Memory leaks are the "silent killers" of production environments. This article dives into the depths of the V8 engine, analyzing memory allocation and reclamation mechanisms, and demonstrates how to precisely locate and cure memory leaks using modern Node.js features from 2026.
Logs are the "black box" of an application. They not only record the system status but also serve as a crucial basis for troubleshooting, user behavior analysis, and security risk control. For Node.js developers, logging efficiently and building a complete log analysis system is a mandatory course for ensuring application stability.
Security is the lifeblood of an application. In Node.js development, common security vulnerabilities such as CSRF, XSS, broken access control, and SSRF can lead to data leaks, financial loss, or system compromise if not properly defended.
In the software development lifecycle, testing is a critical step for ensuring code quality and system stability. For Node.js applications, unit testing helps verify module correctness, while performance testing ensures the system remains reliable under load.
