Codebase SummaryThis repository is a web application that integrates Better Auth with Convex as its backend database, along with Polar.sh integration. The project includes both frontend components (Next.js, React) and backend configurations (Convex mutations/queries). The application handles email/password authentication, social OAuth (Google, GitHub), session management, and custom error/CORS handling. Additional documentation and utility scripts, such as orphaned project cleanup, are provided. PR ChangesThe pull request implements multiple changes including:
Setup Instructions
Generated Test Cases1: Email/Password Sign-Up Flow ❗️❗️❗️Description: Tests the complete sign-up process using email and password. Ensures that after filling the sign-up form, the user is properly created and redirected to the dashboard with an active session. Prerequisites: Steps:
Expected Result: The user is successfully registered, a new account is created in the backend, and the dashboard displays a personalized welcome message. A session token is stored and the user remains logged in. 2: Email/Password Sign-In Flow ❗️❗️❗️Description: Validates that an existing user can log in using email and password and that the UI updates to reflect the authenticated state. Prerequisites:
Steps:
Expected Result: The user is successfully authenticated, and the UI reflects the logged-in state (e.g., welcome message, profile info visible, and logout button displayed). 3: OAuth Sign-In Flow (Google) ❗️❗️❗️Description: Checks the OAuth workflow by triggering a sign-in with a social provider (Google). Validates redirection and session creation when authentication is successful. Prerequisites:
Steps:
Expected Result: The OAuth sign-in process completes successfully, the user is authenticated, and session information is visible in the UI. 4: Custom Authentication Pop-Up Display ❗️❗️Description: Ensures that the custom pop-up for authentication is triggered when initiating a sign-in and that it displays all necessary elements. Prerequisites:
Steps:
Expected Result: The custom authentication pop-up is displayed with all required input fields and buttons, then properly dismissed when closed. 5: Session Persistence After Page Refresh ❗️❗️❗️Description: Verifies that after a user has signed in, refreshing the page retains the session and the authenticated state. Prerequisites:
Steps:
Expected Result: The user remains logged in after a page refresh, with persistent session data displayed in the UI. 6: Error Handling When Wrong Password is Entered ❗️❗️Description: Tests the scenario where a user attempts to sign in with incorrect credentials and observes an error message. Prerequisites:
Steps:
Expected Result: An error message is displayed indicating that the credentials are incorrect, and the UI remains on the sign-in screen without redirecting. 7: Navigation and Layout Check for Auth Pages ❗️Description: Ensures that the overall layout, including header, footer, and authentication buttons, is rendered correctly on the sign-in and sign-up pages. Prerequisites: Steps:
Expected Result: The UI is correctly laid out, with all elements (header, footer, forms, buttons) properly aligned and styled as per design specifications. Raw Changes AnalyzedFile: convex/importData.ts

+# Better Auth + Convex Integration Guide
+
+This guide explains how Better Auth and Convex are linked together in ZapDev, and what each component does.
+
+## Overview
+
+Better Auth is a modern authentication framework that needs a database to store users, sessions, and OAuth accounts. Instead of using a traditional SQL database, we use **Convex** (a real-time database) as the backend.
+
+The connection is made through a **Custom Database Adapter** that implements Better Auth's `DatabaseAdapter` interface, routing all auth operations to Convex mutations and queries.
+
+## Architecture

+```
+
+## Database Tables
+
+### 1. Users Table (`users`)
+
+Stores user account information and subscription data.
+
+```typescript
+{
+ email: string; // Unique email
+ emailVerified: boolean; // Email verification status
+ name?: string; // User's full name
+ image?: string; // Avatar URL
+
+ // Polar.sh subscription fields
+ polarCustomerId?: string; // Linked to Polar account
+ subscriptionId?: string; // Active subscription ID
+ subscriptionStatus?: string; // "active", "canceled", "past_due", etc.
+ plan?: "free" | "pro"; // Current plan tier
+
+ createdAt: number; // Timestamp
+ updatedAt: number; // Timestamp
+}
+
+// Indexes
+.index("by_email", ["email"])
+.index("by_polarCustomerId", ["polarCustomerId"])
+```
+
+**When records are created**:
+- User signs up with email/password
+- User signs in with OAuth (Google/GitHub)
+- Better Auth automatically creates/updates via adapter
+
+### 2. Sessions Table (`sessions`)
+
+Manages user login sessions with expiration and renewal.
+
+```typescript
+{
+ userId: Id<"users">; // Reference to user
+ expiresAt: number; // Session expiration timestamp
+ token: string; // Session token (httpOnly cookie)
+ ipAddress?: string; // Client IP for security
+ userAgent?: string; // Browser info
+}
+
+// Indexes
+.index("by_userId", ["userId"])
+.index("by_token", ["token"])
+```
+
+**Session lifecycle**:
+1. User logs in → `sessions.create()` called
+2. Session stored with 7-day expiration
+3. Each request updates `updatedAt`
+4. If `updatedAt + updateAge < now`, session is refreshed automatically
+5. Expired sessions returned as `null` by `getByToken()`
+6. User logs out → `sessions.deleteByToken()` called
+
+### 3. Accounts Table (`accounts`)
+
+Stores OAuth provider connections (Google, GitHub, etc.).
+
+```typescript
+{
+ userId: Id<"users">; // User this account belongs to
+ provider: string; // "google" or "github"
+ providerAccountId: string; // Provider's user ID
+ accessToken?: string; // OAuth access token
+ refreshToken?: string; // OAuth refresh token
+ expiresAt?: number; // Token expiration
+ tokenType?: string; // "Bearer", etc.
+ scope?: string; // Permission scope
+ idToken?: string; // OpenID Connect ID token
+}
+
+// Indexes
+.index("by_provider_accountId", ["provider", "providerAccountId"])
+.index("by_userId", ["userId"])
+```
+
+**OAuth flow**:
+1. User clicks "Sign in with Google"
+2. Redirected to Google consent screen
+3. Google redirects back with authorization code
+4. Better Auth exchanges code for tokens
+5. Adapter stores in `accounts` table
+6. On next request, tokens are checked for expiration
+7. If expired, automatically refreshed using `refreshToken`
+
+### 4. Email Verifications Table (`emailVerifications`)
+
+Optional: Stores email verification tokens.
