vue2とvue3のvue-routerの違い

以下はvue3のルーターです

• createRouter
• createWebHashHistory
• RouteRecordRaw

vue3でインスタンスを新しくする必要はなく、createRouterを直接作成するだけです。

import { createRouter, createWebHashHistory, RouteRecordRaw } from 'vue-router'
import Home from '../views/Home.vue'
// 规定了数组元素类型是RouteRecordRaw，它可以在定义路由时进行友善地提示。
const routes: Array<RouteRecordRaw> = [
  {
    path: '/',
    name: 'Home',
    component: Home
  },
  {
    path: '/about',
    name: 'About',
    // route level code-splitting
    // this generates a separate chunk (about.[hash].js) for this route
    // which is lazy-loaded when the route is visited.
    component: () => import(/* webpackChunkName: "about" */ '../views/About.vue')
  }
]

const router = createRouter({
  history: createWebHashHistory(),
  routes
})

export default router

以下はvue2のルーターです

vue2では、新しいインスタンスが引き続き必要です

import Vue from 'vue';
import VueRouter, { RouteConfig } from 'vue-router';
import Home from '../views/Home.vue';

Vue.use(VueRouter);

const routes: RouteConfig[] = [
  {
    path: '/',
    name: 'Home',
    component: Home,
  },
  {
    path: '/about',
    name: 'About',
    // route level code-splitting
    // this generates a separate chunk (about.[hash].js) for this route
    // which is lazy-loaded when the route is visited.
    component: () => import(/* webpackChunkName: "about" */ '../views/About.vue'),
  },
];

const router = new VueRouter({
  routes,
});

export default router;
