nextjs-task-system/app/page.tsx (1)
11-22: Consider removing console logs in productionThe console logs in the service worker registration (
console.logandconsole.error) may clutter the console in a production environment. It's good practice to remove or properly manage these logs using a logging library that can be disabled or configured for different environments.nextjs-task-system/app/dashboard/page.tsx (4)
36-38: Remove unnecessary console logsThe console log
console.log("que trae sse: " + JSON.stringify(data));is useful for debugging but should be removed or disabled in production code to avoid cluttering the console.
145-151: Avoid usingJSON.stringifyfor state comparisonUsing
JSON.stringifyto compare states can be inefficient and may cause performance issues. Consider using a more efficient method like comparing lengths or using a deep comparison utility.Refactor the comparison:
setFilteredTasks((prevTasks) => { - if (JSON.stringify(prevTasks) !== JSON.stringify(sortedTasks)) { + if (!areTasksEqual(prevTasks, sortedTasks)) { return sortedTasks; } return prevTasks; }); + function areTasksEqual(prevTasks: Task[], nextTasks: Task[]) { + if (prevTasks.length !== nextTasks.length) return false; + return prevTasks.every((task, index) => task.id === nextTasks[index].id); + }
153-177: Maintain consistency in asynchronous code handlingIn
handleAddTask, bothasync/awaitand.then()syntax are used together, which can be confusing. Stick to one approach for readability.Refactored using
async/await:const handleAddTask = async (newTask: Task) => { try { const response = await axios.post("http://localhost:3000/api/tasks", newTask, { headers: { Authorization: `Bearer ${token}`, }, }); const { assigned_name } = response.data; const completeTask: Task = { ...newTask, assigned_name, }; setTasks([...tasks, completeTask]); setIsModalOpen(false); alert("Tarea registrada exitosamente"); } catch (error) { console.error("Error al crear tarea:", error); } };
179-198: Maintain consistency in asynchronous code handlingSimilarly, in
handleUpdateTask, consistently useasync/awaitinstead of mixing with.then().Refactored code:
const handleUpdateTask = async (newTask: Task) => { try { await axios.put("http://localhost:3000/api/tasks", newTask, { headers: { Authorization: `Bearer ${token}`, }, }); // Update the local task list setTasks((prevTasks) => prevTasks.map((task) => (task.id === newTask.id ? newTask : task)) ); alert("Tarea actualizada exitosamente"); } catch (error) { console.error("Error al actualizar tarea:", error); } };nextjs-task-system/pages/api/tasks/index.ts (3)
26-36: Redundant Token Verification ingetTasksFunctionIn the
getTasksfunction, you're extracting and verifying the token again, even though theprotectRoutemiddleware should have already handled token verification and attacheduserIdto thereqobject. This redundancy leads to unnecessary code duplication.Consider removing the redundant token extraction and verification to streamline the code. Here's how you can refactor:
- const token = req.headers["authorization"]?.split(" ")[1]; // El formato es "Bearer <token>" - if (!token) { - return res.status(401).json({ message: "Unauthorized: No token provided" }); - } - const decoded = verifyToken(token); - if (!decoded) { - return res.status(401).json({ message: "Unauthorized: Invalid token" }); - }Since
req.userIdis set by the middleware, you can directly use it in your queries.
178-193: Inconsistent Language in Error MessagesThe error message "Faltan campos requeridos" is in Spanish, while other error messages in the API are in English.
For consistency and better user experience, standardize all error messages to a single language. Consider updating the message as follows:
- return res.status(400).json({ message: "Faltan campos requeridos" }); + return res.status(400).json({ message: "Missing required fields" });Ensure that all error messages throughout the API use the chosen language consistently.
398-399: Duplicate Error Handling indeleteTaskFunctionIn the
deleteTaskfunction, the error message "Task not found" is returned twice—once when the task doesn't exist and again if the deletion affects zero rows.To avoid confusion, modify the second error message to indicate that the task may have already been deleted:
if (this.changes === 0) { return res .status(404) - .json({ error: "Task not found or already deleted" }); + .json({ error: "Task not found or may have been already deleted" }); }This provides clearer information to the client about the operation's outcome.
nextjs-task-system/types/next.d.ts (1)
3-7: Correct Module Augmentation forNextApiRequestInterfaceWhen extending the
NextApiRequestinterface, ensure that the module augmentation is properly applied to avoid type conflicts.Modify the import statement and confirm that the augmentation merges correctly:
