🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secret safely. Learn here the best practices.
3. Revoke and rotate this secret.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.

Walkthrough

Introduces runtime secrets into deployment management, adds environment validation and request validation to deploy API, enhances domain analytics, tightens auth and downstream calls in success API, updates CORS type-casting, adjusts tRPC context typing, renames a chat token limit param, tweaks domains handler params, and refines service worker caching headers.

Changes

Cohort / File(s)	Summary
CORS header typing api/create-checkout-session.ts	Casts requestOrigin to string when setting Access-Control-Allow-Origin in OPTIONS and main CORS branches; no behavioral change.
Deployment secrets + handler flow api/deploy.ts, lib/deployment/manager.ts	Adds runtime secrets plumbing (tokens/team IDs) to deployment manager and services; introduces environment validation, request validation, list action, enhanced logging/analytics; updates manager to consume secrets and enriches domain analytics.
Domains handler param rename api/domains.ts	Renames unused first parameter to _req in setup/verify handlers; logic unchanged.
tRPC context typing api/hono-trpc.ts	createContext callback now accepts (opts, c) and returns context cast to Record<string, unknown>.
Secret chat param rename api/secret-chat.ts	Switches maxTokens to maxCompletionTokens; uses object property shorthand for google provider init.
Success auth gating and fallback api/success.ts	Requires Authorization header and verifyAuth; forwards header to get-subscription; on non-OK, returns neutral plan/status; logs auth context.
SW runtime caching filter vite.config.ts	Adds cacheableResponse.headers filter to avoid caching responses with Cache-Control: no-store for health endpoints.

Poem

A hare taps keys with twitchy delight,
Secrets burrowed, tokens tucked tight.
Domains aligned, success now neat—
Cache the carrots, skip no-store treats.
CORS behaves, the chat’s succinct;
Deploys hop forth—ship, and wink. 🥕🐇

167-199: Security regression: “non-sensitive” config type includes access tokens; conflicts with comments and ZapdevDeploymentSecrets

The comment at Line 167 states “non-sensitive settings”, and the Netlify/Vercel sections above explicitly say accessToken moved to ZapdevDeploymentSecrets. However, ZapdevDeploymentConfig still embeds accessToken for both providers. This invites accidental serialization/logging of secrets and contradicts the intended separation.

Proposed fix: remove tokens from ZapdevDeploymentConfig and keep them solely in ZapdevDeploymentSecrets. Optionally mark previous fields as deprecated to ease migration.

-// Configuration for zapdev deployment service (non-sensitive settings)
+// Configuration for zapdev deployment service (non-sensitive settings)
 export interface ZapdevDeploymentConfig {
   // Include sensitive deployment configuration
-  netlify: {
-    accessToken: string;
-    teamId?: string;
-  };
-  vercel: {
-    accessToken: string;
-    teamId?: string;

+    /** @deprecated Access tokens must live in ZapdevDeploymentSecrets */

   baseDomain: string; // "zapdev.link"
 
   // Reference to secure credential storage
   // Secrets must be retrieved from ZapdevDeploymentSecrets at runtime
   secretsRef?: string; // Optional reference to secret storage key

Follow-up: ensure api/deploy.ts and lib/deployment/manager.ts exclusively source tokens from ZapdevDeploymentSecrets. I can help generate a small codemod to catch lingering config.accessToken usages if useful.

95-105: Script-tag regex weakened; restore tolerant close-tag to avoid evasion

Changing from a tolerant </script...> to a strict </script> can miss variants like </script > and some malformed-but-recognized closers. Recommend using a boundary + optional whitespace pattern.

-    /<script[^>]*>[\s\S]*?<\/script>/is,
+    /<script\b[^>]*>[\s\S]*?<\/script\s*>/is,

Optional hardening (nice-to-have):

• Add /<style\b[^>]*>[\s\S]*?<\/style\s*>/is if style injection is a concern.
• Add stricter SVG handling if needed (e.g., /<svg\b[^>]*>[\s\S]*?<\/svg\s*>/is), though your on\w+= and data:svg checks already catch many cases.

I can add unit tests covering </script >, mixed-case tags, and nested/script-like strings if you’d like.