+
+```typescript
+{
+ userId: Id<"users">;
+ email: string;
+ token: string; // Unique verification token
+ expiresAt: number; // Token expiration
+ verified: boolean; // Verification status
+ createdAt: number;
+}
+
+// Indexes
+.index("by_token", ["token"])
+.index("by_userId", ["userId"])
+.index("by_email", ["email"])
+```
+
+Currently **email verification is disabled** in `src/lib/auth.ts`:
+```typescript
+emailAndPassword: {
+ enabled: true,
+ requireEmailVerification: false, // ← Set to true to enable
+}
+```

+ // Base URL for auth endpoints
+ baseURL: "http://localhost:3000", // dev
+ // or "https://zapdev-mu.vercel.app" // prod
+
+ // Use Convex as database
+ database: createConvexAdapter(),
+
+ // Email & password authentication

+| `requireEmailVerification` | false | Require email verification before login |
+
+## Database Adapter
+
+### src/lib/auth-adapter-convex.ts
+
+This file is the **bridge** between Better Auth and Convex. It implements the `DatabaseAdapter` interface with these methods:
+
+#### User Operations
+```typescript
+async createUser(user): Promise<User>
+async getUser(id): Promise<User | null>
+async getUserByEmail(email): Promise<User | null>
+async updateUser(id, updates): Promise<User | null>
+async deleteUser(id): Promise<boolean>
+```
+
+Maps to Convex mutations:
+- `api.users.createOrUpdate`
+- `api.users.getById`
+- `api.users.getByEmail`
+- `api.users.update`
+- `api.users.deleteUser`
+
+#### Session Operations
+```typescript
+async createSession(session): Promise<Session>
+async getSession(token): Promise<Session | null>
+async updateSession(token, updates): Promise<Session | null>
+async deleteSession(token): Promise<boolean>
+```
+
+Maps to Convex mutations:
+- `api.sessions.create`
+- `api.sessions.getByToken`
+- `api.sessions.updateByToken`
+- `api.sessions.deleteByToken`
+
+#### OAuth Operations
+```typescript
+async createAccount(account): Promise<Account>
+async getAccount(provider, providerAccountId): Promise<Account | null>
+async updateAccount(provider, providerAccountId, updates): Promise<Account | null>
+async deleteAccount(provider, providerAccountId): Promise<boolean>
+```
+
+Maps to Convex mutations:
+- `api.accounts.create`
+- `api.accounts.getByProvider`
+- `api.accounts.update`
+- `api.accounts.deleteOAuth`
+
+**Special feature**: The `getAccount()` method automatically detects expired OAuth tokens and refreshes them using the `refreshToken`:
+
+```typescript
+// In getAccount():
+if (isOAuthTokenExpired(expiresAt) && refreshToken) {
+ const refreshResult = await refreshOAuthTokenForProvider(
+ provider,
+ refreshToken,
+ clientId,
+ clientSecret
+ );
+ // Update database with new token
+ await this.updateAccount(provider, providerAccountId, {
+ accessToken: refreshResult.accessToken,
+ expiresAt: Date.now() + refreshResult.expiresIn * 1000
+ });
+}
+```
+
+## API Routes
+
+### src/app/api/auth/[...all]/route.ts
+
+Handles all authentication HTTP requests:
+
+```typescript
+export async function POST(request: Request) {
+ // Rate limiting check
+ const rateLimitResult = await checkRateLimit(request);
+ if (!rateLimitResult.success) {
+ return rateLimitResult.response;
+ }
+
+ // Route to Better Auth handler
+ const handlers = toNextJsHandler(auth);
+ return handlers.POST(request);
+}
+
+export async function GET(request: Request) {
+ // OAuth callbacks don't need rate limiting
+ const handlers = toNextJsHandler(auth);
+ return handlers.GET(request);
+}
+```
+
+**Endpoints created automatically by Better Auth**:
+
+| Endpoint | Method | Purpose |
+|----------|--------|---------|
+| `/api/auth/sign-up` | POST | Register with email/password |
+| `/api/auth/sign-in` | POST | Login with email/password |
+| `/api/auth/sign-out` | POST | Logout (invalidate session) |
+| `/api/auth/session` | GET | Get current session |
+| `/api/auth/signin/google` | GET | Start Google OAuth |
+| `/api/auth/callback/google` | GET | Handle Google redirect |
+| `/api/auth/signin/github` | GET | Start GitHub OAuth |
+| `/api/auth/callback/github` | GET | Handle GitHub redirect |
+
+**Rate limiting** is applied to sign-up/login endpoints to prevent brute force attacks.
+
+## Client Integration
+
+### src/lib/auth-client.ts
+
+Frontend auth client:
+
+```typescript
+export const authClient = createAuthClient({
+ baseURL: "http://localhost:3000"
+});
+
+export const {
+ signIn,
+ signUp,
+ signOut,
+ useSession,
+} = authClient;
+```
+
+**Usage in React components**:
+
+```typescript
+import { useSession, signIn, signOut } from "@/lib/auth-client";
+
+function Profile() {
+ const { data: session } = useSession();
+
+ if (!session) {
+ return <div>Not logged in</div>;
+ }
+
+ return (
+ <div>
+ <p>Welcome, {session.user.name}!</p>
+ <button onClick={() => signOut()}>Logout</button>
+ </div>
+ );
+}
+```
+
+## Data Flow Examples
+
+### 1. Email/Password Sign-Up
+
+```
+User clicks "Sign Up"
+ ↓
+Form submits email & password
+ ↓
+POST /api/auth/sign-up
+ ↓
+Better Auth validates
+ ↓
+Convex Adapter: createUser()
+ ↓
+Convex Mutation: users.createOrUpdate()
+ ↓
+Insert into users table
+ ↓
+Convex Adapter: createSession()
+ ↓
+Convex Mutation: sessions.create()
+ ↓
+Insert into sessions table
+ ↓
+Response: { token, user }
+ ↓
+Client stores in httpOnly cookie
+ ↓
+React re-renders with useSession()
+```
+
+### 2. OAuth Sign-In (Google)
+
+```
+User clicks "Sign in with Google"
+ ↓
+GET /api/auth/signin/google
+ ↓
+Better Auth: redirect to Google consent screen
+ ↓
+User authorizes
+ ↓
+Google redirects to /api/auth/callback/google?code=...
