UniApp Expansion and Usage Guide for Implementing Quick Application Native Components

With the development of mobile applications, the importance of native components in mobile development cannot be ignored. As a cross-platform mobile application development framework, UniApp can not only easily develop iOS and Android applications, but also supports the introduction of native components to meet more complex needs. This article will introduce how to extend and use the native components of quick apps in UniApp and provide corresponding code examples.

UniApp is a development framework based on Vue.js, designed to enable a set of codes to run on multiple platforms at the same time. Quick App is a lightweight application solution jointly launched by mainstream mobile phone manufacturers, with faster startup speed and lower resource usage. Combining the two, you can use the native components of quick apps in UniApp to achieve more flexible and efficient functions.

First, we need to introduce the native components of the quick app into the UniApp project. Through the uni.loadSubPackage method, introduce the quick application package into App.vue:

uni.loadSubPackage({
    root: 'path/to/quickapp',
    success() {
        console.log('快应用包加载成功');
    },
    fail() {
        console.error('快应用包加载失败');
    }
});

After successful loading, we can use the native components of the quick application in UniApp. Suppose there is a native scrolling list component ScrollListView in the quick app, and we want to use this component in UniApp. First, create a ScrollListView component in the quick app:

// ScrollListView.ux
<template>
  <list view-type="scroll">
    <block for="{{list}}">
      <cell>{{item}}</cell>
    </block>
  </list>
</template>

<script>
  module.exports = {
    props: {
      list: {
        type: Array,
        value: []
      }
    }
  }
</script>

In UniApp, we create a custom component named QuickScrollListView to encapsulate the ScrollListView component of the quick app:

// QuickScrollListView.vue
<template>
  <view>
    <scroll-list-view :list="list"></scroll-list-view>
  </view>
</template>

<script>
  export default {
    props: {
      list: {
        type: Array,
        default: []
      }
    },
    components: {
      'scroll-list-view': 'path/to/quickapp/ScrollListView'
    }
  }
</script>

In In the above code, we use the component introduction method of uni-app to import the ScrollListView component of the quick app into the custom component QuickScrollListView. Now, we can use the QuickScrollListView component in UniApp:

// 页面中使用QuickScrollListView组件
<template>
  <view>
    <quick-scroll-list-view :list="list"></quick-scroll-list-view>
  </view>
</template>

<script>
  import QuickScrollListView from 'path/to/QuickScrollListView.vue';

  export default {
    components: {
      QuickScrollListView
    },
    data() {
      return {
        list: ['item1', 'item2', 'item3']
      };
    }
  }
</script>

Through the above code example, we successfully extended the quick app’s native component ScrollListView into UniApp and encapsulated it with the custom component QuickScrollListView. When using the QuickScrollListView component in a page, you can pass the list parameter to dynamically display the contents of the scrolling list.

To sum up, UniApp realizes the expansion and use of native components by introducing the native components of quick applications. By encapsulating the native components of quick apps in the form of custom components, developers can easily use the native capabilities of quick apps in UniApp. In this way, UniApp can also enjoy the advantages of native components while being cross-platform.

The above is the introduction to the expansion and usage guide of UniApp’s implementation of quick application native components. I hope it will be helpful to everyone. In this way, we can develop feature-rich and high-performance mobile applications with greater flexibility. If you are using UniApp for mobile application development, you might as well try introducing the native components of quick applications. I believe it will bring you a better development experience.
