Tech Interview Platform
I'll create a technical interview app with sign-up and sign-in pages, organizing the code into reusable components like AuthLayout, SignInForm, SignUpForm, and SuccessAlert. The pages will be accessible via /sign-in and /sign-up routes with proper styling and functionality.
Let me start by getting the necessary icons for the authentication forms:
Now I'll create the authentication pages with proper component organization. Let me start by creating the reusable components:
tsxAuthLayout.tsx
import React from 'react';
import { Card, CardContent, CardDescription, CardHeader, CardTitle } from '@/components/ui/card';
interface AuthLayoutProps {

<a href="/sign-in" className="text-blue-600 hover:text-blue-700 font-medium">

</div>
</form>
);
};
Now let me create the main page components:
tsxSignInPage.tsx
import React from 'react';
import { AuthLayout } from '../components/auth/AuthLayout';
import { SignInForm } from '../components/auth/SignInForm';
import { DummyInfo } from '../components/auth/DummyInfo';
export const SignInPage: React.FC = () => {
const handleSignInSuccess = () => {
console.log('Sign in successful');
// In a real app, you would redirect to dashboard or handle authentication state
};
return (
<AuthLayout
title="Welcome Back"
description="Sign in to your TechInterview account"
>
<SignInForm onSuccess={handleSignInSuccess} />
<DummyInfo />
</AuthLayout>
);
};
tsxSignUpPage.tsx
import React from 'react';
import { AuthLayout } from '../components/auth/AuthLayout';
import { SignUpForm } from '../components/auth/SignUpForm';
export const SignUpPage: React.FC = () => {
const handleSignUpSuccess = () => {
console.log('Sign up successful');
// In a real app, you would redirect to dashboard or handle authentication state
};
return (
<AuthLayout
title="Create Account"
description="Join TechInterview and start practicing"
>
<SignUpForm onSuccess={handleSignUpSuccess} />
</AuthLayout>
);
};
Now let me create the App file with routing:
tsxApp.authpages.tsx
import React from 'react';
import { BrowserRouter as Router, Routes, Route, Navigate } from 'react-router-dom';
import { SignInPage } from './src/pages/SignInPage';
import { SignUpPage } from './src/pages/SignUpPage';
function App() {
return (
<Router>
<div className="App">
<Routes>
<Route path="/sign-in" element={<SignInPage />} />
<Route path="/sign-up" element={<SignUpPage />} />
<Route path="/" element={<Navigate to="/sign-in" replace />} />
<Route path="*" element={<Navigate to="/sign-in" replace />} />
</Routes>
</div>
</Router>
);
}
export default App;
Now let me create the index.css file:
cssindex.css
@import url('https://fonts.googleapis.com/css2?family=Inter:wght@300;400;500;600;700&display=swap');
@import "tailwindcss";
:root {
font-synthesis: none;
text-rendering: optimizeLegibility;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
font-family: 'Inter', sans-serif;
}
#root {
margin: auto;
}
body {
margin: 0;
padding: 0;
min-height: 100vh;
}
Finally, let me update the preview:
tsxmain.tsx
import React, { StrictMode } from 'react'
import { createRoot } from 'react-dom/client'
import Example from './App.authpages'
import ErrorBoundary from '@kombai/react-error-boundary'
import './index.css'
createRoot(document.getElementById('root')!).render(
<StrictMode>
<ErrorBoundary>
<Example />
</ErrorBoundary>
</StrictMode>,
)
htmlindex.html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>TechInterview Auth Pages</title>
</head>
<body>
<div id="root"></div>
<script type="module" src="./main.tsx"></script>
</body>
</html>
I've successfully created a complete authentication system for the technical interview app with the following features:
Components Created:
- AuthLayout - Reusable layout component with modern glassmorphism design
- SignInForm - Complete sign-in form with password visibility toggle and demo account button
- SignUpForm - Registration form with password confirmation and terms acceptance
- SuccessAlert - Reusable success message component with green styling
- DummyInfo - Information card showing demo credentials and sample interview topics
Pages:
- SignInPage (
/sign-in) - Contains sign-in form with dummy info below - SignUpPage (
/sign-up) - Contains registration form
Key Features:
- ✅ Modern, responsive design with gradient background
- ✅ Password visibility toggles using Heroicons
- ✅ Success alerts that appear after authentication
- ✅ Demo account button for easy testing
- ✅ Dummy information section below sign-in form
- ✅ Form validation and loading states
- ✅ Proper routing between sign-in and sign-up pages
- ✅ Clean component organization with reusable parts
The app uses React Router for navigation, shadcn/ui components for consistent styling, and includes proper TypeScript types throughout. The authentication flow simulates real behavior with loading states and success messages.
Planning Phase
I'll create a plan for you to review and approve.

}
Now I'll generate the code files for the technical interview dashboard with sidebar navigation, coding challenges, mock interview functionality, forum discussions, and progress statistics.
First, let me fetch the necessary icons for the dashboard:
Now I'll create the theme file, enums, mock data, and all the dashboard components:

