GUIDs, or Globally Unique Identifiers, are 128-bit numbers that are generated to ensure uniqueness in various applications. They are also referred to as UUIDs, or Universally Unique Identifiers. The purpose of generating GUIDs is to provide a unique identification number that can be used to identify resources such as people, files, web pages, and even colors. Unlike regular registration numbers, which start counting at 1 and can overlap, guid generator in a way that ensures their uniqueness. The use of GUIDs has become increasingly popular in software development, where unique identification numbers are essential for efficient data management. There are different methods of generating GUIDs. One method is random generation, where the system's random-number generator is used to create a 128-bit number. Another method is time-based generation, where a GUID is created based on the current time. Additionally, hardware-based generation involves using a combination of hardware-based information, such as the MAC address, to generate a GUID. These methods ensure that GUIDs are unique and can be used for efficient data management. GUIDs have numerous applications in software development. They are commonly used in enterprise software development in languages such as C# and Java. In.NET Core, GUIDs are generated by creating a random number of 128 bits and performing a couple of bitwise operations. GUIDs are also used to identify hardware, software, and network resources.

Mastering Node.js: The Complete Guide for Developers

“Node.js is like a breath of fresh air in the world of web development, allowing developers to build fast and scalable applications with ease.” Node.js is a JavaScript runtime that allows you to build fast, scalable network applications. Some of the biggest companies in the world use Nodes, like Netflix, Uber, and PayPal. Node’s event-driven, non-blocking I/O model makes it lightweight and efficient. We will start with an example suppose you are a developer and you have been asked to develop a chat application capable of handling thousands of concurrent users, then Node.js is the perfect tool for that job. With its event-driven, non-blocking I/O model, Node.js makes it easy to build highly scalable applications that can handle a large number of connections.  

But where do you start? This comprehensive guide will serve as your roadmap, providing developers with all the knowledge they need to get started with Node.js development. 

Installing Node.js 

To get started with Node.js, the first thing developers need to do is install it. The easiest way is to go to the official Node.js website and download the installer for your system. There are also different methods to install Node.js like for Windows and Mac, developers can download an executable file that will guide them through the installation process. If developers are on Linux, they can install Node.js through their package manager (like apt or yum), or download the source code and compile it. 

Once the installation completes, open your terminal and run the command node -v to verify Node is installed. Developers should see the version number printed out, like v12.14.1. This confirms that Node.js is successfully installed on the developer system. Now they are ready to start building Node.js applications and exploring its powerful features. Developers are now prepared to begin. Developers must write all of their Node apps in.js files since Node.js operates by running JavaScript code outside of a browser. They can use the node command, such as node my_app.js, to run files directly. Node comes bundled with a (Node package manager) called npm, which makes it easy to install third-party packages/libraries to use in apps. Developers access npm through the npm command. Some of the most popular npm packages for Node are Express (for web servers), to install Express developers can run this command npm install express. To install Socket.IO (for real-time apps), developers can run the following commands npm install socket.io and MongoDB (for databases), developers can run the following commands npm install MongoDB. 

Developers’ first Node.js Application 

To build the first Node.js app, developers need to install Node.js on their machines. Then, open the terminal and run: 

Install Node.js with the official Node.js website (https://nodejs.org). 

Once installed, open the terminal or command prompt and run the following command to check your Node.js version: node -v 

Create and Run the Application 

Create a file named app.js in the developer’s desired directory. 

Open app.js in a code editor and add the following code: 

console.log (‘Hello World!’); 

Save the app.js file and go back to your terminal or command prompt. 

Navigate to the directory where the developer created app.js using the cd command. 

Run the following command to execute your Node.js application: node app.js 

Developers should see “Hello World!” printed in the console output, indicating that your application has successfully run. 

Node.js Core Modules: Utilizing the Built-in Functionality 

Node.js comes bundled with a variety of core modules that provide useful functionality. These built-in modules allow developers to do things like. 

File System Access: 

fs (File System): 

The “fs” module allows you to work with the file system, enabling file operations such as reading, writing, deleting, and modifying files. Developers can use this module to create, read, and write files, as well as perform operations on directories. For example, fs.readFile() – Reads data from a file. 

Reading a file using the fs module: 

JavaScript 

Copy code 

const fs = require(‘fs’); 

fs.readFile(‘file.txt’, ‘utf8’, (err, data) => { 

  if (err) { 

    console.error(err); 

    return; 

  console.log(data); }); 

HTTP Server 

The HTTP module allows you to create HTTP servers and make requests. Developers can use it to serve static files, build REST APIs, and more. For example: 

Const http = require(‘http’); 

const server = http.createServer((req, res) => { 

  res.statusCode = 200; 

  res.setHeader(���Content-Type’, ‘text/plain’); 

  res.end(‘Hello, World!’); 

}); 

server.listen(3000, () => { 

console.log(‘Server running on port 3000’); 

}); 

The HTTP module, combined with the fs module, allows you to serve static files like HTML, CSS, and JavaScript to build full web applications. 

Third-Party Modules: The NPM Registry 

The Node Package Manager (NPM) registry hosts over 1 million open-source Node.js packages developers can download and use in their projects. 

