8. Contribution Guidelines

8.1. Code Style & Best Practices

Coding Standards

1. TypeScript Guidelines

   // Use explicit types
   interface User {
     id: string;
     email: string;
     role: UserRole;
     metadata?: Record<string, unknown>;
   }
   
   // Use enums for fixed values
   enum UserRole {
     ADMIN = 'admin',
     USER = 'user',
     GUEST = 'guest',
   }
   
   // Use meaningful variable names
   const userSubscription: Subscription;  // ✅
   const sub: Subscription;               // ❌
   

2. React Components

   // Use functional components
   const UserProfile: React.FC<UserProfileProps> = ({ user, onUpdate }) => {
     // Use hooks at the top level
     const [isEditing, setIsEditing] = useState(false);
     const { data, loading } = useQuery(USER_QUERY);
   
     // Group related state
     const { name, email } = user;
   
     return (
       <div className="user-profile">
         {/* JSX */}
       </div>
     );
   };
   

3. File Organization

   ├── components/
   │   ├── common/           # Shared components
   │   ├── features/         # Feature-specific components
   │   └── layouts/          # Layout components
   ├── hooks/
   │   ├── useAuth.ts        # Authentication hook
   │   └── useForm.ts        # Form handling hook
   └── utils/
       ├── api.ts            # API utilities
       └── validation.ts     # Validation helpers

8.2. Development Workflow

Setting Up Development Environment

1. Local Setup

   # Clone repository
   git clone https://github.com/your-username/daas-boilerplate.git
   
   # Install dependencies
   yarn install
   
   # Set up environment
   cp .env.example .env
   
   # Start development servers
   yarn dev
   

2. Development Tools

   {
     "devDependencies": {
       "eslint": "^8.0.0",
       "prettier": "^2.0.0",
       "husky": "^7.0.0",
       "lint-staged": "^12.0.0"
     },
     "scripts": {
       "lint": "eslint . --ext .ts,.tsx",
       "format": "prettier --write \"**/*.{ts,tsx,json,md}\""
     }
   }
   

Testing Guidelines

1. Unit Tests

   describe('UserService', () => {
     it('should create a new user', async () => {
       const user = await UserService.create({
         email: 'test@example.com',
         password: 'password123',
       });
       
       expect(user).toBeDefined();
       expect(user.email).toBe('test@example.com');
     });
   });
   

2. Integration Tests

   describe('Authentication Flow', () => {
     it('should authenticate user and return token', async () => {
       const response = await request(app)
         .post('/api/auth/login')
         .send({
           email: 'test@example.com',
           password: 'password123',
         });
       
       expect(response.status).toBe(200);
       expect(response.body.token).toBeDefined();
     });
   });

8.3. Documentation Standards

Code Documentation

1. Function Documentation

   /**
    * Processes a user subscription payment
    * @param userId - The ID of the user
    * @param planId - The ID of the subscription plan
    * @param paymentMethod - Payment method details
    * @returns Promise<PaymentResult>
    * @throws PaymentError if processing fails
    */
   async function processSubscription(
     userId: string,
     planId: string,
     paymentMethod: PaymentMethod
   ): Promise<PaymentResult> {
     // Implementation
   }
   

2. Component Documentation

   /**
    * Displays user profile information and allows editing
    * @component
    * @example
    * ```tsx
    * <UserProfile
    *   user={currentUser}
    *   onUpdate={handleUpdate}
    *   editable={true}
    * />
    * ```
    */
   interface UserProfileProps {
     /** The user object containing profile information */
     user: User;
     /** Callback function when profile is updated */
     onUpdate: (user: User) => void;
     /** Whether the profile is editable */
     editable?: boolean;
   }
   

API Documentation

1. Endpoint Documentation

   /**
    * @api {post} /api/users Create User
    * @apiName CreateUser
    * @apiGroup Users
    * @apiVersion 1.0.0
    *
    * @apiParam {String} email User's email
    * @apiParam {String} password User's password
    * @apiParam {String} [name] User's full name
    *
    * @apiSuccess {String} id User's unique ID
    * @apiSuccess {String} email User's email
    * @apiSuccess {String} name User's name
