🧹 Nitpick comments (12)
src/content/docs/integrate/third-party-tools/kinde-sveltekit-with-cloudflare.mdx (12)
1-5: Nitpick: Validate front matter schema.
Ensure the YAML front matter keys (page_id,title,description) align with your documentation site's expected schema. Consider adding metadata fields likesidebar_positionorcategoryif your site supports them for better navigation.
8-11: Suggestion: Use a callout component for complexity note.
Instead of a plain blockquote, leverage your MDX callout/snippet component (e.g.,<Alert type="warning">…</Alert>) to highlight the implementation complexity. It improves readability and consistency with other guides.
13-18: Optional: Clarify prerequisites.
Add explicit versions for Node.js, SvelteKit, Wrangler CLI, and specify which Cloudflare Pages target (e.g.,pages) you’re deploying to. It prevents compatibility issues for newcomers.
31-34: Combine installation commands.
You can streamline dependency installation into a single command for brevity:- ```bash - npm install @kinde-oss/kinde-auth-sveltekit - npm install -D @sveltejs/adapter-cloudflare - ``` + ```bash + npm install @kinde-oss/kinde-auth-sveltekit @sveltejs/adapter-cloudflare -D + ```
47-65: Nitpick: Consistent quoting inwrangler.toml.
You mix single- and double-quotes for environment variables. For clarity and consistency, use double quotes throughout:-[vars] -KINDE_SCOPE = 'openid profile email offline' + [vars] + KINDE_SCOPE = "openid profile email offline"Also consider updating
compatibility_dateto the latest stable date to avoid deprecation warnings.
179-183: Refactor: Uniform error response.
Bothconsole.errorandreturn json({ error: ... })are used. Consider extracting a helper for error responses to maintain a consistent JSON shape and status code across all endpoints.
185-201: Optional: Replaceswitchwith a handler map.
A lookup object reduces boilerplate and makes adding endpoints easier:const handlers: Record<string, Handler> = { login: (e) => handleLogin(e, storage, false), register: (e) => handleLogin(e, storage, true), kinde_callback: (e) => handleCallback(e, storage), logout: (e) => handleLogout(e, storage) }; return handlers[path]?.(event) ?? json({ error: 'Unknown auth endpoint' }, { status: 404 });
214-218: Nitpick: Move helper functions to a shared utils file.
Extractsha256andbase64URLEncodeintosrc/lib/utils/crypto.tsto avoid cluttering the route handler and enable reuse across other guides or modules.
365-443: Optional: Simplify client_secret logic.
Since Kinde always requires the client secret, you can remove theif (USE_PKCE && …)branch and always appendclient_secret, then conditionally appendcode_verifier. This flattens nested conditions.
445-457: Optional: Clear session cookies on logout.
After deleting tokens from KV, also clear any session cookies (Set-Cookie: session=; Max-Age=0) to fully end the user’s session client-side.
459-469: Optional: Handle circular objects insafeStringify.
For more robust error logging, consider using a library likefast-safe-stringifywhich gracefully handles circular references.
500-520: Optional: Delegate route protection tosessionHooks.
Rather than manually checkingstorage.getState('tokens'), leverage the hook-injectedevent.locals.sessionor a helperensureAuthenticated(event)to reduce duplication and centralize logic.

133-146: Suggestion: VerifysessionHooksintegration.
Confirm thatsessionHooksactually injects session data intoevent.localsbeforeresolve(event). Some hook implementations require you to capture and return its response:// e.g. const response = await sessionHooks({ event, storage }); return await resolve(event, { locals: event.locals });Please double-check the
@kinde-oss/kinde-auth-sveltekitdocs for exact usage.
220-225: Skip: Base64 URL encoding logic is correct.
This implementation properly replaces URL-unsafe characters. No changes needed.

199-204: Cryptographically secure randomness is correctly implemented
You’re already usingcrypto.getRandomValues, which satisfies the earlier recommendation to avoidMath.random(). No changes needed here.
446-504: Guard verbose logging behind a debug flag
There are multipleconsole.logcalls printing URLs, statuses, and potentially sensitive data. As noted in previous feedback, avoid verbose or secret-exposing logs in production. Wrap these logs in a debug check (e.g.if (KINDE_DEBUG === 'true') { ... }).