+ ↓
+Better Auth exchanges code for access token
+ ↓
+Convex Adapter: getUserByEmail()
+ ↓
+If user exists:
+ ├─ Convex Adapter: getAccount()
+ ├─ Check if OAuth token is expired
+ ├─ If expired, refresh automatically
+ ├─ Convex Adapter: getSession() (existing session)
+ └─ Return existing session
+ ↓
+If user not found:
+ ├─ Convex Adapter: createUser()
+ ├─ Convex Adapter: createAccount() (store OAuth tokens)
+ ├─ Convex Adapter: createSession()
+ └─ Return new session
+ ↓
+Client receives session token in httpOnly cookie
+```
+
+### 3. Session Validation on Page Load
+
+```
+User loads app
+ ↓
+Browser sends request with session cookie
+ ↓
+Frontend calls useSession()
+ ↓
+Better Auth reads cookie
+ ↓
+Convex Adapter: getSession(token)
+ ↓
+Query sessions table
+ ↓
+If expiresAt < now: return null (expired)
+ ↓
+If expiresAt > now && (updatedAt + updateAge < now):
+ ├─ Convex Adapter: updateSession()
+ ├─ Set new expiresAt
+ └─ Return updated session
+ ↓
+Client receives session with user data

+
+## Environment Variables
+
+Required for Better Auth + Convex to work:
+
+```bash
+# Application URL
+NEXT_PUBLIC_APP_URL=http://localhost:3000
+
+# Better Auth
+BETTER_AUTH_SECRET=<generate with: openssl rand -base64 32>
+BETTER_AUTH_URL=http://localhost:3000
+
+# Convex
+NEXT_PUBLIC_CONVEX_URL=<your-convex-url>
+CONVEX_DEPLOYMENT=<deployment-id>
+
+# OAuth Providers (optional)
+GOOGLE_CLIENT_ID=<from Google Console>
+GOOGLE_CLIENT_SECRET=<from Google Console>
+GITHUB_CLIENT_ID=<from GitHub Settings>
+GITHUB_CLIENT_SECRET=<from GitHub Settings>
+
+# Polar.sh (billing)
+POLAR_ACCESS_TOKEN=<token>
+POLAR_ORGANIZATION_ID=<id>
+NEXT_PUBLIC_POLAR_PRODUCT_ID_PRO=<product-id>
+POLAR_WEBHOOK_SECRET=<secret>
+```
+
+See `.env.example` and `explanations/BETTER_AUTH_POLAR_SETUP.md` for complete setup.
+
+## Advanced: Email Verification
+
+To enable email verification:
+
+1. **Update Better Auth config** (`src/lib/auth.ts`):
+```typescript
+emailAndPassword: {
+ enabled: true,
+ requireEmailVerification: true // ← Change this
+}
+```
+
+2. **Setup email provider** (nodemailer, SendGrid, Resend, etc.):
+```typescript
+import { sendEmailVerificationEmail } from "@/lib/email";
+
+// In auth config
+emailAndPassword: {
+ enabled: true,
+ requireEmailVerification: true,
+ sendVerificationEmail: async (email, token) => {
+ await sendEmailVerificationEmail(email, token);
+ }
+}
+```
+
+3. **Verify email endpoint**:
+```typescript
+// POST /api/auth/verify-email?token=...
+// Better Auth handles this automatically
+```
+
+The `convex/emailVerifications.ts` module provides:
+- `createVerification()` - Generate token
+- `getByToken()` - Retrieve verification
+- `markVerified()` - Mark email as verified
+- `deleteExpired()` - Cleanup old tokens
+
+## Troubleshooting
+
+### Session not persisting across page reload
+**Cause**: Session token not in httpOnly cookie
+**Fix**: Check `BETTER_AUTH_URL` and `NEXT_PUBLIC_APP_URL` match exactly
+
+### OAuth token refresh not working
+**Cause**: OAuth credentials missing or incorrect
+**Fix**: Verify `GOOGLE_CLIENT_ID`, `GOOGLE_CLIENT_SECRET`, etc. in environment
+
+### "User not found" errors
+**Cause**: Convex adapter failing to create user
+**Fix**: Check network tab → `/api/auth/sign-up` response for error details
+
+### Sessions expiring too quickly
+**Cause**: `expiresIn` set to low value
+**Fix**: Adjust in `src/lib/auth.ts` → `session.expiresIn`
+
+### Rate limiting blocking legitimate requests
+**Cause**: Too many auth attempts from same IP
+**Fix**: Whitelist IP or adjust `checkRateLimit()` threshold in rate-limit.ts
+
+## Testing the Integration
+
+### Manual test: Email/Password Sign-Up
+```bash
+# 1. Start dev server
+bun run dev
+bun run convex:dev # in another terminal
+
+# 2. Open http://localhost:3000
+# 3. Click "Sign Up"
+# 4. Enter email & password
+# 5. Check Convex dashboard:
+# - users table should have new entry
+# - sessions table should have new session
+# 6. Refresh page - session should persist
+```
+
+### Manual test: Google OAuth
+```bash
+# 1. Configure GOOGLE_CLIENT_ID & GOOGLE_CLIENT_SECRET in .env.local
+# 2. Start dev server
+# 3. Click "Sign in with Google"
+# 4. Authorize
+# 5. Check Convex dashboard:
+# - users table has new user
+# - accounts table has Google connection
+# 6. Sign out and sign in again - should use existing session
+```
+
+### Manual test: Session Refresh
+```bash
+# 1. Sign in
+# 2. Keep browser open for > 1 day (or manually set expiresAt to 1 day ago)
+# 3. Make a request (refresh page)
+# 4. Check Convex: sessions table expiresAt should update to future date
+```
+
+## Security Considerations
+
+1. **Session tokens**: Stored in httpOnly cookies (secure by default)
+2. **CSRF protection**: Enabled by default in Better Auth
+3. **Password hashing**: Better Auth uses bcrypt automatically
+4. **OAuth tokens**: Never exposed in client-side code
+5. **Rate limiting**: POST endpoints protected against brute force
+6. **Email verification**: Optional but recommended for production

+## Frontend Usage
+
+### Get Current Session
+```typescript
+import { useSession } from "@/lib/auth-client";
+
+function Component() {
+ const { data: session, isPending } = useSession();
+
+ if (isPending) return <div>Loading...</div>;
+ if (!session) return <div>Not logged in</div>;
+
+ return <div>Welcome {session.user.name}!</div>;
+}
+```
+
+### Sign In
+```typescript
+import { signIn } from "@/lib/auth-client";
+
+async function LoginForm() {
+ const { data, error } = await signIn.email({
+ email: "user@example.com",
+ password: "password123",
+ onSuccess: () => {
