1. Configuración de enrutamiento dinámico único

const clientRouter: RouteConfig = {
  path: '/client',
  component: Layout,
  redirect: 'noredirect',
  name: 'client',
  meta: {
    title: 'client',
    icon: 'patient',
    permission: "Pages_Client"

  },
  children: [
    {
      path: 'index',
      component: () => import('@/views/client/index.vue'),
      name: 'clientIndex',
      meta: {
        title: 'clientList',
        icon: 'patient',
        noCache: false,

      }
    },

  ]
}

2. Exportar todas las rutas dinámicas

import questionnaireRouter from './modules/questionnaireRouter'
import systemRouter from './modules/systemRouter'
import surveyRouter from './modules/surveyRouter'
import resourceRouter from './modules/resourceRouter'
import notificationRouter from './modules/notificationRouter'
import clientRouter from './modules/clientRouter'
import myRouter from './modules/myRouter'
import clientTrackingRouter from './modules/clientTrackingRouter'
import employeeRouter from './modules/employeeRouter'
import workflowRouter from './modules/workflowRouter'
import healthRouter from './modules/healthRouter'

/**
动态
*/
export const asyncRoutes: RouteConfig[] = [
  systemRouter,
  clientRouter,
  employeeRouter,
  myRouter,
  questionnaireRouter,
  surveyRouter,
  resourceRouter,
  notificationRouter,
  clientTrackingRouter,
  workflowRouter,
  healthRouter,

  {
    path: '*',
    redirect: '/404',
    meta: { hidden: true }
  },


]
