I've often heard the phrase: "Node.js is single-threaded," not only from Java and C# developers but from Node.js developers. However, since version 12, with the introduction of worker_threads, Node.js can now work with multiple threads. Many articles demonstrate this, but I'd like to share a video by master Erick Wendel, who shows us the multithreading capabilities in Node.js. https://lnkd.in/dphheR-v

🌟 Exciting News! 🌟 I’m thrilled to share that my second article is now live! 🎉 This time, I’ve dived deep into the fascinating world of Dependency Injection (DI), a concept that has transformed how I approach software development. In this article, I break down DI in a way that’s beginner-friendly, practical, and engaging. Whether you’re new to the topic or looking to sharpen your skills, I’ve packed it with real-world examples (including a MERN app with role-based authentication) and insights on how frameworks like NestJS make DI seamless. It’s been an incredible learning journey, and I hope this article can bring the same clarity and excitement about DI that I’ve experienced! I’d love for you to check it out and let me know what you think! 😊 #DependencyInjection #NestJS #NodeJS #WebDevelopment #LearningJourney #SoftwareEngineering #CodingCommunity #backend #backendDevelopment

In my weekly post, I share how I published my first simple Go library on pkg.go.dev. In this example, I create a basic library to validate Brazilian CNPJ numbers and demonstrate how to publish it on pkg.go.dev. It's exciting to see how easy it is to publish a library in Go and to watch the Go community continue to grow! If you find this library useful in your own Go project, please let me know—I’d be thrilled to know my work is helping others. https://lnkd.in/dA6Kh6Jz

When the codebase grows, it can become complex and unwieldy. Modularization can significantly simplify the development process. As the codebase expands, it can turn into a monstrous beast. That's where modularization shines, allowing you to organize business logic, functions, objects, and variables into well-defined modules. By leveraging CommonJS or ESM strategies, you can export these modules and keep your codebase clean, maintainable, and scalable.

Node.js → Node.ts 🚀 What a way to kick off 2025! 🎉 Just last week, this PR (https://lnkd.in/dBifiY5F) was merged, enabling node.js to support typescript by default! While still in the experimental phase and not yet released, this marks a huge step forward for the future of node.js development. What this change means: ✅ Create an index.ts file with TS syntax (type annotations included). ✅ Run it directly with node.js, no flags, no extra configuration. ✅ Node.js uses SWC to strip types and execute the code. I believe this move will significantly improve developers' productivity and streamline workflows by eliminating the need for tools like ts-node or complex setups to get typescript running. Native support for typescript in node.js will simplify the development process, reduce dependency overhead, and will make it easier for teams to adopt typescript in new and existing projects. With this advancement, developers can look forward to a more seamless and efficient typescript development experience. 💻💡 #NodeJS #NodeTS #TypeScript #JavaScript #WebDevelopment #SoftwareEngineering

🌟 Node.js Learning Update: Modules Explained! 🌟 Today, I dived into Node.js modules, a fundamental concept that enables better code organization and reuse. Here’s a summary of my key learnings: Modules in Node.js 1️⃣ Every Project Has a Main File: This is the starting point where the application begins execution. 2️⃣ What is require? The require() function is used to import modules into another file. Example: const demo = require("./demo.js"); Modules in Node.js are protected by default. Private variables and functions cannot be accessed directly unless explicitly exported. 3️⃣ Exporting Modules: To make variables or functions accessible in another file, we use module. exports. Examples: javascript // Option 1 module.exports = { calculateSum: calculateSum, name: name, gender: gender, }; // Option 2 (Shorthand) module.exports = { calculateSum, name, gender }; Types of Modules in Node.js 🔹 CommonJS Module (CJS) Default in Node.js. Example: module.exports = {}; Characteristics: Synchronous by nature. Operates in non-strict mode. 🔹 ES Module (ESM) A modern, standardized approach. Example: javascript Copy code export const calculateSum = (a, b) => a + b; import { calculateSum } from "./sum.js"; Characteristics: Asynchronous by nature. Operates in strict mode. Used by default in React.js and other modern frameworks. Switching to ES Modules in Node.js To enable ES Modules in a Node.js project: 1️⃣ Create a package.json file. 2️⃣ Add "type": "module" in the file. This learning clarified the differences between CommonJS and ES Modules, and how they work under the hood in Node.js. The hands-on practice made it even more rewarding! 🙌 Thank you, Akshay Saini 🚀, for simplifying complex concepts in Namaste Node.js and making learning so engaging. 🚀 Have you worked with Node.js modules?