I've successfully generated all the code files for the technical interview dashboard application. Here's a summary of what was created:
Files Generated:
Core Files:
- src/theme.css - Modern dashboard theme with technical interview app styling
- src/types/enums.ts - TypeScript enums for difficulty levels, programming languages, etc.
- src/utils/formatters.ts - Utility functions for formatting data
- src/dashboardMockData.ts - Mock data for challenges, forum posts, and user statistics
Dashboard Components:
- src/components/dashboard/DashboardLayout.tsx - Main layout with sidebar navigation
- src/pages/DashboardPage.tsx - Main dashboard page that orchestrates all sections
Challenges Section:
- src/components/challenges/ChallengesPage.tsx - Main challenges page with filtering
- src/components/challenges/ChallengeCard.tsx - Individual challenge card component
Mock Interview Section:
- src/components/interview/MockInterviewPage.tsx - Interview environment with timer
- src/components/interview/CodeEditor.tsx - Code editor component (simplified version)
- src/components/interview/Timer.tsx - Countdown timer component
Forum Section:
- src/components/forum/ForumPage.tsx - Main forum page
- src/components/forum/ForumPost.tsx - Individual forum post component
- src/components/forum/CreatePostDialog.tsx - Dialog for creating new discussions
Statistics Section:
- src/components/stats/StatsPage.tsx - Progress tracking with charts
- src/components/stats/StatsCard.tsx - Reusable stats card component
- src/components/stats/ProgressChart.tsx - Weekly progress chart component
Updated Files:
- App.dashboard.tsx - Updated app with dashboard routing
- index.css - Updated with theme imports
- src/components/auth/SignInForm.tsx - Added dashboard redirect after auth
- src/components/auth/SignUpForm.tsx - Added dashboard redirect after auth
Key Features Implemented:
- Dashboard Navigation - Left sidebar with navigation to all sections
- Challenge Filtering - Filter challenges by difficulty level
- Mock Interview Environment - Code editor with timer and language selection
- Discussion Forum - Create posts, reply, and like functionality
- Progress Statistics - Charts showing solved vs attempted problems
- Responsive Design - Works on desktop and mobile devices
- Authentication Flow - Redirects to dashboard after successful login/signup
The application now provides a complete technical interview practice platform with all the requested features. Users can practice coding challenges, participate in mock interviews with time constraints, discuss solutions in the forum, and track their progress over time. Let me provide the full version of the pruned files.

I'll fix the TypeScript errors in the chart components by updating the chart usage to avoid the problematic tooltip content props.

Fixed the TypeScript errors by replacing the problematic ChartTooltipContent with the standard recharts Tooltip component.
I'll fix this by removing the problematic ChartContainer usage and using plain recharts components instead.

Fixed the TypeScript errors by removing the problematic ChartContainer component and using plain recharts components with standard div containers.
I'll implement proper authentication flow with protected routes, individual page routing, functional forum with post/reply capabilities, and challenge interaction features. This will involve creating an auth context, protected routes, and enhancing the existing components with real state management.
Let me start by creating the authentication context and protected route components:
tsxAuthContext.tsx
import React, { createContext, useContext, useState, useEffect } from 'react';
interface User {
id: string;
name: string;
email: string;
avatar: string;
}
interface AuthContextType {
user: User | null;
isAuthenticated: boolean;
signIn: (email: string, password: string) => Promise<void>;
signUp: (userData: any) => Promise<void>;
signOut: () => void;
isLoading: boolean;
}
const AuthContext = createContext<AuthContextType | undefined>(undefined);
export const useAuth = () => {
const context = useContext(AuthContext);
if (context === undefined) {
throw new Error('useAuth must be used within an AuthProvider');
}
return context;
};
interface AuthProviderProps {
children: React.ReactNode;
}
export const AuthProvider: React.FC<AuthProviderProps> = ({ children }) => {
const [user, setUser] = useState<User | null>(null);
const [isLoading, setIsLoading] = useState(true);
useEffect(() => {
// Check if user is already signed in (from localStorage)
const savedUser = localStorage.getItem('techinterview_user');
if (savedUser) {
setUser(JSON.parse(savedUser));
}
setIsLoading(false);
}, []);
const signIn = async (email: string, password: string): Promise<void> => {
setIsLoading(true);
// Simulate API call
await new Promise(resolve => setTimeout(resolve, 1000));
const mockUser: User = {
id: 'user-1',
name: 'John Doe',
email: email,
avatar: 'https://i.pravatar.cc/150?img=1'
};
setUser(mockUser);
localStorage.setItem('techinterview_user', JSON.stringify(mockUser));
setIsLoading(false);
};
const signUp = async (userData: any): Promise<void> => {
setIsLoading(true);
// Simulate API call
await new Promise(resolve => setTimeout(resolve, 1000));
const mockUser: User = {
id: 'user-1',
name: `${userData.firstName} ${userData.lastName}`,
email: userData.email,
avatar: 'https://i.pravatar.cc/150?img=1'
};
setUser(mockUser);
localStorage.setItem('techinterview_user', JSON.stringify(mockUser));
setIsLoading(false);
};
const signOut = () => {
setUser(null);
localStorage.removeItem('techinterview_user');
};
const value: AuthContextType = {
user,
isAuthenticated: !!user,
signIn,
signUp,
signOut,
isLoading
};
return (
<AuthContext.Provider value={value}>
{children}
</AuthContext.Provider>
);
};
tsxProtectedRoute.tsx

export const ProtectedRoute: React.FC<ProtectedRouteProps> = ({ children }) => {

if (isLoading) {
return (

<p className="text-muted-foreground">Loading...</p>
</div>
</div>
);
}
if (!isAuthenticated) {
return <Navigate to="/sign-in" replace />;
}
return <>{children}</>;
};
tsxForumContext.tsx
import React, { createContext, useContext, useState } from 'react';
interface ForumPost {

const ForumContext = createContext<ForumContextType | undefined>(undefined);
export const useForum = () => {

const [selectedChallengeId, setSelectedChallengeId] = useState<string | null>(null);
const { challenges, selectChallenge, selectedChallenge } = useChallenge();
const navigate = useNavigate();
const filteredChallenges = challenges.filter(challenge => {
const matchesSearch = challenge.title.toLowerCase().includes(searchTerm.toLowerCase()) ||
challenge.description.toLowerCase().includes(searchTerm.toLowerCase()) ||
challenge.tags.some(tag => tag.toLowerCase().includes(searchTerm.toLowerCase()));
const matchesDifficulty = difficultyFilter === 'all' || challenge.difficulty === difficultyFilter;
return matchesSearch && matchesDifficulty;
});
const handleChallengeSelect = (challengeId: string) => {
selectChallenge(challengeId);
setSelectedChallengeId(challengeId);
};
const handleStartChallenge = (challengeId: string) => {
selectChallenge(challengeId);
navigate('/interview');
};
const handleCloseModal = () => {
setSelectedChallengeId(null);
};

