Ensure PostgreSQL is running and configure the connection in `.env.local` + +2. Run database migrations to create the schema: ```bash npm run migrate-This should also generate the client for the project. In case you encounter an issue, run the following scripts.
+3. Generate Prisma client (if not generated by migrations):npm run generate-And finally, I have some dummy data you can seed if you wish to do it.

40-49: Refactor groups creation for better maintainabilitySimilar to the users creation, consider refactoring the groups creation to reduce duplication and improve maintainability.
+const defaultGroups = ["Team developer", "Team QA"]; + +const groups = await Promise.all( + defaultGroups.map((groupName) => + prisma.groups.create({ + data: { name: groupName }, + }) + ) +);
50-65: Add type safety to group members associationConsider adding TypeScript interfaces for better type safety and code documentation.
+interface GroupMember { + userId: string; + groupId: string; +} + +const groupAssignments: GroupMember[] = [ + { userId: users[0].id, groupId: groups[0].id }, + { userId: users[1].id, groupId: groups[0].id }, + { userId: users[2].id, groupId: groups[1].id }, +]; + const usersGroups = await prisma.groupMembers.createMany({ - data: [ - { - userId: user.id, - groupId: group1.id, - }, - // ... other assignments - ], + data: groupAssignments, });
97-105: Enhance error handling and loggingConsider improving the error handling with better error messages and cleanup procedures.
main() .then(async () => { await prisma.$disconnect(); + console.log('Database seeding completed successfully'); }) .catch(async (error) => { - console.error(error); + console.error('Failed to seed database:', error); await prisma.$disconnect(); + // Attempt to clean up any partially created data + try { + // Add cleanup logic here if needed + console.log('Cleanup completed'); + } catch (cleanupError) { + console.error('Failed to clean up:', cleanupError); + } process.exit(1); });nextjs-task-system/prisma/migrations/20241212202419_initial_migration/migration.sql (3)
4-6: Consider expanding TaskStatus enum for better workflow managementThe current status options (PENDING, IN_PROGRESS, COMPLETED) are good starting points, but consider adding more granular statuses to better reflect real-world task workflows:
- BLOCKED: For tasks waiting on dependencies
- REVIEW: For tasks requiring approval
- ON_HOLD: For temporarily suspended tasks
24-31: Enhance groups table with additional management fieldsConsider adding these fields to improve group management capabilities:
description: For group detailsmax_members: To limit group sizeowner_id: To track group ownershipis_active: To manage group stateCREATE TABLE "groups" ( "id" TEXT NOT NULL, "name" TEXT NOT NULL, + "description" TEXT, + "max_members" INTEGER, + "owner_id" TEXT NOT NULL, + "is_active" BOOLEAN NOT NULL DEFAULT true, "created_at" TIMESTAMP(3) NOT NULL DEFAULT CURRENT_TIMESTAMP, "updated_at" TIMESTAMP(3) NOT NULL, CONSTRAINT "groups_pkey" PRIMARY KEY ("id") ); +ALTER TABLE "groups" ADD CONSTRAINT "groups_owner_id_fkey" + FOREIGN KEY ("owner_id") REFERENCES "users"("id") + ON DELETE RESTRICT ON UPDATE CASCADE;
58-67: Enhance comment system for better collaborationConsider adding:
- Parent-child relationship for threaded discussions
- Edit history tracking
- Comment type (e.g., general, status update, review)
CREATE TABLE "comments" ( "id" TEXT NOT NULL, "task_id" TEXT NOT NULL, "user_id" TEXT NOT NULL, "comment" TEXT NOT NULL, + "parent_id" TEXT, + "comment_type" VARCHAR(50) DEFAULT 'general', + "is_edited" BOOLEAN DEFAULT FALSE, "created_at" TIMESTAMP(3) NOT NULL DEFAULT CURRENT_TIMESTAMP, "updated_at" TIMESTAMP(3) NOT NULL, CONSTRAINT "comments_pkey" PRIMARY KEY ("id") ); +ALTER TABLE "comments" ADD CONSTRAINT "comments_parent_id_fkey" + FOREIGN KEY ("parent_id") REFERENCES "comments"("id") + ON DELETE CASCADE ON UPDATE CASCADE;nextjs-task-system/prisma/schema.prisma (2)
62-63: Standardize foreign key field naming to snake_caseThe foreign key fields
