// src/repositories/userRepository.ts
|
||||
import { db } from '../config/database';
|
||||
import { User } from '../models/user';
|

export class UserRepository {
|
||||
async findAll(): Promise<User[]> {
|
||||
return db.users.findMany({
|
||||
select: {
|
||||
id: true,
|
||||
name: true,
|
||||
email: true,
|

# Bolt Design System
|
||||
|
||||
async findById(id: number): Promise<User | null> {
|
||||
return db.users.findUnique({
|
||||
where: { id },
|
||||
select: {
|
||||
id: true,
|
||||
name: true,
|
||||
email: true,
|
||||
role: true,
|
||||
createdAt: true,
|
||||
updatedAt: true,
|
||||
},
|
||||
});

This document contains comprehensive design guidelines for creating beautiful, consistent, and production-ready user interfaces.
|
||||
|
||||
async findByEmail(email: string): Promise<User | null> {
|
||||
return db.users.findUnique({
|
||||
where: { email },
|
||||
select: {
|
||||
id: true,
|
||||
name: true,
|
||||
email: true,
|
||||
role: true,
|
||||
createdAt: true,
|
||||
updatedAt: true,
|
||||
},
|
||||
});
|
||||
}
|
||||
## Design Philosophy
|
||||
|
||||
async create(userData: CreateUserDto): Promise<User> {
|
||||
const hashedPassword = await hashPassword(userData.password);
|
||||
|
||||
return db.users.create({
|
||||
data: {
|
||||
name: userData.name,
|
||||
email: userData.email,
|
||||
password: hashedPassword,
|
||||
role: userData.role || 'USER',
|
||||
},
|
||||
select: {
|
||||
id: true,
|
||||
name: true,
|
||||
email: true,
|
||||
role: true,
|
||||
createdAt: true,
|
||||
updatedAt: true,
|
||||
},
|
||||
});
|
||||
}
|
||||
Create interfaces that are:
|
||||
|
||||
async update(id: number, userData: UpdateUserDto): Promise<User | null> {
|
||||
const data: any = {
|
||||
name: userData.name,
|
||||
email: userData.email,
|
||||
role: userData.role,
|
||||
};
|
||||
|
||||
// Only hash password if it's included in the update
|
||||
if (userData.password) {
|
||||
data.password = await hashPassword(userData.password);
|
||||
}
|
||||
|
||||
// Remove undefined values
|
||||
Object.keys(data).forEach(key => data[key] === undefined && delete data[key]);
|
||||
|
||||
return db.users.update({
|
||||
where: { id },
|
||||
data,
|
||||
select: {
|
||||
id: true,
|
||||
name: true,
|
||||
email: true,
|
||||
role: true,
|
||||
createdAt: true,
|
||||
updatedAt: true,
|
||||
},
|
||||
});
|
||||
}
|
||||
- **Professional and Beautiful** - Clean, modern aesthetics with attention to detail
|
||||
- **Production-Ready** - Fully featured and implementation-ready for real-world use
|
||||
- **Unique** - Distinctive visual style that avoids generic or cookie-cutter designs
|
||||
- **Consistent** - Cohesive visual language across all components and screens
|
||||
- **Accessible** - Usable by everyone, regardless of abilities or circumstances
|
||||
|
||||
async delete(id: number): Promise<boolean> {
|
||||
try {
|
||||
await db.users.delete({
|
||||
where: { id },
|
||||
});
|
||||
return true;
|
||||
} catch (error) {
|
||||
// If no rows were affected, user didn't exist
|
||||
if (error.code === 'P2025') {
|
||||
return false;
|
||||
}
|
||||
throw error;
|
||||
}
|
||||
}
|
||||
}
|
||||

### Error Handling Middleware
|
||||
|
||||
```typescript
|
||||
// src/middleware/errorHandler.ts
|
||||
import { Request, Response, NextFunction } from 'express';
|
||||
import { ValidationError, NotFoundError, AuthorizationError } from '../utils/errors';
|
||||
import logger from '../utils/logger';
|
||||
|
||||
export function errorHandler(
|
||||
err: Error,
|
||||
req: Request,
|
||||
res: Response,
|
||||
next: NextFunction
|
||||
) {
|
||||
// Log all errors
|
||||
logger.error({
|
||||
message: err.message,
|
||||
stack: err.stack,
|
||||
method: req.method,
|
||||
path: req.path,
|
||||
ip: req.ip,
|
||||
userId: req.user?.id,
|
