Today we expand our knowledge to build pages that are more complex and utilize more features from the Next.js framework. In this article, we learn how to fetch initial data for our components on the server side. This way, we can take even more work off the client side. Fetching data First, let’s display some […]
In recent years, the popularity of client-side Single Page Applications skyrocketed, for various reasons. Following its principles, we build pages with the amount of interactivity that we didn’t have before. When using React to render the page the “regular” way, the server sends a blank page and the JavaScript files. By doing that, the browser […]
When writing Node.js code, we can approach tasks in many ways. While all of them might work fine, some perform better than others, and as developers, we should strive to make both easily readable and fast applications. In this article, we learn how to measure the performance of our code using Performance Hooks, also called […]
The Worker Threads give us quite exciting features when compared to, for example, child processes. In this article, we create our instances of the MessageChannel to communicate with the Worker Threads. Aside from that, we also share the data between them: it’s something that is not possible with child processes. Communicating using the MessageChannel There […]
The Node.js and JavaScript are often perceived as a single-threaded but in this series, we prove that it is not entirely true. Node.js creates threads when performing Input/Output operations. Not only that, but we can also create additional processes. While the above does not count yet as multithreading, in this article we begin to cover […]
After finding out that Node.js is in its nature single-threaded, we might think that all the cores of your processor are meant to go to waste, but this is not necessarily the case. In the previous part of this series, we prove that Node.js creates additional threads under the hood by itself. Not only that, […]
The Node.js environment and JavaScript is often identified with running just one task at a time, but this is not precisely the case. In this article, we go through the concept of multiple processes and spawn them using the child process module. Along the way, we learn how Node.js works under the hood in terms of […]
The world is a tough place – a lot of people out there to get you! While I might not teach you some martial arts and self-defense here, I hope to raise your level of awareness where it comes to malicious code. NPM happens to serve it every now and then! Identifying the problem Serving […]
JavaScript and the Node.js environment uses the Event Loop. In this article, we explore the idea of it and go through different phases that the event loop has. Although this series aims to present the usage of Node.js with TypeScript, this time we don’t get much of a chance to do it. In this part of […]
HTTPS seems to be everywhere now – it is a great time to go through its principals. Int his article we generate our certificate and use the HTTPS module from Node.js. With it, we can implement HTTPS in our local development environment. What problems does HTTPS solve and how? To see the advantages, let’s look […]
