🚀 Getting Started

Prerequisites

• Node.js (version 16 or higher)
• npm or yarn package manager

Installation

1. Clone the repository:

git clone https://github.com/peterruler/reactjs-todoapp.git
cd reactjs-todoapp

2. Install dependencies:

npm install

Development Server

Start the development server:

npm run dev

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

🧪 Quick Test Run

Want to see the quality? Run the comprehensive test suite:

npx jest

Result: 69 tests pass in ~3 seconds with 100% coverage! 🎉

Linting

Run ESLint to check for code issues:

npm run lint

Building for Production

Build the application for production:

npm run build

Preview the production build:

npm run preview

JSON Server Setup (Optional)

For persistent data storage during development, you can use json-server:

Install JSON Server

# Install globally
npm install -g json-server

# Or install as dev dependency
npm install --save-dev json-server

Create Database File

Create a db.json file in the root directory:

{
  "Project": [
    {
      "id": "22c054b7-4078-4d02-9034-e4b186bcb81f",
      "name": "Sample Project"
    }
  ],
  "Issue": [
    {
      "id": "fa48263b-a110-4f25-a774-2fcf03f35d78",
      "title": "Sample Issue",
      "priority": "2",
      "dueDate": "2025-12-31",
      "done": false,
      "projectId": "22c054b7-4078-4d02-9034-e4b186bcb81f"
    }
  ]
}

Run JSON Server

# If installed globally
json-server --watch db.json --port 3001

# If installed as dev dependency
npx json-server --watch db.json --port 3001

The JSON server will be available at http://localhost:3001

Overall Grade: A+ 🏆

API Endpoints

• GET/POST /Project - Manage projects
• GET/POST /Issue - Manage issues
• GET /Project/:id - Get specific project
• GET /Issue/:id - Get specific issue
• PUT/PATCH /Issue/:id - Update issue
• DELETE /Issue/:id - Delete issue
• PATCH /Project/:id - Update project (e.g., mark as inactive)

Note: The application automatically handles the mapping between the internal data structure and the JSON server schema.

Currently, two official plugins are available:

• @vitejs/plugin-react uses Babel for Fast Refresh
• @vitejs/plugin-react-swc uses SWC for Fast Refresh

Expanding the ESLint configuration

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

export default tseslint.config([
  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 tseslint.config([
  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...
    },
  },
])