+ // Redirect to dashboard
+ window.location.href = "/dashboard";
+ },
+ });
+
+ if (error) console.error(error.message);
+}
+```
+
+### Sign Up
+```typescript
+import { signUp } from "@/lib/auth-client";
+
+async function RegisterForm() {
+ const { data, error } = await signUp.email({
+ email: "newuser@example.com",
+ password: "securepassword",
+ name: "John Doe",
+ onSuccess: () => {
+ window.location.href = "/dashboard";
+ },
+ });
+
+ if (error) console.error(error.message);
+}
+```
+
+### Sign Out
+```typescript
+import { signOut } from "@/lib/auth-client";
+
+async function LogoutButton() {
+ const { error } = await signOut();
+ if (error) console.error(error);
+}
+```
+
+### OAuth Sign-In
+```typescript
+import { signIn } from "@/lib/auth-client";
+
+async function GoogleLoginButton() {
+ // Automatically redirects to Google
+ await signIn.social({
+ provider: "google",
+ });
+}
+
+async function GitHubLoginButton() {
+ // Automatically redirects to GitHub
+ await signIn.social({
+ provider: "github",
+ });
+}
+```
+
+## Backend Usage
+
+### Get Current User (Server-Side)
+```typescript
+import { auth } from "@/lib/auth";
+
+export async function GET(request: Request) {
+ const session = await auth.api.getSession({ headers: request.headers });
+
+ if (!session) {
+ return new Response("Unauthorized", { status: 401 });
+ }
+
+ return Response.json({ user: session.user });
+}
+```
+
+### Get User by Email (Convex)
+```typescript
+import { fetchQuery } from "convex/nextjs";
+import { api } from "@/convex/_generated/api";
+
+const user = await fetchQuery(api.users.getByEmail, {
+ email: "user@example.com"
+});
+```
+
+### Check if User Has OAuth Account
+```typescript
+const { data: session } = useSession();
+const accounts = await fetchQuery(api.accounts.getByUserId, {
+ userId: session.user.id
+});
+
+const hasGoogle = accounts.some(a => a.provider === "google");
+```
+
+### Get Session by Token
+```typescript
+const session = await fetchQuery(api.sessions.getByToken, {
+ token: "session_token_here"
+});
+
+if (session && session.expiresAt < Date.now()) {
+ console.log("Session expired");
+}
+```
+
+## Convex Patterns
+
+### List All Users (Dangerous - For Admin Only!)
+```typescript
+import { query } from "./_generated/server";
+
+export const getAllUsers = query({
+ args: {},
+ handler: async (ctx) => {
+ return await ctx.db.query("users").collect();
+ }
+});
+```
+
+### Check if Email is Taken
+```typescript
+import { query } from "./_generated/server";
+
+export const isEmailTaken = query({
+ args: { email: v.string() },
+ handler: async (ctx, args) => {
+ const user = await ctx.db
+ .query("users")
+ .withIndex("by_email", q => q.eq("email", args.email))
+ .first();
+
+ return !!user;
+ }
+});
+```
+
+### Update User Profile
+```typescript
+import { fetchMutation } from "convex/nextjs";
+import { api } from "@/convex/_generated/api";
+
+const userId = session.user.id;
+await fetchMutation(api.users.update, {
+ userId,
+ name: "New Name",
+ image: "https://example.com/avatar.jpg"
+});
+```
+
+### Disconnect OAuth Provider
+```typescript
+import { fetchMutation } from "convex/nextjs";
+import { api } from "@/convex/_generated/api";
+
+await fetchMutation(api.accounts.deleteOAuth, {
+ provider: "google",
+ providerAccountId: "1234567890"
+});
+```
+
+### Delete User Account
+```typescript
+import { fetchMutation } from "convex/nextjs";
+import { api } from "@/convex/_generated/api";
+
+await fetchMutation(api.users.deleteUser, {
+ userId: session.user.id
+});
+```
+
+## Common Queries
+
+### Get All Sessions for Current User
+```typescript
+import { fetchQuery } from "convex/nextjs";
+import { api } from "@/convex/_generated/api";
+
+const { data: session } = useSession();
+const sessions = await fetchQuery(api.sessions.getByUserId, {
+ userId: session.user.id
+});
+```
+
+### Get All Connected OAuth Accounts
+```typescript
+import { fetchQuery } from "convex/nextjs";
+import { api } from "@/convex/_generated/api";
+
+const { data: session } = useSession();
+const accounts = await fetchQuery(api.accounts.getByUserId, {
+ userId: session.user.id
+});
+
+// Example: ["google", "github"]
+const providers = accounts.map(a => a.provider);
+```
+
+### Check Subscription Status
+```typescript
+import { fetchQuery } from "convex/nextjs";
+import { api } from "@/convex/_generated/api";
+
+const { data: session } = useSession();
+const subscriptionStatus = await fetchQuery(api.users.getSubscriptionStatus, {
+ userId: session.user.id
+});
+
+console.log(subscriptionStatus.plan); // "free" | "pro"
+```
+
+## Configuration
+
+### Session Expiration
+In `src/lib/auth.ts`:
+```typescript
+session: {
+ expiresIn: 7 * 24 * 60 * 60, // 7 days (change this)
+ updateAge: 24 * 60 * 60, // Refresh after 1 day
+}
+```
+
+### Disable OAuth Provider
+In `src/lib/auth.ts`:
+```typescript
+socialProviders: {
+ google: {
+ enabled: false // ← Disable
+ }
+}
+```
+
+### Enable Email Verification
+In `src/lib/auth.ts`:
+```typescript
+emailAndPassword: {
+ enabled: true,
+ requireEmailVerification: true // ← Change to true
+}
+```
+
+### Change Cookie Prefix
+In `src/lib/auth.ts`:
+```typescript
+advanced: {
+ cookiePrefix: "myapp." // Cookie names: myapp.session_token, etc.
+}
+```
+
+## Environment Variables
+
+Create `.env.local`:
+```bash
+# Required
+NEXT_PUBLIC_CONVEX_URL=https://xyz.convex.cloud
+NEXT_PUBLIC_APP_URL=http://localhost:3000
+BETTER_AUTH_SECRET=<generate with: openssl rand -base64 32>
+
+# OAuth (Optional)
+GOOGLE_CLIENT_ID=...
+GOOGLE_CLIENT_SECRET=...
+GITHUB_CLIENT_ID=...
+GITHUB_CLIENT_SECRET=...
