A database is a collection of information carefully organized into a system. The technology that allows us to organize data and represent the information necessary for an information system is called Database Management System (DBMS). A DBMS is software that encapsulates the data of a database and provides us with a centralized way to store, retrieve, edit, persist, and perform other operations on it. Let’s define some of the main properties of a DBMS:...
In the world of servers, the term “reverse proxy” often comes up. But what exactly is a reverse proxy and what is it useful for? To start, let’s first discuss the concept of a proxy. A proxy is a server that accepts connections from clients who have configured their network settings to use the proxy server. When a client establishes a connection to a server, their requests are routed through the proxy server....
Single Page Applications (SPAs) are modern web applications that are built to provide a seamless and faster user experience. Unlike traditional web applications, SPAs do not require a full page reload whenever a user interacts with the application. Instead, SPAs load the application code (HTML, CSS, JavaScript) only once and then dynamically update the content as users interact with the application. In the past, when browsers were less capable and JavaScript performance was poor, every page in a web application was fetched from the server with each click....
When it comes to integrating different services in your code, utilizing webhooks is a common practice. But what exactly is a webhook? A webhook is essentially a POST request handler that awaits a call and performs a specific task once triggered. Here’s an example to illustrate how webhooks work. Let’s say I use Paddle as a platform to sell my Bootcamp course on bootcamp.dev. Every time someone signs up for the course, my webhook is called, providing me with JSON data that includes the customer’s email, name, and the purchased product....
RFCs, or Request for Comments, are publications from the technology community. In several blog posts, I mention “this technology is defined in RFC xxxx” or “see RFC yyyy for the nitty-gritty details.” But what exactly is an RFC? An RFC stands for Request for Comments. While the term RFC can be used in various contexts, traditionally in the world of the Internet, it refers to a publication written by engineers and computer scientists for other professionals working within the Internet sphere....

It manifests as a feeling of inadequacy or the belief that one is not as competent or talented as others perceive them to be. This syndrome can have a significant impact on self-confidence and personal growth, especially in professional fields such as software development. Here are a few scenarios that often trigger imposter syndrome:...
Introduction to pnpm, a drop-in replacement for npm that helps reduce disk space usage. In a previous blog post, I discussed the issue of having huge node_modules folders and how it doesn’t necessarily have to be a bad thing. However, finding ways to reduce our hard drive consumption is always a plus, especially considering that newer computers in 2019 are shipping with smaller SSD drives. One way to address this is by centralizing the storage of library code and sharing it across all the projects we work on....
Serverless is a term that refers to a specific way of running programs without the need to manage your own server. Instead, you create a function and store it on a cloud server, which gives you a URL to call whenever you want to execute that function. The beauty of serverless computing is that someone else takes care of server management, scaling, and security, eliminating the need for you to worry about tasks like kernel updates or transitioning to the latest long-term support (LTS) release of your Linux distribution....
In today’s world of web development, having a strong understanding of JavaScript is essential. JavaScript lies at the heart of everything, from building interactive websites to creating full-blown applications. It powers server-side runtimes like Node.js, and serves as infrastructure with tools like npm and npx. Quite simply, you can use JavaScript for almost anything. Having a solid grasp of JavaScript can greatly enhance your career prospects. But with so many JavaScript courses available, how do you choose the best one?...
Every HTML document needs to start with a Document Type Declaration, commonly known as a doctype. This declaration informs the browser about the version of HTML used in the webpage. To ensure compatibility and proper rendering, it is essential to include the doctype declaration as the first line of an HTML document. The doctype declaration for HTML5 is: <!DOCTYPE html> This declaration tells the browser that the document is an HTML5 document....