||||
});
|
||||
|
||||
// Handle specific error types
|
||||
if (err instanceof ValidationError) {
|
||||
return res.status(400).json({
|
||||
status: 'error',
|
||||
message: err.message,
|
||||
code: 'VALIDATION_ERROR',
|
||||
});
|
||||
}
|
||||
|
||||
if (err instanceof NotFoundError) {
|
||||
return res.status(404).json({
|
||||
status: 'error',
|
||||
message: err.message,
|
||||
code: 'NOT_FOUND',
|
||||
});
|
||||
}
|
||||
|
||||
if (err instanceof AuthorizationError) {
|
||||
return res.status(403).json({
|
||||
status: 'error',
|
||||
message: err.message,
|
||||
code: 'FORBIDDEN',
|
||||
});
|
||||
}
|
||||
|
||||
// Handle unexpected errors
|
||||
const isDevelopment = process.env.NODE_ENV === 'development';
|
||||
|
||||
return res.status(500).json({
|
||||
status: 'error',
|
||||
message: 'Internal server error',
|
||||
code: 'SERVER_ERROR',
|
||||
...(isDevelopment && {
|
||||
detail: err.message,
|
||||
stack: err.stack,
|
||||
}),
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
### Authentication Implementation
|
||||
|
||||
```typescript
|
||||
// src/middleware/authenticate.ts
|
||||
import { Request, Response, NextFunction } from 'express';
|
||||
import jwt from 'jsonwebtoken';
|
||||
import { UserService } from '../services/userService';
|
||||
import { AuthorizationError } from '../utils/errors';
|
||||
|
||||
interface TokenPayload {
|
||||
userId: number;
|
||||
role: string;
|
||||
iat: number;
|
||||
exp: number;
|
||||
}
|
||||
|
||||
export function authenticate(
|
||||
requiredRoles: string[] = []
|
||||
) {
|
||||
return async (req: Request, res: Response, next: NextFunction) => {
|
||||
try {
|
||||
// Get token from authorization header
|
||||
const authHeader = req.headers.authorization;
|
||||
if (!authHeader || !authHeader.startsWith('Bearer ')) {
|
||||
throw new AuthorizationError('Authentication required');
|
||||
}
|
||||
|
||||
const token = authHeader.split(' ')[1];
|
||||
|
||||
// Verify token
|
||||
let payload: TokenPayload;
|
||||
try {
|
||||
payload = jwt.verify(
|
||||
token,
|
||||
process.env.JWT_SECRET!
|
||||
) as TokenPayload;
|
||||
} catch (err) {
|
||||
throw new AuthorizationError('Invalid token');
|
||||
}
|
||||
|
||||
// Check token expiration
|
||||
const now = Math.floor(Date.now() / 1000);
|
||||
if (payload.exp < now) {
|
||||
throw new AuthorizationError('Token expired');
|
||||
}
|
||||
|
||||
// Check role if required
|
||||
if (requiredRoles.length > 0 && !requiredRoles.includes(payload.role)) {
|
||||
throw new AuthorizationError('Insufficient permissions');
|
||||
}
|
||||
|
||||
// Get user and attach to request
|
||||
const userService = new UserService();
|
||||
const user = await userService.findById(payload.userId);
|
||||
|
||||
if (!user) {
|
||||
throw new AuthorizationError('User not found');
|
||||
}
|
||||
|
||||
// Attach user to request object
|
||||
req.user = user;
|
||||
|
||||
next();
|
||||
} catch (error) {
|
||||
next(error);
|
||||
}
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### Custom Error Classes
|
||||
|
||||
```typescript
|
||||
// src/utils/errors.ts
|
||||
export class ValidationError extends Error {
|
||||
constructor(message: string) {
|
||||
super(message);
|
||||
this.name = 'ValidationError';
|
||||
Object.setPrototypeOf(this, ValidationError.prototype);
|
||||
}
|
||||
}
|
||||
|
||||
export class NotFoundError extends Error {
|
||||
constructor(message: string) {
|
||||
super(message);
|
||||
this.name = 'NotFoundError';
|
||||
Object.setPrototypeOf(this, NotFoundError.prototype);
|
||||
}
|
||||
}
|
||||
|
||||
export class AuthorizationError extends Error {
|
||||
constructor(message: string) {
|
||||
super(message);
|
||||
this.name = 'AuthorizationError';
|
||||
Object.setPrototypeOf(this, AuthorizationError.prototype);
|
