UniApp realizes the design and development method of homepage and navigation page

1. Introduction
UniApp is a cross-platform development tool built based on the Vue.js framework, which can compile a set of codes to produce multiple platform applications. In UniApp, the homepage and navigation page are two necessary pages when developing applications. This article will introduce how to design and develop these two pages in UniApp, and provide corresponding code examples.

2. Homepage design and development method

Page structure
The homepage of UniApp generally includes modules such as title bar, carousel, category navigation, and recommended products. Among them, the carousel chart is implemented using the swiper component, and the category navigation is implemented using the grid component.

The sample code is as follows:

<template>
  <view>
    <header></header>
    <swiper>
      <swiper-item v-for="(item, index) in bannerList" :key="index">
        <image :src="item.imageUrl"></image>
      </swiper-item>
    </swiper>
    <grid :list="categoryList"></grid>
    <recommend :list="recommendList"></recommend>
  </view>
</template>

<script>
  import header from '@/components/header.vue'
  import swiper from '@/components/swiper.vue'
  import grid from '@/components/grid.vue'
  import recommend from '@/components/recommend.vue'

  export default {
    components: {
      header,
      swiper,
      grid,
      recommend
    },
    data() {
      return {
        bannerList: [...],
        categoryList: [...],
        recommendList: [...]
      }
    }
  }
</script>

Style design
UniApp uses Vue's single file component, which can place HTML, CSS and JavaScript code in a .vue file middle. In the style design of the homepage, you can use flex layout to achieve adaptive and responsive layout of the page.

The sample code is as follows:

<style scoped>
  .container {
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
  }

  .swiper {
    width: 100%;
    height: 300px;
  }

  .grid {
    display: flex;
    flex-wrap: wrap;
    justify-content: space-between;
    align-items: center;
    width: 100%;
    margin-bottom: 20px;
  }

  .grid-item {
    width: 25%;
    text-align: center;
    padding: 10px;
  }

  .recommend {
    width: 100%;
    text-align: center;
  }
</style>

3. Navigation page design and development method

Page structure
UniApp’s navigation page generally contains a top title Modules such as columns, navigation bars, and content areas. Among them, the navigation bar is generally implemented using the tabbar component, and the content area is implemented using the tabbar tab page.

The sample code is as follows:

<template>
  <view>
    <header></header>
    <tabbar :active="activeIndex" @change="changeTab">
      <tabbar-item v-for="(item, index) in tabList" :key="index">
        <text>{{ item.title }}</text>
      </tabbar-item>
    </tabbar>
    <view class="content">
      <tabbar-panel v-for="(item, index) in tabList" :key="index" :index="index">
        <!-- 内容区域 -->
      </tabbar-panel>
    </view>
  </view>
</template>

<script>
  import header from '@/components/header.vue'
  import tabbar from '@/components/tabbar.vue'
  import tabbarItem from '@/components/tabbar-item.vue'
  import tabbarPanel from '@/components/tabbar-panel.vue'

  export default {
    components: {
      header,
      tabbar,
      tabbarItem,
      tabbarPanel
    },
    data() {
      return {
        activeIndex: 0,
        tabList: [
          { title: '首页' },
          { title: '分类' },
          { title: '购物车' },
          { title: '个人中心' }
        ]
      }
    },
    methods: {
      changeTab(index) {
        this.activeIndex = index
      }
    }
  }
</script>

Style design
Similar to the style design of the homepage, the style design of the navigation page can also use flex layout to achieve page adaption and responsive layout.

The sample code is as follows:

<style scoped>
  .container {
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
  }

  .content {
    width: 100%;
    height: calc(100% - 60px);
    overflow-y: auto;
  }
</style>
