Hello there! 👋🏻

I've made the decision to create a channel where I can share my thoughts, programming tips, and tricks. Initially, it was created for my own benefit, but if you've stumbled upon it – welcome!

❓So, whoami?
I go by the name Tony. I'm a Node.js developer with a background in C# and Python. My career began with C#. However, after gaining several years of experience, I made the switch to JavaScript and TypeScript.

❓Why Node.js?
• JS Everywhere: It's easy to develop applications of any kind and utilize JavaScript on both the frontend and backend. This approach promotes code reusability and a consistent development experience. To be honest, I'm not particularly fond of frontend development; the majority of my projects are server-side.
• Rapid Prototyping: Node.js is often the preferred choice for rapid prototyping and building MVPs due to its quick setup and flexibility.
• Scalability: Node.js can handle a large number of concurrent connections with relatively low resource usage. This makes it well-suited for constructing scalable applications, such as real-time chat apps or online gaming platforms.

❓What about TypeScript?
I always use TypeScript when starting a new project. It helps prevent type-related bugs and enhances code quality.

❓What Will You Find Here?
You can expect to find a collection of my thoughts, hacks, and intriguing discoveries. I explore GitHub daily in search of fresh and captivating projects.

❓Current Focus
Presently, I'm engrossed in the development of a personal project, which I plan to discuss in a separate post. I've got a bunch of different ideas, and my aim is to implement 'em one by one.
Even though I'm not exactly a frontend enthusiast, I've taken the plunge into learning React.js and Next.js. And who knows, down the line, I might even explore React Native since a few of my ideas involve crafting mobile apps.

If you come across anything intriguing here in the future, feel free to share it with your friends 😉

🚀 Boosting Node.js Performance: Quick Tips and Tricks 🚀

Hey Node.js enthusiasts! 🌟
If you're looking to optimize the performance of your applications and make them lightning-fast, you're in the right place. Let's dive into some quick tips and tricks to give your projects a performance boost! ⚡️

1. Use Async/Await
Embrace async/await for handling asynchronous operations. This modern syntax simplifies code readability and ensures efficient handling of non-blocking operations.

2. Monitoring and Profiling
Don't forget about profiling tools. It helps identify performance bottlenecks for optimization. Tools like Node.js built-in profiler, heapdump, or third-party options like v8-profiler can help pinpoint memory-hungry code.

3. Minimize Blocking Operations
Avoid synchronous operations that block the event loop, causing slowdowns. Utilize worker threads or offload CPU-intensive tasks to separate processes.

4. Optimize Database Queries
Fine-tune your database queries by indexing frequently used fields and avoiding excessive data retrieval. Tools like Mongoose can help manage MongoDB queries effectively.

5. Leverage Caching
Implement caching mechanisms like Redis to store frequently accessed data in memory. This reduces the need to fetch data from the database repeatedly, improving response times.

6. Use Compression
Enable Gzip compression to reduce the size of responses sent to clients, resulting in faster data transfer over the network.

7. Use Load Balancing
Implement load balancing to distribute incoming traffic across multiple Node.js instances, enhancing overall performance and scalability.

8. Use HTTP/2 and SSL/TLS
Upgrade to HTTP/2 for multiplexing multiple requests over a single connection. Implement SSL/TLS to enhance security and improve performance due to browser optimizations.

Let's talk about comfort 😌

A developer always wants to have comfortable workplace. Yes, and who wouldn't want a cozy IT zen in the heart of coding? That's why I want to share with you one incredibly useful feature to achieve perfect harmony ☯️

Personally, I've always been surprised by the lack of a built-in feature to automatically change the Windows color scheme depending on the time of day. A light theme during the day, a dark theme at night. It sounds quite logical, but apparently not for Microsoft 🤨

How long did it take them to finally implement a full-fledged dark theme? They don't seem to be in a hurry to add the ability to easily switch between themes either 🐢

But don't despair! There are developers who are not procrastinating, but taking action. They have created a simple but incredibly useful application - Auto Dark Mode. I think there is no need to describe in detail why it is worth your attention 🌙

Just try:

Abandon the password and make your server more secure? Easy! 🛡

After a long timeout, I decided to write a post on cybersecurity. Today, let's talk about something important - using private keys instead of traditional usernames and passwords for SSH connections. After all, security is not just a word; it's the foundation of a reliable IT system.

🔑 What is a Private Key?
A private key is a unique form of authentication that uses cryptographic methods. Unlike standard usernames and passwords, a private key is a long sequence of characters that is nearly impossible to crack.

🔒 Why Is It Safer?

🔸 Difficulty of Breach: A private key is generated using complex algorithms and is much longer than standard passwords, making it extremely challenging to hack.
🔸 No Reuse: Unlike passwords, often reused across platforms, each private key is unique to a specific session or device.
🔸 Physical Security: The private key is stored on the user's device, reducing risks associated with remote attacks.
🔸 Two-Factor Authentication: Using a private key along with a password provides an additional layer of security.

🔧 How Does It Work?
When you establish an SSH connection, the server verifies the authenticity of the private key before granting access. This ensures a secure and protected connection between your device and the server.

🌐 Conclusion
Switching to using private keys for SSH is a step towards enhancing the security of your systems. It reduces risks associated with phishing, data interception, and other forms of cyberattacks.

💡 Remember, security starts with us. Stay vigilant and choose reliable data protection methods!

Yesterday I realized that when setting up a server I constantly waste time trying to remember where I saved the instructions for setting up SSL. To make life easier for myself and you, I am publishing it here.

So today we'll cover how to quickly and easily set up SSL on your Ubuntu server using Nginx. This is a crucial step in securing your site, as it encrypts data between the server and the user.

1️⃣ Install Certbot:

sudo apt update && sudo apt install certbot python3-certbot-nginx

2️⃣ Obtain an SSL Certificate:

sudo certbot --nginx -d yourdomain.com -d www.yourdomain.com

3️⃣ Verify Configuration:

sudo nginx -t
sudo systemctl reload nginx

4️⃣ Check auto-renewal service:

sudo systemctl status certbot.timer

Effective Parallel Task Management in JavaScript

Hi there! 🖖

I suddenly decided to share my experience with p-limit. This library allows you to control the number of concurrently running asynchronous operations, which is especially useful when working with resource-intensive or rate-limited APIs.

❓ Why is this important?
When working with a large number of asynchronous tasks, such as API requests or I/O operations, executing all tasks simultaneously can lead to system overload or exceeding API limits. To avoid this situation and improve application performance, it is necessary to limit the number of parallel tasks.

Overall, the project documentation is very clear. I will just show you the tip of the iceberg.

Installation is done as usual, through any package manager. I prefer pnpm, but here is an example for npm:

npm install p-limit

For CommonJS projects:

npm install p-limit@3.1.0

Suppose we have an array of asynchronous tasks and want to limit the execution to 2 parallel tasks:

const pLimit = require('p-limit');

const limit = pLimit(2); // Limit to 2 concurrent tasks

const tasks = [
  async () => { /* Task 1 */ },
  async () => { /* Task 2 */ },
  async () => { /* Task 3 */ },
  async () => { /* Task 4 */ }
];

const limitedTasks = tasks.map(task => limit(task));

Promise.all(limitedTasks).then(results => {
  console.log(results);
});

Yes, it's that simple to solve this task 🙂

I want to highlight an important point. The package does not support CJS starting from version 4.0.0. So either install the older version - 3.1.0, or migrate your project to ESM.
