or example
🔗 Analysis chain
Enhance the SvelteKit integration documentation.
The changelog entry for SvelteKit integration is quite brief. Consider adding more details about:
- The functionality provided by the
fedifyHookmiddleware - Configuration options and usage examples
- Any limitations or considerations when using SvelteKit integration
Let's check if there's any documentation for the SvelteKit integration:
Let me check the content of the SvelteKit integration file to see if there's sufficient documentation.
Let me check if there's any SvelteKit integration documentation in the manual or tutorial sections.

1-11: Enhance module documentation with more examplesThe module documentation is well-structured, but consider adding:
- Examples of different context data scenarios
- Common use cases for federation integration
- Error handling examples
46-58: Consider enhancing error handling and type safetyThe implementation could benefit from:
- Adding try-catch block to handle potential errors from
createContextData- Adding runtime validation for the federation object
Consider applying this improvement:
export function fedifyHook<TContextData>( federation: Federation<TContextData>, createContextData: ( event: RequestEvent, ) => TContextData | Promise<TContextData>, ): (params: HookParams) => Promise<Response> { return async ({ event, resolve }: HookParams) => { + try { + const contextData = await createContextData(event); return await federation.fetch(event.request, { - contextData: await createContextData(event), + contextData, ...integrateFetchOptions({ event, resolve }), }); + } catch (error) { + console.error('Error in fedifyHook:', error); + return new Response('Internal Server Error', { status: 500 }); + } }; }docs/manual/integration.md (1)
199-214: Consider enhancing the SvelteKit integration documentation.While the basic integration is well documented, consider adding:
- A brief explanation of SvelteKit's server hooks concept
- Any specific considerations or limitations when using Fedify with SvelteKit
- Examples of common use cases or patterns

194-214: Enhance the SvelteKit integration documentation.While the section follows the document's structure well, consider these improvements to make it more comprehensive:
- Add comments explaining the expected shape and usage of the context data parameter in the code example
- Include any specific considerations or limitations when using Fedify with SvelteKit
- Add an example of how to handle errors or customize the hook behavior
Here's a suggested addition to the code example:
// This is the entry point to the Fedify hook from the SvelteKit framework: -export const handle = fedifyHook(federation, (req) => "context data"); +// The context data factory function receives the SvelteKit Request object +// and should return any data needed by your Fedify handlers +export const handle = fedifyHook(federation, (req) => { + // Example: return user session data, configuration, etc. + return "context data"; +});

199-202: Documentation aligns well with PR objectives.
The section effectively documents the SvelteKit integration, addressing Issue #171's requirements and clearly explaining the server hook implementation.
205-206: Verify the SvelteKit module exports.
Let's verify that the documented module and exports exist in the codebase.
✅ Verification successful
Documentation accurately reflects the implementation
The documentation correctly references the fedifyHook function which exists in the @fedify/fedify/x/sveltekit module. The implementation in src/x/sveltekit.ts matches the documented usage, showing both the function export and its practical application in creating a SvelteKit handle.