23-42: Broken flow: handlePrivacyComplete is never called, so the Clerk signup modal may never open

The only place that calls openSignUp is inside handlePrivacyComplete, but that function isn’t invoked or passed down to PrivacyConsentStep. If showConsent is true, users see the consent UI and then get stuck; if showConsent is false (already consented), the component returns null and never opens the modal.

Fix by reacting to consent state and opening the modal once consent exists, and also when consent isn’t required. Guard to avoid double-open.

49-112: Existing sanitization functions bypass new validation logic

The original sanitizeText, sanitizeCode, sanitizeOutput, and createSanitizedHtml functions don't use the new validation logic with MALICIOUS_PATTERNS checking. This creates an inconsistent security posture.

Consider updating the existing functions to use the new validation:

 export function sanitizeText(text: string | null | undefined, fallback = ''): string {
   if (text == null) {
     return fallback;
   }
   
   if (typeof text !== 'string') {
     return escapeHtml(String(text));
   }
   
+  // Check for malicious patterns
+  const validation = validateInput(text);
+  if (!validation.isValid) {

+    return fallback;
+  }
+  
   return escapeHtml(text);

414-427: Fix path-type import inconsistency that can break NodeNext builds

Two inline type imports reference different module specifiers: import('./types.js') (Line 414) vs import('./types') (Line 425). With "moduleResolution": "NodeNext", the latter can fail at build/runtime.

121-123: Eager environment validation at module load will take the entire endpoint down

Calling validateEnvironmentVariables() at import-time throws if tokens are missing, preventing even OPTIONS/GET error responses. This is a hard failure on Vercel.

Move validation into getDeploymentManager() or the request path. Example:

-// Validate environment variables
-const validatedEnv = validateEnvironmentVariables();
+// Lazy-init validated env
+let validatedEnv: ReturnType<typeof validateEnvironmentVariables> | null = null;

And inside getDeploymentManager():

-  if (!deploymentManager) {
+  if (!deploymentManager) {
+    if (!validatedEnv) validatedEnv = validateEnvironmentVariables();
     const secrets = {
-      netlify: { accessToken: validatedEnv.netlifyAccessToken, teamId: process.env.NETLIFY_TEAM_ID },
-      vercel:  { accessToken: validatedEnv.vercelAccessToken,  teamId: process.env.VERCEL_TEAM_ID  },

101-112: Over-strict: requiring both Netlify and Vercel tokens to be set

124-135: Do not put access tokens into the config object; keep them only in the secrets object

ZapdevDeploymentConfigWithSecrets embeds tokens into deploymentConfig. Configs are more likely to be serialized, logged, or returned by mistake. You already pass a proper secrets object to the manager—duplicate storage increases leakage risk.

Remove token fields from the config entirely and drop the ZapdevDeploymentConfigWithSecrets type:

-// Extended configuration interface that includes runtime secrets
-interface ZapdevDeploymentConfigWithSecrets extends ZapdevDeploymentConfig {

🧹 Nitpick comments (48)

.claude/settings.local.json (3)

96-96: 30s build timeout is likely too short; consider relaxing or wildcarding the command.

Bun/Next/Vite builds can exceed 30 seconds under CI load. An overly strict, exact-match allow entry may cause flakiness or future edits to be blocked.

Apply one of the following:

-      "Bash(timeout 30 bun run build)",
+      "Bash(timeout 180 bun run build)",

Or make the permission resilient to minor flag changes:

-      "Bash(timeout 30 bun run build)",
+      "Bash(timeout * bun run build:*)",

Please confirm which pattern the permissions parser supports (exact match vs. globbing within parentheses and after), and choose accordingly.

---

97-97: Allowing ripgrep is useful; scope it to safe defaults to reduce noisy output and accidental secret exposure.

Unconstrained rg:* can traverse large trees and print entire files (including .env-like files) if invoked carelessly. Since grep:* already exists, adding rg is consistent, but we can tame defaults.