56-65: (Optional) Expose a debug flag in your Wrangler config
You referenceKINDE_DEBUGin the code but haven’t added it towrangler.toml. Consider adding:KINDE_DEBUG = "false"This lets users toggle detailed logs without touching source.
532-537: Enhance cookie security withSecureattribute
When setting thekinde_sessioncookie, add; Secureso it’s only sent over HTTPS. Example:- 'Set-Cookie': `kinde_session=${sessionId}; Path=/; HttpOnly; SameSite=Lax; Max-Age=2592000` + 'Set-Cookie': `kinde_session=${sessionId}; Path=/; HttpOnly; SameSite=Lax; Secure; Max-Age=2592000`

1-5: Add an explicit H1 heading.
While the frontmatter definestitle, it’s helpful for readability to include an H1 in the content itself. For example, right after the frontmatter add:# Integrating Kinde Authentication with SvelteKit on Cloudflare Pages
8-11: Convert the implementation note into an admonition.
To improve scannability, wrap the complexity note in a callout (e.g., a::: tipor::: warningblock) rather than inline text:::: tip This implementation is more complex than ideal due to Cloudflare's serverless constraints. We're working on more elegant solutions, but this guide provides a robust working implementation. :::
79-81: Log or surface missing KV binding errors.
createKindeStoragecurrently returnsnullsilently whenAUTH_STORAGEis unavailable. Consider logging or throwing to help readers diagnose misconfigurations:- if (!AUTH_STORAGE) { - return null; - } + if (!AUTH_STORAGE) { + console.error('❌ AUTH_STORAGE KV namespace is not bound in Wrangler'); + return null; + }
84-95: Avoid swallowing errors in storage adapter.
All catch blocks returnfalseornullwithout logging the underlying exception. For better debugging, logerror.message:- } catch (error) { - return false; - } + } catch (error) { + console.error('KV.setState error:', error); + return false; + }Apply similar logging in
getStateanddeleteState.
360-367: Add theSecureattribute to cookies.
When settingkinde_session, includeSecure;so browsers only send it over HTTPS:- 'Set-Cookie': `kinde_session=${sessionId}; Path=/; HttpOnly; SameSite=Lax; Max-Age=2592000` + 'Set-Cookie': `kinde_session=${sessionId}; Path=/; HttpOnly; Secure; SameSite=Lax; Max-Age=2592000`
397-404: Gate verbose logs behind the debug flag.
fetchTokensprints URLs and flags on every invocation, which may leak PII. Wrap allconsole.logcalls in:if (KINDE_DEBUG === 'true') { /* ... */ }to mirror other parts of the implementation.
462-466: Use SvelteKit’sevent.cookiesAPI.
Instead of manual regex parsing ofevent.request.headers, prefer:const sessionId = event.cookies.get('kinde_session');This is more robust and future-proof.
507-511: Remove unusedkindeAuthClientimport.
kindeAuthClientis imported but never used in this snippet. Deleting it will keep the sample focused:-import { kindeAuthClient } from '@kinde-oss/kinde-auth-sveltekit';
521-524: Simplify cookie retrieval inload().
As above, useevent.cookies.get('kinde_session')to fetch the session ID instead of regex on headers.
577-584: Consolidate token refresh logic.
You duplicate an OAuth token-refresh flow here. Consider reusingfetchTokens(withgrant_type=refresh_token) or extracting shared logic into a helper to avoid drift.

154-158:⚠️ Potential issueMissing import for
KINDE_DEBUG
You’ve added aKINDE_DEBUGvariable in your Wrangler config but are not importing it here. Without it, you cannot guard debug logs. Add to the import:-import { KINDE_ISSUER_URL, KINDE_CLIENT_ID, KINDE_CLIENT_SECRET, KINDE_REDIRECT_URL, KINDE_POST_LOGIN_REDIRECT_URL, KINDE_POST_LOGOUT_REDIRECT_URL, KINDE_AUTH_WITH_PKCE, KINDE_SCOPE } from '$env/static/private'; +import { + KINDE_ISSUER_URL, + KINDE_CLIENT_ID, + KINDE_CLIENT_SECRET, + KINDE_REDIRECT_URL, + KINDE_POST_LOGIN_REDIRECT_URL, + KINDE_POST_LOGOUT_REDIRECT_URL, + KINDE_AUTH_WITH_PKCE, + KINDE_SCOPE, + KINDE_DEBUG +} from '$env/static/private';