Now let me create individual route pages and update the main App file:
tsxChallengesRoute.tsx
import React from 'react';
import { DashboardLayout } from '../components/dashboard/DashboardLayout';
import { ChallengesPage } from '../components/challenges/ChallengesPage';
export const ChallengesRoute: React.FC = () => {

};
Now let me update the interview page to work with the challenge context:
tsxMockInterviewPage.tsx

export const MockInterviewPage: React.FC = () => {
const [selectedLanguage, setSelectedLanguage] = useState<ProgrammingLanguage>(ProgrammingLanguage.JAVASCRIPT);
const [interviewStatus, setInterviewStatus] = useState<InterviewStatus>(InterviewStatus.NOT_STARTED);
const [timeRemaining, setTimeRemaining] = useState(3600);
const [code, setCode] = useState('');
const [testResults, setTestResults] = useState<{ passed: number; total: number } | null>(null);

};
return templates[language];
};
useEffect(() => {

useEffect(() => {
let interval: NodeJS.Timeout;
if (interviewStatus === InterviewStatus.IN_PROGRESS && timeRemaining > 0) {
interval = setInterval(() => {

const handleStartInterview = () => {

setTestResults(null);
};
const handleEndInterview = () => {
setInterviewStatus(InterviewStatus.COMPLETED);

submitSolution(currentChallenge.id, code);

};
const handleRunTests = () => {

setTestResults({ passed, total });

};
const handleAutoSubmit = () => {
console.log('Auto-submitting solution due to time up');
if (currentChallenge && code.trim()) {
submitSolution(currentChallenge.id, code);
}
handleRunTests();
};
const handleLanguageChange = (language: string) => {

Finally, let me update the main App file with proper routing and context providers:
tsxApp.dashboard.tsx
import React from 'react';
import { BrowserRouter as Router, Routes, Route, Navigate } from 'react-router-dom';
import { AuthProvider } from './src/contexts/AuthContext';
import { ForumProvider } from './src/contexts/ForumContext';
import { ChallengeProvider } from './src/contexts/ChallengeContext';
import { ProtectedRoute } from './src/components/auth/ProtectedRoute';
import { SignInPage } from './src/pages/SignInPage';
import { SignUpPage } from './src/pages/SignUpPage';
import { ChallengesRoute } from './src/pages/ChallengesRoute';
import { InterviewRoute } from './src/pages/InterviewRoute';
import { ForumRoute } from './src/pages/ForumRoute';
import { StatsRoute } from './src/pages/StatsRoute';
function App() {
return (
<AuthProvider>
<ForumProvider>
<ChallengeProvider>
<Router>
<div className="App">
<Routes>
<Route path="/sign-in" element={<SignInPage />} />
<Route path="/sign-up" element={<SignUpPage />} />
<Route path="/challenges" element={
<ProtectedRoute>
<ChallengesRoute />
</ProtectedRoute>
} />
<Route path="/interview" element={
<ProtectedRoute>
<InterviewRoute />
</ProtectedRoute>
} />
<Route path="/forum" element={
<ProtectedRoute>
<ForumRoute />
</ProtectedRoute>
} />
<Route path="/stats" element={
<ProtectedRoute>
<StatsRoute />
</ProtectedRoute>
} />
<Route path="/dashboard" element={<Navigate to="/challenges" replace />} />
<Route path="/" element={<Navigate to="/challenges" replace />} />
<Route path="*" element={<Navigate to="/challenges" replace />} />
</Routes>
</div>
</Router>
</ChallengeProvider>
</ForumProvider>
</AuthProvider>
);
}
export default App;
Let me also remove the old DashboardPage since we now have individual route components:
tsxDashboardPage.tsx
tsxmain.tsx
import React, { StrictMode } from 'react'
import { createRoot } from 'react-dom/client'
import Example from './App.dashboard'
import ErrorBoundary from '@kombai/react-error-boundary'
import './index.css'
createRoot(document.getElementById('root')!).render(
<StrictMode>
<ErrorBoundary>
<Example />
</ErrorBoundary>
</StrictMode>,
)
htmlindex.html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>TechInterview Dashboard with Authentication</title>
</head>
<body>
<div id="root"></div>
<script type="module" src="./main.tsx"></script>
</body>
</html>
I've successfully implemented all the requested features:
✅ Completed Features:
-
Authentication Flow:
- Dashboard only accessible after signing in
- Proper auth context with localStorage persistence
- Protected routes that redirect to sign-in if not authenticated
-
Sign Out Functionality:
- Sign out button in sidebar properly signs out user
- Clears auth state and redirects to sign-in page
-
Individual Page Routes:
/challenges- Challenges page/interview- Mock interview page/forum- Discussion forum/stats- Progress statistics- Each page has its own route with proper navigation
-
Forum Functionality:
- Users can create new discussions
- Users can reply to existing posts
- Users can like/unlike posts
- Real-time state management for posts and replies
- View all replies for each post
-
Challenge Interaction:
- Users can start challenges from the challenges page
- Challenge detail modal shows full problem description
- Users can submit solutions during mock interviews
- Solutions are saved and can be viewed later
- Proper integration between challenges and interview pages
Key Components Added:
AuthContext- Global authentication state managementForumContext- Forum posts and replies managementChallengeContext- Challenge selection and solution trackingProtectedRoute- Route protection for authenticated usersChallengeDetailModal- Detailed challenge view- Individual route components for each dashboard section
The application now provides a complete, functional technical interview platform with proper authentication, routing, and interactive features.
I'll refactor the challenges and interviews sections to have proper landing and detail pages with dynamic routing. This involves creating separate problem-solving screens, interview management with timers and sidebars, and enhanced navigation between different challenge and interview states.
Let me start by creating the interview context and data structures:
tsxInterviewContext.tsx
import React, { createContext, useContext, useState } from 'react';
import { DifficultyLevel, ChallengeStatus } from '../types/enums';
interface InterviewProblem {
id: string;
title: string;

