We are excited to share the release of our new Cost Calculator to showcase just how much the wrong APM provider can add to your cloud hosting costs (try it now). Observability is vital, but it comes with computational overhead that shares the same infrastructure as your application. This is compounded in typical Node.js APM tooling due to the internal workings of Node.js itself.
In the first part of this series, we built the asynchronous components of a much larger solution. Today, we will build the API interface that can be consumed in real-time.
Complex functionality can take a while to load. Users, in general, don't like to wait, so solutions must evolve. If you are already familiar with async/await in JavaScript, think of await as the place where blocking logically occurs. This forces the algorithm to wait, and technically, it's still synchronous code. Step functions allow long-running processes to run in the background asynchronously, so the logic does not get blocked and force people to wait.
You can find the issue by reading the stack trace after a program fails. A stack trace, however, only reveals the status of the application at the time of failure and not before the error was met. Logging packages can help with this. They provide specifics about the behavior of the program before the failure and transmit them to the location you specify, such as a file or a monitoring tool. Node.js has access to a wide variety of logging tools, but not all of them are made equal.
Playwright and Puppeteer have emerged as two of the most powerful end-to-end testing Node.js libraries. Their robust APIs make it easier to test the UI and workflows of sites and web applications. Although they are similar tools that offer comparable features, there are circumstances in which one is better to use than the other. In this article, we'll look at scenarios where it's better to use Playwright than Puppeteer for functionality and performance reasons.
Whether you're familiar with job schedulers or new to the concept, two popular libraries in the Node.js ecosystem stand out: Bull and Agenda. These libraries provide unique features and advantages when it comes to efficient job scheduling. Let's explore the ins and outs of Bull and Agenda! 🚀
For over a decade, NodeSource has developed and maintained a Node.js package repository that, has become the standard for production use globally. We are excited to announce some significant updates to this repo that include a large number of items related to user requests.
Automation testing has become a fundamental part of web development, and Playwright has emerged as one of the most powerful end-to-end testing tools. Thanks to its robust API and multi-browser support, it's easy to test sites and web apps. At the same time, Playwright can present some challenges if not approached correctly. Several pitfalls can compromise the effectiveness and performance of your tests, potentially leading to inaccurate results.