Consider constraining to typical, read-only search flags and excluding common heavy/secret paths:

-      "Bash(rg:*)"
+      "Bash(rg -n -C3 --hidden --max-columns 200 --glob '!**/node_modules/**' --glob '!**/.git/**' --glob '!.env*':*)"

If the permissions grammar doesn’t support embedded flags or globs, keep Bash(rg:*) and add a deny rule for .env* and VCS dirs, or rely on repo conventions. Please confirm the grammar and we can adjust.

---

1-3: Sanity check: is tracking a local Claude settings file intentional?

File name suggests a local, tool-specific config. If that’s by design for this repo, all good; otherwise consider ignoring .claude/*.local.json via VCS to avoid leaking tool policy changes into PRs.

api/success.ts (6)

19-24: Auth header normalization is correct; consider centralizing to avoid duplication across API routes.

Good handling of Node’s IncomingHttpHeaders union (string | string[] | undefined). To keep this consistent across routes, consider a tiny shared helper like getAuthorizationHeader(req) in api/_utils/auth.ts and reuse it here and elsewhere.

---

37-41: Harden the internal fetch: add Accept header, timeout, and robust URL join.

Small hardening to make this call more resilient and type-friendly:

• Add Accept: application/json to document expectations.
• Add a fetch timeout to avoid hanging executions (especially relevant on serverless).
• Build the URL via new URL() to avoid accidental double slashes.

Apply:

-    const baseUrl = process.env.PUBLIC_ORIGIN || 'http://localhost:3000';
-    const response = await fetch(`${baseUrl}/api/get-subscription`, {
-      headers: { Authorization: authorization },
-    });
+    const baseUrl = process.env.PUBLIC_ORIGIN || 'http://localhost:3000';
+    const url = new URL('/api/get-subscription', baseUrl).toString();
+    const controller = new AbortController();
+    const timeout = setTimeout(() => controller.abort(), 10_000); // 10s
+    const response = await fetch(url, {
+      method: 'GET',
+      headers: {
+        Authorization: authorization,
+        Accept: 'application/json',
+      },
+      signal: controller.signal,
+    });
+    clearTimeout(timeout);

---

42-56: Confirm intent: returning 200 on subscription fetch failure may mask issues; at least signal fallback in the payload.

If this is deliberate to keep UX smooth, consider explicit signaling so the client/UI can reflect the degraded state and optionally trigger a retry.

Apply:

-      // Return a basic success response even if subscription fetch fails
+      // Return a basic success response even if subscription fetch fails
+      // Signal fallback so the client can react (e.g., retry, banner)
       return res.status(200).json({
         success: true,
         message: 'Success endpoint called, subscription sync may be delayed',
         planId: 'free',
-        status: 'none'
+        status: 'none',
+        fallback: true
       });

Optionally, treat network errors in the catch block the same way (see a suggested change on Lines 67-78).

Is the 200-on-failure behavior a product decision? If not, a 502 with a client-visible retry path might be preferable.

---

58-65: Parse the JSON defensively and narrow types before use.

response.json() returns unknown at runtime. Guard the shape to avoid surprises and align with strict typing. No external deps required.

Apply:

-    const subscription = await response.json();
-    
-    return res.status(200).json({
-      success: true,
-      message: 'Subscription status synced successfully',
-      planId: subscription.planId || 'free',
-      status: subscription.status || 'none'
-    });
+    const raw = (await response.json()) as unknown;
+    const { planId, status } = isSubscriptionPayload(raw) ? raw : {};
+    return res.status(200).json({
+      success: true,
+      message: 'Subscription status synced successfully',
+      planId: typeof planId === 'string' && planId ? planId : 'free',
+      status: typeof status === 'string' && status ? status : 'none',
+    });

Add this small type guard (place near the bottom of the file or in a shared utils module):

function isSubscriptionPayload(x: unknown): x is { planId?: string; status?: string } {
  return !!x && typeof x === 'object' && (
    'planId' in x || 'status' in x
  );
}

67-78: Network errors are handled as 500; consider aligning with the non-OK branch and return a marked fallback.

If the intent is “best-effort” sync, match the behavior of the non-OK flow to reduce variance in client handling. You still log the sanitized error for observability.

