UniApp implements the expansion and usage guide of Jingdong Mini Program native components
In recent years, the development of mobile applications has been rapid, and cross-platform development tools have become more mature. UniApp, as one of the best, is efficient and The cross-platform feature is favored by more and more developers. In mobile application development, mini programs are becoming increasingly popular. In order to meet users' needs for native experience, we need to learn how to use UniApp to expand and use the native components of JD mini programs. This article will lead you step by step to achieve this goal, with detailed code examples.
- Preparation
First, we need to ensure that the uni-app cli tool has been installed, and then create a uni-app project. - Create JD Mini Program native component
Create a new directory in the pages directory of uni-app and name it jd-native-component. Create two files in this directory, namely jd-native-component.vue and jd-native-component.json.
jd-native-component.vue file content is as follows:
<template> <view> <nativeComponent></nativeComponent> </view> </template> <script> export default { components: { nativeComponent: { render(h) { return h('nativeComponent', { style: { height: '300px', width: '200px', backgroundColor: '#f2f2f2', color: '#ff0000', textAlign: 'center', lineHeight: '300px', }, on: { click: this.handleNativeClick, }, }, ['京东原生组件']) }, methods: { handleNativeClick() { uni.showToast({ title: '点击了京东原生组件', }) }, }, } }, } </script>
jd-native-component.json file content is as follows:
{ "usingComponents": { "nativeComponent": "/static/native-component" } }
The above code implements a A native component named nativeComponent has the functions of click events and text display. We can customize component styles and functions according to our needs.
- Configure the native component page
Configure the page path of the native component in the pages.json file of uni-app, and set the page navigation bar title. Modify as follows:
{ "pages": [ { "path": "pages/index/index", "style": { "navigationBarTitleText": "首页" } }, { "path": "pages/jd-native-component/jd-native-component", "style": { "navigationBarTitleText": "京东原生组件" } } ] }
- Add a jump link on the homepage
Add a jump link to the index.vue file on the homepage of uni-app so that we can click on the homepage to jump to JD.com Native component page. Modify as follows:
<template> <view class="content"> <button class="btn" @click="goToJdNativeComponent">跳转到京东原生组件</button> </view> </template> <script> export default { methods: { goToJdNativeComponent() { uni.navigateTo({ url: '/pages/jd-native-component/jd-native-component' }) }, }, } </script> <style> .content { display: flex; flex-direction: column; justify-content: center; align-items: center; height: 100vh; } .btn { width: 200px; height: 30px; background-color: #f2f2f2; border: none; outline: none; color: #333333; cursor: pointer; } </style>
The above code implements a function that jumps to the JD.com native component page after clicking on the homepage.
- Verification effect
Run the uni-app project in the terminal, then open the JD mini program development tool, scan the generated mini program preview QR code, and you can view it in the JD mini program The native components and functions we implemented.
Through the above steps, we successfully achieved the goal of extending and using the native components of JD Mini Program in UniApp. I hope that the introduction in this article can help everyone better apply UniApp and JD mini programs for mobile application development. If you have any questions or doubts, please leave a message for discussion.

To extend PHP function functionality, you can use extensions and third-party modules. Extensions provide additional functions and classes that can be installed and enabled through the pecl package manager. Third-party modules provide specific functionality and can be installed through the Composer package manager. Practical examples include using extensions to parse complex JSON data and using modules to validate data.

Generally speaking, uni-app is better when complex native functions are needed; MUI is better when simple or highly customized interfaces are needed. In addition, uni-app has: 1. Vue.js/JavaScript support; 2. Rich native components/API; 3. Good ecosystem. The disadvantages are: 1. Performance issues; 2. Difficulty in customizing the interface. MUI has: 1. Material Design support; 2. High flexibility; 3. Extensive component/theme library. The disadvantages are: 1. CSS dependency; 2. Does not provide native components; 3. Small ecosystem.

1.UncaughtError:Calltoundefinedfunctionmb_strlen(); When the above error occurs, it means that we have not installed the mbstring extension; 2. Enter the PHP installation directory cd/temp001/php-7.1.0/ext/mbstring 3. Start phpize(/usr/local/bin /phpize or /usr/local/php7-abel001/bin/phpize) command to install php extension 4../configure--with-php-config=/usr/local/php7-abel

UniApp has many conveniences as a cross-platform development framework, but its shortcomings are also obvious: performance is limited by the hybrid development mode, resulting in poor opening speed, page rendering, and interactive response. The ecosystem is imperfect and there are few components and libraries in specific fields, which limits creativity and the realization of complex functions. Compatibility issues on different platforms are prone to style differences and inconsistent API support. The security mechanism of WebView is different from native applications, which may reduce application security. Application releases and updates that support multiple platforms at the same time require multiple compilations and packages, increasing development and maintenance costs.

uniapp development requires the following foundations: front-end technology (HTML, CSS, JavaScript) mobile development knowledge (iOS and Android platforms) Node.js other foundations (version control tools, IDE, mobile development simulator or real machine debugging experience)

UniApp is based on Vue.js, and Flutter is based on Dart. Both support cross-platform development. UniApp provides rich components and easy development, but its performance is limited by WebView; Flutter uses a native rendering engine, which has excellent performance but is more difficult to develop. UniApp has an active Chinese community, and Flutter has a large and global community. UniApp is suitable for scenarios with rapid development and low performance requirements; Flutter is suitable for complex applications with high customization and high performance.
