DataV的使用

数据可视化平台

• 在Vue项目下进行组件库安装。

• npm安装

npm install @jiaminghi/data-view

• yarn安装

yarn add @jiaminghi/data-view

• main.js 引入

// 将自动注册所有组件为全局组件
import dataV from '@jiaminghi/data-view';
Vue.use(dataV);

{
  path: '/datav', name: 'datav', 
  component: () => import('../views/datav.vue')
},

import Vue from "vue"; 
import VueRouter from "vue-router";
import Home from "../views/Home.vue"; 

Vue.use(VueRouter);

  },
  {
    path: "/about", name: "About",
    component: () => import(/* webpackChunkName: "about" */ "../views/About.vue")
  },
  {
    //配置路径
    path: '/datav',
    name: 'datav',
    component: () => import('../views/datav.vue')
  },
]; 
const router = new VueRouter({
  //添加下面两行代码
  mode: 'history',