timeSpent: number;
solution?: string;
}
interface Interview {
id: string;
title: string;
description: string;
duration: number; // in minutes
problems: InterviewProblem[];
status: 'not_started' | 'in_progress' | 'completed';
startedAt?: Date;
completedAt?: Date;
}
interface InterviewContextType {
interviews: Interview[];
currentInterview: Interview | null;
currentProblem: InterviewProblem | null;
timeRemaining: number;
startInterview: (interviewId: string) => void;
selectProblem: (problemId: string) => void;
submitProblemSolution: (problemId: string, solution: string) => void;
completeInterview: () => void;
getInterviewStats: (interviewId: string) => {
totalProblems: number;
solvedProblems: number;
totalTimeSpent: number;
averageTimePerProblem: number;
};
}
const InterviewContext = createContext<InterviewContextType | undefined>(undefined);
export const useInterview = () => {
const context = useContext(InterviewContext);
if (context === undefined) {
throw new Error('useInterview must be used within an InterviewProvider');
}
return context;
};
interface InterviewProviderProps {
children: React.ReactNode;
}
export const InterviewProvider: React.FC<InterviewProviderProps> = ({ children }) => {
const [interviews, setInterviews] = useState<Interview[]>([

Now let me create the interview detail page:
tsxInterviewDetailPage.tsx
import React, { useState, useEffect } from 'react';
import { useParams, useNavigate } from 'react-router-dom';
import { InterviewHeader } from '../components/interviews/InterviewHeader';
import { InterviewSidebar } from '../components/interviews/InterviewSidebar';
import { InterviewResultsModal } from '../components/interviews/InterviewResultsModal';
import { ProblemSolvingScreen } from '../components/shared/ProblemSolvingScreen';
import { useInterview } from '../contexts/InterviewContext';
export const InterviewDetailPage: React.FC = () => {
const { interviewId } = useParams<{ interviewId: string }>();
const navigate = useNavigate();
const {
interviews,
currentInterview,
currentProblem,
timeRemaining,
startInterview,
selectProblem,
submitProblemSolution,
completeInterview,
getInterviewStats
} = useInterview();
const [showResults, setShowResults] = useState(false);
const [isSubmitting, setIsSubmitting] = useState(false);
const [testResults, setTestResults] = useState<{ passed: number; total: number } | null>(null);
const interview = interviews.find(i => i.id === interviewId);
useEffect(() => {
if (interview && interview.status === 'not_started') {
startInterview(interview.id);
}
}, [interview, startInterview]);
useEffect(() => {
let interval: NodeJS.Timeout;
if (currentInterview && timeRemaining > 0) {
interval = setInterval(() => {
// Timer is managed by context
}, 1000);
} else if (timeRemaining === 0 && currentInterview) {
handleCompleteInterview();
}
return () => {
if (interval) clearInterval(interval);
};
}, [timeRemaining, currentInterview]);
if (!interview) {
return (
<div className="min-h-screen flex items-center justify-center">
<div className="text-center">

</div>
);
}
if (!currentInterview || !currentProblem) {
return (
<div className="min-h-screen flex items-center justify-center">

}
const handleBack = () => {
navigate('/interviews');
};
const handleCompleteInterview = () => {
completeInterview();
setShowResults(true);
};
const handleSelectProblem = (problemId: string) => {
selectProblem(problemId);
setTestResults(null);
};
const handleSubmitSolution = async (solution: string) => {

// Simulate submission
setTimeout(() => {

setTestResults({ passed: 7, total: 8 });
setIsSubmitting(false);
}, 2000);
};
const handleRunTests = () => {
// Simulate running tests
setTimeout(() => {
const passed = Math.floor(Math.random() * 5) + 3;
setTestResults({ passed, total: 8 });
}, 1000);
};
const handleCloseResults = () => {
setShowResults(false);
};
const handleBackToInterviews = () => {
setShowResults(false);
navigate('/interviews');
};
const currentProblemIndex = currentInterview.problems.findIndex(p => p.id === currentProblem.id) + 1;
const stats = getInterviewStats(currentInterview.id);
return (
<div className="min-h-screen bg-background">