+
+# Billing
+POLAR_ACCESS_TOKEN=...
+POLAR_WEBHOOK_SECRET=...
+```
+
+## Debugging
+
+### Check Session in Browser Console
+```javascript
+// Get session token from cookie
+document.cookie.split(';').find(c => c.includes('session_token'))
+```
+
+### View Convex Data
+1. Open [Convex Dashboard](https://dashboard.convex.dev)
+2. Select project
+3. View `users`, `sessions`, `accounts` tables
+
+### Check API Responses
+```typescript
+// In browser console while testing
+await fetch("/api/auth/session").then(r => r.json()).then(console.log)
+```
+
+### View OAuth Token Expiration
+```typescript
+const { data: session } = useSession();
+const accounts = await fetchQuery(api.accounts.getByUserId, {
+ userId: session.user.id
+});
+
+accounts.forEach(acc => {
+ const isExpired = acc.expiresAt < Date.now();
+ console.log(`${acc.provider}: ${isExpired ? "EXPIRED" : "VALID"}`);
+});
+```
+
+## Error Handling
+
+### Graceful Fallback
+```typescript
+const { data: session, error } = useSession();
+
+if (error) {
+ console.error("Failed to fetch session:", error);
+ return <div>Unable to load user session</div>;
+}
+
+if (!session) {
+ return <div>Please log in</div>;
+}
+```
+
+### Check OAuth Token Validity
+```typescript
+import { isOAuthTokenExpired } from "@/lib/oauth-token-refresh";
+
+const account = // ... fetch from Convex
+if (isOAuthTokenExpired(account.expiresAt)) {
+ // Token is expired - attempt refresh or prompt user to re-authenticate
+}
+```
+
+## Testing Checklist
+
+- [ ] Email/password sign-up works
+- [ ] Email/password sign-in works
+- [ ] Session persists on page reload
+- [ ] Logout clears session
+- [ ] Google OAuth sign-in works
+- [ ] GitHub OAuth sign-in works
+- [ ] OAuth tokens refresh automatically
+- [ ] Account deletion removes all related data
+- [ ] Rate limiting blocks brute force attempts
+- [ ] User profile can be updated
+- [ ] OAuth providers can be disconnected
+
+## Performance Tips
+
+1. **Cache session in React Query**: Already done via `useSession()`
+2. **Use indexes**: Queries already use `.withIndex()` for common lookups
+3. **Batch operations**: Use `Promise.all()` for parallel Convex calls
+4. **Avoid N+1 queries**: Load related data in single query
+5. **Clean up expired sessions**: Run `sessions.cleanupExpired()` periodically
+
+## Migration from Other Auth Systems
+
+If migrating from Clerk, Auth0, or Supabase:
+
+1. **Export existing users** to CSV/JSON
+2. **Hash passwords** with bcrypt (if needed)
+3. **Create migration script** in `convex/`
+4. **Map user IDs** to Convex IDs (string format: "hashXXX")
+5. **Update all references** in database
+6. **Test thoroughly** before production
+
+See `explanations/MIGRATION_CONVEX_FROM_POSTGRESQL.md` for example.

+# CORS Fix Summary
+
+## Problem
+The application at `zapdev.link` was experiencing CORS errors when trying to make API requests to the authentication endpoints:
+
+```
+Access to fetch at 'https://zapdev-mu.vercel.app/api/auth/get-session'
+from origin 'https://www.zapdev.link' has been blocked by CORS policy
+```
+
+**Root Cause**: The server-side auth configuration had a hardcoded URL pointing to `zapdev-mu.vercel.app` instead of using the actual deployment domain.
+
+## Solution Implemented
+
+### 1. Fixed Server-Side Auth Configuration
+**File**: `src/lib/auth.ts`
+
+**Before**:
+```typescript
+const getBaseURL = (): string => {
+ if (process.env.NODE_ENV === "development") {
+ return "http://localhost:3000";
+ }
+ return "https://zapdev-mu.vercel.app"; // ❌ Hardcoded
+};
+```
+
+**After**:
+```typescript
+const getBaseURL = (): string => {
+ // Use environment variable first (production/staging)
+ if (process.env.BETTER_AUTH_URL) {
+ return process.env.BETTER_AUTH_URL;
+ }
+ // Development fallback
+ if (process.env.NODE_ENV === "development") {
+ return "http://localhost:3000";
+ }
+ // Last resort: use NEXT_PUBLIC_APP_URL
+ return process.env.NEXT_PUBLIC_APP_URL || "http://localhost:3000";
+};
+```
+
+### 2. Added CORS Headers to Auth API Routes
+**File**: `src/app/api/auth/[...all]/route.ts`
+
+Added:
+- `getAllowedOrigin()` function to validate and allow requests from the app's domain
+- `addCorsHeaders()` function to add proper CORS headers to all responses
+- `OPTIONS` handler for CORS preflight requests
+- CORS header support for both `GET` and `POST` handlers
+
+Features:
+- ✅ Supports both `www.zapdev.link` and `zapdev.link`
+- ✅ Allows credentials (cookies) to be sent with requests
+- ✅ Handles preflight OPTIONS requests
+- ✅ Validates origin against environment variables
+- ✅ Development-friendly (allows localhost in dev mode)
+
+### 3. Updated Next.js Global Headers
+**File**: `next.config.mjs`
+
+Added CORS headers specifically for auth API routes:
+```javascript
+{
+ source: '/api/auth/:path*',
+ headers: [
+ {
+ key: 'Access-Control-Allow-Credentials',
+ value: 'true'
+ },
+ {
+ key: 'Access-Control-Allow-Methods',
+ value: 'GET, POST, PUT, DELETE, OPTIONS'
+ },
+ {
+ key: 'Access-Control-Allow-Headers',
+ value: 'Content-Type, Authorization, Cookie'
+ },
+ ]
+}
+```
+
+### 4. Updated Documentation
+**Files Updated**:
+- `env.example` - Added important note about `BETTER_AUTH_URL`
+- `explanations/DOMAIN_CONFIGURATION_GUIDE.md` - Complete setup guide (NEW)
+- `explanations/CORS_FIX_SUMMARY.md` - This file (NEW)
+
+## What You Need to Do
+
+### Step 1: Set Environment Variables in Vercel
+
+Go to your Vercel project settings and add/update:
+
+```bash
+BETTER_AUTH_URL=https://zapdev.link
+NEXT_PUBLIC_APP_URL=https://zapdev.link
+```
+
+**Important**:
+- Use your actual domain (not `zapdev-mu.vercel.app`)
+- Include `https://` protocol
+- No trailing slashes
+- Both variables should match
+
+### Step 2: Redeploy
+
+After setting the environment variables, trigger a new deployment:
+
+```bash
+git add .
