四.项目开发
1.vue3.0项目环境
node.js安装 vue脚手架安装 npm install -g @vue/cli 创建项目 vue create 项目名
2. 项目初始化
通过各种调试将页面变为空白原始状态
3.项目分辨率响应式分析与实施
4.项目分辨力响应式创建
下载 lib-flexble npm install --save lib-flexible
修改flexible.js文件 修改refreshRem函数
function refreshRem(){
var width = docEl.getBoundingClientRect().width;
// if (width / dpr > 540) {
// width = 540 * dpr;
// }
// var rem = width / 10;
//修改 最小值400 最大值2560
if (width / dpr<400) {
width = 400 * dpr;
}
else if(width / dpr>2560){
width = 2560 * dpr;
}
//设置成24份 1920px设计稿 1rem 就是80px
var rem = width / 24;
docEl.style.fontSize = rem + 'px';
flexible.rem = win.rem = rem;
}
修改main.js文件
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
//引用插件
import "lib-flexible/flexible.js"
createApp(App).use(store).use(router).mount('#app')
vscode安装该插件
将Root Font Size设置为80

8.后台接口创建express介绍
9.后台express路由创建
1.安装express npm install --save express
1.创建Server文件夹，创建index.js
在index.js中设置代码
let express=require("express");
let app=express();
//引用路由文件
let chartOne=require("./router/one")
let chartTwo=require("./router/Two")
let chartThree=require("./router/Three")
let chartFour=require("./router/Four")
//使用中间件来配置路由
app.use("/one",chartOne)
app.use("/two",chartTwo)
app.use("/three",chartThree)
app.use("/four",chartFour)
app.listen(8888)
创建四个文件
let express=require("express");
let router=express.Router()
router.get("/data",(req,res)=>{
res.send({
msg:"我是one的路由地址"
})
})
module.exports=router;

10.api接口的创建
创建的json文件全部放在mock文件夹中
//one.json
{
"chartData":[
{"title":"冰箱","num":1827},
{"title":"洗衣机","num":342},
{"title":"电视机","num":541},

}
}
//one.js 其他四个js也如此修改
let express=require("express");
let router=express.Router()
let oneData=require("../mock/one.json")
router.get("/data",(req,res)=>{
res.send({