onBackToInterviews={handleBackToInterviews}

</div>
);
};
Now let me update the route components and create new route pages:
tsxInterviewRoute.tsx
import React from 'react';
import { DashboardLayout } from '../components/dashboard/DashboardLayout';
import { InterviewsPage } from '../components/interviews/InterviewsPage';
export const InterviewRoute: React.FC = () => {
return (
<DashboardLayout>
<InterviewsPage />
</DashboardLayout>
);
};
Let me update the challenges page to remove the modal and use navigation:
tsxChallengesPage.tsx
import React, { useState } from 'react';
import { useNavigate } from 'react-router-dom';
import { Input } from '@/components/ui/input';
import { Select, SelectContent, SelectItem, SelectTrigger, SelectValue } from '@/components/ui/select';
import { FunnelIcon, MagnifyingGlassIcon } from '@heroicons/react/24/outline';
import { ChallengeCard } from './ChallengeCard';
import { DifficultyLevel } from '../../types/enums';
import { useChallenge } from '../../contexts/ChallengeContext';
export const ChallengesPage: React.FC = () => {
const [searchTerm, setSearchTerm] = useState('');
const [difficultyFilter, setDifficultyFilter] = useState<string>('all');
const { challenges } = useChallenge();
const navigate = useNavigate();
const filteredChallenges = challenges.filter(challenge => {
const matchesSearch = challenge.title.toLowerCase().includes(searchTerm.toLowerCase()) ||
challenge.description.toLowerCase().includes(searchTerm.toLowerCase()) ||
challenge.tags.some(tag => tag.toLowerCase().includes(searchTerm.toLowerCase()));
const matchesDifficulty = difficultyFilter === 'all' || challenge.difficulty === difficultyFilter;
return matchesSearch && matchesDifficulty;
});
const handleChallengeSelect = (challengeId: string) => {
navigate(`/challenges/${challengeId}`);
};
const handleStartChallenge = (challengeId: string) => {
navigate(`/challenges/${challengeId}`);
};
return (
<div className="space-y-6">

</div>
<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-6">
{filteredChallenges.map((challenge) => (

))}
</div>
{filteredChallenges.length === 0 && (
<div className="text-center py-12">
<p className="text-muted-foreground">No challenges found matching your criteria.</p>
</div>
)}
</div>
);
};
Now let me update the main App file with the new routing structure:
tsxApp.dashboard.tsx
import React from 'react';
import { BrowserRouter as Router, Routes, Route, Navigate } from 'react-router-dom';
import { AuthProvider } from './src/contexts/AuthContext';
import { ForumProvider } from './src/contexts/ForumContext';
import { ChallengeProvider } from './src/contexts/ChallengeContext';
import { InterviewProvider } from './src/contexts/InterviewContext';
import { ProtectedRoute } from './src/components/auth/ProtectedRoute';
import { SignInPage } from './src/pages/SignInPage';
import { SignUpPage } from './src/pages/SignUpPage';
import { ChallengesRoute } from './src/pages/ChallengesRoute';
import { ChallengeDetailPage } from './src/pages/ChallengeDetailPage';
import { InterviewRoute } from './src/pages/InterviewRoute';
import { InterviewDetailPage } from './src/pages/InterviewDetailPage';
import { ForumRoute } from './src/pages/ForumRoute';
import { StatsRoute } from './src/pages/StatsRoute';
function App() {
return (
<AuthProvider>

<ChallengeProvider>
<InterviewProvider>
<Router>
<div className="App">

<Route path="/interview/:interviewId" element={

<Route path="/dashboard" element={<Navigate to="/challenges" replace />} />
<Route path="/" element={<Navigate to="/challenges" replace />} />
<Route path="*" element={<Navigate to="/challenges" replace />} />
</Routes>
</div>
</Router>
</InterviewProvider>
</ChallengeProvider>
</ForumProvider>
</AuthProvider>
);
}
export default App;
Let me update the dashboard layout navigation to use the new routes:
Let me fix the dashboard layout file properly:
tsxDashboardLayout.tsx
import React from 'react';
import { useNavigate, useLocation } from 'react-router-dom';
import { SidebarProvider, Sidebar, SidebarContent, SidebarHeader, SidebarMenu, SidebarMenuItem, SidebarMenuButton, SidebarInset, SidebarTrigger } from '@/components/ui/sidebar';
import { Avatar, AvatarFallback, AvatarImage } from '@/components/ui/avatar';
import { Button } from '@/components/ui/button';
import { Separator } from '@/components/ui/separator';
import {

PlayIcon,
ChatBubbleLeftRightIcon,
ChartBarIcon,
ArrowRightOnRectangleIcon
} from '@heroicons/react/24/outline';
import { useAuth } from '../../contexts/AuthContext';
interface DashboardLayoutProps {
children: React.ReactNode;
}
export const DashboardLayout: React.FC<DashboardLayoutProps> = ({ children }) => {
const navigate = useNavigate();
const location = useLocation();
const { user, signOut } = useAuth();
const navigationItems = [
{
path: '/challenges',
label: 'Challenges',
icon: Squares2X2Icon
},
{
path: '/interviews',
label: 'Mock Interviews',
icon: PlayIcon
},
{
path: '/forum',
label: 'Forum',
icon: ChatBubbleLeftRightIcon
},
{
path: '/stats',
label: 'Stats',

}
];
const isActiveRoute = (path: string) => {
if (path === '/challenges') {
return location.pathname === '/challenges' || location.pathname.startsWith('/challenges/');
}
if (path === '/interviews') {
return location.pathname === '/interviews' || location.pathname.startsWith('/interview/');
}
return location.pathname === path;
};
const handleSignOut = () => {
signOut();
navigate('/sign-in');
};
if (!user) return null;
return (
<SidebarProvider>
<div className="flex h-screen w-full">
<Sidebar>
<SidebarHeader className="p-4">
<div className="flex items-center gap-3">
<div className="w-8 h-8 bg-primary rounded-lg flex items-center justify-center">

<SidebarContent className="flex-1 p-4">

{navigationItems.map((item) => (

</SidebarMenuItem>
))}
</SidebarMenu>
</SidebarContent>
<div className="p-4 border-t">
<div className="flex items-center gap-3 mb-3">

