import { createForm } from '@vielzeug/forge';
import { s } from '@vielzeug/spell';
import { createApi } from '@vielzeug/courier';
import { createLogger } from '@vielzeug/rune';

const log = createLogger('auth');
const api = createApi({ baseUrl: 'https://api.example.com' });

const LoginSchema = s.object({
  email: s.string().email(),
  password: s.string().min(8),
});

const form = createForm({
  defaultValues: { email: '', password: '' },
  schema: LoginSchema,
});

form.submit(async (values) => {
  const user = await api.post('/auth/login', { body: values });
  log.info('Login successful', { user });
});