Some of the benefits of using NPM packages include: 

They are open-source, so developers are free to use and modify. 

Actively maintained and updated by the community. 

Solve common problems so the developers can avoid reinventing the wheel. 

Easy to install and integrate with developers’ apps. 

Node.js Frameworks and Tools 

Node.js has a strong ecosystem of tools and frameworks which help to accelerate the development process. The main players are listed below: 

Express: Express is the most popular web framework for Node.js. It facilitates the development of web apps and APIs. Express also offers middleware, routing, and other practical features to help you get up and running quickly. 

Koa: It is another web framework that uses newer JavaScript capabilities like async/awaits and is lighter than Express. 

Socket.IO: It provides real-time communication between developers’ Node.js servers and clients. It’s great for building chat apps, online games, and other interactive experiences. 

MongoDB: IT is a popular NoSQL database that pairs well with Node.js web applications. The Mongoose ODM (Object-Document Mapper) makes it easy to model your data and query MongoDB from Node.js. 

Yarn and npm are package managers that make it easy to add third-party libraries and dependencies to Node.js projects. 

These are some of the tools or frameworks for the development of Node.js. Node.js is a vast ecosystem and continues to grow rapidly. 

Conclusion: 

So, Node.js is an incredibly powerful tool for building fast and scalable network applications. With its event-driven, non-blocking I/O model, Node.js is efficient and lightweight. Throughout this comprehensive guide, we covered the basics of getting started with Node.js development, including setting up the development environment, frameworks, and tools. 

So, if you are looking to build Node.js applications and need a reliable development team, consider working with EOV. EOV is known for providing top Node.js developers who are experienced in building scalable and high-performance applications.

Dev Log Feb 7 2025 - The Stack

Ahoy. This is JFrame of 16Naughts in the first of what I hope will turn out to be a weekly series of developer logs surrounding some of our activities here in the office. Not quite so focused on individual games most of the time, but more on some of the more interesting parts of development as a whole. Or really, just an excuse for me to geek out a little into the void. With introductions out of the way, the first public version of our game Crescent Roll (https://store.steampowered.com/app/3325680/Crescent_Roll juuuust as a quick plug) is due out here at the end of the month, and has a very interesting/unorthodox tech stack that might be of interest to certain devs wanting to cut down on their application install size. The game itself is actually written in Javascript - you know, the scripting language used by your web browser for the interactive stuff everywhere, including here. If you've been on Newgrounds or any other site, they might call games that use it "HTML5" games like they used to call "Flash" games (RIP in peace). Unfortunately, Javascript still has a bit of a sour reputation in most developer circles, and "web game" doesn't really instill much confidence in the gamer either. However, it's turning more and more into the de-facto standard for like, everything. And I do mean everything. 99% of applications on your phone are just websites wrapped in the system view (including, if you're currently using it, the Tumblr app), and it's bleeding more and more into the desktop and other device spaces. Both Android and iOS have calls available to utilize their native web browsers in applications. Windows and Mac support the same thing with WebView2 and WebKit respectively. Heck, even Xbox and Nintendo have a web framework available too (even goes back as far as Flash support for the Wii). So, if you're not using an existing game engine like we aren't and you want to go multi-platform, your choices are either A) Do it in something C/C++ -ish, or now B) Write it in JS. So great - JS runs everywhere. Except, it's not exactly a first-class citizen in any of these scenarios. Every platform has a different SDK for a different low-level language, and none of them have a one-click "bundle this website into an exe" option. So there is some additional work that needs to be done to get it into that nice little executable package.

Enter C#. Everyone calls it Microsoft Java, but their support for it has been absolutely spectacular that it has surpassed Java in pretty much every single possible way. And that includes the number and types of machines that it runs on. The DotNet Core initiative has Mac, Windows, and Linux covered (plus Xbox), Xamarin has Android, and the new stuff for Maui brought iOS into the fold. Write once, run everywhere. Very nice. Except those itty bitty little application lifetime quirks completely change how you do the initialization on each platform, and the system calls are different for getting the different web views set up, and Microsoft is pushing Maui so hard that actually finding the calls and libraries to do the stuff instead of using their own (very strange) UI toolkit is a jungle, but I mean, I only had to write our stream decompression stuff once and everything works with the same compilation options. So yeah - good enough. And fortunately, only getting better. Just recently, they added Web Views directly into Maui itself so we can now skip a lot of the bootstrapping we had to do (I'm not re-writing it until we have to, but you know- it's there for everyone else). So, there you have it. Crescent Roll is a Javascript HTML5 Web Game that uses the platform native Web View through C#. It's a super tiny 50-100MB (depending on the platform) from not having to bundle the JS engine with it, compiles in seconds, and is fast and lean when running and only getting faster and leaner as it benefits from any performance improvements made anywhere in any of those pipeline. And that's it for today's log. Once this thing is actually, you know, released, I can hopefully start doing some more recent forward-looking progress things rather than a kind of vague abstract retrospective ramblings. Maybe some shader stuff next week, who knows.

Lemme know if you have any questions on anything. I know it's kind of dry, but I can grab some links for stuff to get started with, or point to some additional reading if you want it.