||||
}
|
||||
}
|
||||
|
||||
export class DatabaseError extends Error {
|
||||
constructor(message: string) {
|
||||
super(message);
|
||||
this.name = 'DatabaseError';
|
||||
Object.setPrototypeOf(this, DatabaseError.prototype);
|
||||
}
|
||||
}
|
||||
|
||||
export class ServiceError extends Error {
|
||||
constructor(message: string) {
|
||||
super(message);
|
||||
this.name = 'ServiceError';
|
||||
Object.setPrototypeOf(this, ServiceError.prototype);
|
||||
}
|
||||
}

## Code Examples
|
||||
|
||||
### Express.js Application Setup
|
||||
|
||||
```typescript
|
||||
// src/app.ts
|
||||
import express from 'express';
|
||||
import cors from 'cors';
|
||||
import helmet from 'helmet';
|
||||
import compression from 'compression';
|
||||
import rateLimit from 'express-rate-limit';
|
||||
import { errorHandler } from './middleware/errorHandler';
|
||||
import { notFoundHandler } from './middleware/notFoundHandler';
|
||||
import { requestLogger } from './middleware/requestLogger';
|
||||
import routes from './routes';
|
||||
|
||||
const app = express();
|
||||
|
||||
// Middleware
|
||||
app.use(helmet()); // Security headers
|
||||
app.use(cors()); // CORS handling
|
||||
app.use(compression()); // Response compression
|
||||
app.use(express.json()); // Parse JSON bodies
|
||||
app.use(express.urlencoded({ extended: true })); // Parse URL-encoded bodies
|
||||
app.use(requestLogger); // Log all requests
|
||||
|
||||
// Rate limiting
|
||||
const limiter = rateLimit({
|
||||
windowMs: 15 * 60 * 1000, // 15 minutes
|
||||
max: 100, // 100 requests per IP
|
||||
standardHeaders: true,
|
||||
legacyHeaders: false,
|
||||
message: 'Too many requests from this IP, please try again later',
|
||||
});
|
||||
app.use(limiter);
|
||||
|
||||
// Routes
|
||||
app.use('/api', routes);
|
||||
|
||||
// Error handling
|
||||
app.use(notFoundHandler);
|
||||
app.use(errorHandler);
|
||||
|
||||
export default app;
|
||||
```
|
||||
|
||||
### API Route Definition
|
||||
|
||||
```typescript
|
||||
// src/routes/userRoutes.ts
|
||||
import { Router } from 'express';
|
||||
import { UserController } from '../controllers/userController';
|
||||
import { UserService } from '../services/userService';
|
||||
import { UserRepository } from '../repositories/userRepository';
|
||||
import { authenticate } from '../middleware/authenticate';
|
||||
import { validateRequest } from '../middleware/validateRequest';
|
||||
import { createUserSchema, updateUserSchema } from '../validation/userSchemas';
|
||||
|
||||
const router = Router();
|
||||
const userRepository = new UserRepository();
|
||||
const userService = new UserService(userRepository);
|
||||
const userController = new UserController(userService);
|
||||
|
||||
router.get('/',
|
||||
authenticate(['ADMIN']),
|
||||
(req, res, next) => userController.getUsers(req, res, next)
|
||||
);
|
||||
|
||||
router.get('/:id',
|
||||
authenticate(),
|
||||
(req, res, next) => userController.getUserById(req, res, next)
|
||||
);
|
||||
|
||||
router.post('/',
|
||||
validateRequest(createUserSchema),
|
||||
(req, res, next) => userController.createUser(req, res, next)
|
||||
);
|
||||
|
||||
router.put('/:id',
|
||||
authenticate(),
|
||||
validateRequest(updateUserSchema),
|
||||
(req, res, next) => userController.updateUser(req, res, next)
|
||||
);
|
||||
|
||||
router.delete('/:id',
|
||||
authenticate(['ADMIN']),
|
||||
(req, res, next) => userController.deleteUser(req, res, next)
|
||||
);
|
||||
|
||||
export default router;
|
||||
```
|
||||
|
||||
### Dependency Injection Setup
|
||||
|
||||
```typescript
|
||||
// src/config/container.ts
|
||||
import { Container } from 'inversify';
|
||||
import { TYPES } from './types';
|
||||
import { UserController } from '../controllers/userController';
|
||||