-import { NextApiRequest } from "next"; +import type { NextApiRequest } from "next"; declare module "next" { interface NextApiRequest { userId?: number; } }This change ensures that TypeScript recognizes the augmentation without conflicts.
nextjs-task-system/utils/init.ts (1)
5-8: Add Error Handling toinitDBFunctionThe
initDBfunction callsinitializeDB()but doesn't handle potential errors during database initialization.Implement error handling to catch and log any initialization errors:
export const initDB = () => { - initializeDB(); - console.log("Database initialized."); + initializeDB() + .then(() => { + console.log("Database initialized."); + }) + .catch((err) => { + console.error("Database initialization failed:", err); + }); };Ensure that
initializeDB()returns a promise. If it doesn't, consider refactoring it to support asynchronous operations.nextjs-task-system/components/FloatingButton.tsx (2)
9-9: Translate comment to English for consistency.Replace the Spanish comment with English:
- onClick={onPress} // Aquí manejarás la acción de agregar tarea + onClick={onPress} // Handle add task action here
8-13: Enhance button accessibility.The button should have an aria-label to improve accessibility for screen readers.
<button onClick={onPress} className="flex h-14 w-14 items-center justify-center rounded-full bg-blue-500 text-white shadow-lg hover:bg-blue-600 focus:outline-none focus:ring-4 focus:ring-blue-300" + aria-label="Add new item" > <span className="text-2xl font-bold">+</span> </button>nextjs-task-system/types/index.ts (2)
2-7: Enhance User interface with additional fields and validation.The User interface could be improved with additional fields and validation constraints.
export interface User { id?: number; username: string; password: string; - role: string; + email: string; + role: 'admin' | 'user'; + created_at?: string; + last_login?: string; }
23-28: Enhance Group interface with additional metadata.The Group interface could be improved with additional fields for better group management.
export interface Group { id?: number; name: string; user_ids?: number[]; users: User[]; + created_at: string; + updated_at?: string; + description?: string; + created_by: number; // User ID of group creator }nextjs-task-system/database/auth.ts (1)
8-10: Consider adding password complexity validationWhile the password hashing implementation is correct, consider adding password complexity validation before hashing.
Example implementation:
export const hashPassword = (password: string) => { const minLength = 8; if (password.length < minLength) { throw new Error(`Password must be at least ${minLength} characters long`); } return bcrypt.hashSync(password, 10); };nextjs-task-system/app/layout.tsx (1)
31-36: Consider adding error boundary around AuthProviderWhile the authentication provider setup looks good, consider adding an error boundary to handle authentication-related errors gracefully.
Example implementation:
import { ErrorBoundary } from 'react-error-boundary'; function ErrorFallback({error}) { return ( <div role="alert"> <p>Something went wrong with authentication:</p> <pre>{error.message}</pre> </div> ) } // In your layout: <ErrorBoundary FallbackComponent={ErrorFallback}> <AuthProvider> <NavBar /> {children} </AuthProvider> </ErrorBoundary>nextjs-task-system/components/Tasks/ConfirmDelete.tsx (1)
18-40: Enhance accessibility and internationalizationSeveral improvements can be made:
- Add ARIA labels for better accessibility
- Extract text content for internationalization
- Add keyboard handling for modal interactions
<Modal show={isOpen} onClose={onClose}> - <Modal.Header>Confirmar Eliminación</Modal.Header> + <Modal.Header aria-label="Delete confirmation dialog"> + {t('modal.delete.title')} + </Modal.Header> <Modal.Body> - <p className="text-gray-700"> - ¿Estás seguro de que deseas eliminar esta tarea? Esta acción no se - puede deshacer. + <p className="text-gray-700" role="alert"> + {t('modal.delete.confirmation')} </p> </Modal.Body>nextjs-task-system/components/NavBar.tsx (1)
15-52: Improve accessibility and mobile responsivenessThe navigation bar needs several improvements:
- Add ARIA labels and roles
- Ensure proper keyboard navigation
- Verify mobile menu functionality
- <Navbar fluid className="bg-gray-100 dark:bg-gray-800"> + <Navbar fluid className="bg-gray-100 dark:bg-gray-800" role="navigation" aria-label="Main navigation"> <Navbar.Brand> - <Link href="/dashboard"> + <Link href="/dashboard" aria-label="Go to dashboard">nextjs-task-system/pages/api/auth/login.ts (1)
15-15: Translate Spanish comments to EnglishFor consistency and maintainability, all comments should be in English.
