Directivas Obligatorias

1. Multi-Tenant (OBLIGATORIO)

// SIEMPRE incluir tenant_id en headers de API
const api = axios.create({
  baseURL: import.meta.env.VITE_API_URL,
  headers: {
    'X-Tenant-Id': getCurrentTenantId(),
  },
});

// Hook para obtener tenant actual
const useTenant = () => {
  const { tenant } = useAuthStore();
  if (!tenant) throw new Error('No tenant context');
  return tenant;
};

4. TypeScript Estricto

// NUNCA usar any
// SIEMPRE tipar props y returns
// SIEMPRE usar interfaces para objetos

interface User {
  id: string;
  email: string;
  name: string;
  tenantId: string;
}

interface UserListProps {
  onSelect: (user: User) => void;
  filters?: UserFilters;
}

const UserList: React.FC<UserListProps> = ({ onSelect, filters }) => {
  // ...
};

Patrones de Implementacion

Store con Zustand

// src/features/users/stores/users.store.ts
import { create } from 'zustand';
import { devtools, persist } from 'zustand/middleware';
import { User, UserFilters } from '../types/users.types';
import { usersService } from '../services/users.service';

  // Actions
  fetchUsers: () => Promise<void>;
  selectUser: (user: User | null) => void;
  setFilters: (filters: Partial<UserFilters>) => void;
  createUser: (data: CreateUserDto) => Promise<User>;
  updateUser: (id: string, data: UpdateUserDto) => Promise<User>;
  deleteUser: (id: string) => Promise<void>;
}

export const useUsersStore = create<UsersState>()(
  devtools(
    persist(
      (set, get) => ({
        users: [],
        selectedUser: null,
        loading: false,

    return data.data;
  }

  async delete(id: string): Promise<void> {
    await api.delete(`${this.basePath}/${id}`);
  }
}

export const usersService = new UsersService();

Componente Lista

// src/features/users/components/UserList.tsx
import { useEffect } from 'react';
import { useUsersStore } from '../stores/users.store';
import { UserCard } from './UserCard';
import { Loading, EmptyState, ErrorState } from '@/shared/components';

        <Input
          {...register('role')}
          placeholder="Seleccionar rol"
        />
      </FormField>

      <div className="flex justify-end gap-2">
        <Button variant="outline" onClick={onCancel}>
          Cancelar
        </Button>
        <Button type="submit" loading={isSubmitting}>
          Guardar
        </Button>
      </div>

Pagina con Layout

// src/features/users/pages/UsersListPage.tsx
import { useState } from 'react';
import { PageHeader, Button, Modal } from '@/shared/components';
import { UserList } from '../components/UserList';
import { UserForm } from '../components/UserForm';

  const { createUser } = useUsersStore();

  const handleCreate = async (data: UserFormData) => {
    await createUser(data);
    setIsModalOpen(false);
  };

  return (
    <div className="space-y-6">
      <PageHeader
        title="Usuarios"
        description="Gestionar usuarios del sistema"
        actions={
          <Button onClick={() => setIsModalOpen(true)}>
            Nuevo Usuario
          </Button>
        }
      />

      <UserList />

      <Modal
