chore: translate comments #16
Conversation
WalkthroughMost edits translate comments from Chinese to English without changing behavior. Functional updates include: extending settings sync replaceData to dispatch lastSyncTime, implementing concrete subtodo filtering and visibility logic, and adjusting JWT verification to return the decoded payload with explicit error handling.

Caution
Some comments are outside the diff and can’t be posted inline due to platform limitations.
⚠️ Outside diff range comments (3)
src/app/lib/jwt.ts (3)
20-29: Constrain verification algorithms.Limit accepted algorithms to HS256 (matches signing) and consider small clock tolerance.
- const decoded = jwt.verify(token, JWT_SECRET) as JWTPayload; + const decoded = jwt.verify(token, JWT_SECRET, { + algorithms: ['HS256'], + clockTolerance: 5, // seconds + }) as JWTPayload;
41-53: Do not decode Google ID tokens without verifying the signature.Manual base64 decode skips signature and cert/issuer validation. Replace with google-auth-library verification.
Apply this diff to replace the entire function with a verified, async version:
-import type { GoogleUserInfo, JWTPayload } from '../types/api'; +import type { GoogleUserInfo, JWTPayload } from '../types/api'; +import { OAuth2Client } from 'google-auth-library'; +const oauthClient = new OAuth2Client(); -// Verify Google JWT token -export function verifyGoogleToken(credential: string, googleClientId: string): GoogleUserInfo | null { - // Check Google Client ID configuration - if (!googleClientId || googleClientId.trim() === '') { - console.error('🔴 [JWT] Google Client ID is not configured'); - console.error('🔴 [JWT] Please set GOOGLE_CLIENT_ID or NEXT_PUBLIC_GOOGLE_CLIENT_ID environment variable'); - return null; - } - - try { - // Decode JWT payload (signature should be verified in production) - const payload = JSON.parse(Buffer.from(credential.split('.')[1], 'base64').toString()) as GoogleUserInfo; - - console.log('Token payload:', { - aud: payload.aud, - expected: googleClientId, - exp: payload.exp, - currentTime: Date.now() / 1000, - iss: payload.iss, - sub: payload.sub, - email: payload.email - }); +// Verify Google ID token (signature + claims) +export async function verifyGoogleToken( + credential: string, + googleClientId: string +): Promise<GoogleUserInfo | null> { + if (!googleClientId || googleClientId.trim() === '') { + console.error('🔴 [JWT] Google Client ID is not configured'); + return null; + } + try { + const ticket = await oauthClient.verifyIdToken({ + idToken: credential, + audience: googleClientId, + }); + const payload = ticket.getPayload(); + if (!payload) return null; - // Check if the token has expired - if (payload.exp && payload.exp < Date.now() / 1000) { - throw new Error('Token expired'); - } - - // Validate issuer - if (payload.iss !== 'accounts.google.com' && payload.iss !== 'https://accounts.google.com') { - throw new Error('Invalid issuer'); - } - - // Validate audience (client ID) - supports array and string formats - let isValidAudience = false; - if (Array.isArray(payload.aud)) { - isValidAudience = payload.aud.includes(googleClientId); - } else { - isValidAudience = payload.aud === googleClientId; - } - - if (!isValidAudience) { - console.warn('Audience mismatch (allowing for now):', { - received: payload.aud, - expected: googleClientId - }); - // Temporarily do not throw an error for debugging - // throw new Error('Invalid audience') - } - - return payload; + // Map to our GoogleUserInfo shape + return { + sub: payload.sub ?? '', + email: payload.email ?? '', + name: payload.name ?? '', + picture: payload.picture ?? '', + iss: payload.iss ?? '', + aud: (payload.aud as string) ?? '', + exp: payload.exp ?? 0, + } as GoogleUserInfo; } catch (error) { console.error('Token verification failed:', error); return null; } }Note: Call sites must await this function after the change.
73-79: Do not allow audience mismatches. Fail closed.Permitting mismatched aud weakens security and can enable token replay from other apps.
Apply this diff:
- if (!isValidAudience) { - console.warn('Audience mismatch (allowing for now):', { - received: payload.aud, - expected: googleClientId - }); - // Temporarily do not throw an error for debugging - // throw new Error('Invalid audience') - } + if (!isValidAudience) { + throw new Error('Invalid audience'); + }Also avoid logging PII (email/sub) in payload logs; gate behind a DEBUG flag and mask if needed.
🧹 Nitpick comments (10)
src/app/api/settings/sync/route.ts (1)
11-22: Consider implementing the database operations soon.The TODO comments indicate that actual database operations are temporarily skipped. While this is acceptable for development, ensure this gets implemented before production deployment.
Would you like me to help generate the missing database operation implementation or create a tracking issue for this task?
src/app/componments/todo/TodoTypes.ts (4)
17-23: Simplify and null-safe subtodo status check.Current logic is correct but can be terser and null-safe via optional chaining.
-const hasSubtodosWithStatus = (todo: TodoItem, completed: boolean): boolean => { - if (!todo.subItems || todo.subItems.length === 0) { - return false; - } - return todo.subItems.some((subTodo: SubTodoItem) => subTodo.completed === completed && !subTodo.deleted); -}; +const hasSubtodosWithStatus = (todo: TodoItem, completed: boolean): boolean => + !!todo.subItems?.some((s: SubTodoItem) => s.completed === completed && !s.deleted);
43-59: Comment mismatch with actual logic (some vs all).The SHOW_COMPLETED comment says “all subtodos completed” but code uses a “has at least one completed subtodo” check.
