项目情况
我使用的是express做为服务器框架,只需要调用后台API接口获得数据,然后把数据渲染成html就可以了。最好能使用一套模板渲染前后端的数据,也就是模板和某些简单组件可以同构。
服务端渲染vue组件,使用 vue-server这个插件。他的用法和vue差不多。这样做的目的是首屏服务端渲染,提升页面展示速度。
开发组件
因为需要让服务端也能使用,单.vue文件的开发方式我目前是没有找到可以让node读取的方式,所以就暂时放弃了。还有下面这种写死组件名字的方式也不太合适
Vue.component('my-component', { /* ... */ }) //这样写需要引入Vue,但是前后端的Vue不是一个东西
所以我选择了只输出一个个简单组件对象的方式,如下 modal.js
为什么template模板要直接写在里面呢?
答:因为会有2种引入方式,前端是可以预编译好的没有问题,但是后端调用 import ‘XXX.html’ 这句话就可能执行不了。
输出组件
#index.js 输出组件的文件import modal from './component/modal/modal'exports.modal = modal
前端使用组件
import Vue from 'vue'import { picker, modal, toast, alert, preloader, indicator, actions, pullToRefresh, infiniteScroll} from '../src/index' //使用前端的Vue定义组件和指令的名称Vue.component('picker',picker);Vue.component('modal',modal);Vue.component('toast',toast);Vue.component('alert',alert);Vue.component('preloader',preloader);Vue.component('indicator',indicator);Vue.component('actions',actions)Vue.directive('pull-to-refresh',pullToRefresh)Vue.directive('infinite-scroll',infiniteScroll)
这样前端就可以正常使用这个组件了
后端使用组件
import { picker, modal, toast, alert, preloader, indicator, actions, pullToRefresh, infiniteScroll} from '../src/index' let vueServer = require('vue-server') //服务端Vuelet Vue = new vueServer.renderer();//页面模板let tpl = fs.readFileSync(config.PATH_WEBAPP + '/states/index/template.html', 'utf-8');//vue实例vm = new Vue({ replace: false, template: tpl, components : { picker : picker, modal : modal, toast : toast, alert : alert }, data: { }});//渲染好html的事件vm.$on('vueServer.htmlReady', function (html) { res.render('layout', {server_html:html}); //这个html就是vue服务端渲染好的,然后可以通过ejs或者其他模板引擎输出到layout中。});
ok 这种通用组件写法只适合比较简单的项目。比较适合写一次绑定生成页面元素的组件,比如列表,布局这种组件。

The alt attribute is an important part of the tag in HTML and is used to provide alternative text for images. 1. When the image cannot be loaded, the text in the alt attribute will be displayed to improve the user experience. 2. Screen readers use the alt attribute to help visually impaired users understand the content of the picture. 3. Search engines index text in the alt attribute to improve the SEO ranking of web pages.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML is used to build web page structure; 2. CSS is used to beautify the appearance of web pages; 3. JavaScript is used to achieve dynamic interaction. Through tags, styles and scripts, these three together build the core functions of modern web pages.

Setting the lang attributes of a tag is a key step in optimizing web accessibility and SEO. 1) Set the lang attribute in the tag, such as. 2) In multilingual content, set lang attributes for different language parts, such as. 3) Use language codes that comply with ISO639-1 standards, such as "en", "fr", "zh", etc. Correctly setting the lang attribute can improve the accessibility of web pages and search engine rankings.