Apply:

   } catch (error) {
     logSanitizedError('Success endpoint error', error instanceof Error ? error : new Error(String(error)), {
       method: req.method,
       url: req.url,
       hasAuth: !!authorization
     });
-
-    return res.status(500).json({
-      error: 'Internal server error',
-      message: 'Failed to process success callback'
-    });
+    // Degraded mode: return a marked fallback like the non-OK branch above
+    return res.status(200).json({
+      success: true,
+      message: 'Success endpoint processed with degraded subscription sync',
+      planId: 'free',
+      status: 'none',
+      fallback: true
+    });
   }

---

5-5: Add an explicit return type to the route handler.

To satisfy “explicit return types for public APIs” without refactoring the early return res.status().json(...) lines, annotate as Promise<VercelResponse | void>.

Apply:

-export default async function handler(req: VercelRequest, res: VercelResponse) {
+export default async function handler(req: VercelRequest, res: VercelResponse): Promise<VercelResponse | void> {

api/secret-chat.ts (2)

27-27: Potential type compatibility issue with Headers constructor

The casting of req.headers to Record<string, string> may cause runtime issues since Vercel request headers can contain string | string[] values. The Headers constructor expects string | string[] for values, but the cast forces all values to be strings only.

Consider removing the type assertion to allow proper header handling:

-    const authResult = await verifyAuth({ headers: new Headers(req.headers as Record<string, string>) });
+    const authResult = await verifyAuth({ headers: new Headers(req.headers) });

If the verifyAuth function specifically requires the current signature, consider updating it to handle the proper header types instead.

---

85-87: Consider optional chaining for usage properties

While the current null coalescing with || 0 works, using optional chaining would be more consistent with modern TypeScript patterns and clearer about the intent.

-        usage: {
-          promptTokens: usage?.inputTokens || 0,
-          completionTokens: usage?.outputTokens || 0,
-          totalTokens: usage?.totalTokens || 0,
-        },
+        usage: {
-          promptTokens: usage?.inputTokens ?? 0,
-          completionTokens: usage?.outputTokens ?? 0,
-          totalTokens: usage?.totalTokens ?? 0,
-        },

28-43: Optional: avoid trimming in sanitizeText or make it opt-in

Trimming may surprise users by removing intentional leading/trailing spaces. Consider an optional parameter to control trimming, defaulting to false in non-UI contexts.

-export const sanitizeText = (text: string): string => {
+export const sanitizeText = (text: string, opts: { trim?: boolean } = {}): string => {
   return text
     .replace(/[<>'"&]/g, (char) => {
       switch (char) {
         case '<': return '&lt;';
         case '>': return '&gt;';
         case "'": return '&#x27;';
         case '"': return '&quot;';
         case '&': return '&amp;';
         default: return char;
       }
     })
-    .trim();
+    [opts.trim === false ? 'toString' : 'trim']();
};

Call sites can then enable trimming where appropriate.

29-30: Dev UX: consider non-root user to avoid host permission issues when mounting volumes

Running as root in dev can cause file ownership friction on bind mounts. The Bun image typically includes a bun user.

 # Start the development server with hot reloading
-CMD ["bun", "run", "dev:api"]
+USER bun
+CMD ["bun", "run", "dev:api"]

If the image variant lacks the user, you can add one:

+RUN adduser -D -u 10001 appuser && chown -R appuser:appuser /app
+USER appuser

11-14: Lockfile name verified – bun.lock is correct

The repository contains bun.lock (no bun.lockb), so the Dockerfile.dev line remains valid.

• File affected: Dockerfile.dev (lines 11–14)
• No change needed for the lockfile name
• Optional improvement: ensure reproducible installs by pinning the lockfile during install

  RUN bun install --frozen-lockfile

api/create-checkout-session.ts (1)

24-24: Fix type assertions - requestOrigin is already validated

The type assertions requestOrigin as string are unnecessary and potentially unsafe. The isOriginAllowed helper already validates that requestOrigin exists before returning true, so when we reach these lines, requestOrigin is guaranteed to be a string.