31-34: Consolidate dependency installation
Instead of two separatenpm installcommands, you can combine them to reduce friction:npm install @kinde-oss/kinde-auth-sveltekit @sveltejs/adapter-cloudflare -D
80-82: Improve error visibility in the storage adapter
Currently,createKindeStorageand its methods swallow errors and returnnull/false, which can make debugging difficult. Consider logging the caught error or rethrowing so failures are visible during development:- if (!AUTH_STORAGE) { - return null; - } + if (!AUTH_STORAGE) { + console.error('AUTH_STORAGE binding missing'); + throw new Error('KV namespace binding AUTH_STORAGE is not configured.'); + } ... - } catch (error) { - return false; - } + } catch (error) { + console.error('KV put error:', error); + throw error; + }Also applies to: 94-96, 111-113, 121-123
461-464: Leverage SvelteKit’sevent.cookiesAPI
Manually parsingevent.request.headers.get('cookie')is error‐prone. Prefer:const sessionId = event.cookies.get('kinde_session');And to clear:
event.cookies.delete('kinde_session', { path: '/', secure: true, sameSite: 'Lax' });This improves readability and correctness.
Also applies to: 515-518, 615-618
501-502: Remove unusedkindeAuthClientimport
You importkindeAuthClientbut never use it in+layout.server.ts. Either use the client for session loading or remove this line to avoid confusion.
603-646: Extract common cookie and token logic into helpers
The dashboard load logic duplicates cookie parsing andgetUserIdFromToken. Consider moving these to shared utilities ($lib/session.ts) and reusing them across both the layout and dashboard handlers to DRY up the code.

445-467:⚠️ Potential issueMissing Secure flag on cookie clear
When clearing thekinde_sessioncookie, you should include theSecureattribute to match the setter and ensure the cookie is invalidated over HTTPS:- 'Set-Cookie': 'kinde_session=; Path=/; HttpOnly; SameSite=Lax; Max-Age=0' + 'Set-Cookie': 'kinde_session=; Path=/; HttpOnly; Secure; SameSite=Lax; Max-Age=0'This is critical to avoid stale cookies.
🧹 Nitpick comments (10)
src/content/docs/integrate/third-party-tools/kinde-sveltekit-with-cloudflare.mdx (10)
1-5: Frontmatter formatting
Consider aligning the frontmatter with the MDX style guide. For example, ifpage_idis auto-generated (and not referenced elsewhere), you can remove it or add a comment explaining its use so readers understand why it’s present.
31-34: Combine installation commands
You can streamline the setup by installing both packages in one step, e.g.:npm install @kinde-oss/kinde-auth-sveltekit -D @sveltejs/adapter-cloudflareThis reduces friction for readers following the guide.
85-94: Log storage errors for debugging
Silently returningfalseinsetStatecan obscure KV failures. Consider logging the exception before returning:} catch (error) { - return false; + console.error('KV setState error:', error); + return false; }This will help users triage storage issues.
99-110: Surface KV retrieval errors
Similarly, suppressing errors ingetStateby returningnullhides root causes. Add logging for the catch block:} catch (error) { - return null; + console.error('KV getState error:', error); + return null; }This improves observability in production.
157-158: Cleanup environment imports
You’ve definedKINDE_DEBUGinwrangler.tomlbut it’s not imported or used here. Either removeKINDE_DEBUGfrom the configuration or import and guard your logs against it (e.g., wrapconsole.error/console.debugcalls).
169-178: Robust endpoint detection
url.pathname.split('/').pop()can return an empty string if the path ends with a slash. Consider trimming trailing slashes first:const path = url.pathname.replace(/\/$/, '').split('/').pop() || '';This ensures you always extract the correct segment.
275-377: Scope debug/error keys per user
You’re storing callback errors under generic keys ('last_error','token_error'), which may collide across concurrent flows. Namespace these entries (e.g.,error:state:${state}or using the session ID) to isolate error data per user.
379-442: Simplify PKCE branch
Since you only store a truecodeVerifierwhen PKCE is enabled, the extra!== 'true'check is no longer needed. You can streamline to:- if (USE_PKCE && codeVerifier && codeVerifier !== 'true') { - params.append('code_verifier', codeVerifier); - params.append('client_secret', SECRET); - } else { - params.append('client_secret', SECRET); - } + params.append('client_secret', SECRET); + if (USE_PKCE && codeVerifier) { + params.append('code_verifier', codeVerifier); + }This reduces conditional complexity.
501-504: Use SvelteKit's cookie API
Rather than parsingevent.request.headers, leverage SvelteKit’s built-in cookie helpers:const sessionId = event.cookies.get('kinde_session');This simplifies the code and handles encoding correctly.
589-632: Route protection example
The dashboard load function clearly illustrates guarding routes. To avoid duplicate logic, consider exporting and reusing thegetUserIdFromTokenhelper from your callback code rather than redefining it here.

