How to Troubleshoot ReDoS in Node.js

The Node.js Production Troubleshooting Series addresses challenging production issues, particularly ReDoS, which causes applications to appear frozen due to regex backtracking. This article explains the causes of ReDoS, demonstrates how to simulate it, and provides a step-by-step diagnostic process using the yCrash tool to identify and resolve performance degradation linked to regex patterns.

How to Troubleshoot Memory Leaks in Node.js

The Node.js Production Troubleshooting Series addresses complex production issues, focusing initially on memory leaks. These occur when applications retain unnecessary object references, leading to increased memory usage. The series provides insight into causes, simulations, diagnostic tools like yCrash, and step-by-step methods for identifying and resolving memory leaks in applications.