Apply this diff to remove the unnecessary type assertions:

-      res.setHeader('Access-Control-Allow-Origin', requestOrigin as string);
+      res.setHeader('Access-Control-Allow-Origin', requestOrigin!);

-    res.setHeader('Access-Control-Allow-Origin', requestOrigin as string);
+    res.setHeader('Access-Control-Allow-Origin', requestOrigin!);

The non-null assertion ! is safer here since we know from the isOriginAllowed check that requestOrigin is defined.

62-107: Add a completion callback to PrivacyConsentStep (if supported) to advance the flow

If PrivacyConsentStep supports an onComplete/onAccept prop, pass a callback that flips step and triggers the signup. Otherwise, the useEffect approach in the earlier diff guarantees progress without needing a prop. If PrivacyConsentStep does expose a callback, wire it for clearer intent.

---

109-111: Avoid returning null; provide loading feedback while the modal opens

Per UI guidelines, show loading feedback during async transitions. Render a lightweight placeholder (skeleton or spinner) when not showing the consent step and before Clerk’s modal appears.

Apply this minimal placeholder:

-  // Once privacy consent is handled, Clerk modal will handle the rest
-  return null;
+  // Once privacy consent is handled, Clerk modal will handle the rest
+  return (
+    <div className="flex items-center justify-center py-12 text-sm text-muted-foreground">

25-51: Harden IntersectionObserver setup (SSR-safe + proper cleanup)

• If IntersectionObserver isn’t available (older browsers, some bots), the content will never render. Bail out by marking as loaded.
• Prefer observer.disconnect() in cleanup to ensure we drop all targets and GC cleanly.

Apply this diff:

   useEffect(() => {
-    const observer = new IntersectionObserver(
+    if (typeof window === 'undefined' || !('IntersectionObserver' in window)) {
+      setHasLoaded(true);
+      return;

       ([entry]) => {
         if (entry.isIntersecting && !hasLoaded) {
           setIsIntersecting(true);
           setHasLoaded(true);
           observer.unobserve(entry.target);
         }
       },
       {
         rootMargin,
         threshold,
       }
     );
 
     const currentRef = ref.current;
     if (currentRef) {
       observer.observe(currentRef);
     }
 
     return () => {

15-21: Nit: dns-prefetch targets should be origins, not full URLs

Most UA examples use href="//origin" or href="https://origin" without paths. Yours are fine, but consider normalizing and de-duplicating with preconnect (which you already do).

-const DNS_PREFETCH_DOMAINS = [
-  'https://fonts.googleapis.com',
-  'https://fonts.gstatic.com',
-  'https://api.groq.com',
-  'https://api.clerk.dev',

Additionally, you can skip dns-prefetch when using preconnect for the same origins to reduce tag noise.

12-13: Preloading Google Fonts stylesheet needs rel="preload" + onload swap to be effective

Preloading a stylesheet cross-origin without applying it yields limited benefit. If you intend to apply it, use the standard pattern or rely on your existing CSS imports and keep only preconnect.

Example pattern:

<link rel="preload" as="style" href="https://fonts.googleapis.com/css2?family=Inter:wght@400;600&display=swap" onload="this.onload=null;this.rel='stylesheet'">
<noscript><link rel="stylesheet" href="https://fonts.googleapis.com/css2?family=Inter:wght@400;600&display=swap"></noscript>

---

65-72: Use the PWA plugin’s registration helper instead of manual SW registration

Your project is already configured with vite-plugin-pwa in vite.config.ts (lines 51–56), which:

• Generates sw.js in production builds
• Injects a manifest into sw-custom.js in development
• Uses injectRegister: 'auto' and registerType: 'autoUpdate'

Manually calling navigator.serviceWorker.register('/sw.js') in src/components/ResourcePreloader.tsx always points at /sw.js, even in dev—resulting in 404s for sw-custom.js. Instead, let the plugin handle registration and updates via its virtual helper:

• Remove the manual block in ResourcePreloader.tsx (around lines 65–72)
• Add at the top of your app (e.g. in main.tsx):

import { registerSW } from 'virtual:pwa-register'

const updateSW = registerSW({
  immediate: true,
  onNeedRefresh()  { /* prompt user to reload */ },
  onOfflineReady() { /* show offline indicator */ },
})

This ensures the correct file is registered (whether sw.js or sw-custom.js), handles auto-updates, and keeps your registration logic in sync with your Vite PWA config.

