This content details three common memory-leak patterns observed in long-running web scrapers, specifically after 968 Trustpilot runs. These leaks, which silently increase memory usage and cost, are often caused by producers fetching URLs faster than consumers can process them in asynchronous queues.
This article details the architectural logic behind building an asynchronous multi-API pipeline in Node.js for marketing automation. It addresses critical bottlenecks like API latency and rate limiting by advocating parallel processing over chronological data fetching, ensuring scalability for multi-client agencies.
Node.js, despite being single-threaded, is not immune to concurrency problems due to asynchronous operations, external services, and distributed systems. Understanding synchronization is essential for building scalable and reliable backend systems, preventing race conditions and data inconsistency.
This content explains the JavaScript Event Loop and how it enables asynchronous programming. It covers the fundamental concepts of how JavaScript handles non-blocking operations.
