I'd like to share a code refactoring from a JavaScript FrontEnd project to ReactJS, using hooks (UseState, UseEffect, UseContext, and UseSearchParams) and UseLocation, BrowserRouter, and link (React-Router-Dom) into components.

🚀 Esta é uma pergunta que frequentemente surge ao implementar APIs com bancos de dados, usar ORMs de terceiros, criar nossos próprios ORMs, criar consultas SQL... Neste repositório, iniciei um estudo sobre o desempenho de acesso a bancos de dados em Golang! Comparamos três abordagens comuns: consulta SQL única, CRUD DAO e GORM ORM. Todas testados com PostgreSQL. Os resultados destacam diferenças significativas em eficiência e uso de recursos. Vale ressaltar que, em todos os casos, devemos nos preocupar com a segurança. 🐹💻 🔍 Destaques da comparação: - Consulta SQL Única: Mais eficiente em tempo de execução e uso de memória. - CRUD DAO: Uso moderado de memória, mas mais lento. - GORM: Mais fácil para desenvolvimento, mas maior tempo de execução e consumo de recursos. A documentação está disponível em português e inglês. 📊 Confira os resultados e o projeto no GitHub: https://lnkd.in/dhti4bXW Há muito mais testes a serem feitos. Qualquer feedback ou sugestão são bem vindos! #Golang #DatabasePerformance #PostgreSQL #SQL #GORM #SoftwareDevelopment #Benchmarks #DataScience #Coding #TechResearch #Docker #Python #ORM #CRUD

I completed the first and second modules (System Design + Networking) of the iOS Lead Essentials program 🧑‍💻! Here's a summary of what I learned so far 👇 - The fundamentals of good system design and architecture. How to think, design, and draw diagrams like a software architect. - Networking best practices to develop, maintain, and test a clean networking layer in iOS apps with key frameworks such as URLSession, URLProtocol, Decodable, and third-party code. Also, how to work effectively with backend teams. Click to see more: https://lnkd.in/gUrBDGuJ

Introduction to Networking in Node.js 🌐 I’m diving into networking in Node.js this week, starting with the basics of creating an HTTP server. It’s amazing how Node.js makes handling network requests so simple! Using the built-in http module, we can quickly set up a server to handle client requests. 🚀 Stay tuned as I walk through the process step by step. #Nodejs #Networking #BackendDevelopment

🌟 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? Let me know your favorite use cases or tips! #NodeJS #JavaScript #LearningJourney #WebDevelopment #Modules #CommonJS #ESModules

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.

🌟 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

A fascinating project involving APIs to filter registered podcasts, built with Node.js and TypeScript, without using any frameworks. This approach allowed me to gain a deeper understanding of what’s happening “under the hood.” I set up the server using native Node.js HTTP modules, configuring routes from controllers, and carefully handling and configuring status codes to ensure accurate responses to the frontend, following best practices. Additionally, I structured the entire project into layers with a focus on Single Responsibility to keep it scalable and easy to maintain. It was an incredibly rewarding experience, watching the server evolve from the ground up—growing through controllers, routes, services, repositories, and much more.

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

Hands-on Node.js: The Node.js Introduction and API Reference by Pedro Teixeira When diving into Node.js, Hands-on Node.js by Pedro Teixeira is one of those resources that feels like a robust, grounded companion, guiding you through each stage of development. As someone who has explored various Node.js resources, this book struck me with its clarity and practicality, especially for developers seeking a hands-on approach.

🚀 Mastering Node.js: Building a Simple Note Management App I’ve been working with Node.js to build a simple CLI app for managing notes. Here’s a breakdown of how I handled file I/O using fs (file system) to create, read, update, and delete notes from a JSON file. Here's the key flow: Read Notes: Read a JSON file (notes.json) and parse it into an array. Write Notes: Save notes to the file after every addition, update, or deletion. Add Note: Push a new note with a title, content, and unique ID. Update Note: Find the note by title and update its content. Delete Note: Locate the note by title and remove it from the list. This simple note management system works synchronously to ensure that the data is always up to date. Perfect for those just getting started with Node.js and file operations! Check out the code below and give it a try. This project is a great introduction to handling file operations in Node.js! #NodeJS #JavaScript #BackendDevelopment #Programming #Coding #Tech 💻 Code:

Currently, I did a project using Java and React. This project is simply, only to realize a math operation or generate a random string. The ideia is show how I built the backend and front-end, with JWT authentication, logs and project architecture, in addition, create a docker image to boths. The repository from backend: https://lnkd.in/dmjNvPK4 The repository from front-end: https://lnkd.in/dBtPSpqH To facilitate, I did the deploy in AWS and I'll let there for some days. You can use the project access this link: http://54.236.117.98:3000/ There are 10 users with username: [email protected] [email protected] [email protected] ...