groupIdanduserIdin theGroupMembersmodel use camelCase naming conventions, while other models use snake_case (e.g.,group_id,user_id). For consistency across the schema, consider renaming these fields togroup_idanduser_id.Apply this diff to rename the fields:
model GroupMembers { - groupId String - userId String + group_id String + user_id String user Users @relation(fields: [userId], references: [id]) group Groups @relation(fields: [groupId], references: [id])Also, update the relation definitions accordingly:
user Users @relation(fields: [userId], references: [id]) group Groups @relation(fields: [groupId], references: [id]) + user Users @relation(fields: [user_id], references: [id]) + group Groups @relation(fields: [group_id], references: [id])
75-75: Renameassigned_tofield touser_idfor clarityTo maintain consistency with other models and clearly indicate that this field is a foreign key referencing the
Usersmodel, consider renamingassigned_totouser_id.Apply this diff to rename the field:
model Tasks { - assigned_to String + user_id StringUpdate the relation definition accordingly:
user Users @relation(fields: [assigned_to], references: [id]) + user Users @relation(fields: [user_id], references: [id])nextjs-task-system/app/(dashboard)/teams/create/page.tsx (1)
6-8: Enhance layout and responsivenessThe flex container lacks proper styling for responsive design. Consider adding padding, width constraints, and responsive classes.
- <div className="flex"> + <div className="flex w-full max-w-4xl mx-auto p-4 sm:p-6 lg:p-8">nextjs-task-system/app/page.tsx (1)
6-9: Improve layout and dark mode toggle placementThe current layout could be enhanced for better user experience.
- <main className="flex min-h-screen items-center justify-center gap-2 dark:bg-gray-800"> - <DarkThemeToggle /> - <LoginForm /> + <main className="min-h-screen bg-gray-50 dark:bg-gray-900"> + <div className="absolute top-4 right-4"> + <DarkThemeToggle /> + </div> + <div className="flex min-h-screen items-center justify-center p-4"> + <div className="w-full max-w-md"> + <LoginForm /> + </div> + </div>nextjs-task-system/app/(dashboard)/dashboard/[groupId]/page.tsx (1)
4-11: Add error handling and loading statesWhile the component structure is clean, consider adding:
- Error boundary to handle potential failures in GroupDashboard
- Loading state while group data is being fetched
- Type validation for groupId parameter
const GroupDashboardPage = ({ params }: { params: { groupId: string } }) => { + if (!params.groupId) { + return <div>Invalid group ID</div>; + } + return ( - <div className="flex"> + <ErrorBoundary fallback={<div>Something went wrong</div>}> + <Suspense fallback={<div>Loading...</div>}> <GroupDashboard groupId={params.groupId} /> - </div> + </Suspense> + </ErrorBoundary> ) }nextjs-task-system/app/api/v1/groupmember/[groupId]/route.ts (2)
8-8: Remove debug console.log statementRemove the console.log statement as it's not suitable for production code.
- console.log(groupId);
1-19: Consider implementing rate limitingTo prevent abuse, consider implementing rate limiting for these API endpoints.
You can use a package like
@upstash/ratelimitwith Redis:import { Ratelimit } from '@upstash/ratelimit' import { Redis } from '@upstash/redis' const ratelimit = new Ratelimit({ redis: Redis.fromEnv(), limiter: Ratelimit.slidingWindow(20, '1 m'), }) // In your route handler: const identifier = request.ip // or session.user.id const { success } = await ratelimit.limit(identifier) if (!success) { return Response.json( { error: 'Too many requests' }, { status: 429 } ) }nextjs-task-system/app/types.d.ts (2)
1-2: Consider using an enum instead of union typesFor better type safety and maintainability, consider using TypeScript enums for Priority and TaskStatus.
export enum Priority { LOW = 'LOW', MEDIUM = 'MEDIUM', HIGH = 'HIGH' } export enum TaskStatus { PENDING = 'PENDING', IN_PROGRESS = 'IN_PROGRESS', COMPLETED = 'COMPLETED' }
22-27: Add timestamps to Comment typeComments should track creation and update times for better audit trails.