- // Buscar el usuario por su nombre de usuario + // Find user by username - // Generar un token JWT + // Generate JWT token - // Aquí envías los datos del usuario + // Send user dataAlso applies to: 38-38, 47-47
nextjs-task-system/components/users/Card.tsx (1)
8-18: Improve type safety and prop validationThe component's props interface could be more strictly typed.
interface CustomCardUserProps { usuario: User; token: string | null; user: User | undefined; openDeleteModal: (userId: string) => void; } export function CustomCardUser({ usuario, token, user, openDeleteModal, }: CustomCardUserProps) {nextjs-task-system/components/groups/GroupDetails.tsx (2)
1-8: Consider adding prop validation and documentation.The props interface is clean, but could benefit from JSDoc documentation to improve maintainability.
+/** + * Props for the GroupDetails component + * @property {Group} group - The group object containing name and users + * @property {boolean} isOpen - Controls modal visibility + * @property {() => void} onClose - Callback function when modal closes + */ interface GroupDetailsProps { group: Group; isOpen: boolean; onClose: () => void; }
22-24: Consider internationalization for hardcoded strings.The component contains hardcoded Spanish text that should be internationalized for better maintainability and localization support.
Consider using a translation library or creating a constants file for managing text strings.
nextjs-task-system/database/task.ts (1)
6-12: Implement proper database connection management.The database connection should be properly managed with error handling and cleanup.
Consider implementing a connection pool or proper cleanup mechanism:
- Add a closeDB function for proper cleanup
- Implement connection pooling for better performance
- Add retry logic for connection failures
- Consider implementing a health check mechanism
Would you like me to provide an implementation for these improvements?
nextjs-task-system/pages/api/refresh.ts (1)
59-65: Implement connection tracking and resource cleanupThe current implementation might lead to memory leaks with multiple connections.
Consider implementing connection tracking:
+const activeConnections = new Set(); + export default function handler(req: NextApiRequest, res: NextApiResponse) { + const connectionId = Date.now().toString(); + activeConnections.add(connectionId); + // ... existing code ... + req.on("close", () => { console.log("Cliente desconectado"); clearInterval(intervalId); + activeConnections.delete(connectionId); res.end(); }); + + // Implement max connections limit + if (activeConnections.size > MAX_CONNECTIONS) { + res.status(503).json({ error: 'Too many connections' }); + return; + } }nextjs-task-system/components/Tasks/Filtrado.tsx (2)
8-9: Consider standardizing comment languageThe comments are mixing English and Spanish ("Nuevo"). Consider standardizing all comments to English for consistency across the codebase.
- setSortOrder: React.Dispatch<React.SetStateAction<string>>; // Nuevo prop para el ordenamiento - sortOrder: string; // Nuevo estado para el ordenamiento + setSortOrder: React.Dispatch<React.SetStateAction<string>>; // New prop for sorting + sortOrder: string; // New state for sorting
25-105: Consider extracting filter sections into separate componentsThe component has multiple similar filter sections that could be extracted into reusable components to improve maintainability and reduce code duplication.
Consider creating a reusable
FilterSectioncomponent:interface FilterSectionProps { id: string; label: string; value: string; onChange: (value: string) => void; options?: Array<{value: string, label: string}>; type?: 'select' | 'input'; } function FilterSection({id, label, value, onChange, options, type = 'select'}: FilterSectionProps) { return ( <div className="flex flex-col"> <label htmlFor={id} className="mb-1 text-sm font-medium text-gray-600 dark:text-gray-300" > {label} </label> {type === 'select' ? ( <select id={id} className="rounded-md border border-gray-300 bg-gray-50 p-2 dark:border-gray-600 dark:bg-gray-700 dark:text-white" value={value} onChange={(e) => onChange(e.target.value)} > {options?.map(opt => ( <option key={opt.value} value={opt.value}>{opt.label}</option> ))} </select> ) : ( <input id={id} type="text" className="rounded-md border border-gray-300 bg-gray-50 p-2 dark:border-gray-600 dark:bg-gray-700 dark:text-white" value={value} onChange={(e) => onChange(e.target.value)} /> )} </div> ); }nextjs-task-system/components/Tasks/Card.tsx (1)
24-24: Remove console.log statementDebug statements should not be present in production code.
- console.log("que trae task: " + task);nextjs-task-system/components/Tasks/TaskDetails.tsx (1)
78-91: Standardize date formattingDates are displayed without consistent formatting, which could lead to confusion.

