我使用了Vue-CLI 3,并告诉我要使用vue-router。它在创建的routes.js中生成这种类型的Webpack导入语句。
// 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')
我继续创建四个视图。一些视图调用内部的组件。
Home.vue (Home page and default route at '/')
About.vue
Contact.vue
Photos.vue
我已在route.js中使About,Contact和Photos异步
import Home from './views/Home.vue';
/* name = named routes */
export const routes = [
{
path: '/',
component: Home,
name: 'home'
},
{
path: '/photo/:id',
// component: Photo,
component: () => import(/* webpackChunkName: "Photo" */ './views/Photo.vue'),
name: 'photo'
},
{
path: '/about',
component: () => import(/* webpackChunkName: "About" */ './views/About.vue'),
// component: About,
name: 'about'
},
{
path: '/contact',
// component: Contact,
component: () => import(/* webpackChunkName: "Contact" */ './views/Contact.vue'),
name: 'contact'
},
{
/* Wildcard path to catch all other paths */
path: '*',
redirect: '/'
}
];
当我进行构建时,Vue CLI确实会创建其他JS和CSS块(关于。[hash] .js等)。但是,当我加载Home路由时,这些其他块将根据Chrome的devtools进行加载,但是“响应”选项卡中也没有任何内容。然后,当我访问“关于”,“联系”或“照片”路线时,浏览器将加载这些块,但是现在“响应”选项卡中有一些内容。
异步是否按预期工作?
谢谢。
答案 0 :(得分:0)
我想我可能已经知道我的本地路线上的这些额外电话是什么。 Webpack有一个可以打开预取的配置。我猜Vue CLI或Webpack的默认设置是启用预取。
