There are particular difficulties in getting NYC coverage from Node.js operating in Docker containers. This blog discusses the procedures needed to operate Node.js clusters in Docker and produce reliable code coverage reports.

We're thrilled to announce the release of N|Solid 6, the latest version of our powerful tool designed to elevate your production Node.js applications and services. Packed with advanced features and enhancements, N|Solid 6 offers unparalleled insights and operational control, making it the go-to solution for monitoring, diagnosing, and securing your critical Node.js applications.

AppSignal's Node.js package now offers out-of-the-box support for the AMQPlib package, enabling monitoring of inbound and outbound messages from popular Advanced Message Queuing Protocol (AMQP) brokers like RabbitMQ. In this article, we'll show you how to set up and use AppSignal to monitor your AMQP broker's performance.

Unit tests are essential to verify the behavior of small code units in a Node.js application. This leads to clearer design, fewer bugs, and better adherence to business requirements. That's why Test-Driven Development (TDD) and Behavior-Driven Development (BDD) have become so popular in the backend development community. In this tutorial, we'll dive into unit testing and understand why it's needed in your backend.

Welcome back to our exploration of Node.js' built-in test runner! In the previous article, we laid the groundwork for writing and running basic tests in your projects by exploring a few simple examples. In this installment, we'll dive into practical examples of how to use mocking, code coverage analysis, test hooks, and strategies for testing HTTP servers. These tools will help you write more comprehensive and reliable tests, ultimately leading to more robust Node.js applications. Let's get started!

The inclusion of a stable test runner in Node.js(version 18+) has generated significant debate in the community, given the abundance of established third-party testing frameworks. While its arrival naturally sparks comparisons to existing tools, this article won't focus on justifying its place in the ecosystem. Instead, we'll embark on a hands-on exploration of the test runner's core capabilities, from writing and executing tests to organization and customization features.

A well-known debate: tabs or spaces? Sure, we could set up a Google Form to collect this data, but where’s the fun in that? Let’s settle the debate, Kafka-style. We’ll use the new confluent-kafka-javascript client (not in general availability yet) to build an app that produces the current state of the vote counts to a Kafka topic and consumes from that same topic to surface them to a JavaScript frontend.

N|Solid Runtime, the OSS runtime that powers N|Solid Pro, is an innovative, lightweight runtime for Node.js applications. It offers real-time insights into performance, memory usage, and CPU consumption, giving developers unparalleled visibility into their code without requiring any modifications. In today’s software landscape, understanding your application's production behavior is crucial. With cloud-native architectures, microservices, and distributed systems, pinpointing issues is challenging.

In the world of natural language processing (NLP), the dream has always been to create systems that can understand, analyze, and generate human-like text. The good news is we are getting closer to this aspiration, thanks to innovations in artificial intelligence, particularly through platforms like OpenAI. In this article, we’ll explore text analysis with OpenAI, exploring the methodologies, tools, and metrics utilized to decipher the complex tapestry of human language. Let’s get started.

Data validation is essential to avoid unexpected behavior, prevent errors, and improve security. It can be performed both on a web page — where data is entered — and on the server, where the data is processed. In this tutorial, we'll explore data validation in the Node.js backend. Then, you'll learn how to implement it in Express using the express-validator library. Get ready to become a Node.js data validation expert!