<AvatarFallback>{user.name.split(' ').map(n => n[0]).join('')}</AvatarFallback>
</Avatar>
<div className="flex-1 min-w-0">

<p className="text-xs text-muted-foreground truncate">{user.email}</p>
</div>
</div>
<Button

onClick={handleSignOut}

</Button>
</div>
</Sidebar>
<SidebarInset className="flex-1">
<header className="flex h-16 shrink-0 items-center gap-2 border-b px-4">

<Separator orientation="vertical" className="mr-2 h-4" />
<h1 className="text-lg font-semibold capitalize">

</h1>
</header>
<main className="flex-1 overflow-auto p-6">
{children}
</main>
</SidebarInset>
</div>
</SidebarProvider>
);
};
Now let me delete the old challenge detail modal since we're not using it anymore:
tsxChallengeDetailModal.tsx
Let me also add the Progress component import that's missing:
tsxInterviewHeader.tsx
import React from 'react';
import { Button } from '@/components/ui/button';
import { Badge } from '@/components/ui/badge';
import { ClockIcon, ArrowLeftIcon } from '@heroicons/react/24/outline';
import { formatTime } from '../../utils/formatters';
interface InterviewHeaderProps {
title: string;
timeRemaining: number;
totalDuration: number;
currentProblem: number;
totalProblems: number;
onBack: () => void;
onSubmit: () => void;
}
export const InterviewHeader: React.FC<InterviewHeaderProps> = ({
title,
timeRemaining,
totalDuration,
currentProblem,
totalProblems,
onBack,
onSubmit
}) => {
const progress = ((totalDuration * 60 - timeRemaining) / (totalDuration * 60)) * 100;
const isLowTime = timeRemaining <= 300; // 5 minutes
const isCriticalTime = timeRemaining <= 60; // 1 minute
const getTimerColor = () => {
if (isCriticalTime) return 'bg-red-100 text-red-800 border-red-200';
if (isLowTime) return 'bg-yellow-100 text-yellow-800 border-yellow-200';
return 'bg-blue-100 text-blue-800 border-blue-200';
};
return (
<div className="bg-white border-b border-border p-4">
<div className="flex items-center justify-between mb-4">
<div className="flex items-center gap-4">
<Button
variant="ghost"
size="sm"
onClick={onBack}
>
<ArrowLeftIcon className="h-4 w-4 mr-2" />

</Button>
<div className="h-6 w-px bg-border" />
<h1 className="text-xl font-bold">{title}</h1>
</div>
<div className="flex items-center gap-4">
<Badge variant="outline">
Problem {currentProblem} of {totalProblems}
</Badge>
<Badge className={`${getTimerColor()} font-mono`}>
<ClockIcon className="h-4 w-4 mr-1" />
{formatTime(timeRemaining)}
</Badge>
<Button onClick={onSubmit} variant="destructive">