+git commit -m "Fix CORS issues with dynamic domain configuration"
+git push
+```
+
+Or trigger a redeploy in Vercel dashboard.
+
+### Step 3: Update OAuth Providers (if using)
+
+If you're using Google or GitHub OAuth, update their redirect URIs:
+
+**Google OAuth**:
+- Authorized redirect URIs: `https://zapdev.link/api/auth/callback/google`
+- Authorized JavaScript origins: `https://zapdev.link`
+
+**GitHub OAuth**:
+- Authorization callback URL: `https://zapdev.link/api/auth/callback/github`
+- Homepage URL: `https://zapdev.link`
+
+### Step 4: Update Polar.sh Webhook (if using)
+
+Update your Polar.sh webhook URL to:
+```
+https://zapdev.link/api/polar/webhooks
+```
+
+### Step 5: Test
+
+1. Clear browser cache and cookies
+2. Visit `https://zapdev.link`
+3. Try signing in
+4. Check browser console - no CORS errors should appear
+5. All API requests should go to `zapdev.link`, not `zapdev-mu.vercel.app`
+
+## How It Works
+
+### Development (localhost)
+```
+Client (localhost:3000) → Auth API (localhost:3000)
+✅ Same origin, no CORS needed
+```
+
+### Production (before fix)
+```
+Client (zapdev.link) → Auth API (zapdev-mu.vercel.app)
+❌ Different origins, CORS error
+```
+
+### Production (after fix)
+```
+Client (zapdev.link) → Auth API (zapdev.link)
+✅ Same origin, CORS headers present
+```
+
+## Technical Details
+
+### CORS Headers Added
+- `Access-Control-Allow-Origin`: Dynamically set to match request origin
+- `Access-Control-Allow-Credentials`: `true` (allows cookies)
+- `Access-Control-Allow-Methods`: `GET, POST, PUT, DELETE, OPTIONS`
+- `Access-Control-Allow-Headers`: `Content-Type, Authorization, Cookie`
+- `Access-Control-Max-Age`: `86400` (24 hours cache for preflight)
+
+### Security Features
+- Origin validation against environment variables
+- Support for both www and non-www subdomains
+- Development mode allows localhost
+- Credentials (cookies) only allowed for validated origins
+
+## Troubleshooting
+
+If you still see CORS errors after deploying:
+
+1. **Check environment variables are set in Vercel**
+ - Go to Settings → Environment Variables
+ - Verify `BETTER_AUTH_URL` and `NEXT_PUBLIC_APP_URL` are set correctly
+
+2. **Hard refresh your browser**
+ - Chrome/Firefox: `Ctrl+Shift+R` (Windows) or `Cmd+Shift+R` (Mac)
+ - Or try incognito/private mode
+
+3. **Verify deployment used new environment variables**
+ - Redeploy if environment variables were added after last deployment
+ - Check deployment logs for any errors
+
+4. **Check for www vs non-www mismatch**
+ - Ensure you're accessing the same domain set in environment variables
+ - Consider setting up a redirect from one to the other in Vercel
+
+5. **Clear all cookies for your domain**
+ - Old session cookies might cause issues
+ - Sign out completely and sign in again
+
+## Files Changed
+
+- ✅ `src/lib/auth.ts` - Dynamic base URL configuration
+- ✅ `src/app/api/auth/[...all]/route.ts` - CORS headers and OPTIONS handler
+- ✅ `next.config.mjs` - Global CORS headers for auth routes
+- ✅ `env.example` - Updated documentation
+- ✅ `explanations/DOMAIN_CONFIGURATION_GUIDE.md` - Complete setup guide
+- ✅ `explanations/CORS_FIX_SUMMARY.md` - This summary

+2. Set the required environment variables
+3. Test authentication flows
+4. Update OAuth provider settings
+5. Monitor for any remaining CORS issues

+# Domain Configuration Guide
+
+This guide will help you properly configure ZapDev to work with your custom domain and fix CORS issues.
+
+## The Problem
+
+CORS errors occur when the application's frontend and backend use different domains. For example:
+- Frontend served from: `https://zapdev.link`
+- Backend API calls going to: `https://zapdev-mu.vercel.app`
+
+This causes browser security to block the requests with CORS policy errors.