137-143: Integrate session hooks with storage
The conditional spread ofstorageintosessionHooksis concise and correctly bypasses KV when unbound. This cleanly wires Cloudflare KV into the Kinde session lifecycle.
200-205: Secure randomness for OAuth state
Great use ofcrypto.getRandomValuesfor generating the state parameter—this addresses the cryptographic security concern and was an essential fix.
208-219: PKCE helper functions
Thesha256andbase64URLEncodeutilities correctly implement the PKCE code challenge. Their concise, promise-based design is ideal for Cloudflare’s environment.
221-272: Login flow implementation
The login handler cleanly orchestrates state, redirect, optional PKCE setup, and redirects to Kinde. Parameter extraction was moved into the correct order—this is well structured and readable.
469-480: Graceful error serialization
ThesafeStringifyhelper elegantly handles bothErrorobjects and unstringifiable payloads, ensuring robust debugging output.
556-582: Token refresh flow
The refresh logic correctly handles HTTP errors and JSON parsing, storing refreshed tokens back to KV. This aligns neatly with OAuth best practices.

8-11: Rephrase the note for clarity.
Consider updating “more complex than ideal” to something like “more complex than desired” to make the tone smoother.
13-18: Specify Node.js and npm versions in prerequisites.
Add a note about required Node.js (e.g., v16+) and npm/yarn versions to ensure compatibility with SvelteKit and Wrangler.
44-65: Updatecompatibility_dateto the current date.
The example uses"2023-06-28", which may be outdated. Suggest replacing with"<YYYY-MM-DD>"or documenting that this value should match the latest Cloudflare runtime date.
75-130: Log errors in KV adapter catch blocks for better observability.
Currently, failures insetState,getState, anddeleteStateare swallowed (returningfalseornull). Consider loggingerror.messageinside eachcatchto aid debugging of KV operations.
157-169: Polish import formatting and include debug flag.
- Add a missing space after the comma in
KINDE_AUTH_WITH_PKCE,KINDE_SCOPE.- Since
KINDE_DEBUGis defined inwrangler.toml, import it here to enable conditional logging later.
172-200: Use SvelteKit’s route parameters instead ofURL.pathname.
Leverageevent.params.kindeAuth(the dynamic[...kindeAuth]segment) for dispatching tologin,register, etc., to avoid brittle string parsing based on URL segments.
225-274: Check KV write results inhandleLogin.
storage.setStatereturns a boolean—consider verifying it'strueand handling error cases (e.g., return a 500 response) rather than assuming success.
397-401: Simplify PKCE check infetchTokens.
ThecodeVerifier !== 'true'condition is redundant sincecodeVerifieris always a string orundefined. You can streamline to:- if (USE_PKCE && codeVerifier && codeVerifier !== 'true') { + if (USE_PKCE && codeVerifier) {
490-493: Remove unusedkindeAuthClientimport.
kindeAuthClientisn’t referenced in this layout loader; you can delete it to clean up the code.
504-507: Leverageevent.cookies.get()for cookie retrieval.
Instead of manually parsingevent.request.headers, use SvelteKit’sevent.cookies.get('kinde_session')for more robust cookie handling.
592-597: Use built-in cookie API in dashboard route.
Similar to the layout loader, replace manual header parsing withevent.cookies.get('kinde_session')to simplify the protected-route sample.
626-634: Add TypeScript typing forgetUserIdFromToken.
Define theidTokenparameter as astringto improve clarity:function getUserIdFromToken(idToken: string): string | null { ... }

1-5: Frontmatter metadata looks good.
The page_id, title, and description are present and follow the project’s conventions.
19-28: Verify callback URL formatting.
The example uses/api/auth/kinde_callback; ensure that matches the route in your SvelteKit project (it should align with the[...kindeAuth]handler path).
31-34: Dependency installation is correct.
Installing@kinde-oss/kinde-auth-sveltekitand the Cloudflare adapter covers the essentials.
38-41: KV namespace setup instructions are clear.
The steps to create and copy the namespace ID in Cloudflare Pages are accurate.
67-70: Securing the client secret is well addressed.
MovingKINDE_CLIENT_SECRETinto a Wrangler secret aligns with best practices.
137-149: Hooks integration is correct.
UsingsessionHookswith a conditional storage binding ensures session support on Cloudflare Pages.

