使用vue实现一个手机端外卖饿了么app并且展示代码

这是一个比较大的项目，涉及到很多知识点，包括但不限于Vue框架、Vue Router、Vuex、Axios、ElementUI等。以下是一个简单的实现外卖饿了么app的示例代码：

App.vue

<template>
  <div id="app">
    <router-view></router-view>
  </div>
</template>

<script>
export default {
  name: "App",
};
</script>

<style>
#app {
  font-family: "Avenir", Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
}
</style>

router.js

import Vue from "vue";
import Router from "vue-router";

import Home from "./views/Home.vue";
import Cart from "./views/Cart.vue";
import Profile from "./views/Profile.vue";
import Search from "./views/Search.vue";

Vue.use(Router);

export default new Router({
  routes: [
    {
      path: "/",
      name: "home",
      component: Home,
    },
    {
      path: "/cart",
      name: "cart",
      component: Cart,
    },
    {
      path: "/profile",
      name: "profile",
      component: Profile,
    },
    {
      path: "/search",
      name: "search",
      component: Search,
    },
  ],
});

Home.vue

<template>
  <div class="home">
    <h1>Home Page</h1>
  </div>
</template>

<script>
export default {
  name: "Home",
};
</script>

<style>
.home {
  padding: 20px;
}
</style>

Cart.vue

<template>
  <div class="cart">
    <h1>Cart Page</h1>
  </div>
</template>

<script>
export default {
  name: "Cart",
};
</script>

<style>
.cart {
  padding: 20px;
}
</style>

Profile.vue

<template>
  <div class="profile">
    <h1>Profile Page</h1>
  </div>
</template>

<script>
export default {
  name: "Profile",
};
</script>

<style>
.profile {
  padding: 20px;
}
</style>

Search.vue

<template>
  <div class="search">
    <h1>Search Page</h1>
  </div>
</template>

<script>
export default {
  name: "Search",
};
</script>

<style>
.search {
  padding: 20px;
}
</style>

以上代码只是一个简单的示例，还需要自行添加代码实现功能，比如登录、注册、商品列表、购物车等。同时，还需要使用Mock数据模拟后端接口数据，使用Axios库进行数据请求。如果需要实现更多功能，还需要使用Vuex进行状态管理。