4-9: Consider whether preloading favicon.svg is necessary

93-101: Preload both font weights you declare as critical

You embed 400 and 600 weights but only preload 400. Preloading both avoids FOIT when the bold variant first appears.

     const preloadLink = document.createElement('link');
     preloadLink.rel = 'preload';
     preloadLink.href = '/fonts/inter-v12-latin-regular.woff2';
     preloadLink.as = 'font';
     preloadLink.type = 'font/woff2';
     preloadLink.crossOrigin = 'anonymous';

24-31: Extract OptimizedFallback into its own reusable component

The OptimizedFallback definition is currently inlined within src/components/LazyComponents.tsx (lines 24–31) and duplicated across multiple <Suspense> fallbacks. To improve maintainability and enable reuse, extract it into a standalone file and import it where needed.

Key changes:

• Create a new file src/components/ui/OptimizedFallback.tsx with the exported component:

  // src/components/ui/OptimizedFallback.tsx
  import React from 'react';
  import { cn } from '@/lib/utils';
  
  export const OptimizedFallback = ({
    className,
    children,
  }: {
    className?: string;
    children?: React.ReactNode;
  }) => (
    <div className={cn("animate-pulse", className)}>
      <div className="h-8 bg-gray-200 rounded w-full mb-4"></div>
      <div className="h-4 bg-gray-200 rounded w-3/4 mb-2"></div>
      <div className="h-4 bg-gray-200 rounded w-1/2"></div>
      {children}
    </div>
  );

• In src/components/LazyComponents.tsx, remove the inline OptimizedFallback and add:

  - const OptimizedFallback = ({ className, children }: { className?: string; children?: React.ReactNode }) => (…);
  + import { OptimizedFallback } from '@/components/ui/OptimizedFallback';

• Update all <Suspense> fallbacks to use the imported component:

  <Suspense fallback={<OptimizedFallback className="min-h-[200px]" />} />
  <Suspense fallback={<OptimizedFallback className="min-h-[150px]" />} />
  <Suspense fallback={<OptimizedFallback className="min-h-[300px]" />} />

This refactoring centralizes the fallback UI, reduces duplication, and makes future style tweaks or enhancements trivial.

84-98: Improve image format handling logic

The current check src.includes('lovable-uploads') on Lines 87 and 94 is fragile and makes assumptions about URL patterns. This could break if the CDN changes or for other image sources.

+  // Check if the source supports format conversion
+  const supportsFormatConversion = useCallback((url: string) => {
+    // External URLs or specific CDNs might not support format conversion
+    const unsupportedPatterns = ['lovable-uploads', 'githubusercontent', 'unsplash'];
+    return !unsupportedPatterns.some(pattern => url.includes(pattern));
+  }, []);

   return (
     <div className={cn("relative overflow-hidden", className)}>
       {/* ... */}
       <picture>
         {/* AVIF format for modern browsers */}
         <source
-          srcSet={src.includes('lovable-uploads') ? src : srcSet.replace('webp', 'avif')}
+          srcSet={supportsFormatConversion(src) ? avifSrc : src}
           type="image/avif"
           sizes={sizes}
         />
         
         {/* WebP format */}
         <source
-          srcSet={src.includes('lovable-uploads') ? src : srcSet}
+          srcSet={supportsFormatConversion(src) ? srcSet : src}

+    // Handle optional port: git@host:port:owner/repo.git -> ssh://git@host:port/owner/repo.git
+    ? sanitized.replace(/^git@([^:]+):(\d+:)?/, (_, host, port) =>

  if (RESERVED_SUBDOMAINS.includes(subdomain.toLowerCase())) {
    return false;
  }

  // const existing = await db.subdomains.findOne({ subdomain: subdomain.toLowerCase() });
  // return !existing;

Many minimal base images don’t ship curl by default. If your Dockerfile doesn’t add it, healthchecks will flap.

