How to implement food delivery and dish recommendation in uniapp

With the development of mobile Internet, the food delivery industry is booming. In this era, people pay more attention to fast, convenient and efficient lifestyles, so food delivery has become a popular industry. How to use uniapp development tools to implement food delivery and dish recommendations? Below we will introduce it in detail and give corresponding code examples.

1. Overview

uniapp is a cross-platform development framework that can develop iOS, Android and small programs at the same time. uniapp is based on the Vue.js framework and can run on multiple platforms by writing a set of code. In the process of realizing meal delivery and dish recommendation, we can make full use of the cross-platform features provided by uniapp to integrate the needs of multiple platforms.

2. Implement the catering takeout function

1. Create a uniapp project

First, we need to create a uniapp project. Open HBuilderX (uniapp cross-platform development tool), select a new project, select a template, and click OK. Choose the corresponding template (such as native template, etc.) according to your own needs.

2. Writing a takeaway page

In the uniapp project, we can create multiple pages to implement the takeout function. For example, you can create a page to display a list of restaurants, another page to display restaurant details, and a page to display shopping cart information, etc.

3. Implementing the takeout function

On the restaurant list page, we can get the restaurant list by calling the backend interface and display it on the page. Click on the restaurant to jump to the restaurant details page, displaying the restaurant's detailed information and menu list. On the menu list page, users can select dishes and add them to the shopping cart. On the shopping cart page, users can view the information of the selected dishes, modify the quantity or delete them.

When implementing the takeout function, you need to use the components and API provided by uniapp. For example, use the uni-list component to display a list of restaurants, use the uni-NavigateTo method to implement page jumps, and use uni-Toast to prompt users for operation results, etc.

3. Realize the dish recommendation function

1. Recommend based on the user’s personal preferences

By analyzing the user’s ordering history and dish evaluation, we can Recommend similar types of dishes based on personal preferences. In uniapp, you can use storage to record the user's ordering history and make recommendations based on the restaurants and dishes that the user is interested in.

2. Recommendation based on big data analysis

By analyzing and mining a large number of user ordering data, we can use machine learning algorithms to predict user preferences and recommend corresponding of dishes. In uniapp, you can call the backend interface to obtain user dish evaluation data, and make recommendations to users through algorithm analysis.

When specifically implementing the dish recommendation function, it is necessary to combine the background database and algorithm implementation, and display the recommended dish list through the request interface and data binding method provided by uniapp.

4. Summary

Through the above steps, we can implement meal delivery and dish recommendation functions in uniapp. Taking advantage of the cross-platform features of uniapp, it can run on multiple platforms to meet the diverse needs of users. At the same time, combined with the background database and algorithm, more accurate dish recommendation services can be carried out.

Code example:

Restaurant list page:

<template>
  <view>
    <canvas class="content"></canvas>
    <button @click="goToRestaurantDetail">餐厅详情</button>
  </view>
</template>

Restaurant details page:

<template>
  <view>
    <text>{{ restaurant.name }}</text>
    <text>{{ restaurant.address }}</text>
    <button @click="addToCart">加入购物车</button>
  </view>
</template>

Dishes list page:

<template>
  <view>
    <uni-list>
      <uni-card
        v-for="(dish, index) in dishes"
        :key="index"
      >
        <text>{{ dish.name }}</text>
        <text>{{ dish.price }}</text>
        <button @click="addToCart(dish)">加入购物车</button>
      </uni-card>
    </uni-list>
  </view>
</template>

Shopping cart Page:

<template>
  <view>
    <uni-list>
      <uni-card
        v-for="(dish, index) in cart"
        :key="index"
      >
        <text>{{ dish.name }}</text>
        <text>{{ dish.price }}</text>
        <button @click="modifyQuantity(dish, 1)">加</button>
        <text>{{ dish.quantity }}</text>
        <button @click="modifyQuantity(dish, -1)">减</button>
        <button @click="removeFromCart(dish)">删除</button>
      </uni-card>
    </uni-list>
  </view>
</template>