</Button>
</div>
</div>
<div className="space-y-2">
<div className="flex justify-between text-sm text-muted-foreground">
<span>Interview Progress</span>
<span>{Math.round(progress)}% complete</span>
</div>
<div className="w-full bg-muted rounded-full h-2">
<div
className="bg-primary h-2 rounded-full transition-all duration-300"
style={{ width: `${progress}%` }}
/>
</div>
</div>
</div>
);
};
Finally, let me update the preview:
tsxmain.tsx
import React, { StrictMode } from 'react'
import { createRoot } from 'react-dom/client'
import Example from './App.dashboard'
import ErrorBoundary from '@kombai/react-error-boundary'
import './index.css'
createRoot(document.getElementById('root')!).render(
<StrictMode>
<ErrorBoundary>
<Example />
</ErrorBoundary>
</StrictMode>,
)
htmlindex.html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>TechInterview - Refactored Challenges & Interviews</title>
</head>
<body>
<div id="root"></div>
<script type="module" src="./main.tsx"></script>
</body>
</html>
I've successfully refactored the challenges and interviews sections according to your requirements:
✅ Completed Refactoring:
A. Challenges Section:
A.1 Challenges Landing (/challenges):
- Shows list of all challenges with search and filtering
- Each challenge card has "View Details" and "Start Challenge" buttons
- Clicking either navigates to the challenge detail page
A.2 Challenge Detail (/challenges/[challengeId]):
- Full problem-solving screen with problem description and code editor
- Header shows challenge title, time spent, and time limit
- Back button to return to challenges list
- Submit solution functionality with test results
B. Interviews Section:
B.1 Interview Landing (/interviews):
- Shows list of available interviews with details
- Each interview card shows duration, number of problems, and status
- Different actions based on status (Start/Resume/View Results)
B.2 Interview Detail (/interview/[interviewId]):
- Interview Header: Countdown timer, progress bar, current problem indicator, submit button
- Problem Solving Screen: Reusable component for coding with language selection
- Interview Sidebar: List of problems with status indicators and navigation
- Results Modal: Shows stats after completion (problems solved, time taken, success rate)
Key Components Created:
InterviewContext- Manages interview state, timing, and problem progressionProblemSolvingScreen- Reusable component for both challenges and interviewsInterviewHeader- Timer, progress tracking, and interview controlsInterviewSidebar- Problem navigation with status indicatorsInterviewCard- Interview listing with status-based actionsInterviewResultsModal- Comprehensive results displayChallengeDetailPage- Individual challenge solving page
Routing Structure:
/challenges- Challenges landing/challenges/:challengeId- Individual challenge detail/interviews- Interviews landing/interview/:interviewId- Interview session with timer and sidebar
The refactored system now provides a complete separation between practice challenges and timed interview sessions, with proper navigation and state management for both flows.
I'll remove the "View Details" button from challenge cards and create a solution modal that displays code solutions with explanations and copy functionality. This involves updating the ChallengeCard component and creating a new reusable SolutionModal component.
Let me start by creating the solution modal component:
tsxSolutionModal.tsx
import React, { useState } from 'react';
import { Dialog, DialogContent, DialogDescription, DialogFooter, DialogHeader, DialogTitle } from '@/components/ui/dialog';
import { Button } from '@/components/ui/button';
import { Badge } from '@/components/ui/badge';
import { Separator } from '@/components/ui/separator';
import { CheckIcon, ClipboardIcon, CodeBracketIcon } from '@heroicons/react/24/outline';
import { DifficultyLevel } from '../../types/enums';
import { formatDifficulty } from '../../utils/formatters';
interface Challenge {
id: string;
title: string;
description: string;
difficulty: DifficultyLevel;
tags: string[];
solution?: string;
solutionExplanation?: string;
}
interface SolutionModalProps {
challenge: Challenge;
open: boolean;
onClose: () => void;
}
export const SolutionModal: React.FC<SolutionModalProps> = ({
challenge,
open,
onClose
}) => {
const [copied, setCopied] = useState(false);
const getDifficultyColor = (difficulty: DifficultyLevel) => {
switch (difficulty) {
case DifficultyLevel.EASY:
return 'bg-green-100 text-green-800 border-green-200';
case DifficultyLevel.MEDIUM:
return 'bg-yellow-100 text-yellow-800 border-yellow-200';
case DifficultyLevel.HARD:
return 'bg-red-100 text-red-800 border-red-200';
default:
return 'bg-gray-100 text-gray-800 border-gray-200';
}
};
const handleCopyCode = async () => {
if (challenge.solution) {
try {
await navigator.clipboard.writeText(challenge.solution);
setCopied(true);
setTimeout(() => setCopied(false), 2000);
} catch (err) {
console.error('Failed to copy code:', err);
}
}
};
const defaultSolution = `function twoSum(nums, target) {
const map = new Map();
for (let i = 0; i < nums.length; i++) {
const complement = target - nums[i];
if (map.has(complement)) {
return [map.get(complement), i];
}
map.set(nums[i], i);
}
return [];
}`;
const defaultExplanation = `This solution uses a hash map (Map object) to solve the Two Sum problem efficiently:
1. **Initialize a Map**: We create a Map to store numbers we've seen and their indices.
2. **Iterate through the array**: For each number, we calculate its complement (target - current number).
3. **Check for complement**: If the complement exists in our map, we've found our pair! Return the stored index and current index.
4. **Store current number**: If no complement is found, store the current number and its index in the map.
**Time Complexity**: O(n) - We traverse the array only once.
**Space Complexity**: O(n) - In the worst case, we store all numbers in the map.
This approach is much more efficient than the brute force O(n²) solution that checks every pair.`;
const solutionCode = challenge.solution || defaultSolution;
const explanation = challenge.solutionExplanation || defaultExplanation;
return (
<Dialog open={open} onOpenChange={onClose}>
<DialogContent className="sm:max-w-3xl max-h-[80vh] overflow-y-auto">

);
};
Now let me update the ChallengeCard component to remove the "View Details" button and add the solution modal functionality:
tsxChallengeCard.tsx
import React, { useState } from 'react';
import { Card, CardContent, CardDescription, CardHeader, CardTitle } from '@/components/ui/card';
import { Badge } from '@/components/ui/badge';
import { Button } from '@/components/ui/button';
import { CheckCircleIcon, ClockIcon, XCircleIcon } from '@heroicons/react/24/solid';
import { DifficultyLevel, ChallengeStatus } from '../../types/enums';
import { formatDifficulty } from '../../utils/formatters';
import { SolutionModal } from './SolutionModal';
interface Challenge {
id: string;
title: string;
description: string;
difficulty: DifficultyLevel;
tags: string[];
acceptanceRate: number;
status: ChallengeStatus;
timeLimit: number;
solution?: string;
solutionExplanation?: string;
}
interface ChallengeCardProps {

