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

UniApp is a cross-end development tool based on the Vue framework. By using UniApp, we can easily compile a project into multiple platform applications at the same time, including applets, H5, App, etc. The Bytedance mini program is a unique form of mini program with its own native components and unique development methods. This article will introduce how to implement the expansion and usage techniques of ByteDance applet native components in UniApp, and provide corresponding code examples.

1. Extension of native components

The native components of ByteDance applet refer to those components that cannot achieve similar effects through simple simulation implementation and are only supported in native Components used on the platform. In UniApp, we can extend the native components of the Bytedance applet in two ways.

1.1 Using plug-ins

UniApp supports the use of plug-ins to extend the native components of ByteDance mini programs. We can configure the plug-in information in the manifest.json file of the UniApp project and directly reference the native components provided by the plug-in in the project. For example, we can reference the native component of the ByteDance applet by configuring the "byte-tiktok" field in the uni.setting.json file.

"byte-tiktok": {
  "provider": "toutiao",
  "path": "uni-tiktok"
}

Then use the native components of the ByteDance applet in the page, which can be used just like the built-in components of UniApp. You only need to add the plug-in name before the component name.

<template>
  <byte-tiktok-component />
</template>

1.2 Using custom components

If the required native component is not provided in the plug-in, or we want to implement a native component in a custom way, we can use UniApp's custom component Function to extend the native components of ByteDance applet. We can use the uni.createNativeComponent method to create a custom component and use it in the page.

const ByteTikTokComponent = uni.createNativeComponent('byte-tiktok-component', {
  style: {
    width: '100rpx',
    height: '100rpx'
  },
  props: {
    src: {
      type: String,
      default: ''
    }
  },
  methods: {
    play() {
      // 实现原生组件的播放逻辑
    }
  }
})
export default {
  components: {
    ByteTikTokComponent
  }
}

<template>
  <byte-tiktok-component :src="videoSrc" />
</template>

2. Tips for using native components

When using the native components of the Bytedance applet, we need to pay attention to some usage tips to ensure that the components can run normally.

2.1 Introducing the JavaScript library of the Bytedance applet

In order to use the native components of the Bytedance applet, we need to introduce the JavaScript library of the Bytedance applet into the UniApp project. We can place the JavaScript library of the ByteDance applet in the static directory of the UniApp project and introduce it into the page.

<script src="/static/tt.js"></script>

2.2 Handling of Mini Program Jump Logic

The native components of Bytedance Mini Program may contain some logic that needs to jump to other pages. At this time, we need to pay attention to handling the Mini Program Jump logic. When clicking on a native component, we can jump to other pages by calling the uni.navigateTo or uni.switchTab method.

methods: {
  handleClick() {
    // 跳转到其他页面
    uni.navigateTo({
      url: '/pages/other-page'
    })
  }
}

3. Sample code

The following is a sample code that shows how to implement the expansion and usage skills of ByteDance applet native components in UniApp.

<template>
  <view>
    <scroll-view class="scroll-view" scroll-y="true">
      <text class="title">扩展字节跳动小程序原生组件</text>
      <byte-tiktok-component :src="videoSrc" />
      <button class="button" @click="handleClick">跳转到其他页面</button>
    </scroll-view>
  </view>
</template>

<script>
const ByteTikTokComponent = uni.createNativeComponent('byte-tiktok-component', {
  style: {
    width: '100rpx',
    height: '100rpx'
  },
  props: {
    src: {
      type: String,
      default: ''
    }
  },
  methods: {
    play() {
      // 实现原生组件的播放逻辑
    }
  }
})

export default {
  components: {
    ByteTikTokComponent
  },
  data() {
    return {
      videoSrc: 'video.mp4'
    }
  },
  methods: {
    handleClick() {
      // 跳转到其他页面
      uni.navigateTo({
        url: '/pages/other-page'
      })
    }
  }
}
</script>

<style>
.scroll-view {
  height: 100%;
}

.title {
  font-size: 32rpx;
  text-align: center;
  margin-top: 50rpx;
}

.button {
  width: 200rpx;
  height: 80rpx;
  line-height: 80rpx;
  background-color: #f60;
  color: #fff;
  text-align: center;
  margin: 50rpx auto;
}
</style>

The above is an introduction to how to implement the expansion and usage techniques of ByteDance mini program native components in UniApp. By using plug-ins and custom components, we can easily use and extend the native components of the ByteDance applet. I hope this article can help you develop ByteDance applets in UniApp.