/** * Represents a comment on a task */ export type Comment = { id: string comment: string task_id: string user_id: string created_at: Date updated_at: Date }nextjs-task-system/app/lib/authMiddleware.ts (1)
2-2: Remove commented out codeThe commented out jwt import is not being used and should be removed to maintain clean code.
nextjs-task-system/app/(dashboard)/task/page.tsx (1)
31-40: Simplify the role check logicThe nested if-else structure can be simplified for better readability.
useEffect(() => { - if (!user) { - return; - } else { - if (user?.role !== "ADMIN") { - router.push("/dashboard"); - return; - } + if (user && user.role !== "ADMIN") { + router.push("/dashboard"); } }, [user]);nextjs-task-system/tests/api/tasks/route.test.ts (1)
18-26: Validate task data structureAdd type checking for the mock data to ensure it matches the expected schema.
+interface TaskInput { + title: string; + description: string; + assigned_to: string; + status: 'pending' | 'in_progress' | 'completed'; + group_id: number; + due_date: string; + priority: 'low' | 'medium' | 'high'; +} - const mockData = { + const mockData: TaskInput = { title: 'Test Task', description: 'Description', assigned_to: 'user123', status: 'pending', group_id: 1, due_date: '2024-12-31', priority: 'high', };nextjs-task-system/app/components/CreateTeam.tsx (1)
1-50: Consider separating data fetching logic from UIThe component mixes UI rendering with data fetching logic. Consider implementing a more maintainable architecture.
Suggested approach:
- Create a custom hook for team creation logic:
// hooks/useCreateTeam.ts import { useState } from 'react' import { useRouter } from 'next/navigation' interface CreateTeamInput { name: string } export const useCreateTeam = () => { const [isLoading, setIsLoading] = useState(false) const [error, setError] = useState('') const router = useRouter() const createTeam = async (input: CreateTeamInput) => { setIsLoading(true) setError('') try { const response = await fetch('/api/v1/groups', { method: 'POST', headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ name: input.name }) }) if (!response.ok) { const data = await response.json() throw new Error(data.message || 'Failed to create team') } await router.push('/teams') } catch (err) { setError(err.message) throw err } finally { setIsLoading(false) } } return { createTeam, isLoading, error } }
- Simplify the component to focus on UI:
import { useCreateTeam } from '@/hooks/useCreateTeam' export const CreateTeam = () => { const [groupName, setGroupName] = useState('') const { createTeam, isLoading, error } = useCreateTeam() const handleSubmit = async (e: React.FormEvent<HTMLFormElement>) => { e.preventDefault() if (groupName.trim() === '') { setError('The team name is required') return } try { await createTeam({ name: groupName.trim() }) } catch (err) { // Error is handled by the hook } } // ... rest of the component }nextjs-task-system/app/components/AddComments.tsx (1)
1-8: Add prop validation and error handlingConsider enhancing the component's robustness:
- Add prop validation using PropTypes or Zod
- Implement error boundaries to gracefully handle rendering failures
nextjs-task-system/app/components/LoginForm.tsx (1)
7-11: Improve form state managementConsider enhancing the form implementation:
- Use a form management library (e.g., React Hook Form)
- Add loading state
- Implement proper validation
+import { useForm } from 'react-hook-form'; +import { z } from 'zod'; +import { zodResolver } from '@hookform/resolvers/zod'; + +const loginSchema = z.object({ + email: z.string().email('Invalid email address'), + password: z.string().min(8, 'Password must be at least 8 characters'), +}); + export const LoginForm = () => { - const [email, setEmail] = useState(""); - const [password, setPassword] = useState(""); const [error, setError] = useState(""); + const [isLoading, setIsLoading] = useState(false); const router = useRouter(); + + const { + register, + handleSubmit, + formState: { errors }, + } = useForm({ + resolver: zodResolver(loginSchema), + });nextjs-task-system/app/components/TeamsPage.tsx (1)
7-20: Enhance type definitions and add documentationConsider improving the type definitions:
- Add readonly modifiers for immutable properties
- Add JSDoc documentation
- Consider optional properties
- Add validation rules
+/** + * Represents a team or department group + */ interface Group { - id: string; - name: string; + readonly id: string; + readonly name: string; + readonly description?: string; + readonly createdAt: Date; } +/** + * Represents a user in the system + */ interface User { - id: string; - email: string; - role: string; + readonly id: string; + readonly email: string; + readonly role: 'ADMIN' | 'USER'; + readonly name?: string; + readonly lastLogin?: Date; } +/** + * Represents a user's association with a group + */ interface UserGroup { - group: Group; + readonly group: Group; + readonly role?: 'MEMBER' | 'LEADER'; + readonly joinedAt: Date; }nextjs-task-system/app/components/TaskModal.tsx (2)
33-33: Remove console.log statementRemove debugging console.log statement before production deployment.
