Introduction We had one API endpoint that generated a PDF report. It worked fine in testing. Then a customer ran it on a big dataset, and for about four seconds every other request to the server just hung. Health checks timed out, and the load balancer pulled the instance out of rotation. The database was […]
Introduction The first time I shipped a Node.js service to production, I ran docker images out of habit and stared at the number for a good ten seconds. The image was 1.1 GB, for an app whose actual code was only a few hundred kilobytes. It still worked, so I let it slide. Then the […]
Introduction Managing MongoDB users through command-line can be complex and time-consuming. Our MongoDB User Management Console provides a modern web-based GUI that makes database user administration simple and accessible for teams. What It Does This Node.js web application offers a complete solution for MongoDB user management with an intuitive interface that replaces complex command-line operations. […]
Introduction Serverless. A term that often confuses at first glance. Because servers are still there. You just don’t touch them. You don’t set them up, scale them, or patch them. That’s someone else’s job now — the cloud provider’s. And the most common example of this approach is AWS Lambda. For many developers, Lambda is […]
If you’ve ever worked on AWS Lambda, you will know that one word that buzzes every developer is – cold start. It’s like Thanos, an inevitable tax that you pay when Lambda spins up a fresh execution environment to handle a request. In Node.js, while the AWS documentation covers the basics (provisioned concurrency, minimizing package […]
Introduction As the complexity of my Node.js projects increased, handling larger codebases got more difficult. The scaling process seemed sluggish and error-prone due to manual dependency wiring, fragmented structure, and a lack of robustness. Keeping clean, orderly codebases while incorporating additional libraries or services was difficult. That’s when I explored NestJS, and it transformed my […]
In the dynamic landscape of distributed systems, communication between services is critical. As modern applications evolve, the need for efficient and scalable communication protocols becomes increasingly evident. One such protocol that has gained significant traction in recent years is gRPC. What is gRPC? gRPC, which stands for gRPC Remote Procedure Call, is an open-source RPC […]
Introduction: Why Containerization Is Important In modern software development, containerization has become a standard practice, particularly for Node.js applications and microservices. But why is containerization so valuable? Consistency Across Environments: One of the main challenges in development is environment inconsistencies. An application that runs on your local machine might behave differently in production due to […]
Introduction What is the Singleton Design Pattern? The Singleton Design Pattern limits the instantiation of a class to only one instance. This is beneficial when a single object or shared resource is required to coordinate actions throughout the system. It’s especially handy for managing shared resources or data across various instances of a class. For […]