If “all” is intended, change hasSubtodosWithStatus to an every-check; otherwise, update the comment:
-// Show todos with all subtodos completed, or if the main todo is completed +// Show todos with any completed subtodo, or if the main todo itself is completed
64-72: Coalesce originalSubItems to [] and consider memoization.
- If todo.subItems can be undefined, coalesce to [] to satisfy FilteredTodoItem and avoid runtime surprises.
- Optional: memoize getVisibleTodos with reselect to avoid re-creating objects on every render.
- return { + return { ...todo, subItems: filteredSubItems, - originalSubItems: todo.subItems // Save original data + originalSubItems: todo.subItems ?? [] // Save original data };If you want, I can sketch a selector with reselect keyed by filter to reduce recomputation.
25-41: Remove unreachable null check and consolidate filtering infilterSubtodos
TodoItem.subItemsis always defined (SubTodoItem[]), so theif (!subItems…)branch is never taken—drop that guard.- Pull out the common
.filter(s => !s.deleted)into a base array, then switch onfilterto apply only the remaining criteria (completed/!completed) and return that, eliminating duplicated deletion checks.src/app/componments/settings/settingsSyncManagerNew.ts (3)
41-71: Typed payload narrowing is OK; consider guarding unexpected shapes.If server or upstream code ever sends a payload without value, dispatches might receive undefined. A minimal runtime guard reduces risk.
applyOperation(operation: SyncOperation) { const { type, payload } = operation - // Type assertion since we know payload structures for different operation types - const typedPayload = payload as { value: number | boolean | string }; + // Type assertion since we know payload structures for different operation types + const typedPayload = payload as { value?: number | boolean | string }; + if (typedPayload?.value === undefined) { + console.warn('Settings operation missing value:', type, payload) + return + }
83-89: Make sync interval configurable.Hardcoding 10s is fine for now; consider an env/config override to tune without code changes.
-export const settingsSyncManager = new GenericSyncManager( +export const settingsSyncManager = new GenericSyncManager( 'settings', new SettingsAPIAdapter(), new SettingsOperationHandler(), - 10000 // 10-second sync interval for frequent synchronization + Number(import.meta.env.VITE_SETTINGS_SYNC_INTERVAL ?? 10000) // default 10s )
73-80: Add runtime shape validation in replaceData
Guard the incomingdata(typeunknown) with a lightweight type predicate—confirming it has{ settings: SettingsUpdate; lastSyncTime: string }—before callingstore.dispatch(replaceSettings), to prevent dispatching malformed payloads.src/app/api/user/tokens/route.ts (1)
88-94: Minor CORS nit: return 204 for preflight.204 is conventional for OPTIONS with no body.
Apply this diff:
-export async function OPTIONS(request: NextRequest) { - return new NextResponse(null, { - status: 200, - headers: getCorsHeaders(request), - }); -} +export async function OPTIONS(request: NextRequest) { + return new NextResponse(null, { + status: 204, + headers: getCorsHeaders(request), + }); +}src/app/lib/jwt.ts (1)
54-58: Redundant expiry check once signature verification is used.google-auth-library enforces exp; local check becomes unnecessary and risks clock skew divergence.

🛠️ Refactor suggestion
JWT secret handling and expiry: avoid insecure default and prefer library-managed exp.
- Don’t ship a fallback secret; fail fast if JWT_SECRET is unset.
- Prefer jwt.sign({ … }, { expiresIn: '24h' }) over manual iat/exp.
Apply this diff within the selected range to use expiresIn:
export function generateJWT(userInfo: GoogleUserInfo): string {
const payload: JWTPayload = {
sub: userInfo.sub,
email: userInfo.email,
name: userInfo.name,
picture: userInfo.picture,
- iat: Math.floor(Date.now() / 1000),
- exp: Math.floor(Date.now() / 1000) + (24 * 60 * 60) // Expires in 24 hours
};
-
- return jwt.sign(payload, JWT_SECRET, { algorithm: 'HS256' });
+ return jwt.sign(payload, JWT_SECRET, { algorithm: 'HS256', expiresIn: '24h' });
}Additional change outside the selected range (top of file): ensure no default secret and mark server-only.
// add at very top
import 'server-only';
// replace the secret declaration
const JWT_SECRET = process.env.JWT_SECRET;
if (!JWT_SECRET) {
throw new Error('JWT_SECRET is not set');
}🤖 Prompt for AI Agents
In src/app/lib/jwt.ts around lines 6 to 18, the code currently uses a fallback
JWT secret and manually sets iat/exp; update to fail fast if JWT_SECRET is
missing by adding import 'server-only' at the top and replacing any default
secret with const JWT_SECRET = process.env.JWT_SECRET; if (!JWT_SECRET) throw
new Error('JWT_SECRET is not set');, then remove iat and exp from the payload
and call jwt.sign(payload, JWT_SECRET, { algorithm: 'HS256', expiresIn: '24h' })
so the library manages expiration.