import { UserService } from '../services/userService';
|
||||
import { UserRepository } from '../repositories/userRepository';
|
||||
import { DatabaseConnection } from '../config/database';
|
||||
import { Logger } from '../utils/logger';
|
||||
|
||||
const container = new Container();
|
||||
|
||||
// Infrastructure
|
||||
container.bind<DatabaseConnection>(TYPES.DatabaseConnection).to(DatabaseConnection).inSingletonScope();
|
||||
container.bind<Logger>(TYPES.Logger).to(Logger).inSingletonScope();
|
||||
|
||||
// Repositories
|
||||
container.bind<UserRepository>(TYPES.UserRepository).to(UserRepository).inSingletonScope();
|
||||
|
||||
// Services
|
||||
container.bind<UserService>(TYPES.UserService).to(UserService).inSingletonScope();
|
||||
|
||||
// Controllers
|
||||
container.bind<UserController>(TYPES.UserController).to(UserController).inSingletonScope();
|
||||
|
||||
export { container };
|
||||
```
|
||||
|
||||
### Testing Example
|
||||
|
||||
```typescript
|
||||
// src/services/__tests__/userService.test.ts
|
||||
import { UserService } from '../userService';
|
||||
import { UserRepository } from '../../repositories/userRepository';
|
||||
import { ValidationError, NotFoundError } from '../../utils/errors';
|
||||
|
||||
// Mock the repository
|
||||
jest.mock('../../repositories/userRepository');
|
||||
|
||||
describe('UserService', () => {
|
||||
let userService: UserService;
|
||||
let userRepository: jest.Mocked<UserRepository>;
|
||||
|
||||
beforeEach(() => {
|
||||
userRepository = new UserRepository() as jest.Mocked<UserRepository>;
|
||||
userService = new UserService(userRepository);
|
||||
});
|
||||
|
||||
afterEach(() => {
|
||||
jest.clearAllMocks();
|
||||
});
|
||||
|
||||
describe('create', () => {
|

// Arrange
|
||||
const userData = {
|
||||
name: 'John Doe',
|
||||
email: 'john@example.com',
|
||||
password: 'password123',
|
||||
};
|
||||
|
||||
userRepository.findByEmail.mockResolvedValue(null);
|
||||
userRepository.create.mockResolvedValue({
|
||||
id: 1,
|
||||
...userData,
|
||||
role: 'USER',
|
||||
createdAt: new Date(),
|
||||
updatedAt: new Date(),
|
||||
});
|
||||
|
||||
// Act
|
||||
const result = await userService.create(userData);
|
||||
|
||||
// Assert
|
||||
expect(userRepository.findByEmail).toHaveBeenCalledWith(userData.email);
|
||||
expect(userRepository.create).toHaveBeenCalledWith(userData);

## Best Practices
|
||||
|
||||
### Code Structure Best Practices
|
||||
|
||||
- Keep files small and focused on a single responsibility
|
||||
- Use consistent naming conventions across the codebase
|
||||
- Group related functionality together
|
||||
- Separate business logic from infrastructure concerns
|
||||
- Maintain clear dependency boundaries
|
||||
|
||||
### API Design Best Practices
|
||||
|
||||
- Use nouns for resource endpoints
|
||||
- Keep URLs clean and simple
|
||||
- Use HTTP methods appropriately
|
||||
- Return appropriate status codes
|
||||
- Document all endpoints
|
||||
|
||||
### Security Best Practices
|
||||
|
||||
- Never trust client input
|
||||
- Implement proper authentication and authorization
|
||||
- Follow the principle of least privilege
|
||||
- Keep dependencies up to date
|
||||
- Run regular security scans
|
||||
|
||||
### Performance Best Practices
|
||||
|
||||
- Implement appropriate caching
|
||||
- Optimize database queries
|
||||
- Use async/await for I/O operations
|
||||
- Monitor and optimize bottlenecks
|
||||
- Consider pagination for large data sets
|
||||
|
||||
### Testing Best Practices
|
||||
|
||||
- Write tests at multiple levels (unit, integration, system)
|
||||
- Use test doubles (mocks, stubs, spies) appropriately
|
||||
- Aim for high code coverage
|
||||
- Test happy paths and edge cases
|
||||
- Incorporate testing into the development workflow
