This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

• @vitejs/plugin-react uses Babel (or oxc when used in rolldown-vite) for Fast Refresh
• @vitejs/plugin-react-swc uses SWC for Fast Refresh

The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.

If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:

export default defineConfig([
  globalIgnores(['dist']),
  {
    files: ['**/*.{ts,tsx}'],
    extends: [
      // Other configs...

      // Remove tseslint.configs.recommended and replace with this
      tseslint.configs.recommendedTypeChecked,
      // Alternatively, use this for stricter rules
      tseslint.configs.strictTypeChecked,
      // Optionally, add this for stylistic rules
      tseslint.configs.stylisticTypeChecked,

      // Other configs...
    ],
    languageOptions: {
      parserOptions: {
        project: ['./tsconfig.node.json', './tsconfig.app.json'],
        tsconfigRootDir: import.meta.dirname,
      },
      // other options...
    },
  },
])

You can also install eslint-plugin-react-x and eslint-plugin-react-dom for React-specific lint rules:

// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'

export default defineConfig([
  globalIgnores(['dist']),
  {
    files: ['**/*.{ts,tsx}'],
    extends: [
      // Other configs...
      // Enable lint rules for React
      reactX.configs['recommended-typescript'],
      // Enable lint rules for React DOM
      reactDom.configs.recommended,
    ],
    languageOptions: {
      parserOptions: {
        project: ['./tsconfig.node.json', './tsconfig.app.json'],
        tsconfigRootDir: import.meta.dirname,
      },
      // other options...
    },
  },
])

A collection of React + TypeScript machine coding interview questions and solutions. This repo contains various UI components commonly asked in frontend interview rounds.

• Pagination - Implement paginated product listing with page size selector
• Autocomplete - Search with caching and debouncing
• Tab Form - Multi-step form with validation across tabs
• Profile - Form component with dynamic field handling
• Interest Selection - Multi-select component
• Settings - Configuration panel

• React 18 - UI library
• TypeScript - Type safety
• Vite - Build tool with HMR
• CSS - Styling

• Node.js (v16+)
• npm or yarn

npm install
npm run dev

npm run build

npm run preview

• State Management - useState, useEffect, useCallback
• Performance - useMemo, useCallback, debouncing, caching
• Type Safety - TypeScript interfaces and generics
• Form Handling - Controlled components, validation
• UI Patterns - Pagination, search, multi-step forms, tabs

For stricter type checking in production, update your ESLint config to enable type-aware rules:

tseslint.configs.strictTypeChecked

Optional: Add React-specific lint rules:

import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'

• Focus on component reusability
• Handle edge cases (empty states, loading, errors)
• Optimize performance (memoization, caching)
• Write clean, readable code
• Add proper TypeScript types
• Consider accessibility (aria labels, semantic HTML)

• React Documentation
• TypeScript Handbook
• Vite Guide

Practice hard, code clean! 🚀