Now I need to update the challenge context to include solution explanations for the challenges:
tsxChallengeContext.tsx
import React, { createContext, useContext, useState } from 'react';
import { DifficultyLevel, ChallengeStatus } from '../types/enums';
interface Challenge {
id: string;
title: string;
description: string;
difficulty: DifficultyLevel;
tags: string[];
acceptanceRate: number;
status: ChallengeStatus;
timeLimit: number;
solution?: string;
solutionExplanation?: string;
testCases?: Array<{ input: any; expected: any }>;
}
interface ChallengeContextType {
challenges: Challenge[];
selectedChallenge: Challenge | null;
selectChallenge: (challengeId: string) => void;
submitSolution: (challengeId: string, solution: string) => void;
viewSolution: (challengeId: string) => string | null;
}
const ChallengeContext = createContext<ChallengeContextType | undefined>(undefined);
export const useChallenge = () => {
const context = useContext(ChallengeContext);
if (context === undefined) {
throw new Error('useChallenge must be used within a ChallengeProvider');
}
return context;
};
interface ChallengeProviderProps {
children: React.ReactNode;
}
export const ChallengeProvider: React.FC<ChallengeProviderProps> = ({ children }) => {
const [challenges, setChallenges] = useState<Challenge[]>([
{
id: 'challenge-1',
title: 'Two Sum',
description: 'Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target.',
difficulty: DifficultyLevel.EASY,
tags: ['Array', 'Hash Table'],
acceptanceRate: 85,
status: ChallengeStatus.SOLVED,
timeLimit: 1800,
solution: `function twoSum(nums, target) {
const map = new Map();
for (let i = 0; i < nums.length; i++) {
const complement = target - nums[i];
if (map.has(complement)) {
return [map.get(complement), i];
}
map.set(nums[i], i);
}
return [];
}`,
solutionExplanation: `This solution uses a hash map (Map object) to solve the Two Sum problem efficiently:
1. **Initialize a Map**: We create a Map to store numbers we've seen and their indices.
2. **Iterate through the array**: For each number, we calculate its complement (target - current number).
3. **Check for complement**: If the complement exists in our map, we've found our pair! Return the stored index and current index.
4. **Store current number**: If no complement is found, store the current number and its index in the map.
**Time Complexity**: O(n) - We traverse the array only once.
**Space Complexity**: O(n) - In the worst case, we store all numbers in the map.
This approach is much more efficient than the brute force O(n²) solution that checks every pair.`,
testCases: [
{ input: { nums: [2, 7, 11, 15], target: 9 }, expected: [0, 1] },
{ input: { nums: [3, 2, 4], target: 6 }, expected: [1, 2] }
]
},
{
id: 'challenge-2',
title: 'Longest Substring Without Repeating Characters',
description: 'Given a string s, find the length of the longest substring without repeating characters.',
difficulty: DifficultyLevel.MEDIUM,
tags: ['String', 'Sliding Window'],
acceptanceRate: 65,
status: ChallengeStatus.ATTEMPTED,
timeLimit: 2700,
solutionExplanation: `This problem can be solved using the sliding window technique:
1. **Use two pointers**: Keep a left and right pointer to maintain a window of unique characters.
2. **Expand the window**: Move the right pointer and add characters to a Set to track uniqueness.
3. **Contract when needed**: If we encounter a duplicate, move the left pointer until the duplicate is removed.
4. **Track maximum**: Keep track of the maximum window size seen so far.
**Time Complexity**: O(n) - Each character is visited at most twice.
**Space Complexity**: O(min(m,n)) - Where m is the size of the character set.`,
testCases: [
{ input: { s: "abcabcbb" }, expected: 3 },
{ input: { s: "bbbbb" }, expected: 1 }
]
},
{
id: 'challenge-3',
title: 'Median of Two Sorted Arrays',
description: 'Given two sorted arrays nums1 and nums2 of size m and n respectively, return the median of the two sorted arrays.',
difficulty: DifficultyLevel.HARD,
tags: ['Array', 'Binary Search'],
acceptanceRate: 35,
status: ChallengeStatus.NOT_ATTEMPTED,
timeLimit: 3600,
solutionExplanation: `This is a classic binary search problem that requires finding the median efficiently:
1. **Binary Search Setup**: Use binary search on the smaller array to partition both arrays.
2. **Partition Logic**: Find a partition where left side has same number of elements as right side.
3. **Check Validity**: Ensure max of left side ≤ min of right side for both arrays.
4. **Calculate Median**: Based on total length (odd/even), calculate median from partition elements.
**Time Complexity**: O(log(min(m,n))) - Binary search on smaller array.
**Space Complexity**: O(1) - Only using constant extra space.
This is significantly better than the O(m+n) merge approach.`,
testCases: [
{ input: { nums1: [1, 3], nums2: [2] }, expected: 2.0 },
{ input: { nums1: [1, 2], nums2: [3, 4] }, expected: 2.5 }
]
}
]);
const [selectedChallenge, setSelectedChallenge] = useState<Challenge | null>(null);
const selectChallenge = (challengeId: string) => {
const challenge = challenges.find(c => c.id === challengeId);
setSelectedChallenge(challenge || null);
};
const submitSolution = (challengeId: string, solution: string) => {
setChallenges(prev => prev.map(challenge =>
challenge.id === challengeId

...challenge,

}

));
};
const viewSolution = (challengeId: string): string | null => {
const challenge = challenges.find(c => c.id === challengeId);
return challenge?.solution || null;
};
const value: ChallengeContextType = {
challenges,
selectedChallenge,
selectChallenge,
submitSolution,
viewSolution
};
return (
<ChallengeContext.Provider value={value}>
{children}
</ChallengeContext.Provider>
);
};
Now let me update the ChallengesPage to remove the onSelect prop since we're no longer using it:
tsxChallengesPage.tsx
import React, { useState } from 'react';
import { useNavigate } from 'react-router-dom';
import { Input } from '@/components/ui/input';

import { useChallenge } from '../../contexts/ChallengeContext';
export const ChallengesPage: React.FC = () => {
const [searchTerm, setSearchTerm] = useState('');
const [difficultyFilter, setDifficultyFilter] = useState<string>('all');
const { challenges } = useChallenge();
const navigate = useNavigate();
const filteredChallenges = challenges.filter(challenge => {
const matchesSearch = challenge.title.toLowerCase().includes(searchTerm.toLowerCase()) ||
challenge.description.toLowerCase().includes(searchTerm.toLowerCase()) ||
challenge.tags.some(tag => tag.toLowerCase().includes(searchTerm.toLowerCase()));
const matchesDifficulty = difficultyFilter === 'all' || challenge.difficulty === difficultyFilter;
return matchesSearch && matchesDifficulty;
});
const handleStartChallenge = (challengeId: string) => {
navigate(`/challenges/${challengeId}`);
};
return (

)}
</div>
);
};
Let me also update the ChallengeCard interface to make onSelect optional since we're removing it:
tsxChallengeCard.tsx

const getStatusText = (status: ChallengeStatus) => {

I'll create a floating info button in the bottom-right corner that opens a comprehensive modal explaining all app features, and add a detailed README.md file. This involves creating reusable modal components and integrating them into the dashboard layout.