203-208: Duplicate of previous crypto‐secure randomness suggestion
generateRandomStringnow usescrypto.getRandomValues, fulfilling the earlier recommendation to avoidMath.random().
373-378:⚠️ Potential issueNamespace token exchange errors
You log and store JSONified errors under a fixed keytoken_error, which could collide across users or flows. It’s safer to namespace it similarly to state errors, e.g.:- await storage.setState('token_error', { … }); + await storage.setState(`token_error:${state}`, { … });
🧹 Nitpick comments (4)
src/content/docs/integrate/third-party-tools/kinde-sveltekit-with-cloudflare.mdx (4)
46-65: Suggest updatingcompatibility_dateto the current date
Keepingcompatibility_dateup-to-date helps ensure you benefit from the latest Cloudflare Pages runtime improvements. Consider bumping this to today’s date (e.g.,"2025-05-01").
75-130: Improve error visibility in the KV storage adapter
Currently,setState/getState/deleteStateswallow errors and returnfalse/nullwithout logging. In a production scenario, you’d want to at least logerror.message(or rethrow) to aid debugging. For example:setState: async (stateId: string, stateData: any) => { try { // ... await AUTH_STORAGE.put(key, value, { expirationTtl: 600 }); return true; } catch (error) { - return false; + console.error(`KV put failed for ${key}:`, error); + throw error; } },
383-445: Minor: simplify PKCE vs. non-PKCE branch
The checkcodeVerifier && codeVerifier !== 'true'is vestigial—your stored state is never the literal"true". You can consolidate to:- if (USE_PKCE && codeVerifier && codeVerifier !== 'true') { + if (USE_PKCE && codeVerifier) {
490-493: Remove unused import
kindeAuthClientis imported but never used in+layout.server.ts. Consider removing to keep the snippet focused:- import { kindeAuthClient } from '@kinde-oss/kinde-auth-sveltekit';

137-150: Hooks integration is correctly wired
ThesessionHookscall now properly passesstorageonly when available, preserving default behavior otherwise. This aligns with the package’s API and looks correct.
157-170: Environment imports look good
All required KINDE_* vars are pulled from$env/static/private, andKINDE_DEBUGisn’t referenced in this example (debug logs have been removed), so you don’t need to import it here.
172-200: Approve GET handler routing logic
The switch onpathcorrectly delegates to the four endpoints (login,register,kinde_callback,logout) and falls back to a 404. Error handling for missing KV is appropriate.
211-215: SHA-256 helper implementation is correct
Thesha256function leveragescrypto.subtle.digestas expected for PKCE, with proper encoding.
217-222: Base64 URL‐encode helper is accurate
Yourbase64URLEncodecorrectly replaces URL-unsafe characters and trims padding.
225-274: Login handler properly scopes state and redirect
You generate a cryptographically securestate, conditionally store the PKCE verifier, and namespace both verifier and redirect keys. The OAuth URL construction is clear and correct.
297-308: State validation and error scoping look good
Invalid state flows now log the error and store a namespacederror:${state}entry, avoiding cross-session collisions.
318-321: Cleanup of state and redirect keys is correct
Deleting both the PKCE verifier and redirect entries ensures no stale data remains in KV.
323-336: Token storage under session‐scoped key is solid
Storing the full token set withtimestampand TTL fields undersession:${sessionId}:tokensis precisely what you need for later validation and refresh.
340-352: User ID extraction is handled safely
The ID token is parsed defensively with atry/catch, which prevents runtime crashes on malformed tokens.
359-367: Session cookie includesSecureflag
YourSet-Cookieheader now hasHttpOnly; Secure; SameSite=Lax; Max-Age=2592000, which aligns with best practices.
448-470: Logout handler correctly clears session
Deleting thesession:${sessionId}:tokenskey and clearing the cookie withSecure; SameSite=Laxis spot-on.
473-483:safeStringifycovers edge cases
This helper gracefully handles errors and unstringifiable objects. It’s concise and effective.
495-557: Layout load function and token refresh logic are correct
The session lookup, expiration check with buffer, and refresh flow cover all necessary cases. Error handling safely falls back to unauthenticated.
592-635: Dashboard route protection is solid
You correctly redirect unauthenticated users and extractuserIdfrom the ID token. In a Cloudflare Pages environment,atobis available, so this will run smoothly.

