Web Application Development Checklist
This document comprehensively outlines the best practices framework for building highly available, secure, and efficient web services. At the security level, it emphasizes enabling modern encryption protocols such as TLS 1.3, HSTS, and OCSP Stapling, and strictly configuring CSP, Rate Limiting, and firewall rules to defend against XSS, DDoS, and brute-force attacks. In terms of network and system configuration, it recommends optimizing TCP congestion control algorithms, minimizing port exposure, disabling root password login, and reducing risks through SELinux and file permission controls. From an operations perspective, it is necessary to establish robust monitoring and alerting, snapshot backup, and automated scaling mechanisms to ensure rapid recovery of business continuity during failures or traffic spikes. In the DevOps workflow, static code analysis, unit testing, and containerized deployment should be integrated via CI/CD pipelines, leveraging Docker and Kubernetes for flexible scaling. The core of application development lies in eliminating underlying defects such as memory leaks, deadlocks, and SQL injection to ensure code quality. Additionally, attention must be paid to user experience, including responsive layout, multi-language and timezone support, and PWA compatibility, while strictly adhering to global and local compliance requirements such as GDPR and the Personal Information Protection Law, thereby achieving dual assurance of technical architecture and business value.