1-24: Verify service worker registration across the application
Ensure that the service worker is properly registered before using this hook.
✅ Verification successful
Let me check the content of the service worker file to understand the registration setup better.
Service Worker is properly registered and implemented
The service worker is correctly registered in app/page.tsx and properly implemented in public/sw.js with the necessary event listeners for push notifications. The useNotification hook's implementation aligns well with this setup.
- ✓ Service worker registration in
app/page.tsx - ✓ Push notification handling in
public/sw.js - ✓ Notification click events properly managed
- ✓ Hook implementation compatible with the service worker setup

Enhance security of role-based rendering
While client-side role checking is convenient, it should be complemented with server-side validation to prevent unauthorized access.
✅ Verification successful
Server-side role validation is properly implemented
The codebase has robust server-side role validation through:
- A middleware (
protectRoute) that verifies tokens and roles before allowing access to protected routes - API routes using the middleware with required roles (e.g.,
protectRoute(createTask, "admin")) - Database-level role checks for additional security
The client-side role check in NavBar.tsx is appropriately complemented with server-side validation, making it secure.

🛠️ Refactor suggestion
Reconsider including sw.js in TypeScript compilation
Service workers should typically remain as pure JavaScript files. Including them in TypeScript compilation is unnecessary and might cause issues:
- Service workers run in a different context than your application
- TypeScript compilation isn't needed for files in the
public/directory - This might interfere with Next.js's handling of service workers
Consider removing "public/sw.js" from the include array and instead:
- Add type checking through JSDoc comments if needed
- Use a separate build process for the service worker if TypeScript is required

💡 Codebase verification
Service worker setup needs security improvements
The service worker implementation and registration are present but require security enhancements:
- Service worker is correctly placed in
public/sw.jsand properly registered inpage.tsx - Basic push notification functionality is implemented
- However, missing critical security configurations:
- No Content Security Policy headers defined in
next.config.mjs - No HTTPS enforcement in middleware
- No Service-Worker-Allowed header configuration
- No Content Security Policy headers defined in
Recommendations:
- Remove
public/sw.jsfromtsconfig.jsonas it's pure JavaScript and doesn't need TypeScript compilation - Add security headers in
next.config.mjs:{ headers: () => [{ source: '/sw.js', headers: [ { key: 'Service-Worker-Allowed', value: '/' }, { key: 'Content-Security-Policy', value: "default-src 'self'" } ] }] }
- Ensure HTTPS is enforced in production environment

Handle cases where the authentication status is unclear
In the authentication check, if token is present but isAuthenticated is false, the user will remain on the loading screen without redirection. Consider adding an else clause to handle this scenario, ensuring the user is directed appropriately.

useEffect(() => {
if (isAuthenticated && token) {
router.push("/dashboard");
} else {
router.push("/login");
}

Extend NextApiRequest to include userId property
Adding userId to req may cause TypeScript errors since NextApiRequest doesn't include userId by default. Extend the NextApiRequest interface to define the userId property.
Add a new TypeScript declaration file (e.g., next-env.d.ts):
// next-env.d.ts
import { NextApiRequest } from "next";
declare module "next" {
interface NextApiRequest {
userId?: number;
}