31-34: Combine installation commands for brevity
You can merge the twonpm installcommands into one for conciseness:```bash -npm install @kinde-oss/kinde-auth-sveltekit -npm install -D @sveltejs/adapter-cloudflare +npm install @kinde-oss/kinde-auth-sveltekit +npm install --save-dev @sveltejs/adapter-cloudflare--- `67-70`: **Consolidate secret instructions under the main Wrangler setup** Rather than a separate "4.1" subheading, consider folding the `wrangler secret put` guidance into Step 4 to keep numbering flat and clear. --- `75-130`: **Improve error handling in the storage adapter** Currently errors are swallowed (returning `false`/`null`) without logging, which can make debugging difficult. Consider logging the error message before returning, or throwing an explicit error to bubble up issues: ```diff setState: async (stateId: string, stateData: any) => { try { … } catch (error) { - return false; + console.error(`createKindeStorage.setState error for ${stateId}:`, error); + return false; } },
154-200: Format imports and spacing for readability
Split the long import onto multiple lines and ensure spaces after commas:-import { KINDE_ISSUER_URL, KINDE_CLIENT_ID, KINDE_CLIENT_SECRET, KINDE_REDIRECT_URL, KINDE_POST_LOGIN_REDIRECT_URL, KINDE_POST_LOGOUT_REDIRECT_URL, KINDE_AUTH_WITH_PKCE,KINDE_SCOPE } from '$env/static/private'; +import { + KINDE_ISSUER_URL, + KINDE_CLIENT_ID, + KINDE_CLIENT_SECRET, + KINDE_REDIRECT_URL, + KINDE_POST_LOGIN_REDIRECT_URL, + KINDE_POST_LOGOUT_REDIRECT_URL, + KINDE_AUTH_WITH_PKCE, + KINDE_SCOPE +} from '$env/static/private';
224-275: Add error handling around storage operations
Wrap calls tostorage.setStateintry/catchor at least check the boolean return value to ensure state or redirect is stored successfully before proceeding.
383-444: Simplify PKCE verification logic
The checkcodeVerifier !== 'true'is unnecessary—codeVerifieris either a generated string orundefined. Simplify to:- if (USE_PKCE && codeVerifier && codeVerifier !== 'true') { + if (USE_PKCE && codeVerifier) {
490-492: Remove unusedkindeAuthClientimport
kindeAuthClientis imported but never used. Consider removing this line to prevent confusion:- import { kindeAuthClient } from '@kinde-oss/kinde-auth-sveltekit';
592-635: Type and reuse thegetUserIdFromTokenhelper
Define the function signature explicitly and consider sharing it between the callback and dashboard logic to avoid duplication. For example:- function getUserIdFromToken(idToken) { + function getUserIdFromToken(idToken: string): string | null {

51-54: Standardize Step 4 heading style
The heading uses “Set Up” instead of “Set up”. This duplicates an earlier suggestion.
286-389:⚠️ Potential issueNamespace token_error storage to avoid collisions
Storing errors under a global key risks overlapping diagnostics across flows. Use a state-specific key likeerror:${state}.- await storage.setState('token_error', { + await storage.setState(`error:${state}`, { time: new Date().toISOString(), error: safeStringify(error) });
🧹 Nitpick comments (5)
src/content/docs/integrate/third-party-tools/kinde-sveltekit-with-cloudflare.mdx (5)
28-37: Use sentence case for step headings
The step title uses “Set Up” (title case). To align with Sentence case guidelines, change to “Set up”.- ## Step 1: Set Up a Kinde application + ## Step 1: Set up a Kinde application
45-50: Sentence case for Storage step
Change “Configure Cloudflare KV Storage” to “Configure Cloudflare KV storage” to match Sentence case conventions.- ## Step 3: Configure Cloudflare KV Storage + ## Step 3: Configure Cloudflare KV storage
56-74: Consider updating compatibility_date
Thecompatibility_date = "2023-06-28"is outdated for a 2025 deployment. Updating this to a more recent date ensures alignment with Cloudflare Pages’ current environment.- compatibility_date = "2023-06-28" + compatibility_date = "2025-05-01" # or the current date of merge
84-139: Enhance storage adapter error visibility
Silentreturn false/nullin catch blocks can obscure underlying issues. Logging the error message will aid debugging.} catch (error) { - return false; + console.error('KV setState error:', error); + return false; } ... } catch (error) { - return null; + console.error('KV getState error:', error); + return null; } ... } catch (error) { - return false; + console.error('KV deleteState error:', error); + return false; }
392-450: Clean up unnecessarycodeVerifiercheck
Since you only store a verifier when PKCE is enabled, the&& codeVerifier !== 'true'guard is redundant. Remove it for clarity.- if (USE_PKCE && codeVerifier && codeVerifier !== 'true') { + if (USE_PKCE && codeVerifier) {

1-10: Front matter is correctly formatted
The YAML front matter matches the project’s required keys and indentation style.
16-20: Admonition formatting looks good
The<Aside type="warning">block has the proper blank lines before and after content, matching the project’s style.
22-27: Checklist section is clear
The “## What you need” heading and its bullet list correctly outline prerequisites.
40-43: Installation instructions are accurate
The npm install commands are clear and correct for both production and dev dependencies.
143-159: Hook integration is correct
Thehandleimplementation ties Kinde session hooks to the custom storage adapter as intended.
165-209: Auth route dispatcher looks solid
The switch on the trailing path segment and early storage availability check handle the OAuth flows as expected.
211-217: Secure random generation is implemented properly
ThegenerateRandomStringfunction usescrypto.getRandomValuesand a suitable character set.
220-230: PKCE helper functions are well-defined
Thesha256andbase64URLEncodeimplementations follow the PKCE spec and use the Web Crypto API.
234-284: Login handler logic is clear and robust
State, PKCE, and redirect parameter handling appear correct, with clean separation of concerns.
456-479: Logout handler properly clears session
The session cookie is securely cleared with theSecureflag, and the redirect to Kinde’s logout endpoint is correct.
481-492: Error stringification helper is effective
ThesafeStringifyfunction cleanly handles both Error instances and arbitrary objects.
499-567: Layout load implements token refresh logic correctly
Your logic for reading the session cookie, checking expiry, and refreshing tokens is sound and includes a safety buffer.
569-593: Refresh token flow is well-handled
The refresh request parameters, error handling, and response parsing cover expected failure modes.
601-644: Protected route enforcement is correct
The dashboard loader enforces authentication, redirects unauthenticated users, and extracts the user ID safely.