- console.log(dayjs(task.due_date).utcOffset(8))
51-56: Add aria-label to status selectImprove accessibility by adding an aria-label to the status select element.
- <Select id="status" value={task?.status} onChange={handleStatusChange} className="w-1/2"> + <Select + id="status" + value={task?.status} + onChange={handleStatusChange} + className="w-1/2" + aria-label="Task status" + >nextjs-task-system/app/components/SideNavBar.tsx (1)
65-77: Add client-side role validationWhile server-side validation is crucial, adding client-side validation improves UX by preventing unauthorized access attempts.
+ const isAdmin = user?.role === "ADMIN"; + + useEffect(() => { + if (!isAdmin && window.location.pathname.match(/\/(teams\/create|users|task)$/)) { + router.push('/dashboard'); + } + }, [isAdmin, router]); - {user?.role === "ADMIN" && ( + {isAdmin && (nextjs-task-system/app/components/GroupDashboard.tsx (2)
69-71: Remove commented codeRemove commented out useEffect block as it's no longer needed.
- // useEffect(() => { - // fetchTasks() - // }, [showModal])
58-58: Remove console.log statementsRemove debugging console.log statements before production deployment.
- console.log(data) - console.log(data.tasks)Also applies to: 65-65
nextjs-task-system/app/components/CreateTaskForm.tsx (2)
7-19: Consider moving types to a separate file for better reusability.The types defined here might be used across different components. Consider moving them to a separate types file (e.g.,
types/task.ts) to promote code reuse and maintainability.
23-31: Consider consolidating form state management.Multiple useState hooks could be consolidated into a single form state object to reduce complexity and potential re-renders.
Example refactor:
- const [title, setTitle] = useState('') - const [description, setDescription] = useState('') - const [status, setStatus] = useState<TaskStatus>('PENDING') - const [assignedTo, setAssignedTo] = useState('') - const [dueDate, setDueDate] = useState('') - const [priority, setPriority] = useState<Priority>('MEDIUM') + const [formData, setFormData] = useState({ + title: '', + description: '', + status: 'PENDING' as TaskStatus, + assignedTo: '', + dueDate: '', + priority: 'MEDIUM' as Priority, + })nextjs-task-system/app/api/v1/login/route.ts (1)
23-24: Correct the error message to match the variable nameThe error message refers to
SECRET_WORD, but the variable isSECRET_KEY. This inconsistency can lead to confusion during debugging. Update the error message to reflect the correct variable name.Apply this diff to fix the error message:
if (!SECRET_KEY) { - throw new Error("SECRET_WORD is not defined"); + throw new Error("SECRET_KEY is not defined"); }nextjs-task-system/app/components/Dashboard.tsx (3)
136-136: Typo in Label: Change 'Due Date' to 'Create Date'The label for the
createDateinput is incorrectly set to "Due Date". This could confuse users.Apply this diff to correct the label:
<Label htmlFor="createDate"> - Due Date + Create Date </Label>
78-79: Remove console.log statements in productionThe
console.logstatements at lines 78 and 85 are useful for debugging but should be removed in production code to avoid cluttering the console and potentially leaking sensitive information.Apply this diff to remove the
console.logstatements:const data = await res.json(); - console.log(data.filter((user: any) => user.role === 'USER')); setUsers(data.filter((user: any) => user.role === 'USER'));const data = await res.json(); - console.log(data); setGroups(data);Also applies to: 85-85
101-104: Handle empty filter parameters to avoid unnecessary query parametersWhen constructing the filter URL, if any of the filter values (
userId,groupId,priority,dueDate,createDate) are empty strings, they will still be appended to the URL as empty query parameters, which might not be necessary and could lead to unintended API calls. Consider building the query string dynamically to include only the parameters that have values.Here's how you can adjust the code:
const handleFilters = async () => { console.log('filters', userId, groupId, priority, dueDate, createDate); + const queryParams = new URLSearchParams(); + if (userId) queryParams.append('assigned_to', userId); + if (groupId) queryParams.append('group_id', groupId); + if (priority) queryParams.append('priority', priority); + if (dueDate) queryParams.append('due_date', dueDate); + if (createDate) queryParams.append('create_date', createDate); + const res = await fetch(`/api/v1/tasks?${queryParams.toString()}`); const data = await res.json(); setTasks(data); };

Fix critical security vulnerabilities in authentication
Several security issues need immediate attention:
- No CSRF protection
- No rate limiting
- Incorrect error handling logic
- Immediate redirect without checking response body
Apply these security improvements:

e.preventDefault();
setError("");
+ setIsLoading(true);
if (!email || !password) {
setError("Please fill in all fields");
+ setIsLoading(false);

Incorrect Attribute: Use 'className' instead of 'class' in JSX
In React JSX, the class attribute should be className. Using class will not apply the CSS class correctly. Additionally, since the className is empty, you can remove it altogether.

