refactor the API client to support auth tokens and add request cancellation on component unmount

I'll refactor the API client. Let me first check the current implementation to understand how requests are being made.

api.ts

I see the current setup. The API client is instantiated directly without any auth handling. I'll add token support with automatic refresh and AbortController for cancellation.

yes please, and make sure it handles 401 errors gracefully

Adding the auth wrapper with error handling:

UserProfile.tsx+4−1
+ const api = useCallback(() => {
+ return createApiClient({
+ ...apiConfig,
+ headers: { Authorization: `Bearer ${token}` },
+ onUnauthorized: refreshToken,
+ });
+ }, [token, refreshToken]);

Now I need to update the useAuth hook to expose the refresh function:

useAuth.ts+4−1
+ const refresh = async () => {
+ const res = await fetch('/api/refresh', {
+ method: 'POST',
+ credentials: 'include',
+ });
+ const { token } = await res.json();
+ setAccessToken(token);
+ };

the login redirect is broken after oauth callback - users are getting stuck on a blank page

Let me investigate the OAuth callback flow. I'll start by checking the middleware that handles the callback.

authMiddleware.ts

I found the issue - the state parameter from the OAuth provider isn't being validated before the redirect. This is a security issue and could also cause the blank page if the state is malformed.

can you fix it? we need this deployed today

On it. First, fixing the state validation:

authMiddleware.ts+4−1
+ const validateState = (state: string) => {
+ const decoded = Buffer.from(state, 'base64');
+ const { nonce, returnTo } = JSON.parse(decoded);
+ if (!verifyNonce(nonce)) throw new AuthError();
+ return returnTo;
+ };

Now let me check the callback handler to ensure the redirect URL is being constructed correctly...

add redis caching to the user service

I found your existing cache utility. I'll extend it for the user service.

cache.ts

Added cache wrapper with TTL support:

userService.ts+4−1
+ async getUser(id: string): Promise<User> {
+ const cached = await redis.get(`user:${id}`);
+ if (cached) return JSON.parse(cached);
+ const user = await this.db.findUser(id);
+ await redis.setex(`user:${id}`, 3600, JSON.stringify(user));
+ return user;
+ }

Also updated the types:

types.ts+4−1
+export interface CacheOptions {
+ ttl?: number;
+ prefix?: string;
+ serialize?: (v: unknown) => string;
+}

Running tests to verify the changes...

create a migration to add email_verified and last_login columns to the users table

I'll create a new migration for those columns. Let me first check your existing migrations to follow the same patterns.

migrations/001_create_users.sql

Creating the migration with proper defaults and indexes:

migrations/002_add_user_fields.sql+4−1
+ALTER TABLE users
+ ADD COLUMN email_verified BOOLEAN DEFAULT FALSE,
+ ADD COLUMN last_login TIMESTAMP NULL;
+
+CREATE INDEX idx_users_last_login ON users(last_login);

looks good, can you also update the User type?

Updated the User interface:

types/user.ts+4−1
export interface User {
id: string;
email: string;
+ name: string;
+ emailVerified: boolean;
+ lastLogin: Date | null;
}

Done! The migration adds email_verified (boolean, default false) and last_login (timestamp, nullable) columns with an index on last_login for query performance.