You’re writing errors under the fixed keytoken_error, which can overwrite errors from concurrent sessions. Prefix it with the flow’s state or session ID—e.g.,error:${state}—to isolate per-flow diagnostics.- await storage.setState('token_error', { + await storage.setState(`error:${state}`, {

1-4: Capitalize "SvelteKit" correctly in the title
The front-matter title uses "Sveltekit" (lowercase K). For consistency with the product name, update it to "SvelteKit".--- title: Kinde with Sveltekit on Cloudflare Pages +++ title: Kinde with SvelteKit on Cloudflare Pages
28-28: Ensure consistent sentence-case in step headings
The first step heading uses "Set Up" (title case) while others use sentence case. Change to "Set up a Kinde application" to match style.- ## Step 1: Set Up a Kinde application + ## Step 1: Set up a Kinde application
52-52: Ensure consistent sentence-case in step headings
Similarly, update "Set Up Wrangler configuration" to "Set up Wrangler configuration" for consistency.- ## Step 4: Set Up Wrangler configuration + ## Step 4: Set up Wrangler configuration
76-79: Avoid using a sub-heading for a single note
The line "### Add KINDE_CLIENT_SECRET separately…" is rendered as a tertiary heading. Per style, convert this into a regular paragraph or wrap in an<Aside>block so it doesn’t interrupt the step flow.
56-63: Refresh compatibility_date to latest Cloudflare environment
The example uses"2023-06-28". It’s best practice to bump this to the current date (e.g.,"2025-05-01") so readers know it’s tested against the latest Pages runtime.- compatibility_date = "2023-06-28" + compatibility_date = "2025-05-01"
40-43: Combine installation commands for brevity
You can merge the twonpm installcommands into one to streamline the instructions.npm install @kinde-oss/kinde-auth-sveltekit @sveltejs/adapter-cloudflare --save-dev
87-94: Handle missing KV binding more explicitly
CurrentlycreateKindeStoragereturnsnullifAUTH_STORAGEisn’t bound—this may lead to silent failures downstream. Consider throwing an error or logging a warning so implementers know their binding is misconfigured.- if (!AUTH_STORAGE) { - return null; - } + if (!AUTH_STORAGE) { + console.error('AUTH_STORAGE namespace is not bound in wrangler.toml'); + throw new Error('Missing KV binding: AUTH_STORAGE'); + }
183-185: Use SvelteKit’s route params instead of manual URL splitting
Parsing the endpoint byurl.pathname.split('/').pop()can break if the path changes. Since this is in a[...kindeAuth]route, you can access the segment viaevent.params.kindeAuth.- const path = url.pathname.split('/').pop() || ''; + const path = event.params.kindeAuth;
459-462: Use SvelteKit’s cookie API in logout handler
Instead of parsingevent.request.headers.get('cookie'), leverageevent.cookies.get('kinde_session')andevent.cookies.delete('kinde_session')for clarity and maintainability.- const cookies = event.request.headers.get('cookie') || ''; - const sessionMatch = cookies.match(/kinde_session=([^;]+)/); - const sessionId = sessionMatch ? sessionMatch[1] : null; + const sessionId = event.cookies.get('kinde_session'); + if (sessionId) { + event.cookies.delete('kinde_session', { path: '/', httpOnly: true, sameSite: 'Lax', secure: true }); + }

154-156: Global storage assignment can race across concurrent requests
setActiveStoragestores the KV instance in a module-level singleton. On Cloudflare Workers, multiple requests share the same isolate, so a second request can overwrite the storage while the first is still executing. Consider returning the storage object frominitializeKindeAuthand passing it explicitly tojs-utilsfunctions that allow it, or open an issue to add per-request context support in@kinde/js-utils.