+
+## The Solution
+
+### 1. Configure Environment Variables
+
+Set these environment variables in your production deployment (Vercel, etc.):
+
+```bash
+# Your actual domain (must match what users see in their browser)
+BETTER_AUTH_URL=https://zapdev.link
+NEXT_PUBLIC_APP_URL=https://zapdev.link
+```
+
+**Important Notes:**
+- Use `https://` for production (not `http://`)
+- Don't include trailing slashes
+- Both variables should have the same value
+- If using `www.zapdev.link`, set it to that instead
+
+### 2. Vercel Configuration Steps
+
+If deploying to Vercel:
+
+1. Go to your project settings: https://vercel.com/[your-username]/[project-name]/settings/environment-variables
+
+2. Add/Update these variables:
+ - `BETTER_AUTH_URL` → `https://zapdev.link`
+ - `NEXT_PUBLIC_APP_URL` → `https://zapdev.link`
+
+3. **Important**: Redeploy after changing environment variables
+ ```bash
+ # Trigger a new deployment
+ git commit --allow-empty -m "Trigger redeploy for env vars"
+ git push
+ ```
+
+### 3. Domain Setup
+
+#### Option A: Use Root Domain Only (Recommended)
+- Primary domain: `zapdev.link`
+- Redirect `www.zapdev.link` → `zapdev.link`
+
+In Vercel:
+1. Go to Settings → Domains
+2. Add `zapdev.link` as primary
+3. Add `www.zapdev.link` and set it to redirect to `zapdev.link`
+
+Set environment variables:
+```bash
+BETTER_AUTH_URL=https://zapdev.link
+NEXT_PUBLIC_APP_URL=https://zapdev.link
+```
+
+#### Option B: Use WWW Subdomain
+- Primary domain: `www.zapdev.link`
+- Redirect `zapdev.link` → `www.zapdev.link`
+
+Set environment variables:
+```bash
+BETTER_AUTH_URL=https://www.zapdev.link
+NEXT_PUBLIC_APP_URL=https://www.zapdev.link
+```
+
+### 4. OAuth Provider Updates
+
+After changing your domain, update OAuth redirect URIs:
+
+#### Google OAuth
+1. Go to [Google Cloud Console](https://console.cloud.google.com/)
+2. Navigate to: APIs & Services → Credentials
+3. Edit your OAuth 2.0 Client ID
+4. Update Authorized redirect URIs:
+ ```
+ https://zapdev.link/api/auth/callback/google
+ ```
+5. Update Authorized JavaScript origins:
+ ```
+ https://zapdev.link
+ ```
+
+#### GitHub OAuth
+1. Go to [GitHub Settings](https://github.com/settings/developers)
+2. Edit your OAuth App
+3. Update Authorization callback URL:
+ ```
+ https://zapdev.link/api/auth/callback/github
+ ```
+4. Update Homepage URL:
+ ```
+ https://zapdev.link
+ ```
+
+### 5. Polar.sh Webhook URL
+
+Update your Polar.sh webhook endpoint:
+
+1. Go to [Polar.sh Dashboard](https://polar.sh/)
+2. Navigate to Settings → Webhooks
+3. Update webhook URL to:
+ ```
+ https://zapdev.link/api/polar/webhooks
+ ```
+
+## Testing the Fix
+
+### 1. Check Environment Variables
+After deployment, verify variables are set correctly:
+
+```bash
+# In your browser console on https://zapdev.link
+console.log(window.location.origin); // Should show https://zapdev.link
+```
+
+### 2. Test Authentication
+1. Clear browser cookies and cache
+2. Go to your domain: `https://zapdev.link`
+3. Try signing in with email/password
+4. Check browser console for any CORS errors
+5. Try OAuth sign-in (Google/GitHub)
+
+### 3. Verify API Requests
+In browser DevTools Network tab:
+- All API requests should go to `https://zapdev.link/api/*`
+- No requests should go to `zapdev-mu.vercel.app`
+- Response headers should include `Access-Control-Allow-Origin: https://zapdev.link`
+
+## Common Issues
+
+### Issue: Still seeing old domain in requests
+
+**Solution**:
+- Hard refresh: `Ctrl+Shift+R` (Windows/Linux) or `Cmd+Shift+R` (Mac)
+- Clear browser cache completely
+- Try incognito/private window
+- Verify environment variables in Vercel dashboard
+
+### Issue: OAuth redirects to wrong domain
+
+**Solution**:
+- Double-check OAuth provider settings match your domain exactly
+- Ensure no typos in redirect URIs
+- Wait a few minutes for OAuth provider changes to propagate
+
+### Issue: CORS errors persist
+
+**Solution**:
+1. Verify both `BETTER_AUTH_URL` and `NEXT_PUBLIC_APP_URL` are identical
+2. Check they match your actual domain (no www mismatch)
+3. Ensure you redeployed after setting environment variables
+4. Clear browser cache and cookies
+
+### Issue: Session cookies not working
+
+**Solution**:
+- Check that your domain supports secure cookies (HTTPS)
+- Verify `BETTER_AUTH_SECRET` is set in production
+- Clear all cookies for your domain
+- Try signing in again
+
+## Development vs Production
+
+### Development (localhost:3000)
+```bash
+BETTER_AUTH_URL=http://localhost:3000
+NEXT_PUBLIC_APP_URL=http://localhost:3000
+```
+
+### Production (zapdev.link)
+```bash
+BETTER_AUTH_URL=https://zapdev.link
+NEXT_PUBLIC_APP_URL=https://zapdev.link
+```
+
+## Verification Checklist
+
+Before going live, verify:
+
+- [ ] `BETTER_AUTH_URL` environment variable set in production
+- [ ] `NEXT_PUBLIC_APP_URL` environment variable set in production
+- [ ] Both variables use the same domain
+- [ ] Domain uses HTTPS (not HTTP)
+- [ ] No trailing slashes in URLs
+- [ ] Vercel domain settings configured correctly
+- [ ] OAuth providers updated with new redirect URIs
+- [ ] Polar.sh webhook URL updated
+- [ ] Tested sign-in flow (email + OAuth)
+- [ ] No CORS errors in browser console
+- [ ] All API requests go to correct domain
+
+## Need Help?
+
+If you're still experiencing issues:
+
+1. Check browser console for specific error messages
+2. Review Vercel deployment logs
+3. Verify all environment variables are set correctly
+4. Test in incognito mode to rule out caching issues
+
+## Technical Details
+
+The CORS fix implemented includes:
+
+1. **Dynamic base URL** (`src/lib/auth.ts`): Uses environment variables instead of hardcoded domain
+2. **CORS headers** (`src/app/api/auth/[...all]/route.ts`): Adds proper CORS headers to all auth endpoints
+3. **Preflight support**: Handles OPTIONS requests for CORS preflight checks
+4. **WWW subdomain support**: Automatically allows both www and non-www variants
+5. **Next.js headers** (`next.config.mjs`): Global CORS headers for API routes

+# Schema Validation Error Fix: Orphaned Projects Cleanup
+
+## Problem
+
+You encountered this error:
+```
+Schema validation failed.
+Document with ID "jn7034wkypcnpdyvkn0vd7r8n57tnrhf" in table "projects" does not match the schema: Value does not match validator.
+Path: .userId
+Value: "user_30xqHm23FRYopIgyfPPYsnMGqAq"
+Validator: v.id("users")
+```
+
+This error occurs when the `projects` table contains documents with `userId` values that don't reference valid user IDs in the `users` table. This typically happens after migrating from Clerk to Better Auth, where old user IDs may not be properly linked to the new user records.
+
+## Root Cause
+
+During the Clerk → Better Auth migration, some projects in the database may still reference user IDs from the old authentication system. Convex's schema enforces referential integrity by default, which means:
+
+1. **Project documents** have a `userId` field defined as `v.id("users")`
+2. **Convex validates** that every referenced ID actually exists in the referenced table
+3. **Orphaned documents** with invalid references fail validation
+
+## Solution
+
+We've created a cleanup utility that:
+1. ✅ Identifies all projects with invalid `userId` references
+2. ✅ Cascades deletion of all related data (messages, fragments, attachments)
+3. ✅ Removes the orphaned project documents
+4. ✅ Restores database integrity
+
+## How to Run the Cleanup
+
+### Prerequisites
+
+1. **Start Convex Dev Server** (in a separate terminal)
+ ```bash
+ bun run convex:dev
+ ```
+ Keep this running! The cleanup script needs it.
