Architectural Principles

1. Component-Driven: Modular, reusable components
2. Separation of Concerns: Pages, components, hooks, utilities
3. Type Safety: Full TypeScript coverage
4. DRY (Don't Repeat Yourself): Utilities & hooks for shared logic
5. Responsive First: Mobile-first design approach
6. Performance: Code splitting, lazy loading ready

• Bun 1.x (recommended) OR npm 9.x+
• Git

Step 1: Clone the Repository

git clone https://github.com/Aditya24Kashyap/WatchAlong.git
cd WatchAlong

Step 2: Install Dependencies

Using Bun (Recommended - Faster)

bun install

Using npm (Alternative)

npm install

Step 3: Verify Installation

npm run lint

💻 Development

Start Development Server

npm run dev

The application will be available at http://localhost:5173

Features

• 🔥 Hot Module Replacement (HMR): Changes reflect instantly
• 📊 Fast Refresh: Preserves component state
• 🐛 Source Maps: Easy debugging

Code Quality

Run ESLint

npm run lint

Fix Linting Issues

npm run lint:fix

Type Check

npx tsc --noEmit

Adding New Components

1. Create Component File

# Create a new component in src/components/
touch src/components/MyComponent.tsx

2. Component Template

import { FC } from 'react';

interface MyComponentProps {
  title: string;
  onClick?: () => void;
}

const MyComponent: FC<MyComponentProps> = ({ title, onClick }) => {
  return (
    <div className="p-4 bg-white rounded-lg shadow">
      <h2 className="text-xl font-bold">{title}</h2>
      <button onClick={onClick} className="mt-4 px-4 py-2 bg-blue-500 text-white rounded">
        Click me
      </button>
    </div>
  );
};

export default MyComponent;

3. Import & Use

import MyComponent from '@/components/MyComponent';

export default function App() {
  return <MyComponent title="Hello World" />;
}

Adding Custom Hooks

touch src/hooks/useMyHook.ts

import { useState, useCallback } from 'react';

export const useMyHook = (initialValue: string) => {
  const [value, setValue] = useState(initialValue);

  const reset = useCallback(() => {
    setValue(initialValue);
  }, [initialValue]);

  return { value, setValue, reset };
};

2. Vite builds optimized bundles
3. CSS is minified & tree-shaken
4. JavaScript is minified & code-split

Preview Production Build

npm run preview

Deployment Options

Vercel (Recommended)

# Install Vercel CLI
npm i -g vercel

# Deploy
vercel

Netlify

1. Connect your GitHub repository
2. Set build command: npm run build
3. Set publish directory: dist

Docker

FROM node:18-alpine
WORKDIR /app
COPY package.json bun.lockb ./
RUN npm install
COPY . .
RUN npm run build
EXPOSE 5173
CMD ["npm", "run", "preview"]

Traditional Hosting

npm run build
# Upload dist/ folder to your hosting provider
