uniapp modifies weex

With the popularity of mobile applications, cross-platform development frameworks are becoming more and more popular. Uniapp is a cross-platform development framework based on Vue.js, which can be written once and released to multiple application platforms at the same time. Weex is a cross-platform mobile development framework developed by Alibaba and also supports multi-platform publishing.

In actual development, we found that Uniapp and Weex are different in some aspects, and some functions are not provided or incomplete in Uniapp. However, because Uniapp's development model is relatively standardized, it is not easy for developers to make modifications by themselves. Therefore, we can do some development based on Weex and then integrate Weex components into Uniapp.

In this article, we will introduce how to integrate Weex components in Uniapp.

Step 1: Create a Weex component

To create a component in Weex, we need to first install Weex development tools, such as Weex Playground, Weex Devtools or CodeSandbox, etc. Here we take Weex Playground as an example.

In Weex Playground, we can create a new Weex file and write the following code:

<template>
  <div class="container">
    <div class="title">{{title}}</div>
    <div class="subtitle">{{subtitle}}</div>
    <div class="content">{{content}}</div>
  </div>
</template>

<script>
  export default {
    props: {
      title: {
        type: String,
        default: 'Title'
      },
      subtitle: {
        type: String,
        default: 'Subtitle'
      },
      content: {
        type: String,
        default: 'Content'
      }
    }
  }
</script>

<style>
  .container {
    padding: 20px;
    background: #f0f0f0;
  }

  .title {
    font-size: 20px;
    font-weight: bold;
    margin-bottom: 10px;
  }

  .subtitle {
    font-size: 16px;
    color: #666;
    margin-bottom: 10px;
  }

  .content {
    font-size: 14px;
    color: #333;
    line-height: 1.5;
  }
</style>

This is a very simple component, including a title, subtitle and content.

It should be noted that we must write components according to Weex's grammatical rules, otherwise errors will occur when integrated into Uniapp.

Step 2: Integrate Weex components into Uniapp

There are two ways to integrate Weex components into Uniapp: one is to integrate through Vue components; the other It is integrated through the mpvue plug-in.

Method 1: Integrate through Vue components

In Uniapp, we can integrate Weex components into the project through Vue components.

First, we need to copy the code of the Weex component into the Uniapp project, for example, save the component as a .vue file.

Next, in the page where the Weex component needs to be used, introduce the component:

<template>
  <div class="container">
    <weex-component :title="title" :subtitle="subtitle" :content="content"></weex-component>
  </div>
</template>

<script>
  import WeexComponent from '@/components/WeexComponent.vue';

  export default {
    name: 'MyPage',
    components: {
      WeexComponent
    },
    data() {
      return {
        title: 'This is title',
        subtitle: 'This is subtitle',
        content: 'This is content'
      }
    }
  }
</script>

In this example, we first introduce the .vue file of the Weex component.

Then, when the component is rendered, we use the tag and pass in the props data required by the component.

It should be noted that in this way, we need to manually copy the code of the Weex component into the Uniapp project.

Method 2: Integrate through the mpvue plug-in

mpvue is a small program development framework based on Vue.js, which can apply the development model of Vue.js to the development of small programs. . In Uniapp, we can also use the mpvue plug-in to integrate Weex components into the project.

First, we need to install the mpvue plug-in in the Uniapp project:

npm install --save-dev mpvue-weex

Then, in the page that needs to use the Weex component, introduce the mpvue-weex plug-in into the page file:

<template>
  <div class="container">
    <weex-component :title="title" :subtitle="subtitle" :content="content"></weex-component>
  </div>
</template>

<script>
  import MpWeex from 'mpvue-weex';
  import WeexComponent from '@/assets/WeexComponent.weex.vue';
  Vue.use(MpWeex);

  export default {
    name: 'MyPage',
    components: {
      WeexComponent
    },
    data() {
      return {
        title: 'This is title',
        subtitle: 'This is subtitle',
        content: 'This is content'
      }
    }
  }
</script>

In this example, we first introduce the Weex components we need to use.

Then, we introduce the mpvue-weex plug-in into the page and register it through the Vue.use() method.

Finally, we registered our Weex component in components.

It should be noted that in this method, we need to save the code of the Weex component in .weex.vue format and place it in the assets directory.

Summary

Through the above two methods, we can easily integrate Weex components into Uniapp. These methods can be used not only to integrate Weex components, but also to integrate components of other front-end frameworks.

Although Uniapp and Weex are different in some aspects, in this way, we can build a bridge between the two frameworks and achieve more flexible development.