🛠️ Refactor suggestion
Ensure consistent asynchronous handling in middleware
The protectRoute function calls handler(req, res) synchronously when requiredRole is not provided, but calls it asynchronously within a database callback when requiredRole is specified. This inconsistency can lead to unexpected behavior.
Refactor the middleware to always handle handler(req, res) asynchronously:
export const protectRoute = (handler: any, requiredRole?: string) => {
return async (req: NextApiRequest, res: NextApiResponse) => {
// ... existing code ...
// Always proceed asynchronously
const proceed = () => {
req.userId = userId;
return handler(req, res);
};
if (!requiredRole) {
return proceed();
}
// Verify role if required
db.get(
"SELECT role FROM users WHERE id = ?",
[userId],
(err, user: User) => {
if (err) {
return res.status(500).json({ error: "Error checking user role" });
}
if (!user || user.role !== requiredRole) {
return res
.status(403)
.json({ error: "Forbidden: Insufficient permissions" });
}
return proceed();
}
);
};

Thank you for your submission! Here's a detailed review of your implementation:
👍 Strengths:
-
SQL Client Implementation
- Good use of the SQL client
- Clean database interactions
- Well-structured queries
-
Project Structure
- Clear and organized folder structure
- Good separation of concerns
- Components are well-modularized
-
Custom Hooks
- Nice implementation of custom useSSE hook
- Shows good understanding of React hooks pattern
🔧 Areas for Improvement:
-
Next.js Features Utilization
- The application is entirely client-side rendered (all pages use 'use client')
- Missing out on Next.js 13+ App Router benefits:
- Server Components
- Built-in data fetching
- Route handlers
- Layout system
- Consider migrating to App Router for better performance and SEO
-
State Management
- Heavy reliance on useState hooks
- Consider using:
- useReducer for complex state
- React Context for global state
- State management libraries if needed
-
Data Validation
- More robust validation needed throughout the application
- Add type checking for API responses
- Implement proper error boundaries
- Consider using Zod or similar for runtime type validation
-
SSE Implementation
- Current SSE usage might be overengineered
- Consider simpler solutions like:
- Regular REST endpoints
- Polling for non-critical updates
- SSE only for specific real-time features
-
Environment Configuration
- Move hardcoded URLs to environment variables
- Implement proper configuration management
Recommendations for Next Steps:
- Implement Server-Side Rendering where appropriate
- Add comprehensive error handling
- Implement proper type validation
- Consider simplifying the real-time update mechanism
- Add loading states and better error UX
Overall, the code shows good understanding of React fundamentals but could benefit from leveraging more Next.js features and modern best practices.

@riveros0302 Hi! Thanks for your work on this feature. I have one important observation about best practices:
The hardcoded URLs (http://localhost:3000) should be moved to environment variables. This is important because:
- It makes the application more configurable across different environments (development, staging, production)
- It follows security best practices by not exposing specific URLs in the codebase
- It makes the code more maintainable - if we need to change the API URL, we only need to change it in one place
To fix this:
- Create a
.env.localfile in the project root - Add: NEXT_PUBLIC_API_URL=http://localhost:3000
- Replace all instances of "http://localhost:3000" with ${process.env.NEXT_PUBLIC_API_URL}
Example:
// Before
const response = await axios.get("http://localhost:3000/api/tasks"...)
// After
const response = await axios.get(`${process.env.NEXT_PUBLIC_API_URL}/api/tasks`...)| @@ -0,0 +1,271 @@ | |||

@riveros0302
There's a potential issue with the file imports that could cause problems on different operating systems:
The import path "@/components/tasks/Card" vs the actual file path "@/components/Tasks/Card"
differs in case sensitivity (lowercase 'tasks' vs uppercase 'Tasks').
While this might work on macOS and Windows (which are case-insensitive by default), it could break when:
- Deploying to Linux servers (which are case-sensitive)
- Working with different team members using different OS configurations
- Using certain build tools or CI/CD pipelines
To fix this:
- Make sure the import path exactly matches the folder structure
- Choose a consistent naming convention for folders (either PascalCase or lowercase)
- Update all related imports accordingly
Example:
// If the folder is "Tasks", use:
import { CustomCard } from "@/components/Tasks/Card";
// If the folder is "tasks", use:
import { CustomCard } from "@/components/tasks/Card";Please ensure all imports match the actual file system case exactly.

