The solution

Technological Integration and Innovation

• Backend Technology Stack Integration: We chose Node.js + TypeScript + Express to build the backend, leveraging TypeScript's strong typing features to enhance code robustness and utilizing modular design to improve system scalability.
• Frontend Framework Optimization: We adopted Uniapp and VueJs for cross-platform development, combined with targeted optimizations based on mini-program characteristics to ensure a balance between performance and user experience.

Data Security and Consistency

• Data Synchronization Strategy: We implemented a Redis caching mechanism to accelerate data retrieval, combined with distributed locking to ensure data consistency, addressing the challenges of high concurrency.
• Payment Security Enhancement: We adopted HTTPS for encrypted transmission, integrated the official WeChat Pay SDK, and implemented multiple verification mechanisms to ensure the security and reliability of the payment process.
• This mini-program has integrated a refund function, enabling one-click refunds in the backend.
  
  
• Currency Handling: We implemented a currency conversion function that can convert different currencies into Chinese yuan, effectively simplifying the complexity of multi-currency management involved in global operations.

Performance Optimization and User Feedback

• Loading Performance Improvement: We utilized techniques such as lazy loading of images and resource compression to shorten page load times and enhance user-perceived speed.
• Error Handling Mechanism: We built a global error capture and handling system that categorizes and processes exceptions, providing clear user prompts and enhancing system reliability.

Middleware Development and Integration

• Middleware Design Principles: Adhering to the principle of single responsibility, we ensure that middleware functions are clear and efficient, reducing system complexity.
• Integration and Testing Processes: Implementing automated testing and Continuous Integration/Continuous Deployment (CI/CD) ensures that middleware is integrated into the system quickly and stably, with comprehensive testing validating its effectiveness.

AWS Cloud Deployment and Management

• Selecting Appropriate AWS Cloud Services: Based on business requirements, we choose suitable AWS cloud services, such as EC2, RDS, S3, etc.
• Configuring Server Resources Reasonably: To ensure system performance, we allocate server resources appropriately.
• Adopting AWS Security Services: Utilizing AWS security services such as IAM, VPC, WAF, etc., ensures system security.
  

Mini-Program: Dual Experience in Ads & Promotions
