🔧 WORKFLOW

Example: Extract Duplicate Code

Before:

// UserController.ts
export class UserController {
  async createUser(req: Request, res: Response) {
    try {
      const user = await this.userService.create(req.body);
      res.status(201).json(user);
    } catch (error) {
      if (error instanceof ValidationError) {
        res.status(400).json({ error: error.message, details: error.details });
      } else if (error instanceof ConflictError) {
        res.status(409).json({ error: error.message });
      } else {
        console.error('Create user error:', error);
        res.status(500).json({ error: 'Internal server error' });
      }
    }
  }

  async updateUser(req: Request, res: Response) {
    try {
      const user = await this.userService.update(req.params.id, req.body);
      res.status(200).json(user);
    } catch (error) {
      if (error instanceof ValidationError) {
        res.status(400).json({ error: error.message, details: error.details });
      } else if (error instanceof ConflictError) {
        res.status(409).json({ error: error.message });
      } else {
        console.error('Update user error:', error);
        res.status(500).json({ error: 'Internal server error' });
      }
    }
  }

  async deleteUser(req: Request, res: Response) {
    try {
      await this.userService.delete(req.params.id);
      res.status(204).send();
    } catch (error) {
      if (error instanceof ValidationError) {
        res.status(400).json({ error: error.message, details: error.details });
      } else if (error instanceof ConflictError) {
        res.status(409).json({ error: error.message });
      } else {
        console.error('Delete user error:', error);
        res.status(500).json({ error: 'Internal server error' });
      }
    }
  }
