2.2 Development Technology Stack for Baidu Mini Programs

The technology stack for Baidu Mini Programs is similar to that of other mini-program platforms, based on core front-end development technologies: HTML, CSS, and JavaScript. Baidu Mini Programs use their own development framework, which mainly consists of the following three parts:

WXML (WeiXin Markup Language): A markup language used to build the page structure, similar to HTML, for displaying interface content.

WXSS (WeiXin Style Sheets): Similar to CSS, responsible for defining page styles, including colors, fonts, layout, etc.

JavaScript: Used to handle page interactions and logic, managing user behavior and business data.

Developers can use these languages to implement page display, interaction logic, data acquisition, and display functions. Baidu Mini Programs also support data interaction with the backend, typically using API interfaces for data transmission.

2.3 Technical Architecture of Baidu Mini Programs

A typical Baidu Mini Program architecture consists of the following core components:

Frontend: Responsible for interface display and user interaction, primarily implemented using WXML and WXSS languages. The frontend can retrieve data transmitted from the backend and process interactions via JavaScript.

Backend: Responsible for handling user requests and providing data support. Backend servers typically use common web development technologies such as Node.js, PHP, Java, etc.

API Interfaces: The frontend and backend communicate via RESTful APIs or GraphQL to ensure real-time data updates and interactions.

Baidu Cloud Services: Baidu Mini Programs can leverage various Baidu Cloud services, such as object storage, databases, and AI services, to enhance the functionality and performance of the mini-program.

III. Best Development Practices for Baidu Mini Programs

To ensure the development of high-quality Baidu Mini Programs, developers should follow some best practices during the construction of the application to improve its stability, user experience, and maintainability.

3.1 Interface Design and User Experience Optimization

As lightweight applications, the interface design and user experience of mini-programs are crucial. Developers need to ensure that the mini-program meets user needs in both visual and interactive aspects.

Simple and Intuitive UI Design: The design of the mini-program should be as simple as possible, avoiding excessive functionality. Interface elements should be clearly arranged so that users can quickly find the functions they need.

Smooth Interactive Experience: Use smooth animation effects and responsive design to enhance the interactive experience, ensuring timely and accurate feedback after user operations.

Multi-Device Adaptation: Baidu Mini Programs need to be compatible with various devices, so design considerations should include different device resolutions and screen sizes, using flexible layout designs.

3.2 Performance Optimization and Loading Speed

The loading speed of a mini-program directly affects user retention and experience. Developers should focus on the following aspects:

Resource Optimization: Reduce the number of resources required for page loading, merge CSS and JavaScript files as much as possible, and minimize HTTP requests.

Image Compression and Format Optimization: Ensure images are appropriately sized, choose suitable formats such as WebP or JPG, and compress them to speed up loading.

Lazy Loading Technology: For resources that do not need to be loaded immediately on the page, use lazy loading, loading them only when the user needs them, to improve the initial screen loading speed.

3.3 Data Management and Interface Design

Baidu Mini Programs require extensive data interaction with backend servers, making reasonable data management and interface design crucial.

Interface Optimization: Use RESTful APIs or GraphQL for data transmission to ensure the simplicity and efficiency of the interfaces.

Caching Mechanism: Reasonably use caching mechanisms in the mini-program to reduce unnecessary network requests and improve response speed.

Data Security: Use encryption technology to protect user data and prevent data leaks. Especially when involving user privacy or payment functions, pay special attention to the secure transmission of data.

3.4 Security of Mini-Programs

The security of Baidu Mini Programs is a factor that cannot be ignored during development, especially when it involves sensitive operations such as payments and user information processing. Developers should ensure:

Data Encryption: All user-related data transmissions should be encrypted, such as using the HTTPS protocol to protect data security.

Permission Management: Strictly limit the permissions of the mini-program to ensure it only accesses necessary data and does not leak user privacy.

Review and Compliance: Ensure the content of the mini-program complies with Baidu's review requirements and national regulations to avoid removal due to violations.