Two options:

• Install curl in the image (recommended for ops parity), or
• Use CMD-SHELL and a POSIX sh + wget (if available).

Example:

-    healthcheck:
-      test: ["CMD", "curl", "-f", "http://localhost:3000/health"]
+    healthcheck:
+      test: ["CMD-SHELL", "curl -fsS http://localhost:3000/health >/dev/null || exit 1"]
       interval: 30s
       timeout: 10s
       retries: 3
       start_period: 40s

If curl is not available, switch to wget -qO- accordingly.

21-23: Log volume can hit permissions issues with non-root containers

Mounting ./logs:/app/logs is good, but if the container runs as a non-root user (recommended), ensure the host directory exists and is writable.

Document or create the directory with appropriate ownership, or mount a named volume and chown in entrypoint.

api/deploy.ts (5)

488-491: Use configured base domain, not a literal

const domain = ${subdomain}.zapdev.link`` duplicates configuration and can drift.

Refer to deploymentConfig.baseDomain:

-  const domain = `${subdomain}.zapdev.link`;
+  const domain = `${subdomain}.${deploymentConfig.baseDomain}`;

31-59: Don’t swallow analytics errors twice; let the manager log

PostHogAnalytics.track catches and suppresses errors, and later the manager also wraps .track with its own try/catch. The inner catch prevents the manager from logging failures.

Remove the inner try/catch or at least rethrow. Example:

-    try {
-      const payload = { /* ... */ };
-      await fetch(`${this.host}/capture/`, { /* ... */ });
-    } catch {
-      // Silently fail analytics
-    }
+    const payload = { /* ... */ };
+    await fetch(`${this.host}/capture/`, { /* ... */ });

330-336: Avoid logging raw client IP (PII) in routine INFO logs

Storing IPs can introduce privacy obligations. Unless you have a DPA/legal basis, prefer masking or hashing.

Mask last octet: a.b.c.xxx, or hash via a stable salt before logging.

---

407-421: Default subdomain generation may violate your own validation

When subdomain is omitted, you derive it from projectName without trimming leading/trailing hyphens. The manager will reject invalid cases later, causing a 400. You can fail fast and give a clearer message.

Sanitize further:

-    subdomain: subdomain || projectName.toLowerCase().replace(/[^a-z0-9-]/g, '-'),
+    subdomain: subdomain || projectName
+      .toLowerCase()
+      .replace(/[^a-z0-9-]/g, '-')
+      .replace(/^-+/, '')
+      .replace(/-+$/, '')
+      .slice(0, 63),

8-17: Standardize ESM import extensions across API and lib
The library files in lib/deployment/*.ts consistently import their own modules with the .js extension (e.g. import … from './types.js'), whereas the API endpoints in api/*.ts omit it. Under NodeNext’s strict ESM resolution, these mixed imports will break at runtime.

Please update the API imports to match the .js extensions used in the libs:

• api/domains.ts

• Line 9:

  -import { ZapdevDeploymentManager } from '../lib/deployment/manager';
  +import { ZapdevDeploymentManager } from '../lib/deployment/manager.js';

• Line 16:

  -} from '../lib/deployment/types';
  +} from '../lib/deployment/types.js';

• api/deploy.ts

• Line 9:

  -import { ZapdevDeploymentManager } from '../lib/deployment/manager';
  +import { ZapdevDeploymentManager } from '../lib/deployment/manager.js';

• Line 17:

  -} from '../lib/deployment/types';
  +} from '../lib/deployment/types.js';

Adopting this change will ensure consistent module resolution and prevent build failures under ESM/NodeNext.

Code Review: Fix Vercel Deployment Build Errors

I've completed a comprehensive review of this PR. While the changes successfully address the Vercel deployment build errors, I've identified several security concerns and code quality issues that should be addressed before merging.

Review Summary

✅ Positive Aspects:

• Successfully fixes TypeScript compilation errors
• Proper authentication verification in API endpoints
• Good error handling and logging practices
• Follows project guidelines from CLAUDE.md

🚨 Critical Security Issues:

1. Environment Validation Logic (api/deploy.ts:94-100)

// PROBLEMATIC: Requires BOTH tokens even when only one platform is needed
if (!netlifyAccessToken) missingVars.push('NETLIFY_ACCESS_TOKEN');
if (!vercelAccessToken) missingVars.push('VERCEL_ACCESS_TOKEN');

Issue: The validation fails unless BOTH Netlify and Vercel tokens are present, but the deployment manager can work with either platform.
Fix: Require at least one token, not both.

