In the first part of this series, we toured performance APIs in Node.js. We discussed the capabilities of APIs and how they can diagnose slowdowns or network issues in your Node application. Now, in this concluding segment, we will embark on a practical journey, applying these performance hooks in a real-world scenario. You will understand how to effectively use these tools to monitor and enhance your application's performance. Let's dive in and see these concepts in action!

Node.js was introduced over 20 years ago and remains a popular choice for web application teams with over 30 million users. Sites such as Netflix, PayPal, and Uber continue to rely on Node.js to build and maintain their applications.

As software systems become more complex, navigating their inner workings has become increasingly difficult due to the evolution of more advanced architectures. While distributed systems, such as microservices and cloud-native architectures, offer benefits in scalability and agility, they also make it more challenging to pinpoint and resolve system issues. Traditional methods for tracking errors are often insufficient in these multifaceted environments.

Cron jobs are tasks set to run by themselves at certain times or intervals. They help with doing repetitive tasks automatically, like backing up data, sending emails, and updating systems. In Node.js, cron jobs can make tasks in applications run by themselves, making things more efficient and reliable. Node.js gives a good way to set these tasks through different libraries and tools.

CPU-bound tasks can grind your Node.js applications to a standstill, frustrating users and driving them away. You must master the art of profiling your application to pinpoint bottlenecks, and implement effective strategies to resolve any issues. In this guide, we'll explore various techniques to help you identify and fix the root causes of your Node.js performance issues. Let's get started!

Amazon Web Services (AWS) provides a vast ecosystem of products that make DevOps an absolute dream. Products like AWS Elastic Beanstalk have ready-made services for autoscaling, deployment, and logging (to name a few). However, teams may prefer to take a barebones approach and build incrementally - in which case AWS Elastic Compute Cloud (EC2) would be the preferred option.

AppSignal now supports Remix! With insights into the performance of Remix components like loaders and routing, AppSignal helps you refine your Remix application. This blog post will show you how to start monitoring your Remix application using AppSignal.

”Isn’t Observability something for Ops to worry about?” I’ve heard this response more than once when talking about how developers should learn OpenTelemetry. I wanted to write this piece to show you how important and how easy it is to learn observability from day one as a coder.