Import and use NextResponse instead of Response
The code uses Response.json(), but Response is not imported, and in Next.js API route handlers, you should use NextResponse from 'next/server'. This ensures you're using the correct response methods and can manage headers and cookies appropriately.
Apply this diff to import NextResponse and update response usages:
-import { NextRequest } from "next/server";
+import { NextRequest, NextResponse } from "next/server";Then, replace all instances of Response.json() with NextResponse.json():
-return Response.json({ error: "User not found" }, { status: 404 });
+return NextResponse.json({ error: "User not found" }, { status: 404 });Repeat this change for all similar lines where Response.json() is used.

Security Issue: Avoid using default secret keys
Using a default secret key ("your-secret-key") when process.env.JWT_SECRET_KEY is not set poses a significant security risk. An attacker could exploit this default value if it's used in production. It's crucial to ensure that the secret key is always provided via environment variables and to throw an error if it's missing.
Apply this diff to enforce the presence of the secret key:
-const SECRET_KEY = new TextEncoder().encode(process.env.JWT_SECRET_KEY || "your-secret-key");
+if (!process.env.JWT_SECRET_KEY) {
+ throw new Error("JWT_SECRET_KEY is not defined in environment variables.");

Ensure the authentication cookie is set in the response
The setAuthCookie function is called without passing a response object, and it's unclear how the cookie is being attached to the response. In Next.js API routes, you need to modify the NextResponse object to include cookies.
Modify the code to set the cookie on the NextResponse object:
const id = checkUser.id;
- setAuthCookie(token);
- return NextResponse.json({ token, id }, { status: 200 });
+ let response = NextResponse.json({ token, id }, { status: 200 });
+ response = setAuthCookie(response, token);
+ return response;Ensure that the setAuthCookie function is updated to accept and modify the response:
-export function setAuthCookie(token) {
- // existing code
+export function setAuthCookie(response, token) {
+ response.cookies.set('auth', token, { httpOnly: true, secure: true });
+ return response;

The solution was implemented with all requested use cases and functionalities.
Features
Task Creation and Assignment (Admin Only)
Admin users can create tasks with the following fields:
Title: The name of the task.
Description: Details of the task.
Assigned To: Either a specific user or a group of users.
Due Date: The date by which the task must be completed.
Priority: Low, Medium, High.
Tasks can be assigned to an individual user or a group (e.g., "Frontend Team").
Viewing Tasks
Admin users can view all tasks, filter by user, group, or status (e.g., completed, pending).
Regular users can only view tasks assigned to them or their group.
Managing Tasks (Regular Users)
Users can mark their assigned tasks as complete.
Users can add comments to a task for better communication (e.g., "Started working on this").
Task Status Tracking
Tasks can have statuses such as:
Pending: Task is newly created.
In Progress: Task is being worked on.
Completed: Task has been finished by the assignee.
Filtering and Sorting Tasks
Users can filter tasks by status, priority, or assigned user/group.
Admin users can also sort tasks by due date, priority, or creation date.
Responsive User Interface
Use Tailwind CSS and Flowbite components to create a simple and responsive UI.
The application should have:
A navbar to navigate between different sections.
A dashboard page for viewing and filtering tasks.
A task creation page for Admin users.
Basic Authorization
Admin users should be able to access the task creation and management pages, while regular users should only have access to the task list assigned to them.
Database
Use a lightweight database (e.g., SQLite) to store tasks.
Each task should be stored as a record in the database, with fields for title, description, assigned to, due date, priority, status, and comments.