@riveros0302
There's a potential issue with the order of your function declarations. Currently, applyFilters is used in the useEffect before it's defined, which relies on function hoisting. While this works, it's not a best practice because:
- It makes the code harder to read and maintain
- It can lead to confusion about scope and availability
- It doesn't follow the principle of declaring things before using them
You have two options to fix this:
Option 1 - Move the function declaration before its usage:
const applyFilters = () => {
// ... function implementation ...
};
useEffect(() => {
applyFilters();
}, [filterState, filterUser, filterPriority, tasks]);Option 2 - Use a named function declaration:
function applyFilters() {
// ... function implementation ...
}
useEffect(() => {
applyFilters();
}, [filterState, filterUser, filterPriority, tasks]);Please reorganize the code to follow one of these patterns for better code organization and readability.

@riveros0302 same to this function call as above

There's an important React hooks dependency issue that could lead to stale closure problems:
The current useEffect depends on sortTasks, but it's not included in the dependency array. This means the effect might use an outdated version of the function, leading to unexpected behaviors.
To fix this, you should either:
- Move the sortTasks function inside the useEffect (preferred if the function is only used here):
useEffect(() => {
function sortTasks() {
if (!sortOrder) return;
let sortedTasks = [...filteredTasks];
if (sortOrder === "due_date") {
sortedTasks.sort((a, b) => {
// ... sorting logic ...
});
}
// ... rest of sorting logic ...
setFilteredTasks((prevTasks) => {
if (JSON.stringify(prevTasks) !== JSON.stringify(sortedTasks)) {
return sortedTasks;
}
return prevTasks;
});
}
sortTasks();
}, [sortOrder, filteredTasks]);- Or use useCallback to memoize the function (better if sortTasks is used in multiple places):
const sortTasks = useCallback(() => {
if (!sortOrder) return;
let sortedTasks = [...filteredTasks];
// ... rest of sorting logic ...
setFilteredTasks((prevTasks) => {
if (JSON.stringify(prevTasks) !== JSON.stringify(sortedTasks)) {
return sortedTasks;
}
return prevTasks;
});
}, [sortOrder, filteredTasks]);
useEffect(() => {
sortTasks();
}, [sortTasks]);This ensures that:
- The effect always has access to the latest version of the function
- We avoid stale closure issues
- We properly follow React's hooks dependency rules
- The code is more predictable and maintainable
Please implement one of these solutions based on your specific use case.

There was a problem hiding this comment.
There's a critical issue with the SSE data handling that's causing runtime errors. The current implementation doesn't validate the SSE event data before using it, which leads to type errors when assigning invalid data to the tasks state.
To fix this, we should:
- Validate the SSE event data
- Type the data properly
Here's how to improve it:
// Add type validation helper
const isTaskArray = (data: unknown): data is Task[] => {
return Array.isArray(data) && data.every(item =>
typeof item === 'object' &&
item !== null &&
'id' in item // add other required Task properties
);
};
// Use the validation in your component
const data = useSSE("http://localhost:3000/api/refresh");
useEffect(() => {
if (data) {
try {
if (isTaskArray(data)) {
setTasks(data);
} else {
console.error("Received invalid data format from SSE");
}
} catch (error) {
console.error("Error processing SSE data:", error);
}
}
}, [data]);This improves the code by:
- Adding type safety to prevent runtime errors
- Validating data structure before using it
- Providing proper error handling
- Making the code more robust and maintainable

I noticed you're using Server-Sent Events (SSE) to maintain dashboard state synchronization. While SSE can be useful for real-time updates, the current implementation might be overengineered for this use case. Here's why:
-
Performance Concerns:
- SSE creates a persistent connection that constantly updates the state
- Each update triggers a re-render of your entire dashboard
- This can lead to unnecessary component re-renders and potential performance issues
-
Data Usage:
- Constant polling uses more bandwidth than necessary
Alternative Approaches:
- Regular REST Endpoint (Simpler Solution)
- SSE with Specific Events (If real-time is really needed):
const handleSSEMessage = (event: MessageEvent) => {
switch (event.type) {
case 'taskCreated':
case 'taskUpdated':
case 'taskDeleted':
getTasks(); // Only refresh when something actually changed
break;
}
};
Questions to consider:
- Do SSE is the right solution for fetching users tasks?
- Are we optimizing for the right metrics (performance vs real-time updates)?
I recommend simplifying this to use regular REST endpoints
