In our previous blog, we explored how to build a modern web server using BunJs and Prisma, integrating robust authentication mechanisms with JWT tokens. Now, it’s time to ensure our application is reliable and error-free through thorough testing. In this blog, we’ll dive into testing methodologies using Cucumber JS and Keploy, both are a powerful tools that streamline the testing process and enhance the quality of our application.

In this article, We will try to explore Token Bucket algorithm and its implementation in NodeJS for API Rate Limiting in very simple terms.

We all know what a "software" is, but then what is software testing or why is it even important? Let me answer your doubts- Software Testing is a process that involves evaluating software components to ensure they meet specified requirements and are defect-free. The main goal of software testing is to verify that the actual software matches the expected requirements, enhancing the product quality and customer satisfaction.

Network Telemetry, in simple terms, is like having a conversation with machines or systems located far away. It’s about collecting data from these distant sources to better understand how they’re performing. Think of it as a health check-up, but for machines or systems instead of people. This technology plays a crucial role in a variety of fields.

Have you ever come across a website that made you scroll over it again just to see the motions and transitions and made you GASP, thinking how hard it must be to create these amazing animations, One such animation I saw on keploy website, the parallax effect which made me go through there Developer section twice!

The adoption of eBPF (Extended Berkeley Packet Filter) has revolutionized high-performance applications, tracing, security, and packet filtering within the Linux kernel. Specifically, TC-BPF, a type of eBPF program attached to the Traffic Control (TC) layer, has emerged as a powerful tool for packet manipulation in both ingress and egress. This blog delves into the practical application of TC-BPF to redirect DNS queries in a Docker environment.

Logging is an integral part of software development, providing developers with valuable insights into the behaviour and performance of their applications. In the Go programming language, various logging libraries, such as the standard library’s log package or third-party options like logrus , zap and zerolog, facilitate the generation of log output.

In the vast landscape of cybersecurity, authentication stands as the guardian of digital fortresses, ensuring that only the right individuals gain access to sensitive information and services. Imagine you’re at the entrance of a top-secret facility, and you need to prove your identity to the security personnel. In the digital realm, this is precisely what authentication mechanisms do – they verify your identity before granting access.

Not long ago, I was handed a problem that’s no stranger to the world of programming: making asynchronous threads communicate effectively within the same process. Given the widespread nature of this issue, I expected to find an existing solution to resolve it. My search led me to the concept of message queue, which seemed promising for streamlining this communication challenge.

While working on an application that required executing a command to run a blocking program, such as a TCP/HTTP server, I encountered an interesting challenge. I needed a way to stop the application and its child processes when a signal was sent to the main program, such as SIGINT (Ctrl+C) or SIGTERM. This blog post shares my journey and the solutions I found to manage processes effectively in a Go application, focusing on Linux environments.