+
+2. **Set Environment Variables**
+ After starting `convex:dev`, you'll see output like:
+ ```
+ ✓ Convex dev server is running!
+ To open the dashboard, run:
+ > npx convex dashboard --url <YOUR_URL>
+ ```
+
+ Copy the URL and add to your `.env`:
+ ```bash
+ NEXT_PUBLIC_CONVEX_URL=<YOUR_URL>
+ ```
+
+### Run the Cleanup
+
+In a new terminal:
+```bash
+bun scripts/cleanup-orphaned-projects.ts
+```
+
+You'll see output like:
+```
+🚀 Initializing Convex client...
+ URL: https://your-deployment.convex.cloud
+
+🧹 Starting cleanup of orphaned projects...
+
+✅ Cleaned up 1 orphaned projects and related data
+ Cleaned projects: 1
+
+📋 Removed project IDs:
+ - jn7034wkypcnpdyvkn0vd7r8n57tnrhf
+
+✅ Cleanup completed successfully!
+```
+
+## What Gets Deleted
+
+The cleanup uses a cascade deletion approach to maintain data integrity:
+
+```
+Orphaned Project
+├── Messages
+│ ├── Attachments (deleted)
+│ ├── Fragments (deleted)
+│ └── Message itself (deleted)
+├── Fragment Drafts (deleted)
+└── Project itself (deleted)
+```
+
+**Important**: Only projects with invalid `userId` references are removed. All valid projects remain untouched.
+
+## Verification
+
+After running the cleanup, you can verify the fix:
+
+### 1. Check Dashboard
+```bash
+bun run convex:dev
+# Then visit: https://dashboard.convex.dev
+```
+
+Navigate to the **Data** tab and verify:
+- Projects with valid `userId` references remain
+- No documents remain with orphaned references
+
+### 2. Run the App
+```bash
+# Terminal 1: Convex dev server
+bun run convex:dev
+
+# Terminal 2: Next.js dev server
+bun run dev
+```
+
+The app should now work without schema validation errors.
+
+### 3. Test Project Creation
+1. Sign up or sign in at http://localhost:3000
+2. Create a new project
+3. Verify it saves correctly to the database
+
+## Code Changes
+
+### Files Modified
+- `convex/importData.ts` - Added `cleanupOrphanedProjects` mutation and action
+
+### New Functions
+
+**`cleanupOrphanedProjects` (internal mutation)**
+- Finds all projects with invalid `userId` references
+- Cascades deletion of related data
+- Returns count of cleaned projects
+
+**`cleanupOrphanedProjectsAction` (public action)**
+- HTTP-accessible wrapper for the cleanup function
+- Used by the cleanup script
+
+**`scripts/cleanup-orphaned-projects.ts` (admin script)**
+- CLI tool to run the cleanup from the command line
+- Provides user-friendly output
+
+## When to Run This
+
+Run this cleanup when you see the schema validation error. It's safe to run multiple times:
+
+- ✅ Safe to run multiple times (idempotent)
+- ✅ Only removes orphaned documents
+- ✅ Won't affect valid user projects
+- ✅ Can be run during development or production
+
+## Troubleshooting
+
+### Error: "NEXT_PUBLIC_CONVEX_URL is not set"
+**Solution**:
+1. Run `bun run convex:dev` first
+2. Copy the URL from the output
+3. Add to `.env`: `NEXT_PUBLIC_CONVEX_URL=<URL>`
+
+### Error: "Cannot connect to Convex"
+**Solution**:
+1. Make sure `bun run convex:dev` is still running
+2. Verify the URL in `.env` matches the dev server output
+3. Check internet connection
+
+### Cleanup shows 0 cleaned projects but error still occurs
+**Possible causes**:
+1. The orphaned data was already removed
+2. The validation error is from a different table (check the error message)
+3. New data was inserted after you ran the cleanup
+
+**Next steps**: Check the Convex dashboard directly to find the problem data.
+
+## Additional Notes
+
+### Data Safety
+- ✅ Original data is not modified before deletion
+- ✅ No data is moved or transformed
+- ✅ Only orphaned documents are removed
+- ✅ Can be re-run if needed
+
+### Performance
+- For small databases: < 1 second
+- For large databases: up to a few seconds depending on orphaned count
+
+### Future Prevention
+To prevent this issue in the future:
+
+1. **During migration**: Ensure all user references are updated to valid Convex user IDs
+2. **In validation**: Test that all `userId` references exist before creating projects
+3. **In imports**: Always validate foreign key references before inserting data

Pull Request Review: Better Auth Migration & Schema Validation FixesThis PR addresses schema validation issues from the Clerk to Better Auth migration by implementing a comprehensive cleanup utility for orphaned data. Critical Issues Found1. Security: Missing Access ControlThe 2. Performance: O(n²) ComplexityThe cleanup function loads ALL records into memory using 3. Type Safety: Excessive
|
Detailed RecommendationsFix 1: Add Authentication to Cleanup ActionThe cleanupOrphanedProjectsAction needs authentication. Currently anyone can trigger mass deletion. Recommended fix in convex/importData.ts:512-523:
Fix 2: Optimize Performance with Indexed QueriesCurrent approach loads ALL projects/usage/oauth/imports into memory which will not scale. Recommendation:
Fix 3: Remove Type Safety Issues10+ instances of "as any" casting defeat TypeScript benefits. Fix: Use proper Id<"users"> type for validUserIds Set instead of string. Fix 4: Add CORS Origin ControlAuth endpoints missing Access-Control-Allow-Origin header in next.config.mjs:28-42. Add explicit origin: process.env.NEXT_PUBLIC_APP_URL Fix 5: Add Test CoverageNo tests for cleanup logic. Add tests to verify:
What Works Well✅ Cascade deletion properly ordered (attachments -> fragments -> messages -> projects) Overall: Great migration work, but needs security and performance hardening before production. |
Review SummaryStatus: Critical Issues: 2
Medium Issues: 3
Positive: Excellent documentation, well-structured logic, solves the orphaned data problem Next Steps:
The architectural documentation (BETTER_AUTH_CONVEX_INTEGRATION.md) is exceptional and will be very helpful for maintenance. With the security and performance fixes, this will be a solid addition to the codebase. Note: PR is already merged, so these issues should be addressed in a follow-up PR. |
