One of the major developments in software design and delivery over the last few years has been a movement away from monolith applications towards microservices. One of the sticking points I’ve seen on numerous microservice applications is logging. There are some unique challenges with microservice logging that need to be addressed. In this article, we’ll look at how we can …
With the introduction of Node.js in 2009, it has become possible to use the JavaScript language while scripting server-side as well as client-side parts of an application or project. Earlier that was not possible since developers had to use different and multiple programming languages for both client and server-side scripting. Hence the invention of Node.js is still viewed as an …
Logging is an important topic in software development, especially if you need to analyze bugs and other unexpected events in your production environment. Implementing your logging often seems easy. But as you probably experienced yourself, logging is far more complex than it might seem. That’s why you can find lots of articles about it here on the blog. As an …
With the introduction of Node.js, it has become easier for application developers to create a fast, reliable, and scalable web application with much fewer lines of code. Node.js was created by Ryan Dahl in 2009 using the Google Chrome V8 JavaScript runtime environment. Software development is continuously evolving with the emergence of new technologies, trends, and programming languages. But with …
Node.js is an open-source framework that helps developers create dynamic web pages that can run across multiple platforms. It is built on Chrome V8, which means that it uses the same compiler or interpreter as Chrome. Node.js is used for full-stack, front-end, and back-end development. It simplifies real-time communication between the client and server. Node.js also has an event-driven architecture, …
What Is SLF4J and What are the Benefits of Using It? One of the most important aspects of developing an efficient system is to have clean, helpful logs that will help you understand what errors are being triggered, and what information is being processed.

Let’s begin with a little thought experiment. Imagine you’re responsible for the next release of your company’s flagship product, and today is the big day: you’re about to give a demo presentation for all the big shots in the company. The CTO is obviously there, since she’s your boss. The CEO is there as well, along with the VP of …
Today we’re going to look at performance tuning PostgreSQL. PostgreSQL is an advanced open source SQL database. Setting up the database is just the first step. With every table you add and every query you run, your databases will require maintenance and updates to ensure that they continue to run efficiently. Although PostgreSQL does make a lot of optimizations for you, there …

Picture this: you’re standing in the largest meeting room in your company. Behind you, a huge LED monitor. In front of you, all members of the C-suite. The CTO, your direct boss, is visibly nervous. The CEO looks interested and somewhat excited. The CFO looks happier than usual, though it probably has more to do with his very successful golf round …
I use performance monitoring tools primarily to find slow and buggy code. At the start of development, I typically use the tools more for finding software bugs. Once the codebase is at a relatively stable phase, then I shift my focus toward finding less performant code. Which is why I turn to tools like Retrace to help with profiling for …