24-29: Minor copy-editing for prerequisites list
The first list item reads “Pages and KV access”. For subject/verb agreement and clarity consider:- A Cloudflare account with Pages and KV access + A Cloudflare account with access to Cloudflare Pages and KVTiny polish, but it prevents the “KV access” grammar warning flagged by tooling.
39-42: Add missing article in step description
“In Cloudflare dashboard” should include the article “the” to read naturally:- In Cloudflare dashboard, go to **Workers & Pages > KV** + In the Cloudflare dashboard, go to **Workers & Pages > KV**
48-52: Updatecompatibility_dateto avoid unexpected runtime differences
compatibility_date = "2023-06-28"is quite old. New contributors copying this file may hit subtle runtime differences (e.g. URL pattern handling) because Workers activates backwards-compat shims for that date. Unless you rely on legacy behaviour, bump this to today’s date or add a note explaining the freeze.

🛠️ Refactor suggestion
Replace arbitrary 2 s sleep with deterministic wait
Using setTimeout(2000) to “wait for async token storage” is brittle: slow writes may still race; fast writes waste 2 s. Prefer awaiting the promise returned by exchangeAuthCode (it already resolves after storage) or expose a flush() helper from your storage adapter.
- await new Promise(resolve => setTimeout(resolve, 2000));
+ // Storage write completed inside exchangeAuthCode; no need to delay.If @kinde/js-utils truly emits the window error before the promise settles, consider opening an issue upstream instead of hard-coding a delay.

around lines 266 to 270, replace the arbitrary 2-second setTimeout delay used to
wait for async token storage with a deterministic wait by awaiting the promise
returned by the async token storage function (such as exchangeAuthCode) or by
calling a flush() method from the storage adapter if available. This ensures the
code only proceeds after token storage completes, avoiding brittle fixed delays.

Logout endpoint doesn’t clear local session data
Redirecting to Kinde’s /logout without first deleting session cookies or KV tokens means the user can still appear authenticated until the IdP callback returns. Clear both stores before redirecting:
async function handleLogout(config: ReturnType<typeof getConfig>) {
+ // Clear local auth
+ await setActiveStorage().removeSession(); // pseudo-code – adjust to actual js-utils API
+
const logoutUrl = new URL('/logout', config.issuerURL);
logoutUrl.searchParams.append('redirect', config.postLogoutRedirectURL);
return redirect(302, logoutUrl.toString());
}This ensures instant sign-out and avoids token reuse in subsequent requests.

around lines 278 to 283, the logout function redirects to the logout URL without
clearing local session data, which can cause the user to appear authenticated
temporarily. Modify the function to clear session cookies and any KV tokens or
local storage related to authentication before performing the redirect. This
ensures immediate sign-out and prevents token reuse in subsequent requests.

🛠️ Refactor suggestion
Avoid re-registering global storage on every request
setActiveStorage and setInsecureStorage mutate singleton state inside @kinde/js-utils. Calling them on every request can introduce race conditions under high concurrency and unnecessary object churn.
Suggested pattern:
-let tokenStorage: KvStorage | undefined;
-let tempStorage: CookieStorage | undefined;
-
-export function initializeKindeAuth(event: RequestEvent): boolean {
- …
- // KV storage for long-term token storage
- tokenStorage = tokenStorage ?? new KvStorage(AUTH_STORAGE, { defaultTtl: 2592000 });
- // Cookie storage for temporary OAuth data
- tempStorage = new CookieStorage(event);
- setActiveStorage(tokenStorage);
- setInsecureStorage(tempStorage);
- …
-}
+const globalTokenStorage = new WeakMap<object, KvStorage>();
+
+export function initializeKindeAuth(event: RequestEvent): boolean {
+ …
+ if (!globalTokenStorage.has(AUTH_STORAGE)) {
+ globalTokenStorage.set(AUTH_STORAGE, new KvStorage(AUTH_STORAGE, { defaultTtl: 2592000 }));
+ setActiveStorage(globalTokenStorage.get(AUTH_STORAGE)!);
+ }
+ setInsecureStorage(new CookieStorage(event)); // per-request, fine
+ …
+}That ensures the heavy KV instance is initialised once per process while keeping per-request cookie storage.

around lines 138 to 157, the calls to setActiveStorage and setInsecureStorage
are made on every request, which can cause race conditions and unnecessary
object creation. Refactor the code to initialize the KV storage and call
setActiveStorage once per process outside the request handler, while keeping the
CookieStorage and setInsecureStorage calls inside the request handler to
maintain per-request state. This avoids re-registering global storage on every
request and improves concurrency safety.
This PR adds documentation for integrating Kinde authentication with SvelteKit on Cloudflare Pages.
I've created this guide based on my implementation experience, and while it's functional, I recognize that it's more complex than ideal. The current solution requires more code than I'd like, especially in the server handler, due to the unique constraints of Cloudflare's serverless environment and how it interacts with OAuth flows.
I would greatly appreciate feedback on:
I'm very open to suggestions on how to make this guide more concise and maintainable.
