Generating PDFs is one of those requirements that inevitably lands on a backend developer’s desk. Whether it’s generating dynamic invoices, downloadable reports, or shipping labels, the ability to convert data into a portable, uneditable document is a staple of enterprise applications.
Introduction # File uploads are a ubiquitous requirement for modern web applications, yet they remain one of the most significant attack vectors and performance bottlenecks in backend development. If you handle uploads incorrectly, you risk crashing your Node.js event loop with memory spikes or, worse, opening the door to Remote Code Execution (RCE) via malicious file payloads.
The landscape of backend development has shifted significantly as we wrap up 2025. While the “AI boom” has altered how we write code, the demand for robust, scalable network applications keeps Node.js at the top of the stack.
Introduction # In the landscape of 2025, Node.js remains the backbone of modern I/O-intensive backend architecture. However, the ecosystem has shifted. We are no longer just building simple CRUD APIs; we are building complex data processing pipelines, real-time aggregation services, and serverless functions where every millisecond of execution time translates directly to infrastructure costs.