2. Eager Environment Validation (api/deploy.ts:123)

const validatedEnv = validateEnvironmentVariables(); // At module load!

Issue: This will crash the entire endpoint if tokens are missing, preventing even OPTIONS requests.
Fix: Move validation inside request handlers or make it lazy.

3. Duplicate Secret Storage (api/deploy.ts:126-135)

interface ZapdevDeploymentConfigWithSecrets extends ZapdevDeploymentConfig {
  netlify: { accessToken: string; teamId?: string; };
  vercel: { accessToken: string; teamId?: string; };
}

Issue: Access tokens are stored in both config and secrets objects, increasing leakage risk.
Fix: Keep tokens only in the secrets object.

4. Type Assertion Issues

api/create-checkout-session.ts:24, 36:

res.setHeader('Access-Control-Allow-Origin', requestOrigin as string);

Issue: Unsafe type assertion when requestOrigin is already validated.
Fix: Use non-null assertion requestOrigin! instead.

api/secret-chat.ts:27:

const authResult = await verifyAuth({ headers: new Headers(req.headers as Record<string, string>) });

Issue: Forces headers to string-only when they can be string arrays.
Fix: Remove the type assertion to allow proper header handling.

api/hono-trpc.ts:34-36:

createContext: async (opts: FetchCreateContextFnOptions, c) => {
  const context = await createContext({ req: opts.req });
  return context as Record<string, unknown>; // Unnecessary cast
},

Issue: Unused parameter c and unnecessary type assertion.
Fix: Remove unused parameter and type assertion.

5. Duplicate Authorization Header Processing (api/success.ts:19-31)

// Lines 19-23: First processing
const rawAuthHeader = Array.isArray(req.headers['authorization'])
  ? req.headers['authorization'][0] : req.headers['authorization'];

// Lines 28-32: Identical duplicate processing
const rawAuthHeader = Array.isArray(req.headers['authorization'])
  ? req.headers['authorization'][0] : req.headers['authorization'];

Issue: Code duplication that suggests copy-paste error.
Fix: Remove the duplicate processing.

6. Hard-coded Domain References

api/deploy.ts:489, lib/deployment/manager.ts:336:

const domain = `${subdomain}.zapdev.link`; // Hard-coded!
subdomain: domain.replace('.zapdev.link', ''), // Hard-coded!

Issue: Should use deploymentConfig.baseDomain instead of hard-coding "zapdev.link".

Performance & Code Quality Issues

7. Incomplete Fetch in Analytics (api/deploy.ts:56)

await fetch(`${this.host}/capture/`, { /* ... */ }); // Missing catch!

Issue: The await suggests error handling, but the outer try/catch silently swallows all errors.
Fix: Either remove await or let errors bubble up for logging.

8. Inconsistent ESM Import Extensions

The codebase mixes imports with and without .js extensions:

• Library files: from './types.js' ✅
• API files: from '../lib/deployment/manager' ❌

Fix: Add .js extensions to all API imports for NodeNext compatibility.

Minor Issues

• vite.config.ts: Configuration looks good with proper PWA settings
• lib/deployment/manager.ts: Minor import inconsistency with inline type imports
• api/domains.ts: Good separation of concerns but should also use configurable base domain

Recommendations

1. Before merging:

   • Fix the environment validation logic to require only one platform token
   • Remove duplicate secret storage
   • Fix type assertions throughout the codebase
   • Make domain references configurable

2. Authentication: All API routes properly implement authentication ✅

3. Error handling: Generally good, but could be more consistent

4. Performance: Changes don't introduce performance regressions

5. Test coverage: Consider adding tests for the new deployment validation logic

Overall Assessment: The PR fixes the immediate build issues but introduces several security and maintainability concerns that should be addressed before production deployment.
