UniApp implements the expansion and usage skills of mini-game native components

Introduction:
UniApp is a cross-platform front-end development framework that supports the simultaneous development of applications for multiple mainstream mini-program platforms. In UniApp, we can improve the performance and user experience of the application by extending the native components of mini games. This article will introduce UniApp's techniques for expanding and using native components of mini-games, and give corresponding code examples for your reference.

1. Why expand the native components of mini games
The native components of mini games have better performance and richer functions, and can provide a better user experience. By extending the native components of mini games, we can directly call the functions of native components of mini games in UniApp, allowing the application to better interact with the native environment. At the same time, by expanding the native components of mini games, the performance of the application can be improved, and resource consumption and loading time can be reduced.

2. Methods of extending native components of mini-games in UniApp
UniApp supports extending native components of mini-games through cml-plugin-platform. The specific steps are as follows:

1. First, create a folder named cml-plugins in the root directory of the project.
2. Create a folder named platform-xxx under the cml-plugins folder, where xxx represents the name of the mini-game platform (such as wechat, qq).
3. Create a folder named component under the platform-xxx folder.
4. Create a folder named native-component under the component folder, and create a file named native-component.cml under the folder.

In the native-component.cml file, we can define a UniApp component to extend the functionality of the mini-game native component. For example, we can define a component named NativeButton, and the code is as follows:

<template>
  <view>
    <!-- 此处是UniApp组件的模板代码 -->
    <button @click="handleButtonClick">{{ buttonText }}</button>
  </view>
</template>

<script>
  export default {
    props: {
      buttonText: {
        type: String,
        default: 'Click Me'
      }
    },
    methods: {
      handleButtonClick() {
        // 此处是UniApp组件的事件处理函数代码
        uni.showToast({
          title: 'Button Clicked'
        })
      }
    }
  }
</script>

<style>
  /* 此处是UniApp组件的样式代码 */
</style>

3. Use the expanded mini-game native component in UniApp
Use the expanded mini-game native component in UniApp The components are very simple. We only need to introduce the expanded mini-game native components into the page file and use them in the same way as ordinary UniApp components. For example, we can use the extended NativeButton component in a page, and the code is as follows:

<template>
  <view>
    <!-- 此处是页面的模板代码 -->
    <NativeButton buttonText="Click Me"></NativeButton>
  </view>
</template>

<script>
  import NativeButton from '@/platform-xxx/component/native-component/native-component.cml'

  export default {
    components: {
      NativeButton
    }
  }
</script>

<style>
  /* 此处是页面的样式代码 */
</style>

Through the above code, we can introduce and use the extended NativeButton component in the page.
