In uni-app development, cross-platform debugging involves various tools and techniques, including Chrome DevTools, WeChat DevTools, Android Studio Logcat, and Xcode Console, which provide solutions for log output, performance monitoring, and style compatibility across different platforms. Conditional compilation is used to achieve unified log collection and processing for multiple platforms. When addressing style differences, unit conversion and Flex layout are employed for adaptation. Native API calls require encapsulated error handling, while performance optimization focuses on memory leaks and large data rendering. Platform feature detection dynamically retrieves environment information. Network request debugging includes interceptors and caching strategies. Complex interaction issues, such as gesture conflicts, require precise touch event control. The entire debugging process emphasizes handling platform differences and implementing unified management solutions.

Quick Apps and Baidu Mini Programs, as mainstream lightweight application ecosystems in China, require simultaneous adaptation in uni-app multi-platform development. Although both belong to lightweight applications, they differ in technical architecture and API design. Quick Apps are deeply optimized for mobile hardware platforms and use native component rendering, while Baidu Mini Programs rely on WebView technology and support more web features. The article provides a detailed comparison of their platform-specific differences, including API invocation methods, style adaptation, routing systems, lifecycle mapping, and more. It offers best practice recommendations for conditional compilation strategies and API encapsulation. For performance optimization, debugging techniques, common issue resolutions, build configuration differences, multi-platform component development, third-party library compatibility, and continuous integration strategies, the article presents concrete implementation solutions and code examples. These help developers efficiently achieve cross-platform adaptation.

When developing the H5 side in uni-app, special handling is required for browser-specific features, including responsive layout and screen adaptation—recommending the use of flex layout combined with vw/vh units. Routing is handled based on the browser's History API, requiring configuration of the routing mode in pages.json. Browser API differences necessitate conditional compilation or alternative solutions. Style compatibility requires handling different browser prefixes. Performance optimization can employ lazy loading of images, virtual lists, and Web Workers. Integration of third-party libraries like chart libraries (e.g., ECharts) and map libraries requires special handling. Security measures should focus on XSS protection, CSP policy settings, and validation of sensitive operations. Debugging and error monitoring can utilize vConsole and error reporting. Browser storage options include localStorage, IndexedDB, and Service Worker caching. Cross-origin issues can be resolved via development environment proxying, production environment CORS configuration, or JSONP. Mobile gestures require handling taps, long presses, and swipe direction detection.

Memory leak refers to the failure of a program to correctly release allocated memory, resulting in reduced available memory. In a Koa2 application, this can be caused by uncleaned timers, unclosed database connections, unbound event listeners, etc. Long-running server-side applications require special attention. Common scenarios include uncleaned timers and callbacks, unbound event listeners, etc. Detection tools can use Node.js built-in tools or the heapdump module. Prevention strategies include resource cleanup middleware, WeakRef and FinalizationRegistry, database connection pool management, cache management strategies, monitoring and alert systems, stress testing, code reviews, etc. A balance must be struck between performance optimization and memory management, such as using streaming to process large files, which is safer than fully loading them.

Static resource optimization is a key aspect of enhancing web application performance. Koa2, as a lightweight Node.js framework, provides a flexible middleware mechanism that efficiently handles static resource requests. Through reasonable optimization strategies, it can significantly reduce page load times, lower server pressure, and improve user experience. The article delves into static resource caching strategies, including strong caching and negotiated caching, as well as cache-busting techniques. It introduces methods for resource compression and bundling, such as Gzip, Brotli compression, and Webpack code splitting.

As a lightweight Node.js framework, Koa2 can become a performance bottleneck in single-process mode when handling high concurrency. By adopting cluster mode and load balancing techniques, it can fully utilize multi-core CPU resources to improve application throughput and stability. Node.js's cluster module allows the creation of child processes sharing the same port, where the master process manages worker processes—each worker being an independent V8 instance. Beyond the operating system's default round-robin strategy, fine-grained load control based on connection count and response time can be implemented. In cluster mode, attention must be paid to inter-process state sharing, which can be addressed using Redis for session sharing and event broadcasting mechanisms. Load balancers enable zero-downtime deployments, and a robust monitoring system is crucial for cluster management. Running clusters in Docker requires special handling, with common issues including port conflicts, file descriptor limits, and memory leak troubleshooting.
